Abstract
A PET imaging system includes a gantry having a patient tunnel and a first detector unit and a second detector unit housed inside the gantry, each including a plurality of detector elements in a helical arrangement around an axial axis of the imaging system. Each of the detector elements in the second detector unit is spaced apart from a corresponding detector element in the first detector unit by an axial gap. Each detector element has an axial position. Each of the first and second detector units has its detector elements arranged so that a set of the detector elements is positioned such that each detector element in the set is offset from an adjacent detector element in the detector unit such that a maximum difference between axial positions of detector elements in each detector unit is less than or equal to the axial gap.
