ABSTRACT:
In an X-ray apparatus for a computed tomography scanner, a plurality of combined X-ray tube segments are arranged round the central axis of the apparatus on which a subject to be examined is disposed. The X-ray tube segments each include a large number of electron beam generating means to produce an electron beam, a strip-like target having a surface against which the electron beam strikes and extending along a circular arc round the central axis, and an envelope containing these components. Along the surfaces of the X-ray tube segments facing the central axis lie a large number of X-ray detector elements to detect doses of fan-shaped X-ray beams emitted from the target and transmitted through the to-be-examined subject. The electron beam generating means successively produce electron beams, and fan-shaped X-ray beams are applied one after another to the subject from around the same.
