The M2540A ultrasound system comprises a cart, a system control panel, and a monitor. A foot
pedal on each caster locks and unlocks the front cart wheels. All four wheels swivel. The system
control panel and the monitor adjust up and down and swivel as a unit, and the monitor tilts and
swivels on its mount.
The cart’s lower enclosure contains the M2540A’s computer, disk drives, and ultrasound
generating and processing boards.
CD-RW and floppy disk drives are standard equipment.
Optional peripheral components include a video cassette recorder, various types of printer, a
foot switch, and a magneto-optical disk (MOD) drive. The VCR is available in either NTSC or
PAL configuration. For a complete list of optional components, see “Optional Peripherals” on
page 201.
Most peripheral devices mount on top of the lower enclosure. The optional plain-paper printer
is not mounted on or powered by the system, but is connected from a remote location.
The Resident Self Test (RST) software verifies system performance and helps diagnose problems.

General Information: System Description
The system control panel includes four numbered option buttons whose functions are assigned
by the customer. See the online Help file for details on configuring these controls.
System
Description
Major ultrasound system components are described on the following pages. These descriptions
include important features of the cart, monitor, system control panel, Physio module, e-box, and
system power supply.
References to the left and the right sides of the system are as viewed from the front of the cart.
Cart
The cart supports the system and acts as the chassis into which all system components are
installed and interconnected.
A height adjustment lets you adjust the system control panel and monitor for operator comfort.
An Input/Output (I/O) panel at the rear of the cart contains three connectors for
communication between the system and a network, and for controlling certain legacy printers.
The foot switch port, an equipotential lug, and the system ground lug are also on the I/O panel.
The panel is at the center of the lower part of the cart, and is accessible to the system operator.
See “I/O Panel” on page 45 for more information about the I/O panel.
Cart Wheels
Four wheels at the cart base provide system maneuverability and braking. All four wheels swivel,
and the front wheels can be fixed straight and locked. Foot pedals on the two front wheels lock
and unlock the front wheels to prevent the cart from rolling. Locking the wheels immobilizes the
system during patient procedures.
PC
The M2540A uses a personal computer (PC) as a central processor. The PC houses several
components as standard equipment. These include the acoustic processor input/output (APIO)
board, a video card, a CD-RW drive, and a floppy disk drive.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 8
General Information: System Description
The optional Physio module installs in one of the PC’s front drive bays. An optional
magneto-optical disk (MOD) drive can also be installed in one of the drive bays. The VCR option
includes three boards that reside in the PC’s PCI slots, and a VCR that mounts on the cart.
See “Internal PC” on page 39 for more detailed information about the PC and its components.
System Monitor
The monitor at the top of the cart is a 15-inch color display mounted on a “twivel” assembly.
The twivel allows tilt and swivel positioning of the display for ease of viewing.
e-box
The e-box houses the scanner circuit boards, and is accessible by opening the door at the right
rear of the cart.
There are several circuit boards in the e-box:
System Control
Panel
•
Two transmit and receive (TR) boards
•
A beam processor/acoustic processor (BPAP) board
•
A demodulator board
•
The system motherboard
•
The distribution board
The system control panel at the top front of the cart is a replaceable, self-contained module. See
“Replacing the System Control Panel” on page 159. The panel interfaces with the imaging system
through a USB cable that connects to the internal PC. Power for the trackball is provided via the
USB cable. All the other control-panel functions are powered by a cable from the system power
supply.
The system control panel contains a backlit alphanumeric keyboard, slide controls, rotary
controls, hard-coded and software-driven keys, and a trackball.

General Information: Optional Peripherals (VCR, Printers, and Image Devices)
Physio Module
The optional Physio module (see “Physio Module Option” on page 43) installs in one of the PC
drive bays. The front panel of the module bears two input connectors:
•
A 3-lead ECG physio connector
•
An auxiliary analog input (standard ¼-inch phone jack)
An externally generated auxiliary analog input signal using the phone jack can substitute for the
3-lead ECG physio connector at the front panel. You can also input an auxiliary ECG waveform
from an external patient monitor and display it, in all modes. The R-wave from this signal can
serve as a time reference for the system.
Power Supply
The power supply is an enclosed, self-contained, replaceable module that mounts under the
e-box at the right side of the cart. It accepts AC input sources from 100 V to 240 V, at 50 Hz or
60 Hz.
The power supply provides all required AC and DC voltages to the system. Three switched
120 VAC outlets for powering the monitor and two peripheral devices are at the rear of the
power supply. An unswitched outlet powers the M2540A’s internal PC. When the system is shut
down, only the 120 VAC outlet to the PC is enabled. A green LED on the left front of the power
supply lights when the power supply is energized.
Optional
Peripherals
(VCR,
Printers, and
Image
Devices)
The M2540A supports several types of optional peripheral devices:
•
VCRs, including NTSC-format and PAL-format models
•
Thermal color and thermal black-and-white printers
•
Various biopsy kits (See “Supplies and Accessories” on page 202.)
•
A magneto-optical disk (MOD) drive for data storage
“Optional Peripherals” on page 201 lists all peripherals supported by the ultrasound system.
Some peripherals mount on a shelf below the system control panel.

Preset
Functions
Page 10
General Information: Preset Functions
The ultrasound system includes programmable presets that configure the system for best imaging
results in a particular situation. Activating a preset initializes system settings to values that are
optimal for a chosen exam. The factory installed software includes several presets, tailored to
different applications. The user can define as many as 20 additional presets in each of 8 exam
types, to adjust system variables (including acoustic power) to any required configuration.
For specific information regarding the configuration and use of presets or other features of the
system, see the online Help file.
NOTE Backing up presets to a floppy disk safeguards them and preserves the operator’s
preferred configurations. If preset configurations are subsequently changed, they can be
quickly restored from the backup copy, without having to reset them manually. Keeping
a backup copy also eliminates the need to manually reconfigure the presets after a
software upgrade. See “Backing Up and Restoring Presets” on page 143 for the
procedures to back up and restore presets.

