Abstract
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.
