Live augmented reality: a new visualization method for laparoscopic surgery using continuous volumetric computed tomography

摘要

Background Current laparoscopic images are rich in surface detail but lack information on deeper structures. This report presents a novel method for highlighting these structures during laparoscopic surgery using continuous multislice computed tomography (CT). This has resulted in a more accurate augmented reality (AR) approach, termed “live AR,” which merges three-dimensional (3D) anatomy from live low-dose intraoperative CT with live images from the laparoscope.
