Abstract
A gamma camera for imaging radiation emitted from or transmitted by an object including a gamma camera head having a front input surface which produces signals, when a photon associated with the radiation is detected by the head, indicative of the position of the position of the detection on the input surface and at a given resolution in the absence of dithering of the head; and a dithering system which differentially translates the detector head or the object in at least one direction parallel to the input surface so that the dithering system translates the detector head or the object by an amount at least equal to the given resolution but less than 50 times the given resolution during acquisition of the signals.
