PET detector system with self-locking structure

Abstract

The invention discloses a PET detector system with a self-locking structure. The PET detector system with the self-locking structure structurally comprises a signal detection module, a coincidence electronics module, an image reconstruction module and a power supply module. The signal detection module converts gamma photons emitted into a crystal into visible light, carries out photoelectric conversion and analog-digital conversion, converts the visible light into a digital electric signal and transmits the digital electric signal to the coincidence electronics module, and the coincidence electronics module extracts time, energy and position information in the digital electric signal. Three kinds of information are transmitted to the image reconstruction module through the Ethernet and theupper computer, the image reconstruction module reconstructs an original image through an image reconstruction algorithm, and the power supply module is responsible for providing different power supplies for all devices in the electronics module. A self-locking structure is introduced into the self-locking photon receiving module, so that the imaging definition is effectively improved.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to a PET detector system with a self-locking structure. Background technique [0002] PET (Positron emission tomography, positron emission tomography) imaging technology is a technology that uses the principle of tracing and positron coincidence detection to display the functional changes of human tissues and organs at the tissue cell, subcellular, and molecular levels. Biological characteristics and biochemical metabolic processes such as cell metabolism, molecular binding and information transmission can detect abnormalities before clinical symptoms and signs and changes in tissue anatomy, which is conducive to early diagnosis of diseases. The application of PET technology in clinical practice plays an extremely important role in the early diagnosis of malignant tumors, tumor staging and grading, clinical curative effect evaluation and follow-up monitoring, identification of ...

Problems solved by technology

In a traditional crystal array, the crystal strips are cuboids, and the crystal strips are combined with adhesives such as optical glue to form an array. Although they are fixed together, the gap between the crystal strips There are still gaps, resulting in lower light yield and lower spatial and temporal resolution of the corresponding system, which has a great impact on the final imaging effect
