Mindray M7T - Power Mode Image Optimization

5-20 Image Optimization
Operation Press <iTouch> on the control panel to turn on the function, the symbol of
which will be displayed in the image parameter area of the screen.
5.6 Power Mode Image Optimization
Power mode provides a non-directionally display of blood flow in the form of intensity as
opposed to flow velocity.
DirPower (Directional Power Mode) provides the additional information of flow direction
towards or away from the probe.
5.6.1 Power Mode Exam Protocol
1. Select a high-quality image during B mode or B+ Color scanning, and adjust to place
the area of interest in the center of the image.
2. Press <Power> to enter B+Power mode. Use the trackball and <Set> to change
position and size of the Region of Interest (ROI).
3. Adjust the image parameters to obtain optimized images.
4. Perform other operations (e.g. measurement and calculation) if necessary.
5.6.2 Power Mode Image Parameters