Transmit
Power
(Acoustical)
Page 27
Safety: Transmit Power (Acoustical)
Acoustic output, expressed as an index, is displayed on the screen to allow the best possible
diagnostic image with minimal power output. A display standard presents this index using one of
the following four power indices:
•
Mechanical index (MI)
•
Thermal index for soft tissue (TIS)
•
Thermal index for bone (TIB)
•
Thermal index for cranial bone (TIC)
The index setting on the System Setup menu selects the power index used. The displayed
index is based on this setting and on preset configuration and imaging mode.
NOTES
• The power index setting on the System Setup menu selects any of the four power indices
for display at any time.
•
The Power rotary control at the right side of the system control panel is the only control
that affects transmit power level.
For additional information on acoustical power settings and power index, see the Philips Safety
and Standards Guide.
Acoustic
Exposure
Although no harmful effects have been demonstrated for any of the ultrasound frequencies,
intensities, and exposure times used in examinations with Philips ultrasound systems, Philips
recommends that you consider the following, and use the lowest ultrasound exposure that
produces diagnostically acceptable information:
•
Use diagnostic ultrasound only when there is a good medical reason.
•
Reset the controls at the start of every examination.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 28
Safety: AIUM/NEMA Output Display Standard
•
Reduce exposure time, independent of acoustic index value.
•
Use techniques that let you collect clinical data quickly and end the examination promptly.
•
Select a transducer that provides good resolution and focal depth for the region of interest.
Then use the imaging controls to fine-tune image resolution.
For more detailed information on acoustic exposure, see the Output Display Standards and ODS
Acoustic Tables booklet.
AIUM/NEMA
Output
Display
Standard
In compliance with the Output Display Standard (ODS) jointly proposed by the American
Institute of Ultrasound in Medicine and the National Electrical Manufacturers Association, the
Philips ultrasound system displays power output indices related to the potential for bioeffects.
Real-time information related to the power output is displayed on the monitor, indicating the
type of index displayed and the value of that index for the acoustic output currently being used.
For example, if the output corresponds to a mechanical index of 0.8, the following is displayed:
MI: 0.8
The displayed index is one of four types: MI, TIS, TIB, or TIC. These ultrasound abbreviations
conform to the AIUM/NEMA Output Display Standard.
Soft tissue thermal index (TIS) is used in cardiac, fetal, and abdominal scanning.
The thermal index for bone (TIB) is used in applications such as second or third trimester fetal
scanning and neonatal cephalic (through the fontanelle) scanning.
The cranial bone thermal index (TIC) is used for transcranial imaging.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 29
Safety: AIUM/NEMA Output Display Standard
NOTE The power index displayed on the screen depends on the preset type, the active
transducer type, the imaging mode, and the selected power index. Any of the four
power indices is selectable for display at any time, using the power index setting in the
System Setup menu.
Automatic
Index Selection
For automatic selection of a power index based on system mode, the user selects the power
index setting of Normal from the System Setup menu. This directs the system to choose an
index based on the active preset and imaging mode.
When MI is Displayed With the Normal Setting
MI is displayed if any of the following conditions exist:
•
2D Only is the active imaging mode.
•
Black-and White MMode Preview is the active imaging mode.
•
Black-and White Doppler Preview is the active imaging mode.
•
Black-and White Doppler 2D Live is the active imaging mode.
When TIS is Displayed With Normal Setting
If none of the conditions in “When MI is Displayed With the Normal Setting” on page 29 exist, if
no transcranial preset is active, and any of the following conditions exist, TIS displays:
•
Color is turned on.
•
Angio is turned on.
•
MMode Trace is the active imaging mode.
•
Doppler Spectral is the active imaging mode (with 2D Live off).
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 30
Safety: Explosive Hazards
When TIC is Displayed With Normal Setting
If none of the conditions in “When MI is Displayed With the Normal Setting” on page 29 exist, a
transcranial preset is active, and any of the following conditions exist, TIS displays:
•
Color is turned on.
•
Angio is turned on.
•
MMode Trace is the active imaging mode.
•
Doppler Spectral is the active imaging mode (with 2D Live off).
If the user selects an ODS setting other than Normal, the selected index type is used as the
preferred acoustic power display format, regardless of the mode, the transducer, or the preset
that is selected.
The displayed index value does not provide an exact value of the potential for adverse bioeffects
in the patient. However, for any patient, the higher the value, the higher the potential for adverse
bioeffects. The user can minimize the potential for bioeffects by keeping the index value as low as
possible, by choosing the right transducer and making adjustments. Minimizing examination time
also minimizes bioeffects.
WARNING
The ODS power index formulas were defined for reasonable worst case patient conditions. It is
likely that a particular patient's actual conditions are better than indicated by the index. The
operator should be aware of patient conditions that mitigate the actual exposure.
Explosive
Hazards
Observe the following practices to avoid explosive hazards:
•
Do not operate the system in the presence of flammable anesthetics.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
•
When using the imaging system in the operating room, do not switch system power on or
off. Be sure system power is on before the operation starts, and leave it on for the duration
of the procedure.
WARNING
Do not use the foot switch in the operating room.
Electrical
Warnings
Observe the following precautions to prevent electric shock:
WARNINGS
Peripheral
Connections
Page 31
Safety: Electrical Warnings
•
Only qualified service personnel should remove system covers (trim and service panels).
Accidental contact with electrical circuits inside the system could cause serious injury.
•
Use only the power cords supplied with the system, and connect them only to properly
grounded electrical outlets.
•
Failure to follow these warnings can affect both patient and operator safety.
•
Do not connect the ultrasound system to the same circuit used for life support devices.
Peripherals (such as a VCR or a printer) typically meet general electrical safety usage
requirements, but do not meet medical device standards. Therefore, do not use system
peripherals within six feet of a patient unless the peripherals receive power from an isolated
power outlet on the imaging system, or from an isolation transformer that meets medical safety
standards. The 120 VAC outlets on the power supply are isolated. The specific peripherals listed
in “Optional Peripherals” on page 201 meet medical device standards when installed in the
system as recommended.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Glutaraldehyde
Exposure
Page 32
Safety: Glutaraldehyde Exposure
The United States Occupational Safety and Health Administration (OSHA) has issued a
regulation dealing with levels of acceptable glutaraldehyde exposure in the working environment.
Philips does not sell glutaraldehyde-based disinfectants with its products. However, this type of
disinfectant is recommended for disinfection of transesophageal (TEE) or endocavity
transducers.
To minimize exposure to glutaraldehyde fumes, make sure the area is well ventilated and use
appropriate eye and skin protection.
Moving the
System
Although the system is designed to be mobile, remember that it is very heavy, and that you
must take precautions when moving the system.
The ultrasound system has been designed to be as lightweight and mobile as possible. However,
the system weight—including the weight of the monitor, a printer, and a +VCR—is
approximately 100 kg (220 pounds). Because of this weight, you must use caution when moving
the system, since the ability to move any ultrasound machine is directly related to an individual’s
size and strength.
Some sonographers, particularly those weighing less than 100 pounds, have stated that they
injured their backs moving similar systems. These complaints could not be directly tied to one
particular incident. They do, however, point out the need to be careful in transporting medical
equipment such as an ultrasound system.
Before Moving
the System
To move the system, take the precautions listed in the following sections, and
•
Before moving the system, be sure to remove any loose equipment from the top of the system, disconnect the system power cord, and disconnect all external devices.
•
Before transporting the system in a vehicle, remove the monitor and all transducers from the
system and put them in a packing box.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 33
Safety: Moving the System
When Moving
the System
This system is equipped with a front handle and brakes on the front wheels.
WARNING
Never strap or secure the system at any point above the peripheral tray.
Always use the handle at the front of the cart to move the system from place to place.
NOTE Use caution and follow these steps when moving the system from patient to patient.
1. Unlock the wheel locks before moving the system.
2. Make sure the control top is locked, to prevent its pivoting during transport.
3. Engage the track locks on the front wheels to ease straight-line travel.
4. Push with the handle at the front of the cart.
5. After the system is in position, engage the wheel locks to immobilize the system, and unlock
the control top to allow it to pivot.
Moving on
Ramps or
Uneven Surfaces
Do not move the system over uneven elevator entrances by lifting the machine or any part of the
machine.
System Tilting
The system has been tested for stability using the IEC 60601-1 test protocol. Following this
protocol, the system will not tip over on an incline of up to 10 degrees in any direction. When
this amount of incline is exceeded, there is a potential for the system to tip over.
Always use two people when moving the ultrasound system up and down ramps longer than 20
feet or steeper than 5 degrees. (Wheelchair ramps are usually less than 5 degrees.) Avoid ramps
that are steeper than 10 degrees, to eliminate the danger of the system tipping over.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 34
Safety: Moving the System
WARNING
Use care when tilting the system for an incline. The amount of incline allowable to prevent
tip-over is 10 degrees. Moving the system over a roadside curb or other small but steep incline
can cause the system to exceed 10 degrees of incline.
Transporting
the System in a
Vehicle
Always engage the wheel locks while transporting the system in a vehicle, and use restraining
straps to secure the system in place. Do not rely on the wheel locks to hold the system on
inclines greater than 5 degrees.
Be sure that the transporting vehicle can handle the weight of the system (or systems) plus the
passengers.
Be sure the load capacity of the loading lift can accommodate the weight of the ultrasound
system. A minimum capacity of 550 pounds is recommended.
Always secure the ultrasound system while it is on the loading lift so that it cannot roll. Make
sure the control top is locked, to prevent its pivoting. Engage the wheel locks and use wood
chocks, restraining straps, or other similar types of constraints as an added safety measure. Do
not attempt to hold the system in place manually.
WARNING
Never strap or secure the system at any point on the control top or monitor.
Load and unload the ultrasound system while the transporting vehicle is parked on a level
surface. The system’s weight can easily cause it to roll on any incline.
The system’s weight on an extended loading lift may cause the transporting vehicle to tilt, which
could cause personal injury or system damage.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
WARNING
Page 35
Safety: Electromagnetic Compatibility
Never ride on a loading lift with the system. Your weight combined with the system's weight can
exceed the lift's load capacity.
Be sure the ultrasound system is firmly secured while inside the transporting vehicle. Any
movement, combined with the system’s weight, could cause the system to break loose.
NOTE If you use the ultrasound system in a mobile van, follow the same fundamental
transporting precautions listed in the sections above.
Electromagnetic
Compatibility
This system has been tested for electromagnetic compatibility (EMC) according to the
international standard for EMC with medical devices, as determined by the International
Electrotechnical Commission (IEC 60601-1-2). This IEC standard has been adopted in Europe as
the European Norm EN 60601-1-2.
Avoiding
Electromagnetic
Interference
Medical devices can generate or receive electromagnetic interference (EMI). The EMC standards
describe tests for both emitted and received interference. Emission tests deal with interference
generated by the device being tested. The Philips ultrasound system does not generate
interference based on the tests described in the standards.
Ultrasound systems are designed to receive radio frequency (RF) energy and are therefore
susceptible to EMI generated by other RF energy sources. Examples of other sources of EMI are
medical devices, information technology products, and radio and television transmission towers.
Tracing the source of radiated interference can be a difficult task.
See “Electromagnetic Interference” on page 137 to identify sources of EMI.
Only a physician can determine if an artifact caused by radiated interference has a negative
impact on image quality and the subsequent diagnosis.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual

