Abstract

The invention discloses a full-digital electronic system of a full-digital processing device, and relates to the technical field of medical imaging, in particular to the field of positron emission tomography (PET). The full-digital electronic system comprises a plurality of original event detection modules with the same number as detectors which are arranged in an annular array form, a system event sorting device, a system event transmitting device, and a power supply and a clock control device which are provided for the original event detection modules, the system event sorting device and the system event transmitting device, wherein each original event detection module is connected to the corresponding detector through an analog/digital (A/D) converter; and the output end of each original event detection module is connected to the input end of the system event transmitting device through the system event sorting device. The full-digital electronic system can meet the requirement of the full-digital processing device of a full-digital processing PET electronic system.

Description

technical field [0001] The invention relates to the technical field of medical imaging, in particular to the field of positron emission tomography. 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 beta particles as they decay. After the beta particle is annihilated in the human body, a pair of gamma photons with opposite directions...
