The tissue to be imaged is sectioned and placed on a scintillator. When charged particles deposit energy in a scintillator, the fluors are excited and emit light. This light is then lensed and detected with a cooled CCD camera. Since the alpha range is very short, the scintillator light is very localized so high resolution images can be obtained. The camera can be operated either in an integrating mode or in a quantum mode where single alphas can be seen as a function of time.
