Abstract

A method for determining an alignment between at least two bone parts of an elongated bone system of a patient includes recording a plurality of partially spatially overlapping projection images by a recording system of an x-ray device during a translational movement of the x-ray device or the recording system in a direction of or parallel to a longitudinal axis of the bone system. Tomosynthesis image data of the bone parts is reconstructed from the recorded projection images, and an alignment angle between the at least two bone parts is determined or estimated at least partially based on the reconstructed tomosynthesis image data and/or the plurality of projection images.
