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 (3.sub.1, 3.sub.2, 3.sub.3, 3.sub.n) are positioned mutually adjacent, each provided with its own independent electronic circuits (12.sub.1, 12.sub.2, 12.sub.3, 12.sub.n), 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).

Um dispositivo scintigraphic, compreendendo um collimator, uma estrutura de cristal do scintillation, um plurality dos photomultipliers, circuitos eletrônicos para a determinação da posição coordena (XY) e energia do evento e seu amplification para sua transferência subseqüente a um processador eletrônico, wherein os photomultipliers (3.sub.1, 3.sub.2, 3.sub.3, 3.sub.n) são mutuamente adjacentes posicionado, cada um fornecido com seus próprios circuitos eletrônicos independentes (12.sub.1, 12.sub.2, 12.sub.3, 12.sub.n), e um circuito (13) interrogating os sinais respectivos do synchronism extraídos dos circuitos que eletrônicos respectivos (12) determinam o sinal que indica o photomultiplier (13) que detectou o evento e permite somente um interruptor análogo correspondente (14) de transferir os sinais que carregam a posição coordenam do evento dos componentes eletrônicos permitidos (12) ao conversor a digital análogo (A/D).
