Typical B-Mode Exam Protocol
A typical examination using B-Mode might proceed
1. Record exam-related patient information. Verify system setup (probes and presets).
2. Position the patient and the console for optimum operator and patient comfort. Perform the scan.
3. Complete the study by collecting all the data.
CAUTION
Ensure that the hands of the patient are away from the system during the exam.
The position of the operator and the patient vary by scan region.
In most case, the operator sits/stands straight in front of the operator console and the patient lies on the bed on the right (or left) side of the system.
CAUTION
Always use the minimum power required to obtain acceptable images in accordance with applicable guidelines and policies.

Gain
Description
Adjusting
Preset
Values
B-Mode Gain increases or decreases the amount of echo information displayed in an image. It may have the effect of brightening or darkening the image if sufficient echo information is generated.
To decrease/increase, rotate Gain.
Gain values vary depending on the probe; they are not associated with a particular position of the knob.
NOTE: B-Mode gain is independent of M-Mode and Doppler and Color
Flow Gain. Changing the M-Mode Gain while in M-Mode does not affect the B-Mode image gain.
You can set gain by probe and application on the Utility -->
Imaging page.
Gain displays on the monitor in Gn. Maximum gain varies by probe. Gain values vary by probe, application, and frequency setting.
NOTE: Maximum gain is factory preset to an optimum setting to eliminate noise in the display.
Benefits
Gain values are returned to the factory or user preset value when you change the following: Probe, Exam Category/Exam
Calc, or Patient.
Gain allows you to balance echo contrast so that cystic structures appear echo-free and reflecting tissue fills in.
Affect on other controls
Bioeffects
After you adjust the Power Output, you may need to adjust the gain. Generally speaking, if you increase the Power Output, you need to decrease the gain; if you decrease the Power Output, you need to increase the gain. Gain and TGC interact by adding together.
Gain has no affect on Power Output. However, with increased gain, the power output level can usually be reduced to produce an equivalent image quality.
NOTE: Always optimize gain before increasing the Power Output.

SRI-HD (High Detection Speckle Reduction Imaging)
Description
SRI-HD (High Detection Speckle Reduction Imaging) is an adaptive algorithm to reduce the unwanted effects of speckle in the ultrasound image. Image speckle usually appears as a grainy texture in otherwise uniform areas of tissue. Its appearance is related to image system characteristics, rather than tissue characteristics, so that changes in system settings, such as probe type, frequency, depth, and others, can change the appearance of the speckle. Too much speckle can impair image quality and make it difficult to see the desired detail in the image. Likewise, too much filtering of speckle can mask or obscure desired image detail. Extra care must be taken to select the optimal SRI-HD level.
SRI-HD is available in B-Mode imaging and may be used with any transducer or clinical application when image speckle appears to interfere with the desired image detail.

Values
Benefits
We recommend that you select the SRI-HD level by observing the enhanced image in side-by-side dual image comparison with the original, unprocessed image. Dual display mode is activated by pressing the L and R keys simultaneously.
In selecting the level of SRI-HD, you must observe the effects of
SRI-HD in the desired region of interest and should make a real-time comparison with the original image. The optimal level depends on the clinical situation and improves with experience.
Observing the original and SRI-HD-processed images together helps to determine whether too much or too little SRI-HD has been applied.
Dual image mode for SRI-HD can also be activated on a stored
CINE Loop. This allows you to always see the original, unprocessed or enhanced image by going into the Dual display mode and to change the SRI-HD settings when reviewing the
CINE Loop.
SRI-HD is available on 3D.
• You cannot change SRI-HD after the scan starts.
• The effects for the rendered image are less than the
2D-image.

LOGIQ View (Option)
Description
LOGIQ View provides the ability to construct and view a static
2D image which is wider than the field of view of a given transducer. This feature allows viewing and measurements of anatomy that is larger than what would fit in a single image.
Examples include scanning of vascular structures and connective tissues in the arms and legs.
LOGIQ View constructs the extended image from individual image frames as the operator slides the transducer along the surface of the skin in the direction of the scan plane. The quality of the resulting image is somewhat user-dependent and requires some additional skill and practice to develop proper technique and become fully proficient.
LOGIQ View is not available for the following:
• Color Flow Mode
Benefits
Clinical Use
Using LOGIQ View
The user can look at a larger region of interest within one field of view that is wider than any given probe would normally provide.
LOGIQ View is intended for scanning areas too large to fit on one image.
To perform an exam using LOGIQ View,
1. Perform a detailed examination of the anatomy/pathology.
Optimize parameters for tissue texture and visible window
PRIOR TO activating LOGIQ View.
2. Press the user defined key for LOGIQ View.
3. To start acquiring the image, press L key.
HINTS
When you scan, scan slowly and in a uniform motion lengthwise, end-to-end (with or against the probe orientation marker). LOGIQ View acquires images via leading edge vectors (and does not acquire slices, as in CINE). The image is being stored as you perform the scan and you can watch the
LOGIQ View as it is being acquired.

5. To complete the scan, press R or Freeze (or allow the scan to auto complete). The LOGIQ View is then displayed, scaled to fit entirely on the screen.
6. Perform measurements and record images.
The quality and usefulness of LOGIQ View images is affected by transducer motion. Incorrect technique can contribute to image distortion.
Guidance and precautions for uniform motion:
• Continuous contact is required throughout the length of the extended image. DO NOT lift the transducer from the skin surface.
• Always keep the transducer perpendicular to the skin surface. DO NOT rock the transducer.
• Keep the motion within the same scan plane, if possible. DO
NOT slide the transducer laterally.
• Lateral turning (change in direction to follow anatomical structure) can be accommodated with slower motion. DO
NOT make abrupt changes in direction.
• The system accommodates a reasonable range of motion velocity. DO NOT make abrupt changes in speed of motion.
Deeper scans generally require reduced speed.
Activating LOGIQ View has no affect upon Acoustic Output values.
