Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following examples and in conjunction with the accompanying drawings.

[0024] The invention provides a curved mirror capable of reflecting X-rays. The concave surface of the curved mirror is coated with multiple layers of reflective films capable of reflecting X-rays, and the layer thickness of the reflective films is designed to be Gradient distribution, after the incident X-ray beam is reflected by the reflective film, the outgoing X-ray beam becomes a parallel X-ray beam with the same frequency spectrum. In order to improve the signal-to-noise ratio of the image and reduce the image artifacts caused by the geometric parameters of the cone beam.

[0025] One surface of the X-ray filter mirror of the present invention is coated with multiple layers of reflective films that can reflect X-rays, and each...

Abstract

The invention relates to the field of medical equipment, in particular to a curved mirror. A plurality of reflecting films capable of reflecting X-rays are plated on the curved surface, and thicknesses of the reflecting films are in gradient distribution along a tangential direction of the curved mirror. Included angles exist between the curved mirror surface provided with reflecting films and incident X-ray beams, and the incident X-ray beams become parallel emergent X-ray beams with identical frequency spectra after being reflected by the reflecting films. The invention further provides an X-ray data acquisition system comprising the curved mirror. By means of the curved mirror and the X-ray data acquisition system comprising the same, the signal to noise ratio of images is improved, and image artifacts caused by geometric parameters of taper beams are reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a curved mirror capable of reflecting X-rays and an X-ray data acquisition system comprising the curved mirror. Background technique [0002] In the field of X-ray imaging, since the X-rays emitted by the X-ray tube have a continuous wide energy spectrum, for example, they are distributed in the range of 1-150keV, among which low-energy X-rays (such as 1-10keV) are meaningless to the final imaging results, and will Attenuated when passing through the tissues and organs of the human body. In order to reduce the radiation of low-energy X-rays to the human body, the current common practice is to arrange some thin layers of attenuating materials (hereinafter referred to as attenuation layers) in the direction of X-ray propagation to attenuate the low-energy X-rays before they reach the human body. , but the attenuated X-ray still has a continuous wide energy spectrum, such as 10-150...
