Abstract

The invention provides a method for dividing a breast three-dimensional image and a device thereof. The method for dividing a breast three-dimensional image comprises a step of inputting the breast three-dimensional image and converting the breast three-dimensional image into a two-dimensional image, a step of obtaining the object boundary line of two-dimensional image by a dynamic programming method, and a step of reconstructing the division result of a breast based on the object boundary line of two-dimensional image, wherein the boundary line is the position of the breast in the two-dimensional image after the outer surface of the breast is converted. According to the scheme, the gray, gradient and shape features of the breast three-dimensional image are combined, and the automatic three-dimensional division is accurately and effectively realized.

Description

technical field

[0001] The invention relates to the field of image segmentation, in particular to a method and device for segmenting three-dimensional breast images. Background technique

[0002] Breast cancer is the most common malignant tumor in middle-aged and elderly women, and its morbidity and mortality are increasing year by year. The curative effect of breast cancer depends more on the stage of the disease, especially in early breast cancer, the cure rate of ductal carcinoma in situ can reach 95%. Therefore, the early detection and diagnosis of breast cancer can effectively improve the cure rate of breast cancer. In clinical practice, magnetic resonance images have been widely used in risk prediction and early diagnosis of breast cancer, and the computer-aided diagnosis system helps to improve the accuracy and efficiency of radiologists in reading 3D magnetic resonance images. In the computer-aided diagnosis system based on 3D magnetic resonance images, the segmenta...
