Positron emission tomography device and method

Abstract

The invention provides a positron emission tomography device and method. The device comprises a detector system module and a computer system module which are detachably connected. The detector system module comprises a clock module, a detector, a switch and a power source; according to the computer system module, a detector configuration module and the detector are in detachable communication connection so as to perform parameter configuration on the detector; the input end of an imaging information obtaining module and the switch are in detachable communication connection so as to receive imaging information data; a pulse information analysis and processing module and the imaging information obtaining module are in communication connection so that the imaging information data can be converted into pulse time, energy and position information; a coincidence event screening module and the pulse information analysis and processing module are in communication connection and the pulse time, energy and position information can be converted into coincidence event pair information; an image rebuilding module performs image rebuilding. The device and method are applicable to a PET imaging system meeting any individual requirement, and rapid imaging for specific applications can be achieved at any time and any place.

Description

technical field [0001] The present invention relates to an imaging device and method in the field of medical imaging, and more particularly to a positron emission tomography device and method. Background technique [0002] Positron Emission Tomography (PET) is a cutting-edge molecular medical imaging device that can non-invasively, quantitatively and dynamically evaluate the metabolic level, biochemical reactions and functional activities of various organs in the organism. Due to the characteristics of functional imaging, PET is widely used in early diagnosis, treatment planning, efficacy evaluation of tumors, cardiovascular system diseases and nervous system diseases, as well as research on new nuclear medicine tracers and molecular probes, new drug development, targeted therapy technology, etc. It has unique application value in the research field. [0003] A traditional PET consists of three parts: a detector module, a data acquisition (Data Acquisition, DAQ for short) m...
