An articulating detector array 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, as so has improved gamma ray detection efficiency. The detector array includes radiation detectors in an array and movable to a plurality of positions, 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 for mounting the detectors to the base and for moving the detectors from a first position to a second position. In one embodiment, the articulating support structures includes a first portion connected to a detector; and a second portion connected to the base, in which the first portion is adapted to extend from the second portion from the first position to the second position. In another embodiment, the articulating support structures include a pivot for pivotably mounting the detectors and for rotating the detectors from a first position to a second position.
