Embodiment Construction

[0071] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0072] As described in the background, the existing control method of the high-voltage generator has the problem of fluctuations in the output voltage of the high-voltage generator before and after dose switching. The inventor found that the reason for this problem is as follows.

[0073] figure 1 It is a schematic diagram of an existing connection structure between a high-voltage generator and a ball tube. see figure 1 , Exemplarily, the voltage output from the high voltage generator 10 to the bulb 20 remains ...

Abstract

The invention discloses a method and device for controlling a high voltage generator, and a medical apparatus. The method comprises steps that an instruction of a ball tube no-load state sent by a control system is obtained, the tube current is turned off, a first control manner is utilized to obtain the first modulation amount information of the high voltage generator; and/or an instruction of aball tube working state sent by the control system is obtained, the tube current is turned on, a second control manner is utilized to obtain the second modulation amount information of the high voltage generator; the first modulation amount information or the second modulation amount information is inputted to the high voltage generator, and the first control manner and the second control manner are different. Compared with the prior art, voltage fluctuation of the high voltage generator caused before and after dose switching is suppressed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of control, and in particular to a control method and device for a high-voltage generator, and a medical instrument. Background technique [0002] Digital Subtraction Angiography (DSA) system obtains a clear display of blood vessel images by subtracting dose pulse imaging results with a mask. DSA is an inspection method that combines computer and conventional X-ray angiography . DSA has the advantages of high contrast resolution, short examination time, and less contrast agent consumption. It is of great significance in the clinical diagnosis of vascular diseases. [0003] In the prior art, in order to reduce the radiation dose of patients and doctors, and at the same time meet the continuous visibility requirements of therapeutic diagnosis, it is necessary for the high-voltage generator in the DSA system and the bulb connected to the high-voltage generator to control the bulb acco...
