Abstract

The method involves generating a series of two-dimensional projection photos of the region to be investigated, where each projection includes a portion of the x-ray positive marks (15) of phantoms (14). The position of the marks is determined from the photos, with which reference positions of the marks are compared. Each of the projection images is transformed such that the sum of deviation amount between the positions of the marks is determined and is transformed to a 2-dimensional data set. The volume reconstruction is executed with the transformed 2-dimensional data set.
