description The current invention presents designs of SPECT gamma cameras without the in-out mechanical motion of the detectors. The elimination of this motion is achieved by the implementation of iterative algorithms, such as Resolution Recovery and/or Wide Beam Reconstruction, which compensate for the Line Spread Function effect due to the collimator characteristics. The use of these methods enables construction of SPECT gamma cameras with a range of novel designs, having their gamma detector (or detectors) orbiting the patient in a predetermined orbit of fixed radius. For example, the radius might be chosen as such that the majority of all patients can be scanned by the system. This shows the advantages of the invention for gamma cameras with any numbers of detectors.
