A nuclear medicine (NM) multi-head imaging system is provided that includes a gantry, plural detector units mounted to the gantry, and at least one processor. The at least one processor is operably coupled to at least one of the detector units, and configured to acquire, via the detector units, imaging information. The imaging information includes edge information and interior information. The edge information corresponds to a contour boundary of tissue and the interior information corresponds to an intermediate portion of the tissue. The least one processor is configured to control the detector units to acquire a proportionally larger amount of imaging information for the contour boundary than for the intermediate portion.
