Abstract
Conventional X-ray photographing has several problems for eliminating the influence from the cervical vertebrae such as rework of original images, causing possible loss of useful information, as well as long processing time and the need for a plurality of panoramic images. The X-ray photographic device according to the present invention can eliminate the influence from the cervical vertebrae projected at around the anterior teeth of the panoramic image of a tooth row, without missing the original image information and without influence of different shapes of cervical vertebrae and X-ray permeability by each subject. In addition, as the present invention achieves these through arithmetic processing, there is no need to intensify X-ray output in the section corresponding to the anterior teeth, nor decelerate the rotating speed of arms during photographing, and it is possible to suppress the X-ray dose received by the subject.
