3. Adjust color flow ROI.
−
Move the trackball to position color flow ROI.
−
Press the confirm key on the control panel to adjust the size of color flow ROI.
−
Press the confirm key again to reposition color flow ROI.
4. Optimize the CFM-mode image. For details, refer to Section 6.3.4 Optimizing CFM/
PDI/TDI Mode Images.

2 PDI Mode
PDI (Power Doppler Imaging) is a color flow imaging technology which adds the flow
signal in the CFM-mode image. PDI uses the number and amplitude of red blood cells
going through in the flow to create the color-coded imaging. A flow with slow velocity
and small rate can be displayed in PDI. Therefore, a flow with a higher sensitivity can be
detected without overlaying any flows with high velocity.
The direction of flow, the flow velocity and flow properties cannot be reflected in the PDI-
Mode image.
Perform the following steps to acquire PDI-mode images:
1. Optimize a B-mode image.
2. Press the CFM key on the control panel, and then tap PDI on the touch screen to enter
the PDI mode.
