WARNING
PATIENT SAFETY
The concerns listed below can seriously affect the safety of patient undergoing a diagnostic ultrasound examination.
Patient Identification
Always include proper identification with all patient data and verify the accuracy of the patient's name or ID numbers when entering such data.
Make sure correct patient ID is provided on all recorded data and hard copy prints. Identification errors could result in an incorrect diagnosis.
Diagnostic Information Equipment malfunction or incorrect settings can result in measurement errors or failure to detect details within the image. The equipment user must become thoroughly familiar with the equipment operation in order to optimize its performance and recognize possible malfunctions.
Applications training is available through your
GE representative. Added confidence in your equipment operation can be gained by establishing a quality assurance program.
Mechanical Hazards
Damaged probes or improper use and manipulation of intracavitary probes can result in injury or increased risk of infection. Inspect probes often for sharp, pointed, or rough surface damage that could cause injury or tear protective barriers. Never use excessive force when manipulating intracavitary probes. Become familiar with all instructions and precautions provided with special purpose probes.
Electrical Hazards
Acoustic Hazards
A damaged probe may cause an electrically hazardous condition when coupled to the human body. Before each use, inspect the probe for cracks or openings in the cable, aperture, headshell, shaft or body.
Do not use a damaged probe to scan patients. A damaged probe may also produce inaccurate scan images.
Although there have been no confirmed adverse effects produced by diagnostic levels of ultrasound, avoid unnecessary prolonged exposure to the human body.
Follow the principle of "as low as reasonably achievable" when scanning patients. Once an optimal image is achieved, the need for increasing acoustic output or prolonging the exposure can not be justified.
Acoustic intensities for this device are below
FDA specified limits for the indicated clinical applications and will not be exceeded for any system control setting combinations.
WARNING AND PREFACE 46-030370 REV 1
EQUIPMENT AND PERSONNEL SAFETY
Risk of explosion if used in the presence of flammable anesthetics.
DANGER
Electrical
Hazard
Risk of Electric Shock
This equipment contains dangerous voltages that are capable of serious injury or death. To avoid injury:
• Do not remove protective covers. No user serviceable parts are inside. Refer servicing to qualified service personnel.
• To assure adequate grounding, connect the attachment plug to a reliable (hospital grade) grounding outlet. Do not use a two prong AC adapter.
• Do not place liquids on or above the console.
Spilled liquid may contact live parts and increase the risk or shock.
Infection Control
Prescription Device
For patient and personnel safety, beware of biological hazards while performing invasive procedures. To avoid the risk of disease transmission:
• Use protective barriers (gloves and probe sheaths) whenever possible. Follow sterile procedures when appropriate.
• Thoroughly clean probes and reusable accessories after each patient examination and disinfect or sterilize as needed.
• Follow all infection control policies established by your office, department or institution as they apply to personnel and equipment.
CAUTION: Federal law restricts this device to sale or use by or on the order of a physician.
Only qualified sonographers should perform ultrasound scanning on human subjects for medical diagnostic reasons.

Use TRACE/AREA, SET, MEAS and the TRACKBALL to mark area measurements.
By using the four different cursor patterns, four area measurements can be made on one display.
Press the TRACE/AREA key. The LED lights and the "+" cursor appear on the display.
Use the TRACKBALL to move the "+" cursor to the first measurement point.
Press the SET key. The starting point "+" cursor is locked and changes to a dot cursor.
Use the TRACKBALL and the dot cursor to trace the object to be measured.
The trace is displayed as a continuous curve, with the circumference continuously updated as you move the TRACKBALL.
Press SET. The circumference measurement is locked. The "+" cursor appears again.
Use the TRACKBALL to move the "+" cursor inside the traced area.
Press MEAS. The cursor is locked and area is measured by a graphical method. The measured value is displayed in square cm.
Press OFF to erase all the display of the cursor, trace, and measured data.
NOTE: If TRACE/AREA key is pressed in the middle of the measurement, the cursor and measured values will be cleared
(LED will go out). To complete a measurement, repeat the preceding procedure.
By repeating the preceding procedure, up to four measurements for circumference and area are possible on the same screen.