Safety: Restrictions for Use
Restrictions
for Use
The M2540A ultrasound system is subject to certain restrictions that are described in the
following sections.
Immunity Level
Test Results
The EMC standards require that manufacturers of patient-coupled equipment specify
electrostatic discharge immunity levels for their systems. This type of device is designed to
receive and amplify low-level signals in the same bandwidth as the interference to which it is
susceptible.
Immunity is defined in the standard as the ability of a system to perform without degradation in
the presence of an electromagnetic disturbance. Degradation in image quality is a qualitative
assessment that can be subjective. The simplest way to assess degradation is to note when the
first sign of an artifact is seen. This method has two advantages: It removes the issue of subjective
decision-making and provides the most stringent test results.
Caution should therefore be taken in comparing immunity levels of different ultrasound systems.
The criteria used for measuring degradation are not specified by the standard, and can vary with
the manufacturer.
Philips has tested each class of transducer for every operating mode over a wide range of
frequencies. This testing showed PW Doppler to be the most susceptible to radio-frequency
interference.
Please see the Philips Safety and Standards Guide shipped with your system for additional
information about compliance with EMC standards.
Electrostatic
Discharge
Electrostatic discharges can cause the ECG heart rate display to increase by 10 to 15% for a few
seconds after the discharge. However, the ECG heart rate display returns to normal within four
seconds.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Electrosurgical Units
Page 37
Safety: Electrosurgical Units
Electrosurgical units (ESUs) and other devices intentionally introduce radio frequency
electromagnetic fields or currents into patients. Because imaging ultrasound frequencies are also
in the radio frequency range, ultrasound transducer circuits are susceptible to radio frequency
interference. While an ESU is in use, the noise generated severely interferes with the
black-and-white image and completely obliterates the color image.

