8.5.2 PowerMap DCPD
To test PowerMap DCPD:
Note: Use the RMI 425 Doppler Phantom or the RMI 1425A Doppler Phantom.
1. Set up the system per section 8.5.1 for CPD mode.
2.
Press the 8 key while in CPD mode for PowerMap DCPD . A Region of Interest
(ROI) box is displayed on top of the 2D grayscale. (Press the 0 key to return to
2D imaging.)
To move the PowerMap DCPD image:
• Use the trackball to move the PowerMap DCPD ROI. While you are moving
the PowerMap DCPD ROI, you will see an outline of the new position
moving on the display. When you stop moving, the new position will display
the PowerMap DCPD ROI. (The size of the PowerMap DCPD image is fixed.
There is no control to change it.)
To adjust PowerMap DCPD gain:
• Turn gain clockwise to increase the amount of PowerMap DCPD gain.
(While in PowerMap DCPD imaging, near and far affect only the 2D image;
they do not affect the PowerMap DCPD image.)
• Turn gain counterclockwise to decrease the amount of PowerMap DCPD
gain.
3. Image the 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.
4.
Save a PowerMap DCPD image by pressing Freeze and then Save .
8.5.3 M-mode Imaging
1. Attach a C60 transducer and acquire an image.
2. Press the 9 key for the M-mode sample line.
3. Position the M-mode sample line over the image by moving the trackball left
or right.
4. Press the 9 key again to turn on M-mode .
5. Adjust the sweep speed by pressing the Menu key and pressing the sweep speed
key from the on-screen menu.
6. Press the Freeze key to freeze the image. Press it again to return to live imaging.
7. Press the 0 key again to return to 2D imaging.
