Abstract
In a scintillation camera having apparatus for shortening waveforms, a regulating circuit for preventing display of signals representing unwanted .gamma. rays having excessive intensity including a device for comparing the peak of the shortened waveform representing the total light energy received by the camera from the .gamma. ray with a preset reference range between an upper limit and the saturation level of the pre-amplifiers of the camera and for generating a signal while the total light energy exceeds the reference range, a circuit for generating an output for a predetermined time after the signal ceases and an AND gate for blocking access to the display during the period of the output.
