Procedure
7. Click Continue.
8. When prompted, click OK to accept auto-
mated motions.
The detectors are automatically positioned for
intrinsic uniformity calibration of the selected
detector.
9. Place the point source in the source holder
and position the source holder at a dis-
tance of approximately 1.85 m (6ft.) from
the surface of the detector.
Note. If the CardioMD AC option is mounted
on the system, the special AC option point
source holder must be used. See Chapter 12
CardioMD AC Option for details.
10. Ensure that the point source is centered
relative to the detector field of view.
Check the position of the activity in the
image window on the acquisition PC. By
pressing [F9], you activate the center cross
hair in the image window. You may find
this useful for positioning the source
holder.
11. Remove the collimator from the selected
detector and mount the FOV mask instead.
12. Loosen and slide out the collimator on the
other detector a little.
Note. It is necessary to loosen the collimator
on the other detector in order for the Car-
dioMD system to detect the collimator type
NONE.
13. Verify that the count rate is less than 40
kc/s.
14. Click Start to start the uniformity calibra-
tion of the selected detector.
When the calibration is complete, the table is
automatically stored.
