Embodiment Construction

[0085] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0086] The traditional automatic breast density grading method first needs to segment the breast tissue, and needs rich prior knowledge to design features that can represent four different levels of breast density, then extract and select artificial features, and finally design different classifiers Complete breast density grading. Regarding the above existin...

Abstract

The invention provides an automatic breast density grading method and device. The method comprises: acquiring a target breast X-ray image; preprocessing the target mammary gland X-ray image; and taking the preprocessed target mammary gland X-ray image as a prediction sample, inputting the prediction sample into a preset target depth residual error network, and taking the output of the target depthresidual error network as a mammary gland density grading result corresponding to the target mammary gland X-ray image. The breast density classification method and device can effectively improve theaccuracy and efficiency of feature recognition of the mammary gland X-ray image, can effectively and reliably improve the high efficiency and intelligent degree of the classification process of the mammary gland density corresponding to the mammary gland X-ray image, and can effectively improve the accuracy of mammary gland density classification.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a method and device for automatic grading of breast density. Background technique [0002] Breast cancer is the tumor with the highest morbidity and mortality among women in the world, and breast cancer also ranks first in the incidence of female malignant tumors, and grading breast density has become a key research object in the early and precise diagnosis and treatment of breast cancer. With the rapid development of science and technology in the medical field, the technology of breast density grading through manual segmentation, feature extraction and grading of breast tissue can no longer meet the automation needs of modern breast medicine. Therefore, in order to effectively adapt to the development trend of intelligent diagnosis of big data in medical imaging, how to classify breast density more intelligently has become an important medical topic. [0003]...
