Abstract
A gamma radiation camera system that utilizes a gamma blocking object which is removably located in the field of view of a gamma detector and blocks at least a portion of gamma radiation, emitted from a scene, from the detector and thereby forming a two-dimensional image of the scene. Further, individual components received by the detector from the scene provide an output signal to respective processing circuitry. The difference is then determined between components of a first output signal obtained when the object is present in the field of view of the detector and components of a second output signal obtained when the object is not present in the field of view.
