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

High spatial resolution scintigraphic device having collimator with integrated crystals

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 ( ) are positioned mutually adjacent, each provided with its own independent electronic circuits ( ), and a circuit ( ) for interrogating the respective synchronism signals drawn from the respective electronic circuits ( ) determines the signal indicating the photomultiplier ( ) that detected the event and enables only a corresponding analogue switch ( ) to transfer the signals carrying the position co-ordinates of the event from the enabled electronic components ( ) to an analog to digital converter (A/D).
