METHODS AND SYSTEMS FOR GAIN CALIBRATION OF PET DETECTORS |
| 摘要 |
Methods and systems are provided for performing cathode calibration in a detector assembly. In one embodiment, a method comprises adjusting a cathode bias of a detector based on a total number of events occurring in the detector during a time period while maintaining an anode bias at a desired value, the events corresponding to photon energy detected by the detector. In this way, an automated cathode calibration procedure may be applied to calibrate the detector assembly. |
