Abstract
An imaging apparatus includes a plurality of detector assemblies disposed for rotation about an imaging region. The detector assemblies may be adjusted between at least two relative angular orientations about the imaging region. The relative angular orientations are selected based on the size of an object within the imaging region. The center of the transverse fields of view of the detectors may be offset from the axis of rotation. Gamma radiation generated by positron annihilation events is detected and used to generate tomographic images.
