Abstract
Systems and methods described herein generally relate to object detection for nuclear medicine (NM) imaging. The systems and methods acquire triplets representing line of sights between a plurality of receive diodes and light emitting diodes (LEDs) positioned along a circumference of a gantry with respect to one or more objects of a patient. The systems and methods identify a number of the one or more objects based on a number of triplets for one of the LEDs. When a single object is identified, the systems and methods determine a shape of the single object based on a reference point within the single object and line of sights adjacent to the single object. Alternatively, when a plurality of objects are identified, the systems and methods utilize the line of sights to identify shapes of the plurality of objects.
