Abstract

Method and device for forming a 3D image of an object to be examined by combining at least two reconstruction images, acquired by an X-ray device, by weighted addition. Specifically, each reconstruction image is weighted with a respective weighting function which describes at least approximately the distribution of noise and/or the distribution of artifacts in the reconstruction image. The image quality of the resultant three-dimensional image is thus significantly improved.
