Nuclear Medical Imaging
Crystal scintillation detector plates are widely used in Nuclear Medicine to image tissues containing gamma-emitting tracer compounds introduced into the patient. A matrix of photomultiplier tubes or other light sensors optically coupled directly to the detector or a window detect the scintillation photons produced in the crystal. The camera system electronics compute the locations of the scintillation events in the crystal and evaluate the corresponding intake of the tracer in the tissue. This information is expressed in the image.