Five types of calculations are available.
Circumference (mm) Circumference is calculated by using the formula to approximate an ellipse circumference. It is necessary to make two distance measurements.
Volume (cm
3
) Volume is calculated by a formula corresponding to the number of measurements made. Volumes can be calculated using one, two or three measurements.
Heart Rate (per minute) Heart rate per minute is calculated by measuring the interval between two beats in M-Mode.
Velocity (mm/s) Velocity is calculated by using the amplitude measured in M-Mode.
A/B (ratio) Ratio is calculated by comparing two distance measurements.
NOTE: When you repeat any of the above CALC 1 calculations, you must press the OFF key first to clear the calculation register.
Failure to do so will cause the second calculation to use the first set of measurements.

Four Measurements If four measurements are made before the ENTER key is pressed (not normally done but possible with the RT 3200 Advantage - I), the last diameter is ignored and the system operates as for three diameters, using the first three measurements. If the system is unfrozen, all measurements will be lost.

6-4-3 Stepper Volume
Stepper Volume (STVOL) is the method used to calculate the volume of an organ using the RT 3200 Advantage - I Urology software, a Transaxial
Probe, and a mechanical stepping device that moves the probe in fixed increments. The calculation is based on the fact that each step or area measurement is taken at equal stepper increments. The area measured at each slice is then used to compute the total volume of the organ. For more
Stepper Volume
Increment Selection
Before the stepper volume calculation can be made, ensure that the mechanical stepper increment used matches the ultrasound system stepper spacing selection.
CAUTION
Standard stepper increment movement is 5.0mm. The stepper can be reconfigured to move in 2.5mm increments. Therefore it is necessary to match the stepper movement to the ultrasound system software.
Failure to accurately match the mechanical stepper increment to the ultrasound system stepper spacing will result in improper volume calculations.

UROLOGY OPTIONS
This section provides information on additional urology capabilities. The
Stepper Volume calculation allows for area measurements to be taken at fixed increments. The mechanical stepping device is used to hold the probe in a fixed position; it moves at fixed intervals to ensure that each area measurement taken is equally spaced. The 7 MHz Transaxial (RA) Probe complements the mechanical stepper.

7-3-6 Use of RA Probe with Volume
Stepper Device
The 7 MHz Transaxial (RA) Probe is designed to be used with mechanical stepping device and needle placement guide shown in Illustration 7-2. The needle placement guide matches the electronic needle placement grid displayed on the RT 3200 Advantage - I. When used with the stepper volume calculation option, a "stack-of-coins" method can be used to calculate the volume of the prostate gland.
NOTE: This product is compatible only with needles of 20 cm in length and 16 to 20 gauge.
46-030370 REV 3 UROLOGY OPTIONS 7-5
7-3-6 Use of RA Probe with Volume
Stepper Device
(continued)
A typical exam consists of:
• Placing the patient in the supine position.
• Carefully inserting a properly prepared RA probe and orient it to scan the prostate at its most cephalic position.
• Position the mechanical stepping device and secure the RA probe to the stepper. If the needle placement guide is to be used in the exam, carefully align the probe to the needle placement guide registration line.
• Make as many stepper volume measurements as necessary to calculate the volume of the prostate.
• Retract the probe (utilizing the stepper device) the necessary step between each incremental slice of the gland.
• Once the complete gland has been evaluated detach the probe from the mechanical stepper and carefully remove it from the patient.
This calculated information can be used for future procedures, if necessary.

