6.2.2 B-mode Image Parameters
In B Mode scan, the image parameter area on the right part of the screen will display the real-time
parameters:
Image Quality
Used for switching B/THI and adjusting the frequency. The real-time value of frequency is
displayed in the image parameter area, and if harmonic frequency is used, “F H” is displayed as
harmonic frequency value.
The system provides a THI function using harmonics of echoes to optimize the image. Harmonic
imaging enhances near field resolution and reduces low-frequency and large amplitude noise, so as
to improve Small Parts imaging.
Please select the frequency according to the detection depth and current tissue features.
Gain
To adjust the gain of the whole receiving information in B mode. The real-time gain value is
displayed in the image parameter area.
Depth
This function is used to adjust the display depth of sampling, the real-time value of which is
displayed in the image parameter area.
Depth increase will cause a decrease in the frame rate.
TGC
The system compensates the signals from deeper tissue by segments to optimize the image.
There are 8-segment TGC sliders on the touch screen corresponding to the areas in the image.
Adjust the signal gain for the certain image area to get a balanced image.
Acoustic Power (A.Power)
Refers to the power of ultrasonic wave transmitted by the probe, the real-time value of which is
displayed in the upper left corner of the screen.
