Abstract: A miniaturized scintigraphic device comprising a collimator (1), internally having a multiplicity of equal conduits (10) of determined length, identified and separated by septa (11) of minimum thickness in relation to the energy of the radiation, terminating in a common end plane (12) on the side opposite to the source of the event to be measured, comprising a scintillation crystal structure (2) and at least a photomultiplier (3), in which the scintillation crystal structure is constituted by a multiplicity of individual crystals (20) with polygonal section, each integrally integrated in proximity to the end, oriented towards the photomultiplier (3), of each conduit (10) of the collimator (1), having conforming polygonal section, and arranged in such a way that all the base faces (21) of the crystals (20) oriented towards the photomultiplier (3) are mutually coplanar and lying on a plane parallel to said common end plane (12) of the collimator (1).

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).
