Image Optimization 5-9
5. Adjust the image parameters to obtain optimized images.
6. Perform other operations (e.g. measurement and calculation) if necessary.
5.5.2 M Mode Parameters
In M mode scanning, the image parameter area in the upper left corner of the screen
displays the real-time parameter values as follows:
Display V 3 IP 6 DR 65 G 45
During M mode imaging, you can switch between B and M menu from the menu title.
During M Mode scanning, frequency and acoustic power of the transducer are
synchronous with that of B Mode.
Adjustment of the depth or TGC to the B Mode image will lead to corresponding changes
in M Mode image.
5.5.3 M Mode Image Optimization
Gain
To adjust the gain of M mode image. The real-time gain value is displayed in the
image parameter area in the upper left corner of the screen.
Rotate the <Gain/ iTouch> knob clockwise to increase the gain, and anti-
clockwise to decrease.
The adjusting range is 0-100.
Increasing the gain will brighten the image and you can see more received
signals. However, noise may also be increased.
Depth
This function is used to adjust the display depth of sampling, the real-time
value of which is displayed on the image parameter area in the upper left
corner of the screen.
Use the <Depth/Zoom> knob to adjust the depth.
The adjustable depth values vary depending upon the probe types.
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.
Frequency
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.
