Adjusting Time Gain Compensation (TGC)
Adjust the gain which compensates for the attenuation (a reduction in sound amplitude) of the echo signals
in proportion to their depth (based on travel time)
Touch TGC to display the TGC sliders on the screen To increase/decrease the gain at the desired section
(depth) of the image, drag the corresponding slider to the right/left
Adjusting the Scan Depth
Adjust the field of view To view larger or deeper structures, increase the depth To enlarge the display of
structures near the skin line, decrease the depth The system automatically adjusts the frame rate (FPS) and
acoustic power indices (TI/MI) based on the scan depth
Touch Depth +/- or flick horizontally on the scan area to set the scan depth
Adjusting the Focus Depth, Focal Zone and Focal span
Focus optimizes the image by increasing the resolution for a specific area and is displayed by a red arrow
marker indicated at the depth ruler Depending on the transducer in use and the mode selected, multiple
focus depths can be added Increasing the number of focal zones decreases the frame rate If the frame
rate is not high enough, try decreasing the number of focal zones
Touch Focus +/- to adjust the depth value Touch Focal Zone +/- to select the desired number of focal
zones Touch Focal Span +/- to adjust the distance between the focal zones
Adjusting Dynamic Range
Control the range of acoustic levels displayed in the image, which affects the contrast of the image
Touch Dyn Range +/- to adjust the amount of compression
Using Tissue Harmonic Imaging (THI)
Reduce superficial artifact and provide better gray scale contract by processing an integer multiple of the
fundamental frequency, a harmonic wave
Touch THI to enable this function
Adjusting Persistence
Adjust the amount of frame averaging from real-time images or loops Higher persistence produces less
speckled and smoother image but reduces the temporal resolution
Touch Persist +/- to adjust the value
Adjusting Sharpness and Smoothing
Improve the sharpness of the image by enhancing the edge contrast and smoothening the tissue speckle
Touch XRES +/- to adjust the value
Adjusting Gray Map
Change how the amplitude is converted to brightness
Touch Gray Map +/- to adjust the value
