Abstract

The invention provides a method for determining a target point and a positioning system for a mammary gland X ray photography system. The method is applied to the mammary gland X ray photography system, and comprises steps of: repeatedly marking suspected lesions in a first stereo positioning image and a second stereo positioning image acquired by a target to obtain a plurality of mark point pairs; obtaining a spatial position corresponding to each of the plurality of mark point pairs in the target; based on the spatial position corresponding to each mark point pair in the target, obtaining athree-dimensional model, and determining a target point by the three-dimensional model. The method can help the user obtain the spatial position information of the suspected lesion, and comprehensively considers the spatial position information and the plane information of the mark points, thereby improving the accuracy of determining the target point.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for determining a target point and a positioning system for a mammography system. Background technique [0002] In order to prevent and alleviate the harm of breast diseases to women's health, accurate detection methods are needed to correctly diagnose the disease and take timely treatment methods, especially the accurate detection of small lesions (<10mm) can detect the disease as early as possible and prolong the life of women, but it is difficult Accurate diagnosis is made entirely by imaging. Clinically, microscopic lesions can be accurately diagnosed by needle biopsy or guidewire stereotaxic biopsy. If the puncture target point is not positioned accurately, the breast tissue extracted may not be the breast lesion tissue, and the biopsy result is inaccurate, resulting in The lesions are not diagnosed, which affects the life of women. Therefore, the requirements ...
