Image Optimization 5-5
Operation To change depth, press keys in the lower right corner of the control panel.
Press
key to decrease the depth; Press key to increase the
depth.
Or adjust it in the image parameter area.
The adjustable depth values vary depending upon the probe types.
Effects Increase the depth to see tissue in deeper locations, while decrease the
depth to see tissue in shallower locations.
Impacts Depth increase will cause a decrease in the frame rate.
TGC
Description The system compensates the signals from deeper tissue by segments to
optimize the image.
There are 8-segment TGC sliders on the control panel corresponding to
the areas in the image.
Operation To increase the gain compensation at an area of interest, move the TGC
slider to the right.
To decrease the gain compensation at the corresponding area of interest,
move the TGC slider to the left.
About 1.5s after the adjustment is finished, the TGC curve disappears.
Effects Adjust the signal gain for the certain image area to get a balanced image.
Frequency
Description This function is used to select the operating frequency of the current probe,
the real-time value of which is displayed in the image parameter area in the
upper left corner of the screen, where “F” represents B mode frequency,
and “FH” represents harmonic frequency.
Operation You can select a harmonic frequency or a B mode frequency.
Adjust the frequency value through the [Frequency] item in the soft menu
or menu, “H” indicates harmonic frequency.
Or adjust it in the image parameter area.
Values of frequency vary depending upon the probe types.
Select the frequency according to the detection depth and current tissue
characteristics.
Effects The higher the frequency the better the near field resolution but the worse
the force of penetration.
Harmonic imaging enhances near field resolution and reduces
low-frequency and large amplitude noise, so as to improve small parts
imaging.
Acoustic Power
Description Refers to the power of ultrasonic wave transmitted by the probe, the
real-time value of which is displayed in the image parameter area in the
upper left corner of the screen.
Operation Adjust through the [A. power] item in the soft menu or menu.
The adjusting range is 7%-100% in increments of 3%.
