In a gamma ray imaging camera having a scintillation crystal and a plurality of phototubes, two channels are provided for receiving and processing radiation of two different energy levels arising from injection into a patient of two different radioisotopes. Signals in the two energy ranges may both be recorded for future analysis or may be displayed side-by-side on an oscilloscope. Regardless of whether one or two isotopes are used, information describing the locations of scintillation in the crystal may be digitized, recorded, and played back for visual display at a later time. Alternatively, the location information may be displayed immediately. Calibration means are also provided for presenting the output of each phototube individually on an oscilloscope so that the apparatus may be adjusted to correct for variations inherent in phototubes.
