Detector:
Intrinsic no collimator. One detector at a time.
Source:
Tc-99m ~ 7–20 MBq or 200–500
µ
Ci point source, yielding
20 kcps or less.
Source holder:
Point source holder.
Mask:
FOV mask (part no. 2163-5519)

Approximately 45 minutes per detector.
10.3.2
Test Procedure
Note
. If the CardioMD system is equipped with the AC Option, the transmission scanners must be
removed before the NEMA Uniformity test can be performed. See Chapter 12
CardioMD AC
Option
for instructions.
Procedure Details
1.
In the NEMA menu, select Uniformity.
The Uniformity page appears.
2.
In the Energy field, enter 140.5 for Tc-
99m.
3.
Check Detector 1 or Detector 2 to specify
the detector to be measured.
4.
Click Continue.
5.
Click OK to accept automated motions.
Automated motions will now position the se-
lected detector for measuring uniformity.
Note
. Automated motions must be started from the patient load position.
Note
. The detector positions used are the same as the ones used for energy resolution measuring.
