Abstract: A mobile X-ray apparatus for medical examination includes an apparatus for producing X-ray images having a digital Radiography detector positioned at a first spatial position, an X-ray tube assembly positionable at a second spatial position relative to the first spatial position, sensor(s) for providing the first spatial position and/or the second spatial position, a control unit for receiving the first and/or the second spatial position(s) from the at least one sensor and for controlling the first or second spatial position for alignment of the X-ray tube assembly with the detector based on the first and second spatial positions, a drive wheel, a base, optionally an elevating column, and a telescopic arm which is rotatable into a direction perpendicular to a driving direction of the base. The apparatus is controllable to drive along a patient table and/or the X-ray tube assembly is height adjustable in front of a wall stand, for alignment.

Abstract: An elevating column for an X-ray apparatus, the X-ray apparatus preferably being mobile, wherein the column is rotationally fixed in relation to a base of the X ray apparatus, and the column having a plurality of segments, including: a first segment, having a first end and an opposite second end, arranged at the base with the first end, and a second segment having a first end and an opposite second end; wherein the second segment is arranged at its first end with an overlap of the first segment's second end and is moveable relative the first segment; and a first elevation adjustment unit including: at least a first threaded elongate member fixed at one of the first and second segments, and a first threaded receiving element arranged at the other of the first and second segments, matingly engaged with the threaded elongate member for elevation adjustment of said column.
