Abstract

The invention relates to a distributed high-voltage power supply architecture for a PET system, comprising: more than two high-voltage components located in the PET system, each high-voltage componentis connected to a part of a detector module in the PET system; a low-voltage power supply module and a central control board are connected with each high-voltage component, and each high-voltage component converts the voltage supplied by the low-voltage power supply module into the high-voltage required by the detector module according to the control instruction of the central control board. Thelow-voltage power supply module and the central control board are connected with each high-voltage component. The invention has the advantages of low power consumption, low high-voltage output noise,high system integration and safety, accurate differential control and dynamic adjustment of high-voltage parameters, and simple system maintenance.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a distributed high-voltage power supply architecture for a PET system. Background technique [0002] Positron Emission Tomography (Positron Emission Tomography) is an imaging examination, auxiliary cancer tumor diagnosis and curative effect evaluation technology. functional imaging. A single detector requires a kilovolt-level power supply voltage, and the entire PET system contains hundreds of detectors, which form a modular ring structure; each detector module has different gains, and the demand for high voltage is also different; the high-voltage power supply The quality of the power supply directly determines the quality of the image. [0003] At present, the existing PET system high-voltage power supply structure adopts a centralized, single high-power high-voltage power supply to provide cascaded high-voltage power supply to the system, and uses the method of series resistan...
