Abstract
Recently, ultrasound diagnostic machine has become a high system versatility at low cost, but ultrasound image and the patient's response is confusing. To solve this problem, studies of medical system for imparting information to the physician using augmented reality technology has been widely performed. However, many of problems in the tracking method, the system does not operate stably. Therefore, we have proposed a system for place the magnetic and optical TrackPoint anywhere as a relay, and so the optical markers appear reliably, interpolating between the TrackPoint and the probe in a magnetic tracking. Moreover, in order to measure the usefulness, enumerate and classify medical system that can be considered, and performing quantitative evaluation of stability and system accuracy.
