Enhanced interactive surgical guidance using both preoperative and intraoperative imaging

摘要

Abstract: developed a technique called Interactive, Image-Guided Surgery (IIG) which tracks the position of a surgical instrument during surgery and displays that position on preoperatively- obtained tomograms. Recently we have incorporated real-time intra-operative video images: endoscopes and ultrasound into the data stream. The endoscope or ultrasound transducer's position may be tracked during surgery, allowing guidance and the correlation of intraoperatively perceived structures with preoperatively obtained tomograms.!8
