Breast focus classification and positioning method and device based on nuclear magnetic image

Abstract

The invention relates to a breast focus classification and positioning method and device based on a nuclear magnetic image, and the method comprises the steps: carrying out the two-dimensional segmentation of a to-be-processed first image sequence, which is obtained through the fusion of a plurality of image sequences of a target organ, and then carrying out the three-dimensional segmentation of the to-be-processed first image sequence; combining the connected regions in the obtained three-dimensional segmentation result to obtain a plurality of combined first focus sub-regions; and finally, according to the first focus sub-regions and the multiple groups of image sequences of the target organ, recombining and classifying the first focus sub-regions, and determining the category of the combined second focus sub-regions, wherein the category comprises a false positive category and a plurality of sign categories. According to the embodiment of the disclosure, the focus can be quickly and accurately identified from the mammary gland nuclear magnetic image sequence, and the reference type of the focus is given, so that the film viewing time of a doctor can be greatly saved, and the working efficiency and accuracy of the doctor can be improved.

Description

technical field

[0001] The present disclosure relates to the technical field of computer vision, and in particular to a method and device for classifying and locating breast lesions based on nuclear magnetic images. Background technique

[0002] As one of the common malignant tumors, the incidence of breast cancer is increasing year by year, and the age of onset is getting younger and younger, seriously endangering women's physical and mental health. Early detection, early diagnosis and early treatment of breast cancer are important factors to improve prognosis, therefore, early breast cancer screening and detection are becoming more and more important.

[0003] Magnetic Resonance Imaging (MRI) is an image examination method based on the principle of nuclear magnetic resonance, which has the characteristics of multiple imaging parameters and high tissue resolution. It has a good diagnostic function for brain, thyroid, liver, gallbladder, spleen, kidney, pancreas, adrenal gl...
