Device for the investigation periodontal diseases and image processing program, which the device used for the investigation of periodontal diseases

摘要

The device for the investigation of periodontal diseases of the present invention is characterized in that it is a ct - x-ray device, the teeth, the gum and the alveolar bone, in an oral cavity comprehensive parts of the body and volume data of these parts of the body is produced, a has area-setting means, on the basis of a volume data with the tooth to be examined area, which is in communication is established, a determining means, the the main axis of the tooth to be examined is determined, a correcting means, the the coherent area so that the main axis of the tooth to be examined with the direction of the normal of the sectional view of the ct - x-ray image, a multiplanar - reconstruction picture is - generating means, which is a multi planar reconstruction picture examples of the corrected coherent area is produced, a generating means for, for example, a folded imaging, the coordinates of conversion of the coherent area and an unfolded image and a rotary image is produced, and navigation means which, on the corresponding relation of the spatial coordinates between the planar reconstruction picture is, of the folded image and the live image, comprises.
