Nodule benign and malignant judgment device based on neural network

The invention relates to a nodule benign and malignant judgment device based on a neural network. The nodule benign and malignant judgment device comprises an image acquisition module used for acquiring an ultrasonic image with a nodule; the benign and malignant detection module is used for detecting benign and malignant nodules in the ultrasonic image through a neural network, the neural network comprises a feature extraction module and a feature classification module, the feature extraction module is connected with the feature classification module, the feature extraction module is used for extracting image features, and the feature classification module is used for classifying the image features; and the feature grading module is used for obtaining feature matrixes of different receptive fields based on the image features and performing result prediction on the feature matrixes of the different receptive fields. According to the method, benign and malignant nodules in the ultrasonic image can be accurately
