Note: If you prefer to turn off the entire system every day, then allow at least 30 minutes
for system warm up before performing any calibration procedures or making any
measurements.
2. Schedule for performing the Quality Assurance (QA) Tests
a. Setting Up QA Parameters -- Once, at initial system setup (page 5-2)
b. Auto Calibration ---------------- Daily, before the first procedure (page 5-5)
c. Constancy Test ----------------- Daily, before the first procedure (page 5-11)
d. Chi-Square Test ---------------- Quarterly (page 5-15)
e. MDA Test ------------------------ Quarterly (page 5-19)
While performing any Quality Assurance test, ensure the following:
 Consistent placement of the radioactive standard source in the detector is critical.
The source should not be leaning against the sides.
 Keep background rates constant throughout the counting process by ensuring that no
radioactive sources or other dosed patients are in the immediate area.
Note: Perform all the needed QA procedures for one detector and then, repeat the
same for the second detector, if applicable.
3. Record Keeping – After the system is setup and all of the QA Tests have been
completed successfully, it is recommended that a list be printed of the system parameters
for your records (Refer to the VIEWING SYSTEM PARAMETERS section on page 5-23).
These are all of the default values used while doing various measurements (Thyroid
Uptake, Bioassay, Wipe Test etc.). In case of suspicious results in any module, confirm
the Setup values in that module with the values in your records. All QA results are stored
automatically and may be accessed at any time (Refer to the VIEWING AND PRINTING
HISTORY section on page 5-24).
