SURGICAL NAVIGATION SYSTEM USING IMAGE SEGMENTATION

摘要

A system for tracking a piece of medical equipment intraoperatively using a collinear array of fiducial markers positioned at known fixed distances relative to each other on the medical equipment and a camera capturing an image on a single image plane. Representations of the fiducial markers are segmented from a captured image, 3D orientation and position of the medical equipment are calculated using the segmented representations, and the orientation and position of the medical equipment are tracked relative to the camera. The orientation and position of the medical equipment may be registered within a 3D virtual space. The system may be used as part of a surgical navigation system.
