The Gamma Camera: Components & Detection System

For some years, nuclear images were obtained by using a rectilinear scanner. Currently, nuclear imaging is done with the use of a gamma camera. You can think that this camera takes a picture of a gamma-emitting radioactive source coming out from the patient injected with a radioactive substance.
