Combining reconstructed images by weighted addition

摘要

The invention relates to a method of and an X-ray device for forming a 3D image (B) of an object (13) to be examined by combining at least two reconstruction images (S1, S2) by weighted addition, said reconstruction images being acquired notably by means of an X-ray device (1) and each reconstruction image (S1, S2) being weighted by a respective weighting function (A1, A2) that describes at least approximately the distribution of noise and/or artefacts in the relevant reconstruction image. The image quality of the resultant 3D image is thus significantly enhanced.