Theory of Operation: TR Boards
VCR-Option Components in the PC
The VCR option includes several cards inside the PC and an adapter that connects to the SVGA
output of the PC’s graphics adapter board. See Figure 4-1 on page 48 for a detailed
representation of how the VCR option’s components function in the ultrasound system.
The following cards are part of the VCR option, and reside in the PC’s PCI slots:
•
A sound card that receives audio from the VCR, and supplies sound to the VCR
•
A video capture board that receives S-Video signals from the VCR
•
An SVGA-to-S-Video card that converts the SVGA signal from the graphics adapter board (in
the AGP slot) to S-Video for the VCR
•
An SVGA adapter that connects the graphics adapter board to the SVGA-to-TV video card
and to the monitor
See “VCR Option Parts” on page 198 for a list of all the components of the VCR option.
Optional Drive-Bay Components
The PC’s drive bays accept the following components:
TR Boards
•
The Physio module that provides ECG monitoring capability. The drive bay’s power connector powers the module, but the module does not use the drive bay’s data port. The module
communicates with the ultrasound system through a USB cable to the PC motherboard. See
“Physio Module Option” on page 43, and Figure 4-3 on page 51 for detailed information on
the Physio module.
•
A magneto-optical disk (MOD) drive that allows archiving of images, studies, and reports on
removable disks. The MOD uses the drive bay’s data and power ports.
The M2540A’s e-box contains two transmit-and-receive (TR) boards. Each has a connector that
plugs into the motherboard and another connector that passes through the motherboard and
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 41
Theory of Operation: TR Boards
plugs into the distribution board. The two boards form electronic beams of the transmit and
receive signals. Each TR board contains 64 transmitters and 32 preamps multiplexed into 64
receive channels. This allows multiplexing the system’s 64 active channels into 128 element
arrays. Each receive channel consists of time gain compensation (TGC) amplifiers, low pass
filters, 10-bit A/D converters, and one eighth of a digital beam-forming circuit. Each TR board
sends on its output bus a value that is the sum of the data from its 32 channels plus its 18-bit
input bus. The last TR board in this chain outputs the final summed radio-frequency (RF) data to
the demodulator board.
The transmit and receive beam-forming coefficients for acoustic lines are downloaded on the
coefficient bus from the BPAP board.
The BPAP board generates the timing to start and stop each firing line, and sends the transmit
signal to the TR board, through the distribution board and the connector modules to the
transducer. Analog drivers generate the transmitted RF data. A digital timing generator delays
and times each of the analog drivers. The delay generators receive the appropriate delay values
from the BPAP for each channel. The system power supply controls the amplitude of the
transmitted waveform.
The received signal is preamplified, TGC amplified, low-pass filtered, and digitized (in all modes
except CW). The BPAP board generates TGC control signals through the demodulator board.
After being digitized, the signal on each line is delayed appropriately. The outputs of all channels
are daisy-chained together to sum the outputs. The RF data output of one TR board is the input
to the next TR board, and the outputs of the TR boards are summed to form the received beam.
The summed output signal (RF DATA) goes to the demodulator board.
The CW Doppler signal is mixed to an analog intermediate frequency (IF) signal. The CW
Doppler output is a single differential signal routed to the demodulator board.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
BPAP Board
Page 42
Theory of Operation: BPAP Board
The beam processor/acoustic processor (BPAP) board contains two processors. One of them
controls beam-forming, line-to-line operation. The other handles the processing of scan
conversion, color flow, and Doppler signals.
The BPAP board does the following:
Omni TEE
Circuitry
•
Provides the interface between the PC and the TR boards
•
Provides the interface between the PC and the demodulator board
•
Receives control data sets from the PC, processes them for specific register values, and
sends them to the TR boards
•
Houses the transesophageal echo cardiography (TEE) transducer interface circuitry (TEE
motor control and temperature monitoring)
•
Houses the transducer ID circuitry
•
Detects the presence of standalone transducers
•
Houses electronic switching that allows selection of a single active transducer from the four
that can be connected
•
Controls the high-voltage output from the system power supply
The Omni Probe control circuitry on the BPAP board supplies power to the TEE transducer's
motor. It also measures the position of the angle-position sensor. The signal is digitized and sent
to the APIO board for monitoring by the PC.
The beam processor circuitry monitors thermistors in the transducer and insures that high
voltage is not applied to the transmitter unless the thermistor values are within limits.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual

