Abstract

The invention provides a liver image segmentation quality evaluation method and device and computer equipment. Inputting the acquired liver CT sequence diagram into an image segmentation model; obtaining a blood vessel mask and a liver mask contained in each liver CT image; carrying out connected domain analysis on each blood vessel mask; utilizing the obtained blood vessel connected domain; veinregions contained in the blood vessel masks are determined; and obtaining and outputting a liver blood vessel segmentation quality evaluation result of the liver CT sequence diagram acquired this timeby utilizing the determined liver mask and vein region. The medical personnel are informed of the liver blood vessel segmentation quality of the liver CT sequence diagram; therefore, it is avoided that under the condition that the liver blood vessel segmentation quality of the liver CT sequence diagram is poor, medical staff continue to refer to the liver CT sequence diagram to diagnose and treata patient, and the auxiliary effect of the liver auxiliary diagnosis system on liver disease diagnosis and surgical treatment is greatly improved.

Description

technical field [0001] The present application mainly relates to the technical field of image processing, and more specifically relates to a liver image segmentation quality assessment method, device and computer equipment. Background technique [0002] The Liver Assisted Diagnosis System is designed to be a form of implementation of the hierarchical diagnosis and treatment system. By deploying in grassroots hospitals, it can reduce the misdiagnosis rate of tumors and assist liver interventional surgery while realizing the first diagnosis at the grassroots level and relieving the pressure of medical treatment in large hospitals. [0003] Among them, in order to effectively control the amount of bleeding during liver resection and ensure the integrity of the inflow and outflow of blood vessels after surgery, it is usually to analyze computed tomography (CT) images and segment the blood vessels it contains. Positioning and three-dimensional visual display to assist the diagnos...
