5. Visually evaluate the result using the installed imaging
software.
Subjects to be evaluated:
1. Smoothness of the exposed area. Non-exposed area
surrounds the whole image.
2. High contrast resolution; minimum 3.1LP/mm must be
distinguishable.
3. All four low contrast holes must be visible.
4. Roundness of the ball.
5. The ball should be placed symmetrically between the two
pins. The distance from both pins to center should be
equal length.
Re-do panoramic geometry calibration if above conditions
are not met.
NOTICE! The panoramic QC collimator is equipped with a
0.8 mm copper filter. If more filtration is required, additional
filtration may be attached to the tubehead cover. The unit
may be configured to use higher exposure values to
compensate for an additional 1 mm copper filter using
service command copperthickness. Refer to service
command help copperthickness for further instructions.
