Abstract
A scintigraphic device, comprising a collimator, a scintillation crystal structure, a plurality of photomultipliers, electronic circuits for the determination of the position co-ordinates (XY) and energy of the event and their amplification for their subsequent transfer to an electronic processor, wherein photomultipliers (31, 32, 33, 3n) are positioned mutually adjacent, each provided with its own independent electronic circuits (121, 122, 123, 12n), and a circuit (13) for interrogating the respective synchronism signals drawn from the respective electronic circuits (12) determines the signal indicating the photomultiplier (13) that detected the event and enables only a corresponding analogue switch (14) to transfer the signals carrying the position co-ordinates of the event from the enabled electronic components (12) to an analog to digital converter (A/D).
