Abstract: The present invention relates to monoscopic and stereoscopic X-ray viewing. In order to provide an improved fluent work flow for X-ray viewing with an improved visual perception of depth information, it is provided to generate an electron beam from a cathode arrangement towards a target area of an anode; to deflect the electron beam such that the electron beam hits the anode at different target spots (94a, 94b), wherein the variation is provided as gradual variation of an impinging direction of the electrons such that a stepless transition between monoscopic and stereoscopic viewing is provided. In the monoscopic viewing, X-ray radiation is generated from a single focal spot position, and wherein in the stereoscopic viewing, X-ray radiation is generated from two focal spot positions spaced apart from each other in a first stereo-direction transverse to a viewing direction (92). It is further provided to generate X-ray radiation by the electron beam impinging on the target area, wherein the X-ray radiation is provided with different focal spots for monoscopic and stereoscopic X-ray imaging. Still further it is provided to display or otherwise provide image data of the object with a gradual transition between monoscopic and stereoscopic viewing.

Abstract: A wavelength-classifying type X-ray diffraction device bombards a sample with characteristic X-rays generated from an X-ray generation source, and detects characteristic X-rays diffracted by the sample using an X-ray detector. The X-ray generation source is composed of several metals of different atomic number, respective metals generating several characteristic X-rays of different wavelengths. An X-ray detector is composed of several pixels for receiving X-rays and outputting pulse signals corresponding to X-ray wavelengths. Pixels are respectively furnished with classification circuits. The classification circuits classify and output pixel output signals based on each of characteristic X-ray wavelengths. X-ray intensity is detected on a per-wavelength basis in individual pixels 12. Measurement data based on different wavelength X-rays are acquired simultaneously in just one measurement. Data of diffracted X-rays of different wavelengths are acquired using the entire region of the receiving surface of a two-dimensional detector.

Abstract: An x-ray arrangement includes a vacuum container in, which a rotary anode and a rotor of an electrical machine are disposed. The rotary anode and the rotor have a torque-proof connection to one another and are rotatably supported in the vacuum container, so that the rotary anode and the rotor are rotatable around an axis of rotation. Viewed in a direction of the axis of rotation, a laminated stator core is disposed in an area of the rotor. The area of the rotor, in relation to the axis of rotation, surrounds the vacuum container radially outwards. A stator winding system is disposed in the laminated stator core. The stator winding system has windings embodied as a yoke winding.

Abstract: An x-ray tube target and method of repairing a damaged x-ray tube target. The x-ray tube target includes an original substrate and a portion of the original substrate that includes a new portion of a substrate and a new target track that is attached to a void in the original substrate. The method includes removal and replacement of damaged materials on used anode targets of x-ray tubes, thereby enabling recovery of used anode targets without the use of expensive and time consuming layer deposition methods. The method also avoids the high costs and long development cycles associated with known repair and refabrication methods for anode targets of x-ray tubes.

Abstract: A computed tomography apparatus (10) includes spaced radiation sources (82, 84), such as anodes, which each propagate a cone-beam of radiation (40, 50) into an examination region (14). A detector (22) detects radiation which has passed through the examination region. An attenuation system (55) interposed between the radiation sources and the examination region for cone-angle dependent filtering of the cone beams. The attenuation system allows rays which contribute little to a reconstructed image to be attenuated more than rays which contribute more.
