A method for creating a three-dimensional image information of a body part (16) that is larger than the field of view of an X-ray system (1), comprising the following steps: - arranging an X-ray source (4) and an X-ray detector (6) of the X-ray system (1) at a first Position such that the X-ray source (4) and the X-ray detector (6) can receive a first projection image of at least a first portion of the body part (16); - recording the first projection shot; Arranging the X-ray source (4) and the X-ray detector (6) at at least one second position such that the X-ray source (2) and the X-ray detector (6) can receive a second projection image of at least a second subregion of the body part (16), the second one Partial area partially overlaps the first partial area; and - reconstructing a three-dimensional volume of the body part (16) from a plurality of projection exposures; - Characterized in that - the positioning of the X-ray source (4) and the X-ray detector (6) takes place by a translational movement, so that the plurality of positions is on a straight line.
