Problems solved by technology

[0003] However, due to the limitation of tube exposure in the limited angle range during DBT acquisition, it is impossible to obtain enough projection information to reconstruct tomographic images similar to CT. The interference of the high-density material projection produces interlayer artifact...

Embodiment Construction

[0047] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0048] The method for suppressing interlayer artifacts of breast tomographic reconstruction images provided by this application can be applied to such as figure 1shown in the application environment. Wherein, the terminal 1002 communicates with a DBT (Digital Breast Tomography) scanning system 1004 through a network interface. Specifically, the terminal 1002 acquires projection images at different angles from the DBT scanning system 1004, and the terminal 1002 performs initial reconstruction based on the projection images, and extracts the three-dimensional space mask of ...

Abstract

The invention relates to an interlayer artifact suppression method and device for a mammary gland tomographic reconstruction image, computer equipment and a storage medium. The interlayer artifact suppression method comprises the following steps: acquiring projection images of a scanned object at different angles, and performing primary reconstruction to obtain an initial reconstructed image; extracting a three-dimensional space mask of the high-density substance and a feature image of the high-density substance according to the initial reconstructed image; respectively mapping the three-dimensional space masks of the high-density substance, and combining the feature information of the projection image to obtain two-dimensional projection masks of the high-density substance of the projection image at different angles; obtaining an artifact weight image according to the two-dimensional projection mask and the pixel information of the projection image; performing weighted back projectionreconstruction on the projection image and the artifact weight image at different angles to obtain a reconstructed base image; and performing fusion processing on the reconstructed base image and thefeature image of the high-density substance to obtain a tomosynthesis reconstructed image after artifact suppression. According to the scheme, the quality of the reconstructed image can be improved.

Description

technical field [0001] The present application relates to the technical field of digital mammography, in particular to a method, device, computer equipment and storage medium for suppressing interlayer artifacts of breast tomographic reconstruction images. Background technique [0002] With the development of mammography technology, digital breast tomosynthesis technology (Digital BreastTomosynthesis, DBT) has emerged, which is based on digital mammography (Digital Mammography, DM), combined with the development of existing semiconductor detectors and digital Font layer synthesis technology, through the limited-angle rotation of the tube, and the projection data obtained by low-dose exposure of several angles to the compressed breast to reconstruct fine breast tomographic images of multiple horizontal layers. [0003] However, due to the limitation of tube exposure in the limited angle range during DBT acquisition, it is impossible to obtain enough projection information to ...
