Problems solved by technology
The current portable X-ray imaging devices are adjusted by doctors based on subjective experience, and it is impossible to display the position value in real time or whether the center points of the X-ray generating device and the X-ray receiving device are aligned, which often causes the imaging area to deviate from the X-ray The center of the receiving device, even if it is not in the effective imaging area of the X-ray receiving device
Or, in order to obtain a good X-ray image, the doctor will perform multiple exposures to adjust the positions of the X-ray generating device and the X-ray receiving device according to the previous images, which will result in doubling the radiation dose of the patient and cause serious harm to the patient. harm

The embodiment of the invention provides a positioning device for an X-ray imaging apparatus. The X-ray imaging apparatus comprises an X-ray generation apparatus and an X-ray receiving apparatus. The positioning device is installed on the X-ray generation apparatus or the X-ray receiving apparatus. The positioning device comprises: a position detection module for detecting a space position of the X-ray generation apparatus or the X-ray receiving apparatus; and a processing module for, based on the space position of the X-ray receiving apparatus or the X-ray generation apparatus, and the space position of the X-ray generation apparatus or the X-ray receiving apparatus, detected by the position detection module, calculating a relative position of the X-ray generation apparatus relative to the X-ray receiving apparatus or a relative position of the X-ray receiving apparatus relative to the X-ray generation apparatus, and displaying the relative positions. According to the embodiment of the invention, the relative positions between the X-ray generation apparatus and the X-ray receiving apparatus can be obtained.
Description
technical field [0001] The invention relates to the technical field of X-ray imaging, in particular to a positioning device for an X-ray imaging device. Background technique [0002] X-ray imaging methods can be applied to medical diagnosis, mainly based on X-ray penetration, differential absorption, photosensitivity and fluorescence. When X-rays pass through the human body, they are absorbed in different degrees. For example, the amount of X-rays absorbed by bones is more than that absorbed by muscles, then the amount of X-rays after passing through the human body is different, which will carry the density distribution of various parts of the human body. The intensity of the information on the receiving device is quite different, so images with different brightness can be presented. [0003] An X-ray imaging device usually consists of an X-ray generating device and an X-ray receiving device. The X-ray generating device generally consists of a high-frequency and high-volta...