7-3-5 Typical Use
The stepping device is utilized to accurately calculate an organ's volume by stepping through the organ in 5mm increments. This is also available in
2.5mm increments. (Refer to Illustrations 7-14 and 7-15). The device is
most commonly used to calculate prostate volume for seed implant therapy.
Volume is used in the pre-planning for seed placement and also utilized during the surgical procedure to guide the user in the placement of the seeds.
Stepper/Probe Attachment
• Turn the advance/retract knob to place the stepper in its fully retracted position.
• Set the slide marker towards the rear of the stepper as a reference.
• Advance the stepper. (Use the slide marker as a reference. Each mark equals 5.0mm.)
• Place the stepper and mounting bar into the universal table mount clamp. Make a course adjustment to align it with the patient. Tighten the mounting bar locking knob and universal table mount locking knob.
• Gently insert the properly prepared 7.0 MHz transaxial probe into the patient. (Refer to the Transaxial Probe (RA) Operator Manual for probe preparation.)
• If needed, attach the needle placement guide template. Secure the needle placement guide to the transaxial probe.
• Be sure to align the probe center line with the mark on the needle
placement guide as shown in Illustration 7-17.
• Place the probe cradle clamp over the transaxial probe and partially tighten the clamp locking knob.

7-4 Stepper Volume
Calculation
7-4-1 Stepper Volume
Formula
Stepper Volume (STVOL) is the method used to calculate the volume of an organ using the RT 3200 Advantage - I Urology software, Transaxial Probe and a mechanical stepping device that moves the probe in fixed increments.
The calculation is based on the fact that each step or area measurement is taken at equal stepper increments. The area measured at each slice is then used to compute the total volume of the organ, according to the following model:
For N slices, there are N-1 volumes between the slices plus a small volume at each end.
It is assumed that the small volumes of the end caps are cones with a base equal to the measured area of the end slice and height equal to the slice spacing. The cones will have volumes V=A
1
d/3 and V=A
N
d/3 for slices 1 and
N respectively, where d is the spacing between the slices.
The volumes between the slices are assumed to be segments of a paraboloid of revolution, where the volume between any slice n and n+1 is
(A n
+A n+1
)d/2.
The sum of the volumes between slices is:
V=d

[ ( )

7-4-2 Basic Principles of Operation
The stepper volume measurement works ONLY in B-Mode. Stepper volumes are not accumulated in either B/M- or M-Mode. Stepper Volume will only be functional with the RA Probe attached.
A stepper volume measurement begins when the first area measurement is made while the system is in the CALC 2, Menu Level 3 STVOL (stepper volume) function.
The volume measurement ends when the ENTER key is pressed while at
CALC 2, Menu Level 3 (STVOL). If ENTER is pressed while in B/M- or
M-Mode, the keystroke is ignored and the system emits a beep.
During the measurement operation, pressing the ENTER key resets the internal memory to enable a new volume measurement to begin and displays the completed volume on the lower left side of the image display under the last accumulated volume calculation.
The CONTROL, T function changes the step increment or reselects the present step increment which will cause the current volume and slice number to be cleared. The next area measurement will then be interpreted as the first slice of a new volume.
The OFF key is used to reject a slice area measurement. When the OFF key is pressed:
• The measurement graphics are erased.
• The slice #, area and volume in the scrolling area (lower left portion of the display) remain the same.
• The current slice number and area are reset, but all previous measurements are retained.
• The rejected slice data remains on the screen. It will be scrolled up when the slice measurement is repeated.
The measurement can now be repeated on the frozen image or unfreeze and change the parameters. Refreeze the image and repeat the slice measurement on the new image.
After the measurement has been repeated, the old data will be scrolled up and the same slice # with the new data will be displayed in the scrolling area.
If OFF is pressed followed by ENTER, the volume is equal to the accumulated volume of the last accepted slice.
Once the image is unfrozen, the slice area is calculated from the measurement and a new measurement for that increment (slice) can NOT be made.
UROLOGY OPTIONS 46-030370 REV 0
7-4-2 Basic Principles of Operation
(continued)
Table 7-1
Measurement Parameter Resets
Unfreezing the image after a measurement has been made, without pressing OFF, is a sign that the measurement has been accepted. The system calculates the slice area and advances to the next slice for a measurement.
The last four (4) lines of this scrolling area of the image display will then read:
# 1 = XX.X
VOL XXXX
# 2 = XX.X
VOL XXXX
Slice # & Area
Accumulative Volume
Slice # & Area
Accumulative Volume
The volume is in cubic centimeters and includes a decimal point, as displayed for the current CALC 1 VOL calculation.
The internal parameters relevant to the stepper volume measurement are at three levels: the current slice number/area measurement, the last slice number/area/volume, and the volume data displayed on the left side of the image monitor. These parameters are reset as outlined in Table 7-1.

