Detector Calibration
Procedure
8. Position the COR point source holder with
the source at the middle of the table cradle
and center it relative to the detectors field
of view.
To keep the source in place during the acquisi-
tion, you can use a piece of adhesive tape to
secure the source to the table cradle.
9. Verify that that the count rate is approxi-
mately 5 – 10 kc/s.
10. Click Start to start the COR acquisition.
11. When prompted, click OK to accept auto-
mated motions
The system rotates 180° in 256 steps. After the
acquisition, the system automatically stores
the acquired COR corrections for the specific
collimator under the matching file name.
Note. If a correction table for the type of col-
limators already exists, the system automati-
cally overwrites the old table immediately
after the new correction table has been ac-
quired.
12. When the acquisition has been completed
successfully, click Exit to close the COR-
COR page.
