1. A detector unit for a positron emission tomography (PET) imaging system that includes a gantry having a patient-receiving tunnel, wherein the detector unit comprising:
a plurality of detector elements in a helical arrangement around an axial axis of the PET imaging system;
each detector element is offset from an adjacent detector element along a direction parallel to the axial axis of the PET imaging system by an axial gap such that a maximum difference between axial positions of detector elements in the detector unit is less than or equal to the axial gap.
