Abstract

The embodiment of the invention discloses an X ray imaging method, device and equipment, and a storage medium. The method is applied to the X ray imaging equipment. The X ray imaging equipment comprises an area array light source, wherein the area array light source comprises a plurality of light sources. The method comprises the following steps of: controlling the plurality of light sources to scan the breast of a subject to obtain first projection data which is fused, and controlling the plurality of light sources to scan the breast to obtain second projection data which is fused, wherein the first projection data and the second projection data are projection data which is obtained through independent scanning under different energy rays or before and after radiography; and on the basisof a preset silhouette strategy, according to the first projection data and the second projection data, reconstructing a breast tomography image of the breast. By use of the technical scheme of the embodiment, after the area array light source is controlled to scan the breast, a DBT (Digital Breast Tomosynthesis) image which does not contain a motion artifact and simultaneously contains morphological information and reinforced information is constructed to achieve an effect that a region of interest is accurately detected from the breast.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of X-ray imaging, and in particular, to an X-ray imaging method, device, equipment, and storage medium. Background technique [0002] Mammography is a commonly used imaging examination method in breast examination. For example, Full-Field Digital Mammography (FFDM) projects a breast entity onto a two-dimensional image. [0003] However, normal, especially dense breasts have tissue overlap on two-dimensional images, which may block hidden regions of interest and cause false negative misjudgments, or some overlapping artifacts may be misjudged as false positives. The detection accuracy of ROI is low. Contents of the invention [0004] Embodiments of the present invention provide an X-ray imaging method, device, equipment, and storage medium, which solve the problem of low detection accuracy of a region of interest in a breast. [0005] In a first aspect, an embodiment of the present i...
