Abstract
A scintillation camera, comprises the structure of a scintillation crystal (10), a collimator (20), a light guide (30), an array (50) of p photodetectors, p acquisition channels (60), and a processor (100) for supplying the coordinates x.sub.j and y.sub.j of a scintillation j and its associated energy E.sub.j, and further comprises structure characterized in that: PA0 (A) the p acquisition channels apply p digital signals to the input of the processor; PA0 (B) the processor (100) itself comprises: PA1 (a) a bus for transferring the p digital signals; PA1 (b) a digital summing stage (200); PA1 (c) a scintillation processing stage; and PA0 (C) a detection, sequencing and storage stage (400) which receives a signal which corresponds to the sum of the p output signals of the photodetectors, is provided in order to supply the various clock signals and the correction coefficients for the scintillation processing stage.
