Method and system for determining size of esophageal cancer hypovascular region

Abstract

This application provides a method and system for determining the size of an esophageal cancer hypovascular area, which relates to the field of medical assistance technology and solves the current problem of lack of accurate measurement of an vascular area. The image of the lack of blood vessel area in the image; according to the image of the lack of blood vessel area, determine multiple different types of quantitative characterization values ​​of the image of the lack of blood vessel area; according to the multiple different types of quantitative characterization values, determine the final quantitative value and the lack of blood vessel area Region size results. The present application obtains multiple different types of quantitative characterization values ​​by quantifying the image of the lack of blood vessels, and obtains the final quantitative value of the size of the lack of blood vessels and the result of the size of the lack of blood vessels according to the multiple quantification of the characterization values, and realizes the detection of esophageal cancer in the magnified image of esophageal cancer. The identification and precise measurement of the size of the vascular-poor region of esophageal cancer can effectively assist endoscopists in predicting the depth of esophageal cancer.

Description

technical field [0001] The present application relates to the field of medical assistance technology, in particular to a method and system for determining the size of an vascular-poor region of esophageal cancer. Background technique [0002] Tumors, especially malignant tumors, are one of the most important killers of human death. The occurrence and development of tumors is accompanied by a series of changes in microvessels in tumors. Tumor blood vessels are a key pathway of tumor metabolism and a pathological process, the growth process of which includes two stages: prevascular and vascular. Tumor microvessel formation is closely related to tumor growth, invasion, metastasis and prognosis. Studies have shown that tumor microvessel density, as one of the criteria for measuring angiogenesis, is closely related to the malignant behavior and recurrence and metastasis of tumors. Due to the heterogeneity of the distribution of tumor neovascularization, that is, the blood vesse...

Problems solved by technology

[0005] However, in the process of clinical use, clinicians have different perceptions of the AVA region, resulting in differences in AVA recognition

At the same time, due to large changes in magnifying endoscopic parameters, endoscopists cannot accurately obtain information such as the magnification of the current field of view, and lack the means to accurately measure the AVA area. In the clinical decision-making process, physicians are more likely to identify AVA Empirical evaluation tends to be used, and AVA quantification standards are difficult to unify, which directly affects the judgment of the depth of esophageal cancer
