US 2026/0096857 A1 · METHOD FOR USING FIDUCIAL MARKER BY USING ANATOMICAL STRUCTURE IN SURGICAL NAVIGATION SYSTEM

Abstract

The present invention relates to a method for using a fiducial marker in a surgical navigation system, comprising: a computed tomography (CT) process step of obtaining a CT image through CT scanning of a patient; a CT image-based 3D reconstruction step of generating, on the basis of the CT image, a CT 3D model by using 3D reconstruction technology; a fluorescence process step of generating a fluorescent image by capturing, using a multi-camera, an anatomical landmark in which an anatomical structure near a surgical target of the patient is highlighted with a fluorescent contrast agent; a multi-camera-based 3D reconstruction step of generating a fluorescent 3D model from the fluorescent image by using the 3D reconstruction technology; and a registration step of registering the CT 3D model and the fluorescent 3D model into one model.

Dependent claims

A method of using a fiducial marker in a surgical navigation system, the method comprising:

a computed tomography (CT) process for obtaining a CT image via a CT scan of a patient;
CT image-based 3D reconstruction for generating, based on the CT image, a CT 3D model by using 3D reconstruction technology;
a fluorescence process for generating a fluorescent image by capturing, using multiple cameras, an image of an anatomical landmark in which an anatomical structure near a surgical target of the patient is highlighted with a fluorescent contrast agent;
multi-camera-based 3D reconstruction for generating a fluorescent 3D model from the fluorescent image by using 3D reconstruction technology;
and
registration for registering the CT 3D model and the fluorescent 3D model into one model.