CAUTION
Before the stepper volume calculation can be made, ensure that the mechanical stepper increment used matches the ultrasound system stepper spacing selection.
Standard stepper increment movement is 5.0mm. The stepper can be reconfigured to move in 2.5mm increments. Therefore it is necessary to match the stepper movement to the ultrasound system software.
Failure to accurately match the mechanical stepper increment to the ultrasound system stepper spacing will result in improper volume calculations.

NOTE: Each time SET is pressed, the cursors become alternately active. Adjustments to the ellipse may be made as desired.
The highlighted cursor is the active cursor.
When satisfied with the ellipse, press the MEAS key to record the first area measurement.
After the MEAS key is pressed, the area is calculated and displayed on the lower left side of the display in the following format:
#XX = XX.X

This represents the slice number that was just measured, the area of that slice in square centimeters and the accumulative volume in cubic centimeters.
NOTE: If the image or the area measurement for this slice are unacceptable, press OFF now. The slice measurement can be repeated.
Unfreezing an image, without pressing OFF after the second diameter measurement has been locked in by pressing MEAS, permanently records the slice area and advances the slice number. It is not possible to go back and redo a previous slice measurement without restarting the entire stepper volume sequence.
Unfreeze the image. Move the mechanical stepper to the next increment.
Repeat the ellipse area measurement steps for each necessary slice.

A-1 Control Parameters
APPENDIX A
CONTROL PARAMETERS
The transmit acoustic power and intensity output of the imaging system is related to various control settings which you can change during the course of an exam. You should be aware of which controls affect output so you can obtain the optimal image, while at the same time exposing the patient to only minimum ultrasound energy.
A-2 Control Parameters
Which Affect Acoustic
Sound
Focus
Changing the focus to optimize the image over a particular region of the scan changes the depth at which the maximum intensities may occur. Typically, the region of maximum intensity is close to the focal distance. Values reported in Table A-1 represent the maximum intensity at one particular focal depth. All other focus depths result in lower values.
M-Mode
The following parameters can affect acoustic output.
Placing the machine into M-Mode affects the acoustic output of the system.
In M-Mode, repetitive pulse firings occur on the same scan line (corresponding to the M-Mode vector displayed) which increases the time-average of
SPTA intensity along the scan line chosen. The SPTA intensity is typically increased by a factor of 30 to 60 times over that in B-Mode. In almost all cases, the total output power and the pulse average intensities (i.e., SPPA or Im) are not affected, even along the scan line chosen.
B/M-Mode
In this combination mode, both B- and M-Mode vectors are generated by the machine. The SPTA intensity will be increased along the M-Mode line selected, but typically not to the extent as when M-Mode alone is selected.
As with M-Mode, the SPPA, I-m and total power remain unchanged.
The SPPA and I-m intensities remain relatively constant, regardless of mode selected. The SPPA intensity is strongly affected by mode selection, as a result of more pulses being directed at the specific site selected. The SPTA intensity
is increased in M-Mode over B-Mode as shown in Table A-1.