Theory of Operation: Demodulator Board
Demodulator
Board
The demodulator board performs image and Doppler demodulation for BMode, MMode, PW
and CW phased and non-imaging Doppler modes, and color flow mode. It sends a baseband data
stream to the BPAP board.
The demodulator board contains the following:
APIO Board
•
Digital filters and mixers for demodulating 2D, color flow, and PW RF data
•
The independent transducer CW Doppler electronics and steerable CW detector functions
•
The 120 MHz system clock. The clock signal is distributed to the TR and BPAP boards.
•
Circuitry that generates TGC signals
The acoustic processor I/O (APIO) board is the token ring interface between the system’s PC
and the e-box. The APIO board also handles input from the foot switch’s three control buttons
(via the I/O panel) and forwards them to the PC. The board also generates trigger signals for
legacy printers.
The board handles these signals from the PC:
Physio Module
Option
•
The R-wave pulse from the physio module that it sends to the BPAP board
•
The DC on-off bit that it sends to the power supply
•
Commands that program the BPAP board at startup
•
Acoustic data from the BPAP board for the acoustic imaging display
The self-contained Physio module resides in one of the PC’s drive bays. The module receives
power from the drive bay’s power connector, but it communicates with the system through a
USB cable to the PC’s motherboard. A shielded and grounded enclosure prevents
electromagnetic interference. See Figure 4-3 on page 51 for a detailed representation of the
module’s functions and connections.

Theory of Operation: System Motherboard
Primary
Functions
Connectors
The module’s primary functions are as follows:
•
Process electrocardiogram (ECG) signals from patient electrodes and deliver the data to the
M2540A’s PC
•
Send a detected R-wave trigger to the APIO board for frame triggering in various scanning
modes
•
Provide gain control for ECG waveforms
The Physio module has two connectors on its front panel:
•
The ECG-input connector is a round, 12-pin connector that is isolated from chassis ground.
•
A ¼-inch phone plug jack accepts auxiliary input and has both signal and shield grounds.
System
Motherboard
This board connects all data paths between the TR boards, the BPAP board, and the distribution
board. It is also the distribution point for DC power and ground to all boards (the BPAP board
and distribution board also receive power directly from the system power supply.). It also sends
filtered high voltage to the TR boards.
Distribution
Board and
Connector
Modules
The distribution board passes transducer signal inputs to the imaging system. The system power
supply provides high voltage directly to the distribution board to fire transducers.
Signals that pass through this board include
•
Transducer identification signals from the BPAP board to and from the transducer
•
Transmit and receive signals from the TR boards to the active transducer
•
TEE motor-control and temperature-sense signals from the BPAP to and from the TEE transducer

•
An RJ-45 (CAT 5) connector for connection to a LAN
•
A BNC connector that carries composite video signals for a legacy printer
•
A BNC connector that carries trigger signals for a legacy printer
•
A 9-pin D connector for the optional foot switch
The system control panel contains the circuitry to process control inputs, the system keyboard,
rotary and slide controls, and the trackball. A USB cable carries control inputs from the control
panel to the PC. An auxiliary cable carries power from the system power supply. The system
control panel circuit board also carries the amplifiers for the system’s stereo speakers.
All control inputs and LEDs are controlled by the system’s PC, and their functions are
determined by resident control-panel and system software.
Circuit boards inside the system control panel are not field serviceable or replaceable. The
entire assembly, including circuit boards, bezel assembly, and labels, is available as a replaceable
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 46
Theory of Operation: Power Supply
part. Rotary and sliding knobs, rotary encoders for the knobs, the trackball assembly, and the
trackball cable are all available as separate parts.
Power Supply
The M2540A power supply is a self-contained unit that accepts AC input from 90 to 264 V, at 50
or 60 Hz, and supplies 120 VAC at 60 Hz to the system’s PC, monitor, and two peripherals. It
also provides all DC power required by system components. No switch settings are required to
configure the power supply for different AC mains; the power supply automatically adjusts to use
the power connected to it. Except for the 120 VAC to the PC, all power output is activated by a
signal from the PC. The system cooling fan is the only serviceable part on the power supply. See
Figure 4-1 on page 48 for details of the power supply’s outputs. The power supply activates when
it receives an “AWAKE_N” signal, which is generated by the PC, and then sent through the BPAP
board to the power supply.
The system power supply does the following:
•
Provides DC power to all system electronics through the system motherboard and the BPAP
board
•
Provides DC power directly to the system cooling fan
•
Provides high voltage to the distribution board for multiplexing transducers
•
Isolates AC mains from secondary AC and DC circuitry
•
Transforms primary voltages to secondary voltages
•
Filters line AC
•
Provides an isolated 120 VAC unswitched outlet to power the internal PC
•
Provides three isolated 120 VAC switched outlets to power the monitor and two peripherals

Transducer
Safety Testing:
Test Setup
and Theory
This section provides background and supporting information for the transducer leakage tests in
Section 6, “Performance Tests”; this information is not required to perform the tests.
In transducer safety tests, a container filled with saline solution functions as a conductive
medium (see Figure 4-4 on page 53). The solution penetrates any faults in the transducer
insulation and provides an electrical path between the submerged lead wire and the grounded
inner transducer shield.
The test for transthoracic and endocavity transducers differs from the test for TEE transducers
only by the extent that the transducers are submerged in the test solution.

