Abstract

The invention discloses a thyroid tumor ultrasonic image recognition method and device, and the method comprises the steps: selecting a tumor region in a thyroid tumor ultrasonic image, extending a certain boundary scope and then performing cutting, carrying out the benign and malignant marking, and enabling the cut images to form a training set; training a selected CNN (Convolutional Neural Network) through the training set, and forming a thyroid tumor ultrasonic image recognition model; obtaining a to-be-recognized thyroid tumor ultrasonic image, selecting a tumor region and extending a certain boundary scope, and carrying out the benign and malignant recognition through the thyroid tumor ultrasonic image recognition model. The method and device are used for assisting a doctor to diagnose the benign and malignant thyroid tumors, obtain the accuracy of 90% or greater in the detection test of the benign and malignant thyroid tumors through the thyroid tumor ultrasonic image, and is ofgreat reference significance to the actual clinical diagnosis.

Description

technical field

[0001] The present invention relates to the field of image recognition, in particular to a deep learning-based ultrasonic image recognition method and device for thyroid tumors. Background technique

[0002] Epidemiological studies have shown that thyroid cancer is one of the most common malignant tumors in women, and its incidence has risen rapidly in recent years. Papillary thyroid carcinoma (PTC) is the main pathological type of thyroid cancer, accounting for a large proportion of the incidence. Ultrasound images are widely regarded as the main diagnostic tool for thyroid nodule screening and the preoperative evaluation method for PTC. Ultrasonographic features such as microcalcifications, high solid content, and irregular edges and shapes are typical for PTC considerations. The biggest limitation in the actual operation process is the dependence of the operator, and the accuracy of judgment of radiologists with different experience levels is different. ...
