Claim 23:
24. A method of performing positron emission tomography (PET) scanning of a subject using a PET imaging system having a PET scanner with a set of detector structures that share a common axis and that are axially spaced apart from each other so as to define gaps between detector structures, each detector structure having one or more radiation detectors, the method comprising:
performing, via a controller of the PET imaging system, a first scan of a subject to capture a first PET dataset with a first axial field-of-view (FOV), wherein the set of detector structures are separated from each other by a first set of gaps between detector structures;
determining, via the controller and based on the first PET dataset, a second set of gaps between detector structures corresponding to a second axial FOV different from the first axial FOV;
applying, via the controller, the second set of gaps to the set of detector structures to change distances between detector structures; and
performing, via the controller, a second scan of the subject to capture a second PET dataset with a second axial FOV.
