Abstract
A nuclear medicine imaging device includes a plurality of detector heads ( ) mounted to a movable gantry for rotation around an examination region ( ). The detector heads ( ) include a housing ( ) which surrounds a radiation sensitive crystal ( ) which converts received radiation events. A positioning mechanism on the gantry maintains a relationship between the detector heads ( ) such that the housing for one detector head lies adjacent to and overlaps the housing for another detector head. During an imaging event, the gantry rotates the detector heads ( ) about a region of interest ( ) while radiation events are sampled. At a predetermined position relative to the area of interest, the overlapping of the detector heads is reversed.
