Computer simulation of an intraoral radiography using perspective projection of CT data

Though the intraoral radiography is most frequently and widely used in clinical dentistry, this method is very special comparing with other extraoral radiography for jaw bones. The radiographer must consider a lot of factors, such as, the anatomical form of maxilla or mandible unique to each patient, direction and size of the tooth, the position of the film, and the position and angle of the cone-head. It is not easy to master this technique because of these factors associated with this technique. Computer-assisted training system may be useful to learn the effects of these factors on the radiograph. The purpose of this study was to develop a computer simulation system for intraoral radiography by a projection from point focus using the three dimensional data of the head with CT scanner.
