<P>PROBLEM TO BE SOLVED: To obtain three-dimensional image data for producing an artificial bone by a small number of times of irradiation of a small X-ray dose. <P>SOLUTION: A photographing position discrimination means 18 discriminates photographing position data of an X-ray tomographic means 12, and the photographing position data storage means 19 stores photographing position data. Based on image data obtained by a high energy image detection means 20 and that obtained by a low energy image detection means 21, a bone section tissue image data production means 22 superposes both of the pieces of image data to produce bone section tissue image data where a bone section tissue is extracted. An image data storage means 23 stores the bone section tissue image data. An image processing means 24 produces the three-dimensional image data for producing the artificial bone which is image data of a large number of tomographic planes and which can be or is made to be three-dimensional based on the photographing position data from the photographing position data storage means 19 and the image data from the image data storage means 23. <P>COPYRIGHT: (C)2007,JPO&INPIT |
