Abstract
A positron emission tomography (PET) imaging device (10) includes a plurality of PET detector modules (18); and a robotic gantry (20) operatively connected to the PET detector modules. The robotic gantry is configured to control a position of each PET detector module along at least two of an axial axis, a radial axis, and a tangential axis of the corresponding PET detector module.
