Abstract
It is an object of the present invention to acquire 3-dimensional image data that correctly express a structural configuration of the subject by processing the projected image data obtained by projecting the subject toward the plural angles . A shape computing unit 260 calculates shape data which represent a outline of the subject, using a plurality of 1st image data of the subject obtained by projecting the subject toward the plural angles. A distributing unit 220 generates gray-scale density-distributions by spreading and distributing densities shown in gray-scale image of the subject respectively within angles along which said gray-scale image was captured. A second integrating unit 240 generates 3-dimensional gray-scale data, which expresses the subject with the 3-dimensional image data, by integrating a plurality of said gray-scale density-distributions generated from a plurality of gray-scale image captured from a plurality of angles. A first integrating unit 280 integrates the shape data and 3-dimensional gray-scale image. A data processing unit 300 generates 3-dimensional image data by extracting only density that exists in perimeter of a shape that the shape data represent…
