Abstract

The invention discloses an image acquisition method and device for an X-ray image system. The method comprises the following steps: collecting X-ray images at preset time intervals, and during each collection, if the number of the collected images is greater than 0, saving the currently collected images; and when a preset event occurs, performing accumulation for the images that are saved each time before the preset event occurs, and taking the accumulated images as output X-ray images. According to the image acquisition method and device for the X-ray image system disclosed by the invention, the X-ray images are continuously collected at the preset time intervals, the images of which the number is greater than 0 are saved, which means that the images collected in X-ray exposure are saved, the images saved each time are accumulated, and the accumulated images are taken as the output X-ray images so as to ensure that image information generated by the X-ray exposure can be sufficiently acquired, and the phenomenon that an image collection mode has a time conflict between the X-ray exposure and image collection in the prior art can be overcome.

Description

technical field [0001] The invention relates to the technical field of X-ray imaging, in particular to an image acquisition method and device of an X-ray imaging system. Background technique [0002] The X-ray imaging system refers to obtaining the image of the target after irradiating the target with X-rays. The main equipment of an X-ray imaging system includes an X-ray source device for generating X-rays and a detector for collecting images. [0003] In the prior art, the way the system detector collects images is to automatically collect images every preset time, but this method is likely to cause time conflicts between X-ray exposure and image collection. [0004] At present, in order to ensure that the image information generated by the X-ray exposure can be fully obtained, a method of controlling the synchronization of the X-ray exposure and the image acquisition by the detector is adopted. One of the synchronization methods is to add synchronization equipment to th...
