Abstract
A method of calibrating a PET (Positron Emission Tomograph) scanner includes: PA1 acquisition of data from a plurality of coincidence radiation events, using at least one detector; and PA1 determination of values for a set with at least one calibration factor, which factor affects an analytically defined calibration criterion. Preferably, the detector has at least one rotating planar detector and the acquisition of data includes acquiring data from a plurality of rotational positions of the detector.
