Nodule grading system and method based on thyroid ultrasound image

Abstract

The invention provides a nodule grading system and method based on thyroid ultrasound images. The method comprises the steps: processing a first database to form a second database suitable for depth model processing; removing unreasonable second thyroid ultrasound images in the second database to form a third database; performing targeted modification on the third thyroid ultrasound image in the third database to form a fourth database; preprocessing a fourth thyroid ultrasound image in the fourth database to form a fifth database; extracting a part of fifth thyroid ultrasound images in the fifth database to form a training database; and through the trained model structure, performing nodule detection on the thyroid ultrasound image in an actual application scene to obtain a nodule grade. The nodule grading system based on the thyroid ultrasound image solves the problem of low accuracy in the thyroid nodule automatic identification and nodule grading process in the prior art.

Description

technical field [0001] The present invention relates to the technical field of computer artificial intelligence deep learning, in particular to a nodule grading system and method based on thyroid ultrasound images. Background technique [0002] The automatic recognition of thyroid cancer by traditional machine learning methods is often divided into two steps, first extracting features, and then using a classifier for classification. Commonly used feature extraction methods include SIFT, HOG, Haar-like, LBP features, etc. The quality of the extracted features determines the effect of automatic recognition; feature extraction requires constant parameter adjustment, which is a time-consuming and labor-intensive task. There is a great correlation, and experienced experts often extract more useful features, but there are not many technical personnel with such richness. Commonly used classifiers include SVM, decision tree, logistic regression, etc. Different classifiers have diff...