ACOUSTIC LEVEL NOTES
1.
System Acoustic Power Control set at 100%, with system parameters adjusted to maximize individual intensities.
2.
Intensities and focal areas measured in water at locations which correspond to maximized normalized (in-situ) intensities.
3.
The water values can be converted to normalized (in-situ) values by using the following formula:
I t
= I w e-
0.23a´fz where:
I t
= in-situ intensity
I w
= measured water intensity e = appx. 2.7183
a´ = tissue attenuation (0.3dB/MHz/cm) f = Ultrasonic center frequency (MHz) z = ultrasound path length (one-way)(cm)
4.
In-situ intensity values remain below FDA specified pre-enactment values for applicable clinic applications for all control settings.
5.
20dB Beam Area represents the 2-dB two-way beam area of a single vector measured at the depth of maximum SPTA intensity.
6.
Beam Entrance Area represents the area at the surface of the transducer emitting one acoustic vector. For sector scanners, this is also the active acoustic area in contact with the patient.
B-2 Measurement Basis for
Probe Output
Acoustic Power (milliwatts)
Probe acoustic power output is determined by measuring the force exerted on an absorbing target by the acoustic radiation field with a force microbalance.
Acoustic Intensity
(milliwatts/cm
2 or watts/cm
2
)
Probe acoustic intensity levels are determined using a calibrated
(milliwatts/cm2 or watts/cm 2 ) PVDF miniature hydrophone.

C-1 Overview
C-2 Probe Cleaning
WARNING
APPENDIX C
CLEANING AND INSPECTING
This section explains how to clean and disinfect the probes and how to clean the console, monitor, video cassette recorder, printer and multi imaging device surfaces. It also provides a checklist for monthly system inspections.
Before cleaning the probes, refer to the caution, cleaning and disinfection instructions in the probe box.
• After each use, disconnect the probe from the ultrasound console and remove coupling gel from the transducer by wiping with a soft cloth and rinse with flowing water.
• Wash the probe surface with mild soap in lukewarm water. Scrub the probe as needed using a soft sponge, gauze or cloth to remove all visible residue from the probe surface Prolonged soaking or scrubbing with a soft bristle brush (such as a toothbrush) may be necessary if material has dried onto the probe surface.
• Rinse the probe with enough clean, potable water to remove all visible soap residue.
• Air dry or dry with a soft cloth.
Special Cleaning Instructions for the MZ probe: When cleaning the MZ probe, it is important to be sure that all surfaces are thoroughly cleaned. This probe has an adjustable two-part handle that must be disassembled to gain access to all surfaces. To disassemble the handle, completely remove the handle adjustment screw located mid-way between the cable entry and probe tip. The two handle halves and adjustment screw must be thoroughly cleaned along with the main probe shaft as described earlier. After rinsing and drying is completed, the probe handle can be loosely reassembled for the disinfection process.
Ultrasound transducers can easily be damaged by improper handling.
Failure to follow these precautions can result in serious injury and equipment damage.
• Do not immerse the probe into any liquid beyond the level indicated by the immersion level diagram in Illustration C-1.
• Never immerse the transducer connector or probe adapters into any liquid.
• Avoid mechanical shock or impact to the transducer.
46-030370
2
CLEANING AND INSPECTING C-1
C-2 Probe Cleaning (cont'd)
• Transducer damage can result from contact with inappropriate coupling or cleaning agents.
¤ Do not soak or saturate transducers with solutions containing alcohol, bleach or hydrogen peroxide.
¤ Avoid contact with solutions or coupling gels containing mineral oil or lanolin.
¤ Avoid temperatures above 60
°
C.
• Inspect the transducer prior to each use for damage or degradation to the housing, cable, strain relief, lens and seal.
• Do not use a damaged or defective transducer.
C-3 Disinfection
Perform the cleaning instructions in Section C-2 before following the disinfection procedures.
• Properly immerse the probe in a suitable commercial germicide. Use an
EPA registered germicide intended for use on plastic medical instruments. Follow the germicide manufacturer's instructions regarding concentration, time of contact, storage and disposal.
• 2% Glutaraldehyde type solutions without surfactants are recommended.
Cidex is the only germicide that has been tested to be safe and compatible with the materials used in the construction of the probes.
• Follow the germicide manufacturer's instructions for rinsing after removal from the germicide.
Special Disinfecting Instructions for the MZ Probe: After proper cleaning, to properly disinfect the MZ probe, the probe handle can be reassembled loosely so that the entire probe with handle can be immersed in the germicide solution. The adjustment screw must be kept loose so that germicide can penetrate to all surfaces. After immersing, rotate and shake the probe while it is below the surface of the germicide to eliminate air pockets. Allow the germicide to remain in contact with the fully immersed probe, for high-level disinfection, according to the germicide manufacturer's recommended time. To remove all germicide residue, final rinsing should be done following the germicide's manufacturer's instructions. Remove excess water by shaking and allow to air dry.
C-2
CLEANING AND INSPECTING 46-030370 REV 2
C-4 Gas Sterilization
Perform the cleaning instructions in Section C-2 before following the gas sterilization procedures.
• If necessary, ethylene oxide or formalin gas sterilization process may be used on surgical and biopsy probes only.
• Follow the instructions, recommendations and precautions provided by the manufacturer of the sterilization equipment and gas supplier.
• To avoid probe damage, do not use process cycles that exceed 60
°
C or pressures that vary from normal atmosphere.
Adequate cleaning and disinfection is necessary to prevent disease transmission. Use probe sheaths whenever possible. It is the responsibility of the equipment user to verify and maintain the effectiveness of the infection control procedures in use.

