Abstract

The embodiment of the invention discloses a breast imaging system and an optical path device thereof. The optical path device comprises an interferometer, wherein the interferometer is used for diffracting X-rays emitted by an X-ray tube; an optical filter, wherein the optical filter is used for filtering the X-rays emitted by the X-ray tube; an X-ray tube, wherein the X-ray tube is used for outputting X-rays to the interferometer and the filter simultaneously; a detector, wherein the detector comprises a first detection part and a second detection part, wherein the first detection part is used for detecting first X-ray imaging data corresponding to X-rays passing through the breast tissue and the interferometer; the second detection part is used for detecting second X-ray imaging data corresponding to the X-rays passing through the filter and the breast tissue. The device solves the problem that a prior breast imaging system cannot give consideration to the image quality of a breast absorption image, breast phase contrast image and breast dark field contrast image, the technical effects of additional breast phase contrast images and breast dark field contrast images are provided while breast absorption images with high quality are obtained.

Description

Technical field [0001] Embodiments of the present invention relate to the field of medical equipment, and in particular, to a breast imaging system and its optical path device. Background technique [0002] In recent years, X-ray grating phase contrast imaging methods have aroused widespread research interest. Usually, in addition to the traditional X-ray tube and X-ray detector, the X-ray grating phase contrast imaging system also contains a Talbot-Lau interferometer composed of three gratings. Among them, the source grating (G0) is used to increase the spatial coherence of the X-ray tube, the phase grating (G1) is used to encode the phase information of the object, and the analysis grating (G2) is used to assist in detecting the interference fringes generated by the phase grating. The existing scanning X-ray grating phase contrast imaging system can realize full breast field of view phase contrast imaging, that is, it can generate breast phase contrast images, breast dark...
