Image processing program used for periodontal disease examination apparatus and periodontal disease examination apparatus

摘要

In the periodontal disease testing apparatus of the present invention,An X-ray CT apparatus for photographing a part including the teeth, the gingiva and the alveolar bone in the oral cavity to generate volume data of the part,An area setting unit that sets a related area of the inspection target tooth based on the volume data;A defining means for defining a main axis of the inspection target tooth,Correction means for correcting the relevant region such that the main axis of the inspection target tooth coincides with the normal direction of the cross section of the X-ray CT image,Multi-sectional reconstructed image generating means for generating a multi-sectional reconstructed image of the corrected relevant region,A developed image or the like generating means for generating a developed image and a rotated image by carrying out coordinate transformation on the relevant region,Navigation means for indicating a correspondence relationship of spatial coordinates between the multi-sectional reconstructed image, the developed image and the rotated image,In order to improve the quality of the image.