Hip Dysplasia Calculation
The HIP calculation is provided to assist in assessing the development of the infant hip. In this calculation three straight lines are superimposed on the image and aligned with the anatomical features. The two angles are computed, displayed and can be used by the physician in making a diagnosis.
The three lines are:
1. The Baseline connects the osseous acetabulum convexity to the point where the joint capsule and the perichondrium unite with the disc bone.
2. The inclination line connects the osseous convexity to the labrum acetabulare.
3. The Acetabulum roof line connects the lower edge of the osileum to the osseous convexity.

#1 Estimated Fetal Body
Weight (AC/BPD)
The Estimated Fetal Body Weight #1, is computed using a Shepard/
Richards/Berkowitz model. An evaluation of two equations for predicting weight by ultrasound. (Shepard et al., Am. J. Obstet. Gynecol., 142:47-54,
1982).
EFBW is determined according to the equation:
LOG
10
(EFBW) = 3 - 1.7492 + 0.0166*BPD + 0.0046*AC -
0.00002646*AC*BPD
The above formula yields EFBW in kilograms when the AC and BPD are in centimeters. (The machine automatically makes the conversion from kilograms to grams and millimeters to centimeters.) (For OB TBL 1 only)
When EFBW is selected, this calculation is made only if AC and BPD measurements have already been made. Otherwise, the EFBW (BPD, AC) field to the left on the screen will display U.F. and will be blank in the report page.
#2 Estimated Fetal Body
Weight (FL/AC)
The Estimated Fetal Body Weight #2 (EFBW) is computed using the
Hadlock Model. (Hadlock, F.B., et al,:
Sonographic Estimation of Fetal
Weight, Radiology, 150:535-40, 1984.)
EFBW is determined according to the equation:
LOG
10
(EFBW) = 1.3598 + 0.01844*FL + 0.0051*AC - 0.000037*AC*FL
The above formula yields EFBW in grams when the AC and FL are in millimeters. (The machine automatically makes the conversion from kilograms to grams and millimeters to centimeters.) (For use with OB Table 1 gestational ages only.)
When EFBW is selected, this calculation is made only if AC and FL measurements have already been made. Otherwise, the EFBW (FL, AC) field to the left on the screen will display U.F. and will be blank on the report page.

The above formula yield EFBW in grams when the FL, AC, and HC measurements are in millimeters. (The machine automatically makes the conversion from kilograms to grams and millimeters to centimeters) (For OB
TBL 1 only).
When EFBW is selected, this calculation is made only if the FL, AC, and HC measurement have been made. Otherwise, the EFBW #3 field to the left on the screen will display U.F. and will be blank on the Report Page.
NOTE: If BPD, FL and AC measurements have already been made, then both EFBW (BPD,AC) and EFBW (FL,AC) values will be displayed to the left on the screen and in the report page.
Calculations are made from the last measurement entered or averaged.
Heart Rate
This is the fetal heart rate, in beats per minute, computed in the CALC 1 function, menu level 3. If this measurement is not made, the field is blank.
Amniotic Fluid Index
The Amniotic Fluid Index is determined by taking a distance measurement of the amniotic fluid depth in each of four axial quadrants. These four measurements are added together to formulate the Amniotic Fluid Index (AFI).
Normal values are considered to be:

