Publication number: 20180110496Abstract: Methods and systems are provided for calibrating a nuclear medicine imaging system. In one embodiment, a method comprises: detecting, with a plurality of detectors, photons emitted by a calibration source comprising a radioactive line source and a fluorescence source, while pivoting one or more detectors of the plurality of detectors; and calibrating, with a processor communicatively coupled to the plurality of detectors, each detector of the plurality of detectors based on energy measurements of the detected photons. In this way, a two-point energy calibration of detectors can be performed with a single isotope, and without removing or adjusting a collimator attached to the detector.Type: ApplicationFiled: October 20, 2016Publication date: April 26, 2018Inventors: Moshe Levy, Jean-Paul Bouhnik, Yariv Grobshtein, Gil Amisar, Yaron Hefetz
