Abstract: An imaging system is provided that includes a pixelated detector and a processing unit. The pixelated detector has individually read pixels. The processing unit is configured to count events detected by the detector unit using an energy window for each pixel. The energy window is individually tailored for each pixel, and is defined by an upper energy boundary corresponding to a higher energy level and a lower energy boundary corresponding to a lower energy level. At least one of the upper energy boundary or the lower energy boundary of the energy window is adjusted based on acquired events. The processing unit adjusts the at least one of the upper energy boundary or the lower energy boundary of the energy window for a given pixel before counting the events for the given pixel.

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.
