Lymph node metastasis image analysis system, method and equipment based on deep learning

Abstract

The invention belongs to the field of image analysis, particularly relates to a lymph node metastasis image analysis system, method and equipment based on deep learning, and aims to solve the problem that in the prior art, whether lymph node metastasis occurs in a non-small cell carcinoma image cannot be well predicted noninvasively. The method comprises the steps of obtaining a to-be-analyzed CT image containing a lesion microenvironment, obtaining an imaging sign and clinical information of the same subject as the CT image, extracting one-dimensional CT image features and one-dimensional clinical information features respectively, performing feature enhancement and normalization processing, performing fusion through a full connection layer to generate a fusion feature vector, and classifying the fused feature vectors to obtain an analysis result. The non-small cell lung cancer lymph node metastasis image data classification method achieves classification of non-small cell lung cancer lymph node metastasis image data, has good robustness and generalization ability compared with an existing traditional vector model based on predefined image features, and effectively improves the prognosis effect of a patient.

Description

technical field [0001] The invention belongs to the field of image analysis, and in particular relates to a deep learning-based lymph node metastasis image analysis system, method and equipment. Background technique [0002] Lung cancer is one of the malignant tumors with the fastest-growing morbidity and mortality. Due to differences in gender, age, race, and geographical location, the incidence of lung cancer also varies greatly. Its main subtypes include squamous cell carcinoma and large cell carcinoma. and lung adenocarcinoma. [0003] For patients with early-diagnosed non-small cell lung cancer, if a more accurate preoperative classification can be obtained, the postoperative survival period is usually longer and the quality of life is also higher. Especially for the lymph node metastasis of early non-small cell lung cancer, it is difficult to find the effective characteristics of lymph node metastasis by naked eyes through CT and other imaging methods. Therefore, the ...
