A gamma radiation detecting apparatus includes a gamma radiation collimator, a scintillation crystal, a charge coupled device, and an electronic device. The collimator receives and collimates gamma radiation. The scintillation crystal receives the gamma radiation from the gamma radiation collimator and converts the gamma radiation into visible light. The charge coupled device receives the visible light from the scintillation crystal and converts the visible light into an electrical charge. The electronic device converts the electrical charge into a digital image.
