Configurable
Parameters • LiveGain: To balance echo contrast so that cystic structures appear echo-free and
reflecting tissue fills in.
• Frequency: This optimizes the probe’s wide band imaging capabilities at multiple
frequencies to image at greater depths.
• CrossXBeam: Improve contrast resolution with increased conspicuity of low
contrast lesions, better detection of calcifications, biopsy needle visualization,
and cystic boundary definition.
• Gray Map: Affects the presentation of B Mode information.
• Focus Pos: Focus optimizes the image by increasing the resolution for a specific
area.
• Reverse: Used for anatomical correctness.
• ATO Level: Select the Auto Tissue Optimize Level to pick a preference for the
contrast enhancement in the resulting image.
• Dynamic Range: It is useful for optimizing tissue texture for different anatomy.
• Compression: Suppress the noise in the image.
• Rejection: Allow for the elimination from the display of low level echoes caused by
noise.
• Frame Aver: Smooth the image.
• SRI HD: Smooth the image when image speckle interferes with the desired image
detail
• Edge Enhance: Make the image edge clearer/sharper.
• FOV: Adjust field of view
• AO: Adjust acoustic output
Note: The configurable parameters can be configured in Utility->Settings->ScanConfig.
