 Recently, navigation system has found a wide acceptance in various surgical fields. However, in the field of laparoscopic surgery, because of large deformations between preoperative images and organs confirmed during the operation, clinical application of navigation system is difficult. Moreover, the restricted views and the lack of tactile sensation in laparoscopic surgery restricts the surgeon's ability and thus makes the surgeon stressful. More informations that could be used by the surgeons during the operation are necessary. We have newly developed an augmented reality(AR)navigation system which integrates the images by using an accurate three dimensional sensory system that can be utilized in laparoscopic surgery. Augmented reality visualization, which superimposes the visualized pre/intra-operative 3 D images onto captured laparoscopic live images was achieved and displayed on the monitor. The overlayed 3 D images were quickly updated and reconstructed, followed by the real laparoscopic images. We have preliminary established a'combined'AR navigation system and applied it to various clinical cases.
