1. A nuclear medicine (NM) imaging system comprising:

  • a gantry including a cavity that is sized and shaped to receive an object therein, the cavity being oriented relative to mutually perpendicular longitudinal, vertical, and horizontal axes, the cavity extending lengthwise along the longitudinal axis;

    a plurality of detector assemblies distributed at least partially around the cavity, each of the detector assemblies in the plurality including a movable arm and a detector head that is coupled to the movable arm, the movable arm configured to move the detector head toward and away from the object within the cavity; and

    at least one processor configured to execute programmed instructions stored in memory, wherein the at least one processor, when executing the programmed instructions, is configured to;

    determine a body contour of the object within the cavity, the body contour representing an exterior surface of the object positioned within the cavity;

    determine an acquisition configuration based on the body contour, the acquisition configuration including at least three of the detector heads positioned in a dense group that borders the body contour, the detector heads in the dense group being primary detector heads;

    move at least one of the object or one or more of the primary detector heads so that the primary detector heads are in the dense group near the object.