Theory of the Transducer Leakage Current Test
Leakage current Ichassis, driven by the line supply, flows through the stray capacitance C between
the primary wiring and the system’s metal chassis.

The leakage current normally flows from the chassis safely out through the ground wire. If there
is a fault in the transducer insulation, some of the current follows this path and is measured by
the safety analyzer. This Itransducer is still fairly low, unless the chassis is not properly grounded.

Imposing an open neutral condition prevents all system current from flowing. This creates a
higher potential for leakage current Ichassis. Most flows safely through the ground wire; some
flows through the transducer. This Itransducer is still fairly low, unless the chassis is not properly
grounded.

With the transducer circuit disconnected, all of the leakage current Ichassis flows through the
analyzer by way of the ground wire.
In the 1st single fault condition transducer leakage test (Figure 4-6 on page 56), all the leakage
current Ichassis flows through the analyzer by way of the transducer. In that condition, only the
resistance or impedance of the respective paths varies.
•
If the transducer sheath is intact, its resistance is high, and Imeasured in the transducer leakage
test is low when compared with Imeasured in the ground wire leakage test.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 58
Theory of Operation: Transducer Safety Testing: Test Setup and Theory
•
If the transducer sheath is compromised, its resistance is close to that of the ground wire.
Transducer leakage current equaling 80% or more of ground wire leakage current indicates a
fault or break in the transducer insulation.
Sheath integrity is tested this way because there could be a break in the transducer sheath
causing significant Itransducer, and yet that leakage current could still be within acceptable limits.
Comparison to the ground wire leakage current is the only way to ensure sheath integrity.

“Electrical Safety Tests” on page 89
•
“PC Diagnostics” on page 105
•
“Resident Self Tests” on page 107
The tests described on the following pages are part of a comprehensive preventive maintenance
program. They detect abnormalities that could prove dangerous to patient or operator.
NOTES
• The system power supply is a self-contained unit that is safety-tested by its manufacturer. No
further safety testing is needed when the power supply is installed or replaced.
•
After any service or maintenance, perform the required tests to assure that system safety
and functions are not compromised.
•
Inspect power cords frequently, especially at their ends.
The following safety tests are described in this section:
•
The Chassis to Ground Resistance test checks the entire system for electrical resistance
between the chassis and ground. See “Chassis to Ground Resistance Test” on page 90.
•
The Ground Wire Leakage Current test checks the entire system for leakage on ground
leads. See “Ground Wire Leakage Current Test” on page 92.

•
The ECG Lead Leakage Current test checks ECG leads connected to the optional Physio
module for electrical leakage. See “ECG Lead Leakage Current Test (Source)” on page 94.
•
The ECG Lead Isolation Leakage test checks ECG leads by applying voltage from the mains to
the leads, to assure that the system is isolated from such voltages. See “ECG Lead Isolation
Leakage Current Test” on page 96.
•
The Transducer Leakage Current test checks a transducer for electrical leakage while it is
connected to the ultrasound system. The system sends normal operating voltages to the
transducer, which is tested for leakage. See “Transducer Leakage Current Test Procedure”
on page 100.
•
The Transducer Isolation Leakage Current test checks a transducer for electrical leakage by
applying mains voltage to the leads, and checking the transducer for leakage. See “Transducer
Isolation Leakage Current Test” on page 102
All tests can be performed using commercially available safety analyzer test equipment. Basic
measurements can be performed with multifunction instruments like the HP 3469A multimeter.
NOTE These procedures require a safety analyzer. Routinely use a safety analyzer as a final
step in any repair or upgrade, to maintain agency approved status. The safety analyzer is
also useful in detecting abnormalities of line voltage, grounding, and total current loads.
Follow the instructions of the analyzer manufacturer.
The limits referenced in these tests are prescribed by UL, CSA, and IEC. Local regulations may
require additional tests.
Chassis to
Ground
Resistance Test
This test checks the entire system for electrical resistance between the chassis and ground.
Figure 6-1 on page 91 shows the basic electrical concept of the ground resistance test. Use a
safety analyzer and complete the procedure that follows the figure.

Performance Tests: Electrical Safety Tests
WARNING
Some users routinely perform a safety-earth or ground-bonding test at currents in excess of
10 amps. Test currents in excess of 1 amp will likely exceed the impedance limit specification,
and can damage the RFI protection finger contacts. Exposed metal on the transducer assembly,
including the connector, are for RFI and are not safety grounds.

Performance Tests: Electrical Safety Tests
4. Make the appropriate connections between the analyzer and the ground lug on the
ultrasound system’s I/O panel.
5. Read chassis ground resistance in milliohms. Flex the ultrasound power cord during the test
to detect intermittent changes in resistance value.
6. Record the highest resistance value measured in step 5. Check that the highest resistance
value is within the limit specified in Figure 6-1on page 91.
NOTE If the reading exceeds the specified limit, check the power cord and the associated
primary wiring.
A comprehensive ground impedance measurement can be performed using the safety analyzer.
The impedance test drives a load current through the ground wire while measuring the AC
voltage drop across the entire length of the power cord and to the system chassis. The reading
will be in milliohms.
Ground Wire
Leakage
Current Test
This test checks the entire system for leakage on chassis ground wires. Figure 6-2 on page 93
shows the basic electrical concept of the test. Use a safety analyzer and complete the procedure
that follows the figure.
CAUTION
If the safety analyzer is used for an extended period, it may be damaged by the high current draw
of the system.
WARNING
This test can be hazardous. Avoid any contact with line voltage. Any time during the test that the
ground connection is open, do not touch the M2540A chassis or the patient cable.

