Distance Measurement Accuracy (QA Phantom):
Evaluate Distance Measurement Accuracy
: In the currently open QA Phantom scan, Zoom into
the Axial View’s line pairs and make a distance measurement, using the Distance Tool, from
one end of the line pair set to the other end of the line pair set. The distance should be between
41.0 - 42.5 mm.
Consistency/Uniformity (Water Phantom):
To evaluate consistency, we will image the Water Phantom. Water phantom image may vary
from what was delivered with your machine.
1. The water phantom should be filled all the way to the top with distilled water, allow a bit
of air space at the top to close the container.
