Mindray ME8 - Power Mode Image Parameters; M Mode; M Mode Image Scanning; M Mode Image Parameters

6 Image Acquisition
Operator’s Manual 6 - 7
1. Select a premium image during B mode or B+ Color scan, and adjust to place the area of
interest in the center of the image.
2. Press <P> to enter B+Power mode.
3. Use the trackball/trackpad and <Set> to change position and size of the Region of Interest
(ROI).
4. Adjust the image parameters during scan to obtain optimized images.
6.3.2 Power Mode Image Parameters
Because both are based on Doppler color imaging, the adjustments of Power mode are same with
these of Color mode’s. Hence, only the adjustments of Power mode are introduced.
Power Gain
Refers to the overall sensitivity to flow signals, and this function is used to adjust the gain in Power
mode. The real-time gain value is displayed in the image parameter area.
Color Map
This feature indicates the display effect of power image. The maps in Power mode image are
grouped into two categories: Power maps and Directional Power maps.
• The Power maps provide information of blood flow, which are highly sensitive to the low-
velocity flows.
• The Directional Power maps provide information of flow direction.
Dynamic Range
This function is to adjust the transformation of echo intensity into color signal.
Increasing dynamic range will lead to higher sensitivity to low-power signals, thus enhances the
range of signals to display.
6.4 M Mode
6.4.1 M Mode Image Scanning
Perform the following procedure:
1. Select a premium image during B mode or B+ Color scan, and adjust to place the area of
interest in the center of the image.
2. Press <M> on the control panel, and use the trackball/trackpad to adjust the sampling line.
3. Press <M> on the control panel again or <Update> to enter M mode, and then you can observe
the tissue motion along with anatomical images of B mode. During the scanning process, you
can also adjust the sampling line accordingly when necessary.
4. Adjust the image parameters to obtain optimized images.
6.4.2 M Mode Image Parameters
Gain
To adjust the gain of M mode image, the real-time gain value is displayed in the image parameter
area.
Increasing the gain will brighten the image and you can see more received signals. However, noise
may also be increased.