Performance Tests: Electrical Safety Tests
4. Connect ECG leads to the ultrasound system, but do not connect the ECG leads to the
analyzer yet.
5. In normal polarity, perform a lead isolation test. Record the reading in microamperes. This
reading is the correction factor used in step 7.
6. Connect all ECG leads to the appropriate jacks on the analyzer and perform a lead isolation
test. Record the reading in microamperes.
7. Subtract the step 5 correction factor from the step 6 reading to get an accurate isolation
leakage measurement. Record this value. Check that the value is within the limit specified in
Figure 6-4 on page 97.
NOTE Some analyzers do not require subtracting the correction factor from the lead isolation
reading. Refer to the analyzer’s documentation for more information.
Transducer
Tests
Two electrical leakage current tests for transducers are described in this section. To insure
patient safety, it is very important to verify the integrity of the insulating layers of all transducers.
When performing the safety tests, saline solution in a container is used as a conductive medium
(see Figure 4-4 on page 53). The solution penetrates any cracks or holes in the transducer
insulation and provides an electrical path between the submerged lead wire and the inner
transducer shield.
“Transducer Safety Testing: Test Setup and Theory” on page 52 includes supporting information
about the transducer tests. This is supplemental information, and is not required to complete the
tests.
NOTE Before proceeding with any transducer test, thoroughly inspect the transducer. If the
transducer is a TEE, check that its steering controls are working properly.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual

Performance Tests: Electrical Safety Tests
The following tools are required for transducer safety tests:
•
Safety analyzer
•
Saline holder
•
ECG lead wire
•
Saline solution. If saline is not available, mix 27 grams of table salt in 3 liters of tap water.
Transducer Leakage Current Test (Source)
This test checks a transducer for electrical leakage while it is connected to the ultrasound
system. The system sends normal operating voltages to the transducer, and leakage is measured
using a safety analyzer. Figure 6-5 on page 100 shows the basic electrical concept of the
Transducer Leakage Current test. Complete the procedure that follows the figure.

➤ Transducer Leakage Current Test Procedure
1. Set the analyzer mode to test ECG leads.
2. Plug the analyzer into an available AC wall outlet. Plug the ultrasound system power plug into
the test receptacle on the analyzer.
3. Power up the ultrasound system by starting its internal PC.
4. Plug the transducer to be tested into the ultrasound system. Connect an ECG lead wire to
the appropriate jack on the analyzer.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 101
Performance Tests: Electrical Safety Tests
5. Fill a test container with enough saline to completely cover the appropriate parts of the
transducer. Insert the exposed end of the ECG lead into the saline, and carefully insert the
transducer:
CAUTION
•
For transthoracic and endocavity transducers, submerge the head and 5 cm of the
cable. Be careful not to submerge the connector.
•
For TEE transducers, submerge all of the flexible shaft that would normally enter the
body of the patient: 100 cm for adult TEE, 60 cm for pediatric TEE.
When submerging a TEE transducer, be careful to not submerge its control handle or allow
saline to contact its control handle. Liquid inside the control handle causes corrosion and failure.
6. Set the analyzer to read leakage current in microamperes.
7. Read the current in both normal and reverse polarity, and record the highest value. Check
that the highest value is within the limit specified for Normal condition in Figure 6-5 on
page 100. (Match the transducer type symbol on the transducer connector or cable with the
symbol in the figure.)
8. Read the current with an open ground condition imposed, in both normal and reverse
polarity. Write down the highest value; this is the value for the first single fault condition.
9. Read the current with an open neutral condition imposed, in both normal and reverse
polarity. Write down the highest value; this is the value for the second single fault condition.
10. Check that the highest current value measured in step 8 and step 9 is within the limit
specified for Single Fault condition in Figure 6-5.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 102
Performance Tests: Electrical Safety Tests
Values exceeding the limits may indicate a fault in the transducer housing or the cable sheath.
To locate a fault precisely, repeat the measurement while slowly inserting the transducer into
the saline. The aberrant reading appears when the fault in the cable enters the saline.
NOTE TEE and endocavity transducers have a grounded jacket just under the outer plastic skin
of the cable. Their leakage currents can measure within the specified limits even if there
is a fault in the outer skin. Step 11 tests for this condition.
11. In normal polarity with an open ground condition imposed, measure ground wire leakage
(see “Ground Wire Leakage Current Test” on page 92). Compare this to the highest value
for transducer leakage current, Single Fault condition obtained in step 10.
If the transducer leakage is greater than 80% of the chassis leakage, there is a fault in the
transducer. To locate the fault, slowly insert the transducer in the saline, as in step 10.
Transducer Isolation Leakage Current Test
Figure 6-6 on page 103 shows the basic electrical concept of the Transducer Isolation Leakage
Current test. The transducer is submerged in a container of saline solution. Mains AC voltage is
introduced into the saline solution, and leakage current in the transducer is measured using a
safety analyzer. Complete the procedure that follows the figure.

Performance Tests: Resident Self Tests
Resident Self
Tests
The M2540A Resident Self Tests (RST) are a suite of tests that verify system hardware, using no
external instrumentation.
The RST suite consists of tests for custom M2540A hardware and software. The Resident Self
Tests also exercise individual subsystems such as the acoustic processor and the beam former
processor.
The stand-alone RST application provides access to all the tests. RST also provides information
on hardware and software, and service information on the ultrasound system. System
information, test pass and fail results, and errors can be viewed, saved, and printed by the RST
application.
Availability
The RST application is available whenever the ultrasound application is running. You can also
launch RST as the system powers up. When it starts, the RST application stops the main
ultrasound application.
Logging On
To launch the RST application, see “Launching the RST Application” on page 113. The RST
application opens with a logon window, which asks you to enter a user name and a password.
The logon window also includes a check box that skips the logon dialog the next time the RST
application is launched. Only service personnel can enable that option, and it only applies for
24 hours. After 24 hours, the logon dialog shows at launch, even if the option is selected.
Customers or service personnel who log on with a valid user name and password can create and
modify service log entries. See “Using the Service Log” on page 125.
If RST is installed on the system, logging on is not required.

