Method and system for determining size of esophageal cancer hypovascular area

Abstract

The invention provides a method and system for determining the size of an esophageal cancer hypovascular are, relates to the technical field of medical assistance, and solves the problem that accurate measurement of the hypovascular area is lacked at present, and the method comprises the following steps: obtaining an esophageal cancer dyeing magnified image and a hypovascular area image in the esophageal cancer dyeing magnified image; determining a plurality of different types of quantitative characterization values of the hypovascular area image according to the hypovascular area image; and according to the plurality of different types of quantitative characterization values, determining a final quantized value of the size of the hypovascular area and a size result of the hypovascular area. According to the method and the device, the multiple different types of quantitative characterization values are obtained by quantifying the vascularization region image, and the final quantized value of the vascularization region size and the vascularization region size result are obtained according to the multiple quantitative characterization values, so that the identification and accurate measurement of the vascularization region size of the esophageal cancer in the endoscope of the esophageal cancer dyed and amplified image are realized, and an endoscopic physician is effectively assisted in predicting the esophageal cancer depth.

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
