Problems solved by technology

[0003] However, there is currently no standard PET detector detection platform. The current mainstream detection method is to use an oscilloscope or a data acquisition card to manually collect data analysis results item by item according to specific measurement parameters. The whole process is time-consuming and labor-intensive, and the results are many Focus on single-channel performance
In the PET system, the performance of a single channel ultimately determines the performance of the entire system, but because the PET system has

Abstract

The invention provides a PET detector measurement method and system and a computer readable storage medium, electronic parameters are preset through an electronic measurement module, then coincidence data of two to-be-detected PET detector modules are measured, and finally analysis software is called to automatically analyze a measurement result, so that one-time acquisition can be realized. The time performance and the energy performance of the pixel level and the module level and the counting rate of the detector are automatically analyzed, and the performance of the module level detector is similar to the performance of the whole PET system, so that the performance of the whole PET system can be considered to be obtained. The method not only can be used for evaluating the intrinsic performance of the PET detector and detecting the coincidence performance of the two detectors, but also can be expanded to be used for detecting other radiation detectors, scintillation crystals and photoelectric conversion devices.

Description

technical field [0001] The present invention relates to the technical field of PET detectors, in particular to a measurement method, system and computer-readable storage medium for PET detectors. Background technique [0002] Positron Emission Tomography Scanner (PET) is a nuclear medicine imaging device, which is mainly composed of a detector system, an electronic system and a reconstruction system. The detector system consists of scintillation crystals, photoelectric conversion devices and front-end electronics. PET achieves tomographic imaging by collecting and judging a pair of gamma photons generated by a radioactive tracer injected into a living body. Simulate the electrical signal, and use the analog conditioning circuit to amplify the analog electrical signal and then measure the energy and arrival time information of the signal. By summarizing all the information measured by all detectors in the entire PET system, and rationalizing the information at the back end ...
