Problems solved by technology

However, in the detectors in the related art, it is difficult for the photomultiplier array of the photomultiplier tube array to locate the light of the small scintillation crystal array, and it is prone to a large probability of mislocalization, so it cannot achieve high spatial resolution. In addition, the small scintillation The crystal wil

Abstract

The invention discloses a PET detection module, a PET detector and a PET system. The PET detection module includes a plurality of detection units, and each detection unit includes a scintillation crystal and a silicon photoelectric multiplier tube which is in one-to-one coupling with the scintillation crystal so as to read scintillation signals of the scintillation crystal, and a part between two adjacent scintillation crystals is filled with a blocking material used for blocking rays. The PET detection module has the advantages of being high in space resolution, low in error positioning probability, and capable of improving imaging quality of the PET system and improving accuracy of disease diagnosis and the like.

Description

technical field [0001] The present invention relates to the field of positron emission tomography (Positron emission tomography, hereinafter referred to as PET), in particular, to a PET detection module, a PET detector with the PET detection module, and a PET detector with the PET detection module. PET system. Background technique [0002] PET is a non-invasive nuclear medicine imaging method. Its principle is to use radionuclide-labeled bioactive substances to participate in the physiological metabolism of organisms, and to indirectly observe the metabolism and three-dimensional distribution of bioactive substances by measuring the distribution of radionuclides. Condition. At present, PET technology has been widely used in clinical examination, including cancer, brain disease and heart disease examination. [0003] The PET system is mainly composed of detectors, electronics systems and reconstruction algorithm modules. Among them, the detector part is the core of the sys...
