CT power supply device, CT device and CT detection vehicle

Abstract

The invention discloses a CT power supply device, a CT device and a CT detection vehicle. The CT power supply device comprises an output end, a control module and at least two energy storage modules,and the output end is used for connection with a high-voltage generator. Each energy storage module is connected to the output end, and the control module controls whether to supply power to the output end or not; and when the preset condition is satisfied, the controller controls the energy storage module that supplies power to the output end to stop the power supply, and controls at least another energy storage module to supply power to the output end, that is, n groups of energy storage modules are being charged in normal states, and one group of energy storage modules is working in rotation. It not only enlarges the use area of CT device, but also avoids the disturbance to CT detection caused by the fluctuation of AC current of a power network. Moreover, the energy storage modules cansupply power in turn, which can ensure the quality of power supply to the high-voltage generator, for example, the amplitude of the provided voltage can meet the need of the normal operation of the high-voltage generator.

Description

technical field [0001] The invention relates to the field of CT equipment, in particular to a CT power supply device, a CT device and a CT detection vehicle. Background technique [0002] CT equipment uses X-ray beams to scan a layer of a certain thickness. The X-rays that pass through the layer are received by the detector and converted into visible light, which is converted from photoelectricity to electrical signals, and then converted into digital signals by analog / digital converters. , input into the computer for processing. For example, medical CT equipment uses highly sensitive instruments to measure the human body according to the difference in the absorption and transmittance of X-rays by different tissues of the human body, and then inputs the data obtained from the measurement into the computer, and the computer processes the data. , you can take a cross-sectional or three-dimensional image of the inspected part of the human body, and find small lesions in any pa...
