8.4.4 Penetration
To test penetration:
1. Adjust the system controls to obtain a clear image that shows the limits of echo
penetration as shown in Table 8.2.
2. Measure from the center of the skinline to the deepest vertical position—where
the scatter echoes start to break up and tissue definition is lost.

8.5.1 CPD
To test CPD:
Note: Use the RMI 425 Doppler Phantom or the RMI 1425A Doppler Phantom.
4.
Connect any transducer and set up the system for CPD mode.
2. Acquire the image.
To adjust CPD gain:
* Turn gain clockwise to increase the amount of CPD gain.
(While in CPD
imaging, near and far affect only the 2D image; they do not
affect the CPD
image.)
+ Turn gain counterclockwise to decrease the amount of
CPD gain.