Error Markers
Whenever three or more gestational age measurements are included in the
CGA (the arithmetic mean of the included gestational ages), an arrow may appear on the report page to mark the GA which is farthest from the CGA.
This arrow is immediately to the right of the gestational age. This makes it easy to spot the outlying measurement. If there is a tie between two or more
GAs for the outlying measurement, no arrow will appear. When a hardcopy print of the screen is made using the RECORD key, the error marker arrow is temporarily erased and does not appear on the print.

Page
The RT 3200 Advantage - III video printer generates hardcopy prints. To print the report, press the RECORD key when the report page is on display.
When you press RECORD, the system modifies the displayed report page before starting the recording process. First, it erases the gestational age error marker (the arrow which may appear to the right of a gestational age).
Then, it draws solid white areas at the bottom of the report page. These bars provide white space on the hardcopy print for your signature and date. After the exposure, the system erases the bars and restores and GA error marker.
When your RT 3200 Advantage - III is connected to an IBM (or compatible) computer via the RS-232 Serial Port, and the Report Page is displayed, the
RECORD key will transmit the measurement data on the Report Page to the computer. When you press RECORD, the data is transmitted and an
Acknowledge will display in the Reported By area to confirm the transmission of data has been received by the computer.

(continued)
If you selected menu level 4 (AC), the transverse diameter is stored as the
TAD, and the anterior-posterior diameter is stored as the APD, both of which are shown on the report page.
If you selected menu level 5 (HC), the system uses the anterior-posterior diameter to compute cephalic index. BPD is not shown on the report page unless you enter a separate BPD estimation. The occipito-frontal diameter is stored as the OFD, which is shown on the report page and used in the computation of the cephalic index.
NOTE: The OB TBL 1 or OB TBL 2 function identifies and stores the diameter and circumference data as pertaining to either the head or abdomen.
There are three possible sources for the circumference data used to estimate gestational age by HC or AC. The first is a circumference by using the TRACE/AREA function. The second is a circumference by computing two diameters. The third is the ellipse measurement.

If the AVERAGE ALL field is "N" (no), then the default for the current measurement is "Y" (yes) and the two prior measurements will be "N" (no).
"No" is the factory and service default setting for the AVERAGE ALL field.
If the measurement Averaging Page is never used, the AVERAGE ALL selection is likely to be "N" (no).
If the AVERAGE ALL field is set to "Y" (yes), the default for all measurement fields will be "Y" (yes). It is assumed that all measurements (up to three) will be averaged as a matter of regular procedure.

10-9-6 No Code
Comment text from the library can be inserted on to the ultrasound image display as well as in the comment field of the OB Report Page, Urology
Report Page, Anatomical Summary Page, GYN Report Page and IVF
Report Page.
To place comments in the Report page, you must display that report page and move the cursor down to the appropriate spot in the comment field.
To place comments on the ultrasound image, press the COMMENT key while in the comment mode.
Once you have moved the cursor to the appropriate spot in the image or report page, type in the code word (maximum four characters). Press
ENTER. The comments library will be searched for the code word. If the code word is found, the code is overwritten by the text string on the image or report page. The text will wrap at the right margin, just as if you had entered it from the keyboard.
NOTE: If you are using more than one pre-programmed comment consecutively, be sure to place a space between each comment selection.
Code characters must be entered by the keyboard. Preexisting characters or text will not be appended to keyboard input to form a code.
Example: Suppose the comment field contains the text
"PQRSTUVWXYZ". The user positions the cursor after the "Z" and enters "AB" and presses ENTER. The system will search the library for the code "AB", not "YZAB". If the code "AB" is found, only the "AB" will be replaced with text from the library.
If no code is found in the comment library, the system will react in two different ways.
If you are in the Comment Mode the system assumes that the characters preceding the ENTER were normal text. It assumes the user pressed
ENTER in order to exit the Comment Mode and make the keyboard entries permanent. Thus an exit will be performed.
If you are in the comment field of a Report Page, the code search failure is recognized as an error. The system will beep and the code entered remains on the comment field.

