Abstract
A variable PET apparatus allows structural changes of detector modules in transversal and longitudinal directions to correspond to various imaging purposes and a cross-sectional diameter of a subject while maintaining an arrangement of the detector modules to be close to a true circle. The variable PET apparatus includes: a gantry having an opening on a longitudinal axis; and detector modules supported on the gantry and arranged a predetermined distance apart from each other such that a detection ring is configured with a diameter in a circumferential direction, wherein the gantry is driven by a gantry drive member, and the detector modules are driven by a detector module drive member. According to the present invention, structural changes of the detector modules in the PET apparatus is possible to correspond to a cross-sectional diameter of a subject without additional devices, thereby improving the spatial resolution and sensitivity.
