The invention relates to a medical image processing technology, and aims to provide a method for identifying benign and malignant breast nodules based on a shear wave elastic diagram of deep learning.The method comprises the following steps: collecting case data of an ultrasonic mammary gland common B-ultrasonic image and a shear wave elastic image with nodules, and constructing a benign and malignant classification data set according to a pathological result; selecting a basic network structure, replacing part of the convolution layer with a rotary pooling convolution layer, and constructinga benign and malignant identification network structure; adding nodule mask information to network input, performing data enhancement on a training set, and using separable Dropout calculation in thetraining process to improve the generalization ability of the model; and inputting a test image, carrying out multi-image-block and multi-model test to evaluate model performance, and carrying out breast nodule benign and malignant judgment on the image. Compared with a method for identifying benign and malignant parts by using a common B-ultrasonic image, the method can improve the benign and malignant diagnosis accuracy. According to the method, the rotation invariance can be learned, and the model recognition accuracy can be improved under the condition that the network calculation complexity is not increased.

The invention discloses an ultrasonic health care bra. The ultrasonic health care bra comprises a front bandage, a rear bandage and two cups, wherein the two cups are fixedly connected through the front bandage; the two ends of the rear bandage are fixedly connected with the two cups respectively; a control mechanism is arranged on the rear bandage; the control mechanism comprises a control assembly, a control unit, a communication unit, a pressure sensing unit, an inflation and deflation unit and a power supply unit; the power supply unit is used for supplying power to the control mechanism;the pressure sensing unit is used for acquiring pressure data of the back; each cup is of a double-layer structure; and a flexible bracket, an ultrasonic generator control circuit, an energy convertergroup and a core energy converter are arranged on the first layer. According to the ultrasonic health care bra disclosed by the invention, a built-in airbag and a sensor are combined, so that the ultrasonic health care bra can be adaptive to breasts with various sizes and ultrasonic massaging can be conveniently carried out on a user when the user needs, and furthermore, the health level of mammary glands is improved; and the ultrasonic health care bra has very good effects of alleviating mammary gland swelling pain in a menstrual period and preventing hyperplasia of mammary nodules.
