8.3 PDI Mode
PDI (Power Doppler Imaging) is a color flow imaging technology which adds the flow signal in the
Color mode image. PDI uses the number and amplitude of red blood cell going through in the flow to create
the color-coded imaging. The flow with slow velocity and small rate could be displayed in PDI. Therefore,
the flow with a higher sensitivity can be detected without overlaying any flows with high velocity.

8.3.1 Entering the PDI Mode
Steps for entering the PDI mode are as follows:
1.
Select the appropriate probe and exam type, and optimize the B mode image.
2.
Press the
PDI
key on the control panel to enter the PDI mode, as shown in Figure 8-3.
3.
Adjust the color ROI.
Move the trackball to adjust the position of the color ROI.
Press the
Set
key and move the trackball to adjust the size of the ROI, or press the
Set
key again to
adjust the position of ROI.
4.
Optimize the PDI mode image. For details, refer to Section 8.3.2 Optimizing the PDI Mode Image.
Press the
Save IP
key to save the parameter settings in the PDI mode as the default settings.
5.
Press the
PDI
key again to exit the PDI mode.
8.3.2 Optimizing the PDI Mode Image
Methods for optimizing the PDI mode image are as follows:
Method 1: Select the PDI mode parameter on the menu at the top left of the screen by using the trackball,
press the
Set
key to adjust it. Press the
Menu
key to display/hide this menu.
Method 2: Select the PDI mode parameter on the menu at the top left of the screen by using the
Select
knob,
press
Select
knob change state between “parameter item select state”and “parameter item adjust state”, rotate
the knob change parameter item for “parameter item select state”or paramter value for “parameter item
adjust state”. Press the
Menu
key to display/hide this menu.
The adjustments of parameters in the specific PDI mode are similar to the Color mode, refer to Section 8.2.2
Optimizing the Color Mode Image.
