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.

Abstract: Nuclear medicine (NM) imaging system includes a detector assembly coupled to a gantry. The NM imaging system also includes a positioning sub-system having a motion controller and a detector motor. The positioning sub-system also includes a proximity sensor device (PSD) coupled to a detector head of the detector assembly. The PSD is configured to be activated. In response to being activated, the PSD is configured to transmit an output signal to stop the detector motor from moving the detector head toward the object. The NM imaging system also includes a secondary circuit that, in response to the PSD being activated, is configured to determine whether the detector head has stopped moving toward the object and, if the detector head has not stopped moving toward the object, is configured to disable the detector motor.

Abstract: A medical imaging system is provided. Imaging detector columns are installed in a gantry to receive imaging information about a subject. Imaging detector columns can extend and retract radially as well as be rotated orbitally around the gantry. The system can automatically adjust setup configuration and an imaging operation based on subject shape estimation information.
