Abstract

The embodiment of the invention provides a method and device for automatically detecting a pectoralis major muscle region in a molybdenum target image. The method comprises the steps: carrying out thepreprocessing of a to-be-detected molybdenum target image, and obtaining a preprocessed molybdenum target image; inputting the preprocessed molybdenum target image into a pre-trained pectoralis majormuscle region detection model to obtain a probability image of a pectoralis major muscle region; and performing post-processing on the probability image of the pectoralis major muscle region to obtain a pectoralis major muscle region segmentation result, wherein the pectoralis major muscle region detection model is obtained by training based on a preprocessed molybdenum target image sample and apectoralis major muscle segmentation gold standard corresponding to the molybdenum target image sample. According to the embodiment of the invention, an accurate and effective molybdenum target imagepectoralis major muscle detection result can be provided for an existing mammary gland CAD system, so that the accuracy of a calculation and analysis result is improved, and better auxiliary diagnosisis provided for radiologists, and finally missing report and false report of case conditions are reduced.

Description

technical field [0001] The invention relates to the technical field of image processing, and more specifically, to a method and device for automatically detecting the pectoralis major region in a mammography target image. Background technique [0002] Breast cancer is one of the leading causes of cancer death in women. Currently, the most effective method for early detection of breast cancer is mammography screening. However, at present, radiologists analyze hundreds of mammography images every day, and the task is time-consuming and labor-intensive, which leads to under-reporting and false-reporting of some cases. Computer-aided diagnosis (CAD) system is becoming more and more popular as a "second reader's opinion" because of its consistency, reliability and speed. The CAD system can provide radiologists with effective auxiliary diagnostic opinions, which can improve the accuracy of mammography image detection. [0003] In the CAD system of the breast, the automatic dete...
