There is provided a three-dimensional image reconstructing apparatus for reconstructing a three-dimensional image of an object. The three-dimensional image reconstructing apparatus includes an image-capturing section that captures a plurality of transmission-type images each of which is represented by densities of different levels, a characteristic region selecting section that selects a plurality of characteristic regions in each of the transmission-type images, a characteristic region distribution calculating section that calculates a spatial distribution of the characteristic regions based on respective positions of the characteristic regions, in each of the transmission-type images, and a three-dimensional image reconstructing section that, when reconstructing the three-dimensional image which shows the three-dimensional structure of the object and in which the densities of different levels are allocated to the whole object by integrating the transmission-type images, allocates the densities of different levels of the transmission-type images to respective positions, in the three-dimensional image, of the characteristic regions based on the spatial distribution of the characteristic regions, so as to reconstruct the three-dimensional image in which a three-dimensional structure in each of the characteristic regions is shown.
