Abstract

The application relates to a Compton scattering event recovery method, a PET system and a computer-readable storage medium. Wherein, the method includes: obtaining the energy value detected by the first photosensor array, and the photosensor array-scintillation crystal response matrix; The position of the first scintillation crystal that detects the photoelectric effect event; according to the position of the first scintillation crystal and the energy value detected by the first photoelectric sensor array, determine the first action point of the Compton scattering event. Through the present application, the problem of low recovery accuracy of Compton scattering events in the related art is solved, and the accuracy of Compton scattering event recovery is improved.

Description

technical field [0001] The application relates to the field of imaging equipment, in particular to a method for recovering Compton scattering events, a PET system and a computer-readable storage medium. Background technique [0002] PET is the fastest growing imaging technology in the field of nuclear medicine today, and is widely used in clinical testing. [0003] In the PET system, the back-to-back 511keV monoenergetic photons generated by the annihilation of positron and electrons interact with the detectors at both ends to be detected. Detectors generally use scintillation crystals as light conversion materials, and two kinds of response events occur between the 511keV gamma photon and the crystal: one is the photoelectric effect event, and the energy of the gamma photon is completely deposited through a collision, releasing a large amount of fluorescence The other is the Compton scattering effect event, where gamma photons collide with the outer electrons of crystal at...
