METHOD AND SYSTEM FOR ACQUIRING DSA-BASED MINIMALLY INVASIVE ABLATION ROAD

WIPO Patent Application WO/2023/236569

A1

The present invention relates to the technical field of image processing, and in particular, to a method and system for acquiring a DSA-based minimally invasive ablation road. The method comprises the steps of: acquiring a bottom-layer angiographic image of a target tissue before advancing a catheter and a real-time angiographic image after advancing the catheter; acquiring a real-time advancement road of the catheter in the target tissue according to the bottom-layer angiographic image and the real-time angiographic image; acquiring a temperature field and a thermal damage field of the target tissue after a thermal ablation starting signal is received; and acquiring a temperature field advancement roadmap containing temperature field information and a thermal damage advancement roadmap. By means of simulating a minimally invasive ablation procedure and image fusion, the present invention reduces the operation difficulty and the dependence on the experience of a surgeon.
