What is the calibration procedure for the Gammed VI?

A factory calibration should be performed every 5 years as per manufacturer's specification. A constancy check source should be measured before each use to insure proper response of the instrument. The software contains many self-diagnostic tests which will flag the user for error conditions such as low battery, high zero offset or background.

Can the Gammed VI be used with FDG?

Yes. However, it requires the addition of a high-energy collimator for use with the CsI detector.
