  • Systems and methods for detector sensitivity calibration in nuclear medicine imaging
    Patent number: 10564301
    Abstract: Methods and systems are provided for adjusting sensitivity of detectors in a nuclear medicine imaging system based on a sensitivity table. In one embodiment, a method comprises acquiring, with a detector including a collimator, scan data of a subject administered with a radioisotope; calculating a sensitivity of the detector based on the collimator and the radioisotope; and calculating a quantitative parameter from the acquired scan data of the subject based on the calculated sensitivity. In this way, SPECT quantitation may be accurately performed due to the increased accuracy of detector sensitivity for a given collimator and radioisotope without specifically calibrating the detector for the given collimator and radioisotope.
