CPD

To test CPD:
Note: Use the RMI 425 Doppler Phantom or the RMI 1425A Doppler Phantom.
1 Set up the system for CPD mode. Set iLook 15 exam type to ABD.
2 Acquire the image.
3 Press and release the menu key and use the directional controller to select
CPD mode. A Region of Interest (ROI) box is displayed on top of the grayscale
image. (Select off to return to 2D imaging.)
Note: iLook 15 exam type must be set to ABD.
To move the CPD image:
• Use the directional controller to move the CPD ROI. While you are
moving the CPD ROI, you will see an outline of the new position moving on
the display. When you stop moving, the new position will display the CPD
ROI. (The size of the CPD ROI is fixed. There is no control to change it.)
To adjust CPD gain:
• Press the directional controller to select gain. Use the directional
controller to increase or decrease the amount of CPD gain.
4 Image a vessel using a Doppler phantom. Verify that as the gain controls
increase and decrease, Doppler echo intensity increases and decreases to
correspond. Verify that no flow exists outside the vessel.
5 Save a CPD image by pressing Freeze and then Save.
