| Research Abstract |
A surgical navigation system for aortic vascular surgery have been developed and applied in clinical trials. Through our early experience, the system needed to improve the usability and the reliability. Especially, in registration process, it was an inevitable issue to reduce errors based on human factors. Projections of the bone under skin were manually selected as registration points before the incision. Errors caused by human factors, such as the surgical position and as the tissue thickness, were estimated and correction methods were examined. Besides, the combination points on the internal and surface body were utilized for registration after the thoracotomy to adjust a target artery. It was concluded that the renewed system could be easily set up and would be helpful to detect the target artery.
