10.4.2 Test Procedure

Note. If the CardioMD system is equipped with the AC Option, the transmission scanners must be
removed before the NEMA Spatial Resolution test can be performed. See Chapter 12 CardioMD
AC Option for instructions.
Procedure
1. In the NEMA menu, select Spatial resolu-
tion and linearity.
The Spatial Resolution and Linearity 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 spatial resolution
and linearity.
Note. Automated motions must be started from the patient load position.
Note. The detector positions are the same as the ones used to measure energy resolution. See page
10-5.

Tc-99m ~ 150–200 MBq or 4–5 mCi point source yielding
20 kcps or less.
Point source holder.
NEMA X and Y Line Phantoms.
Approximately 2 times 15 minutes per detector.
