SYSTEMS AND METHODS FOR SUMMING SIGNALS FROM AN IMAGING DETECTOR

摘要

A system includes a detector and a processing module. The detector includes pixels configured to detect an event corresponding to energy from a radiopharmaceutical. The processing module is configured to receive a request for each pixel that detects energy during a reading cycle. The processing module is configured to determine an energy level for each requesting pixel. For each requesting pixel, the processing module is configured to count the event when the energy level corresponds to an energy of the radiopharmaceutical, and to determine a combined energy level of the pixel and at least one adjacent pixel when the energy level does not correspond. The processing module is configured to count the event when the combined energy level corresponds to the energy of the radiopharmaceutical, and to disregard the event when the combined energy level does not correspond to the energy of the radiopharmaceutical.

1. A system comprising:
a detector comprising multiple pixels, the pixels configured to detect an event corresponding to energy received during a nuclear medicine (NM) scan using a radiopharmaceutical; and a processing module comprising at least one processor and at least one memory comprising a tangible and non-transitory computer readable storage medium, the processing module configured to: determine, responsive to a request for a reading of energy for an identified pixel of the detector that detects received energy above a predetermined level during a reading cycle, an energy level of the energy for the identified pixel; and for the identified pixel,
count the event for the identified pixel when the energy level of the identified pixel is determined to correspond to an energy of the radiopharmaceutical;identify an energy level of at least one adjacent pixel and determine the combined energy level of the identified pixel and the at least one adjacent pixel when the energy level of the identified pixel is determined not to correspond to the energy of the radiopharmaceutical;
count the event for at least one of the identified pixel or the at least one adjacent pixel when the combined energy level is determined to correspond to the energy of the radiopharmaceutical; and
disregard the event when the combined energy level is determined not to correspond to the energy of the radiopharmaceutical.
