Positioning apparatus and method for transversal dental x-ray tomography |
摘要 |
An apparatus and method used in dental transversal x-ray tomography provides off-line alignment of the patient denture impression with the bite block of a panoramic x-ray equipment, and allows accurate and reproducible patient positioning during the imaging process. An impression of the patient denture is taken on a special tray. The tray is mounted on the alignment apparatus and is aligned by using optical marking in correspondence with the target zone. The alignment apparatus is then mounted on a panoramic x-ray equipment, and the patient is invited to bite on the tray during the imaging process.
