Abstract

The invention discloses a wrapping-degree determination method and device for a the tumor-wrapping vessel and relates to the technical field of biomedicine with a main aim to be capable of ensuring accuracy in wrapping-degree calculation of the tumor-wrapping vessel. The method includes: acquiring vascular segmentation images which are acquired by subjecting the tumor-wrapping vessel to vascular segmentation; identifying vascular contours of the vessel according to vascular points segmented according to the vascular segmentation images; determining points that the vessel is adhered to the tumor by traversing the points in the vascular contours and two points in the vascular contours in a manner of neighboring back and forth; determining contour length of the vascular contours by traversing the points in the vascular contours and determining wrapping length of the tumor-wrapping tumor by traversing the points where the vessel is adhered to the tumor; according to the contour length and wrapping length, calculating the wrapping degree of the tumor-wrapping vessel. By the arrangement, wrapping degree of the tumor-wrapping tumor is determined.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a method and a device for determining the degree of tumor-encircled blood vessels. Background technique [0002] Quickly, comprehensively and accurately diagnose common clinical tumors, and evaluate the relationship between the tumor and its surrounding blood vessels, especially to determine the degree of tumor surrounding blood vessels, which affects the feasibility of surgery and the impact of surgical methods. Selection and other aspects have a guiding role, and its clinical significance is very important, which largely affects the prognosis of the disease and the quality of life of patients after surgery. [0003] There is a good correlation between tumors and blood vessels. The important blood vessels pushed by the tumor mainly show two changes: one is the smooth displacement of blood vessels, and the outline of blood vessels is smooth and soft; the other is irregular ju...
