Abstract
A reconstruction process for processing pixel data for tomographic volume image data uses a concise reconstruction algorithm based on an assumption that an axis of X-ray emission axis always exists on a plane orthogonal to an axis of revolution of an X-ray tube and an FPD. In time of the reconstruction process, a corrected parameter is applied to the reconstruction algorithm for correcting a mechanical displacement occurring between the axis of revolution of the X-ray tube and FPD and the axis of X-ray emission. Thus, errors due to the mechanical displacement may be avoided by a simple data processing of setting the corrected parameter to the reconstruction algorithm, without impairing lightness of a data processing load on the reconstruction algorithm.
