Claim 0:
1. A positron emission tomography (PET) imaging system comprising:
a controller having a processor and a memory with instructions executable by the processor to control scanning of subjects;
a PET scanner having a set of detector structures sharing a common axis, each detector structure having one or more radiation detectors, wherein each detector structure has a corresponding axial width, and wherein the detector structures are spaced apart from each other along the axis to define gaps between detector structures in the set of detector structures such that an axial field-of-view (FOV) of the PET imaging system is greater than a sum of the corresponding axial widths of the detector structures; and
a scanner driver configured to adjust gaps between detector structures in the set of detector structures so as to adjust the axial FOV of the PET imaging system;
wherein the controller is configured to perform a first scan using the PET scanner with a first set of gaps between detector structures, determine a second set of gaps based on the first scan, control the scanner driver to adjust gaps between detector structures to correspond with the second set of gaps, and perform a second scan following adjustment of gaps.
