Patent ID: 11090014

Abstract:
In an image processing device (300), a position determiner (313) determines, in a three-dimensional image showing an upper jaw part of a subject and a lower jaw part of the subject, positions of left and right mental foramina of the lower jaw part and a position of an incisors tube of the upper jaw part. A coordinate system setter (314) sets a three-dimensional coordinate system having an origin at a position established by the positions of the left and right mental foramina and the position of the incisors tube that are determined by the position determiner (313), the three-dimensional coordinate system including: a first coordinate axis that passes through the origin and the position of the incisors tube; a second coordinate axis that is perpendicular to the first coordinate axis and a straight line connecting the position of the left mental foramen and the position of the right mental foramen; and a third coordinate axis that is perpendicular to the first coordinate axis and the second coordinate axis.
