Fully digital processing device for positron emission tomography electronics system

Abstract

The invention relates to a fully-digitalized processing device of a positron emission tomography imaging electronic system, relating to the technical field of medical imaging, in particular to the field of positron emission tomography imaging, more particularly relating to electronics, signal processing and data processing methods and equipment in the positron emission tomography imaging system. The technical scheme of the invention is that the positron emission tomography imaging electronics system comprises detectors, a fully-digitalized electronics system and an image working station, wherein the detectors are annularly arranged in an arrayed way. According to the invention, the structure and the system are greatly simplified; and because the PET (Positron Emission Tomography) signal detection and processing, data acquisition, and the like are realized in a fully-digitalized way, the system integration level is high, the functions are powerful, the processing real-time property is good, the performance is stable and reliably, and the system function adjusting and upgrading are convenient. In the assembly process, the system can be conveniently adjusted and corrected, and the production cost and the production cycle of PET imaging equipment are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to the field of positron emission tomography, in particular to methods and equipment for electronics, signal processing and data processing in a positron emission tomography system. Background technique [0002] Positron Emission Tomography (PET) is a nuclear medicine imaging technique. It can perform real-time, non-invasive and dynamic in vivo imaging of functional information of human tissues at the molecular level, such as physiological and pathological changes, and can be used in early detection, diagnosis, grading, treatment plan formulation, curative effect evaluation and tracking of cancer, etc. , recurrence detection and other aspects have an irreplaceable role. [0003] The basic principle of PET imaging is: injecting radioactive isotopes (such as F 18 etc.) labeled drugs that reach the internal organs and tissues of the human body. Radioactive isotopes release b...

Problems solved by technology

The traditional method is to use multiple separate components to realize these functions, which is bulky, the connection between components is complicated, the detection and debugging are cumbersome, not only the cost is high, but the overall reliability of the system is poor

Due to the single and fixed functions of these separated components, the adjustment and upgradeability of the system functions are poor, and it is difficult to meet the update and development of modern technology and clinical applications.

[0005] These factors have caused the traditional PET imaging equipment to have a complex structure, high design and production costs, and a long production cycle.
