The invention discloses a
periodontal disease CBCT
longitudinal data recording and analyzing method. A
cone beam CT machine is used for obtaining three-dimensional volume data of an
oral cavity patient, data three-dimensional space correction is carried out, because CBCT data shooting angles are different, shooting machines are different, and imaging results are different; normalizing is carried out on the image processed in the second step or correction is carried out on a gray value of the image;
disease prediction is carried out on new
patient information, and then a corresponding image report can be written manually or automatically. According to the scheme,
data acquisition at different moments is carried out; the three-dimensional space correcting is carried out on the same tissue ofthe data at different moments in the same coordinate
system; a common anatomical mark point or mark position is determined for accurate registration, gray value normalization, and image region segmentation is realized (region-of-interest segmentation), progress factors of periodontal diseases are analyzed in combination with clinical
electronic medical record information, information difference between longitudinal
time series data is analyzed, and a suggested diagnosis and treatment scheme is provided.