Troubleshooting: Electromagnetic Interference
Electromagnetic
Interference
Electromagnetic interference (EMI) can degrade the performance of the M2540A. Answering the
following questions can help locate the source of interference:
•
Is the interference intermittent or constant?
•
Does the interference appear with only one transducer or with several transducers?
•
Do two different transducers operating at the same frequency have the same problem?
•
Is the interference present if the system is moved to a different location in the facility?
•
Can the EMC coupling path be attenuated?
A transducer placed close to an ECG cable can increase interference. Moving the ECG cable
or other medical equipment away from the transducer can reduce interference.
Answers to these questions help determine whether the problem is with the system or with the
scanning environment. Contact your local Philips service representative with a full description
and your observations.

Glossary:
Glossary
2D mode
A mode of operation where the display represents reflected ultrasound information as points of
light of varying intensity arrayed linearly, concordant with the arrival time.
Angio mode
This mode presents two-dimensional, real-time Doppler or time shift information superimposed
as colored pixels on a real-time, gray scale anatomic cross-sectional image. The colored pixel
information represents the amplitudes of the selected blood flows within the angio window.
Archive
A depository for the final reports.
Color mode
This mode presents two-dimensional, real-time Doppler or time shift information superimposed
as colored pixels on a real-time, gray scale anatomic cross-sectional image. Flow directions
toward and away from the transducer are presented as different colors on the display. The
colored pixel information represents the velocities of all the blood flows, or the flow velocities,
within the color window.
CW Doppler mode
In the Continuous Wave Doppler mode, the transducer array uses separate transmitting and
receiving piezoelectric elements. It processes the entire continuum of reflected signal
information, regardless of delay. The detected frequency shifts can produce audio signals, or they
can display graphically in a spectral trace.
Control
Any mechanism (softkey, touch key, push button, toggle, rotary knob, etc.) that changes a
parameter that, in turn, affects the displayed image.
Control setting
The current setting of an active control.
Custom preset
A preset created by the user.
Default preset
A preset created at the factory and shipped with the ultrasound system.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 207
Glossary:
Display
All the information visible on the system's monitor, including ultrasound images, measurements,
system state, patient information, etc.
Documentation
Everything produced as a result of an ultrasound exam: prints, film, VCR tape, M/O disk of
images, network archive of images, all measurements and calculations, image annotations, and
the sonographer's or physician's exam-related comments.
ECG
Electrocardiogram. The system displays a live ECG waveform if one is connected and activated.
Highlight
An indication that a control is active. Text on a CRT screen is highlighted by displaying it in
reverse video (light-on-dark, or dark-on-light, whichever is the reverse of the normal display).
Keys on the keyboard are highlighted by lighting an adjacent LED. Softkeys are highlighted by
changing the value associated with them.
Hospital information system
The computer databases and networks of an institution.
Image
An ultrasound view that is either actively displayed or archived. An image can be represented by
a single frame, a continuous loop, a 3D volume set, a Doppler spectral trace, Doppler audio, an
ECG waveform, etc.
Imaging mode
2D, Color, Angio, Mmode, PW Doppler, CW Doppler, 3D, etc.
Institution
A hospital, lab, clinic, or office.
Live imaging mode
Any unfrozen system mode that includes a two-dimensional image being created in real-time
(that is, not retrieved from VCR tape, Cine Loop memory, etc.).
Live mode
Any unfrozen system mode that shows acoustic data in real-time. Live mode includes scanning
with a non-imaging transducer. Compare to Live Imaging mode.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 208
Glossary:
Mmode
Method of image processing in which the display is recorded as a spot of light for each detected
sound pulse returning from a moving target. Produces a single-dimensional time/motion display
of detected anatomical structures.
MOD
Magneto-optical disk; a type of removable data storage.
Modality work list
A list of patient names and associated studies to occur.
Option
A piece of system functionality that a user can purchase.
Peripherals
Output devices such as VCR, MOD, hard-copy printers, network interface, etc.
Preset
A group of control settings that optimizes the system for a particular exam.
Pulsed Wave
Doppler mode
(PW)
A mode that uses pulsed ultrasound. The detected frequency shifts can produce audio signals, or
they can display graphically as a spectral trace.
Scanning window
An area of the 2D image pertaining to one of three specific modes: 2D, Color, or Zoom. The
windows pertaining to these areas are called the 2D, Flow, and Zoom windows
Select
To indicate a choice, as in choosing an item from a menu.
Setup parameters
System settings that can be configured to accommodate the user's requirements and
preferences.
Sonographer
A non-physician who has been trained to perform ultrasound studies. The sonographer performs
the patient study directly on the patient and captures results for later review by a reviewing
physician.
System text
Text showing settings of parameters having to do with system operation.
System settings
Refers to the values of a set of controls of the ultrasound system.
M2540-92000-01 A M2540 Ultrasound System Field Service Manual
Page 209
Glossary:
Transducer
The element of the ultrasound system that the sonographer places on the patient. Sometimes
called a probe. The transducer emits high-frequency sound waves into the patient and receives
their echoes. The ultrasound system controls the transmitting and receiving of the ultrasound
waves according to imaging parameters set by the sonographer. The ultrasound system
processes the received echoes to construct the displayed images, also in accordance with the
imaging parameters set by the sonographer.
Transducer icon
A graphic symbol that represents the ultrasonic transducer. This symbol indicates the scan plane
by placing it in the proper position and orientation to a body mark icon.
Ultrasound system
Any system that can perform diagnostic sonography, which is medical cross-sectional anatomic
and flow imaging using pulse-echo sound waves that are greater than 20 kHz (above the range of
human hearing).
