Embodiment 1

[0017] Embodiment 1: refer to Figure 1-4 , a shielding collimation structure of an X-ray source, comprising an X-ray tube 10, a tube shield 11, a beam limiting mechanism 2, a beam limiting shield 12 and a light field collimation plate 3, the tube shield 11 and a beam limiting shield The cover 12 is connected end to end, the lower end of the beam limiting shielding cover 12 is provided with an opening for X-ray emission, the X-ray tube 10 is arranged in the tube shielding cover 11, the beam limiting mechanism 2 is arranged in the beam limiting shielding cover 12, and the optical field collimation plate 3 is movable and close to the opening of the beam limiting shield 12.

[0018] In this embodiment, only part of the X-rays emitted by the X-ray tube 10 can be emitted through the beam limiting mechanism 2, and the rest of the X-rays will be filtered and absorbed by the tube shield 11, or filtered and absorbed by the beam limiting mechanism 2, and at the same time , the X-rays i...

Abstract

The invention relates to the technical field of X-ray shooting equipment, and particularly relates to a shielding and collimating structure for an X-ray source. The technical scheme adopted in the invention is as follows: the shielding and collimating structure for the X-ray source comprises an X-ray bulb tube, a bulb tube shielding case, beam-limiting mechanisms, a beam-limiting shielding case and light-field collimating plates, wherein the bulb tube shielding case and the beam-limiting shielding case are connected end to end, an opening for shooting X rays out is formed in the lower end of the beam-limiting shielding case, the X-ray bulb tube is arranged in the bulb tube shielding case, the beam-limiting mechanisms are arranged in the beam-limiting shielding case, and the light-field collimating plates are movably arranged at the opening of the beam-limiting shielding case. The shielding and collimating structure has the advantages that the X rays at the X-ray source are shielded andprotected through cooperation of the beam-limiting mechanism with beam-limiting and shielding effects and the bulb tube shielding case, the beam-limiting shielding case and the light-field collimating plates which are arranged outside, so that the X-ray source is capable of emitting the X rays with strong purposiveness outwards, meanwhile, radiation leakage of the X-ray source is greatly reduced,and the safeties of medical workers and patients are protected.

Description

technical field [0001] The invention relates to the technical field of X-ray imaging equipment, in particular to a shielding and collimating structure of an X-ray source. Background technique [0002] Shielding and collimation of X-rays is an important protective measure for medical X-ray detection. Use the beam limiter and install it at the exit end of the ray emitting window of the X-ray tube. According to the needs of diagnosis, adjust the X-ray radiation range by adjusting the opening size of the lead plate on the beam limiter to adapt to different sizes. Check the area and reduce unnecessary X-ray radiation to the human body. The shielding effect of the structure that adjusts the X-ray radiation range used by the current X-ray machine is poor, and a large number of unshielded X-rays scatter to the surroundings, endangering the health and safety of people in the surrounding environment and the examinee. At the same time, a large number of stray scattered rays directly ...
