The authors have been developing a surgical navigation system for the graft replacement in the thoracoabdominal area. The system supports a surgeon to detect an essential artery, which provides major blood supply to the spinal cord. With a self-produced viewer, we could assist for surgeons to visualize a virtual tool on the three-dimensional image space in sync with the movement of the current position of a pointer tool. In this paper, we describe the training session with a human phantom assuming the clinical case. We newly implemented an adjusting method in the regional area and examined the effectiveness of the system. It was found that the accuracy of the system is enough to utilize for clinical application.
