Abstract

The invention relates to a breast tumor classification method and device based on ultrasound image feature correlation. The method includes: carrying out preprocessing denoising on a breast ultrasound image, and extracting a target region of interest; extracting low-level image features on the basis of each pixel point in the target region of interest; and utilizing a covariance matrix to extract the feature correlation according to the low-level image features, adopting a data mining-based classifier to classify the feature correlation, and then obtaining a classification result of a breast tumor.

Description

technical field [0001] The invention relates to a breast tumor classification method and device based on ultrasonic image feature correlation. Background technique [0002] Breast cancer has become one of the common malignant tumors in women, accounting for 25% of the incidence of cancer in women and 15% of the mortality rate. In recent years, the incidence of female breast cancer in my country has been increasing year by year, accounting for 23% of malignant tumors, which seriously threatens the health and life safety of women. [0003] With the continuous development of medical imaging technology, imaging equipment such as mammography, ultrasound, MRI, and CT have been gradually applied to the detection of breast cancer. Mammography is a commonly used imaging analysis method for breast cancer. However, mammography images have poor resolution of soft tissues, and the diagnostic accuracy in dense breast cancer is low, only reaching 30%-48%. Ultrasound images are a common me...
