However, the above method has the following disadvantages: it relies too much on the class label information of the sample to determine the validity of the feature
But in fact, there are many images that do not have class label information, only some text description information; B-ultrasound images have image analysis text

Embodiment Construction

[0058] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0059] Such as figure 1 as well as figure 2 As shown, the present embodiment provides a method for verifying the validity of the computer-aided diagnosis of mammary ultrasound features, which specifically includes the following steps:

[0060] Step S1: Given an image set of breast B-ultrasound lesion areas with a medium scale or above, where the medium scale means that the image set contains at least 250 images of breast B-ultrasound lesion areas;

[0061] Step S2: Divide the breast B-ultrasound lesion area image set in step S1 into a training set and a verification set, and all breast B-ultrasound lesion area images are given image features v img and text features v text ; where the image feature v img It is a feature extracted from the breast B-ultrasound lesion area image, its validity is to be verified, and the text feature v text Obtained by ...

Abstract

The present invention relates to a method used for verifying feature validity of breast B-ultrasonography through computer-aided diagnosis. The method comprises the steps of: dividing a breast B-ultrasonography focus area image set into a training set and a verifying set, and providing given image features and textual features for all B-ultrasonography focus area images; performing binary coding for the textual features of all sample images in the training set and the verifying set; then performing breast B-ultrasonography feature verifying-oriented VALIDATION_RBM training based on the training set; and using the trained VALIDATION_RBM as a tool for verifying the feature validity. The method of the present invention can verify validity of image features by fully utilizing a mapping relation between breast B-ultrasonography image analysis texts and image features even in the case of no class tag information.

Description

technical field [0001] The invention relates to the technical field of feature engineering, in particular to a method for verifying the validity of B-ultrasonic features of computer-aided diagnosis of mammary glands. Background technique [0002] Breast cancer is one of the most common malignant tumors occurring in women. In recent years, the investigation and research of my country Anti-Cancer Association shows that the incidence rate of breast cancer is increasing year by year. Therefore, it is more and more meaningful to improve the accuracy of early diagnosis of breast cancer. [0003] At present, the main method used in the diagnosis of breast cancer is through imaging examinations such as mammary X-rays and B-ultrasound images, and the diagnoser analyzes the condition through imaging features such as calcification or mass. However, because the density of soft tissue such as glands, blood vessels, and fat in breast tissue is very close to the density of the lesion are...
