ARTICULATING DETECTOR ARRAY FOR A GAMMA CAMERA

摘要

An articulating detector array (24) for gamma cameras is disclosed which is adaptable to perform different imaging techniques in a single apparatus. The articulating detector array is adapted to detect incident gamma radiation from diverse directions as well as Compton scattering thereof without the need of a collimator. The detector array includes radiation detectors (26, 28) in an array and movable to a plurality of positions (34, 36), in which each radiation detector is responsive to gamma radiation from a target for generating detection signals for use in tomographic imaging of the source. The detector array includes articulating support structures (30) for moving the detectors from a first position to a second position.
