ABSTRACT:
A scintigraphic device includes: a collimator for receiving and directing electromagnetic radiation from a source; a scintillation structure associated with the collimator for receiving the electromagnetic radiation from the collimator and converting it into visible radiation; an electro-optical converter combined with a suitable electronics and associated with the scintillation structure for receiving the visible radiation and converting it into electric signals; a processing unit connected to the electro-optical converter for receiving the electric signals and rebuilding, as a function of the electric signals, images of the source; an actuating system for mutually moving the source and the collimator to enable the collimator to detect the electromagnetic radiation at different mutual positioning locations of the source and the collimator, the processing unit being adapted to rebuild a plurality of auxiliary images representative of the source, each auxiliary image corresponding to a respective mutual positioning of the source and the collimator.
