Procedure
The ECor page appears.
7. Unless a major repair requires a calibra-
tion from scratch, select Update ECOR ta-
ble.
8. Select the appropriate isotope (either Tc-
99m or Co-57).
9. Select detector 1 or 2 to be calibrated.
Note. If updating ECor, either isotope can be
selected. The update is not dependent upon the
isotope used during the initial ECor calibra-
tions.
10. Click Continue.
11. Press and hold the hand controller Colli-
sion Override button for a minimum of 4
seconds before proceeding as follows:
12. While still pressing Collision Override,
click OK to accept automated motions
bringing the system into position for cali-
bration of the selected detector.
Note. The hand controller Collision Override
button must be kept depressed during all
automated motions to enable power to the
motors.
Note. Automated motions must be started
from the patient load position.
13. Place the point source holder at a distance
of approximately 1.85 meters (6 ft.) from
the detector to be calibrated.
14. Place a Tc-99m or Co-57 point source of
approximately 40 MBq or 1 mCi in the
holder.
15. Make sure that the entire detector FOV is
exposed to the source and that the count
rate is < 40 kcps.
16. When the source is in position, click Start
to begin the calibration.
