Abstract
A gamma camera includes first and second detectors which face an examination region. The detectors are rotatable about the examination region and translatable in a direction tangential to the examination region. Translation of the detectors is coordinated with the rotation of the detectors about the examination so as to increase the effective field of view of the detectors. In a first embodiment, the detectors are translated in the transverse direction when the detectors are located at each of a plurality of positions about the examination region. In a second embodiment, translation of the detectors is coordinated such that, for a given projection angle, the first detector is used to detect radiation data from a subset of the region of interest.
