SYSTEMS AND METHODS FOR CALIBRATING A SILICON PHOTOMULTIPLIER-BASED POSITRON EMISSION TOMOGRAPHY SYSTEM |
摘要 |
A representative positron emission tomography (PET) system includes a positron emission tomography detector having one or more silicon photomultipliers that output silicon photomultipliers signals. The PET system further includes a calibration system that is electrically coupled to the silicon photomultipliers. The calibration system determines a single photoelectron response of the silicon photomultipliers signals and adjusts a gain of the silicon photomultipliers based on the single photoelectron response.
