Abstract
For dead time compensation, a point source with a same radioisotope as used for the radiopharmaceutical is positioned by the detector. Counts from the point source without the patient and with the patient are used to correct the system or detector sensitivity. Reconstruction is performed with the sensitivity normalized for count rate, compensating for the dead time and spectral broadening.