REPORTED BY: REPORT DATE:
The Urology Report Page contains patient data information, measurement results of three volumes, specific exam comments, lesion site comments and general comments.
The Patient Name and ID can not be edited on this report page. They were entered prior to the start of the exam by using the ID/NAME key.
There are three fields in which measured volumes are reported. These volumes are obtained from the volume measurements taken in the CALC
1 and/or CALC 2 menus. The first volume measurement taken is recorded as Volume #1. The second and third measurements are recorded as
Volume #2 and Volume #3, respectively.
The system will store the three most recent volume measurements. If a fourth volume measurement is made, Volume #1 is erased. Volume #2 becomes #1. Volume #3 becomes #2 and the forth measurement is Volume
#3. The very first measurement is lost.
In the space to the right of each volume measurement, the user can type in comments pertinent to that particular volume measurement.
NOTE: If the volume measurements were taken in the CALC 2 STVOL
(stepper volume) selection, the word "STEPPER" will appear in the comment line to the right of the volume measurement.

10-14 Cine Memory Operation
(OPTION)
10-14-1 Overview
Cine Memory is an option to the RT 3200 Advantage-I Version 5 software system. Cine Memory is free running storage of 32 image frames in B-Mode operation only. Free running means that during B-Mode operation only, the system displays the current image and has in memory the 32 previous image frames.
The 32 images represent approximately two seconds of scan time. The operator essentially has two seconds added to the response time needed to freeze an image. The obvious advantage being that the operator can freeze the image and recall a previous image from memory. If the patient moved or breathed just as the image was frozen, an image prior to movement can be recalled for taking measurements, recording or printing.
The only functional difference between a system with or without the Cine
Memory option is apparent after an image is frozen and the GAIN control knob is rotated.
10-14-2 Single Image
Operation
Cine Memory functions in B-Mode only. When FREEZE is activated, the image is displayed on the monitor as before, with the following exceptions:
• Gain, Dynamic Range and Focal Zone numbers are no longer displayed after the GAIN control knob is rotated for Cine Memory review.
• The Cine Memory position indicator replaces Gain, Dynamic Range and
Focal Zone after the GAIN control knob is rotated.

10-14-2 Single Image
Operation
(continued)
The arrow on the position indicator will always be on the far right side initially.
This is the most current image.
Turning the GAIN control knob counterclockwise allows for the review of any of the previously stored 32 image frames. The arrow pointer moves with every "click" of the GAIN control knob to show the relative position of the image in Cine Memory.
Rotating the GAIN control knob clockwise reviews images in the opposite direction. Once a left or right limit is reached, the review wraps around to the opposite end and continues displaying images from Cine Memory with
GAIN control knob rotation.
After choosing the desired image, the operator can make measurements and have them entered on a report page. Annotations can also be added or pictures taken on the thermal printer or multi-image camera.
If the GAIN control knob is rotated, the measurement cursors will be erased.
They are not stored with the image. It is not possible to rotate back and have the measurement cursors reappear.
Measurements displayed on the left side of the display will remain when the
GAIN control knob is rotated. Press the OFF key to remove this measurement data from the display.
Annotations are also separate from measurement cursors. Annotations will remain when the GAIN control knob is rotated. Press the ERASE key to remove annotations.
10-14-3 Multiple Image
Operation
Multiple Image operation functions like single image Cine Memory. Cine images are available for the last side (right or left) frozen. The Cine position indicator, measurements and annotations work as previously explained.
Cine Memory is not available for both sides (right and left) simultaneously.
It is only available for the side showing the Cine position indicator. When switching sides, the Cine Memory function switches to the active side.
