Haptization of Multimodal Dental Images
"In the field of dentistry, an integrated display environment of a 3D dental cast and panoramic radiography can provide a clear understanding of the patient's dental condition. Not only visual but also haptic display appears to be effective in order to present an integrated image. This research proposes a cross-reference system that enables users to indicate a point on the main image and obtain additional information from the other image through haptic feedback. In the proposed method, a virtual panoramic image created from a 3D dental cast and a real panoramic image are registrated based on the dental contour to obtain integrated multimodal images. The proposed method was evaluated using manually collected points in each image. The results indicated that a registration error of 1.4 mm was acceptable for obtaining a sufficiently clear understanding of the dental condition. Furthermore, vibrotactile and haptic sensation could be presented according to the interior and the shape information of the dental image."
