Procedure
3. On the acquisition PC's Persistence page,
click the Tools button.
The Calibration & Configuration menu ap-
pears.
4. In the Calibration & Configuration menu,
click CORCOR.
The CORCOR page appears displaying default
settings for Energy, Window Width and Ter-
mination counts in first view.
5. If the settings are acceptable, continue the
procedure.
If the settings are to be changed, enter the
new energy value for the appropriate iso-
tope.
For example, keep the 20% window width but
set Termination counts in first view to 25000
(25 kc). The default is 100 kc but 25 kc is
sufficient and less time consuming.
6. Use a Co57 point source or fill the vial
with Tc-99m.
If the vial is used, it must be filled with be-
tween 0.2 and 0.3 milliliters. Use a syringe to
fill the vial cautiously so that no activity ends
up on the walls of the vial. Seal the vial with
the lid. The point source should be 40–
120 MBq or 1–3 mCi.
7. Place the point source in the COR source
holder supplied with the system.
