Generative Model of CT-to-Vessel Structure

Abstract (in Japanese) (See Japanese page) 
(in English) 3D vascular centerline extraction from CT images is an important task for vascular structural analysis and surgical planning. Therefore, automating vascular extraction is desirable, and in recent years several deep-learning-based methods have been proposed to estimate vascular centerlines. However, because these are deterministic models, they are likely to produce anatomically unnatural centerlines. In this study, we propose a diffusion model for estimating vascular centerlines from 3D CT images. Evaluation on a public CT dataset showed that the proposed method achieved higher extraction accuracy and produced more anatomically natural vascular structures than conventional methods.
