Gamma camera components
The gamma camera consists of a series of different components, which isolate, amplify, detect, and display the intensities of gamma photons emitted from medical tracers in the tissue beneath the camera. Broadly, components of a gamma camera and spect imaging device consist of a detector (collimator, detector, photomultiplier tube, and preamplifier), processing (position logic circuit, amplifier, correction circuit, pulse height analyzer), and display (monitor) units (cherry et al., 2003). A gamma camera, also called a scintillation camera or anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy. Its requirements are quite different from a photography camera.
