Abstract: A scintillation camera receives radiation from an object under examination and determines the locations of scintillation events. The camera issues x and y coordinate signals which correspond to these locations, and z unblank signals which correspond to the intensity of the scintillation events. Preferably, the scintillation camera can be moved along arc-shaped scanning paths. It is possible to generate a shift movement between the object and the scintillation camera between various pass positions. The output signals of the scintillation camera are forwarded to a display device via an electronic circuitry which encloses a square field of view. This square field of view has a fixed angular orientation with respect to a fixed coordinate system during each of the aforementioned arc-shaped scanning passes.
