Problems solved by technology

However, due to the relatively low signal-to-noise ratio and resolution of ultrasound imaging, traditional feature extraction methods are difficult to obtain efficient expression of lesion features. Therefore, the accuracy of pathological classification of breast cancer using ultrasound images is relatively low. Therefore, a method is proposed. An accurate image processing, feature extraction and recognition method for ultrasound images of breast cancer to facilitate the use of ultrasound images by follow-up personnel is a technical problem that needs to be solved urgently in the market

The method comprises the steps of acquiring an ultrasound image, wherein the corresponding content of the ultrasound image comprises a breast part; processing the ultrasonic image to obtain a target area in the ultrasonic image, the target area including a mammary gland lesion area image; extracting a first feature and a second feature from the ultrasonic image with the identified target area; performing fusion processing based on the first feature and the second feature to obtain a first fusion feature; performing feature screening processing on the first fusion feature to obtain a second fusion feature;and based on the second fusion feature, obtaining a typing result of the breast cancer ultrasonic image. According to the method, high-throughput ultrasonic image features and deep semantic features are extracted, fusion and feature screening are carried out, and effective and accurate recognition of the ultrasonic image is realized.

Description

technical field [0001] The invention relates to the field of ultrasonic medical technology, and belongs to the field of identification and processing of ultrasonic images, in particular to a breast cancer ultrasonic image identification and typing method and a corresponding system that integrates deep convolutional network and radiomics features. Background technique [0002] With the continuous development of medical equipment, ultrasonic imaging equipment has become one of the most widely used medical equipment and tools in clinical practice because of its non-invasive, real-time, convenient operation, and low price. The commonly used functional modes of ultrasound imaging include two-dimensional black and white (B) mode, spectral Doppler mode (PW / CW) and color flow mode (CF / PDI). The B mode relies on the amplitude of the ultrasonic echo signal for imaging, and what is obtained is the two-dimensional structure and shape information of the tissue. The greater the echo signa...
