1. A Nuclear Medicine (NM) imaging system comprising: a gantry; at least a first imaging detector coupled to the gantry, the first imaging detector being a non-moving detector; at least a second imaging detector coupled to the gantry, wherein the second imaging detector is a moving detector, wherein the first imaging detector is larger than the second imaging detector and the first and second imaging detectors comprise different detector configurations; and a controller configured to control the operation of the first and second imaging detectors during an imaging scan of an object to acquire Single Photon Emission Computed Tomography (SPECT) image information such that at least the first imaging detector remains stationary with respect to the gantry during image acquisition.
