1. A nuclear medicine (NM) multi-head imaging system comprising:
a gantry defining a bore configured to accept an object to be imaged, the gantry configured to rotate about the bore;
plural detector units mounted to the gantry and configured to rotate as a group with the gantry around the bore in rotational steps, each detector unit configured to sweep about a corresponding axis and acquire imaging information while sweeping about the corresponding axis; and
at least one processor operably coupled to at least one of the detector units, the at least one processor configured to:
determine a region of interest (ROI) of the object to be imaged;
determine a sweeping configuration based on the size of the ROI;
determine a rotational movement configuration for the gantry using the determined sweeping configuration; and
control the gantry and the set of detector units to utilize the determined rotational movement and sweeping configurations during acquisition of imaging information.
