摘要： An x-ray computed tomography apparatus has a stationary unit and a rotatable unit, carrying an x-ray source and a radiation detector. The rotatable unit rotates around an axis relative to the stationary unit, that proceeds through both units. In order to transmit signals and measured data between the rotating unit and the stationary unit, transmitting/reception devices are mounted at each unit. The transmitting/reception devices transmit directed signals and are automatically oriented toward each other during relative movement caused by rotation of the rotating unit with respect to the stationary unit.

摘要： In a device for contact-free transmission of electrical signals between two gantry parts of a computed tomography system that rotate relative to one another, at least one annular, circumferential transmitter element is mounted on one gantry part to transmit the electrical signals, and at least one receiver element to receive the signals emitted by the transmitter element is mounted on the other gantry part . The transmitter element is formed by a single conductor running on a surface, this conductor representing an electrical reference ground (zero potential). At least one dielectric immediately follows on the surface, and multiple conductive conductor structure pairs are executed in two mirror-image parts and are mounted on the at least one dielectric. The separation of conductor structures arranged at the edge from the edge of the surface of the reference ground has a magnitude that both amounts to at least 10 mm and corresponds to at least half of the distance from the two conductor structures arranged in a mirror image at the edge, to the nearest conductor structure.

摘要： A focus-detector arrangement of an X-ray apparatus is disclosed for generating projective or tomographic phase contrast recordings with a phase grating. According to at least one embodiment of the invention, in the gaps between its bars, the phase grating includes a filler material whose linear attenuation coefficient in the relevant energy range is greater than that of the bars. The height of the filler material in the gaps is dimensioned on the one hand so that the X-radiation with the energy used for measuring the phase shift generates a phase shift in the X-radiation such that, after the phase grating, the rays which pass through the bars are phase shifted by one half wavelength relative to the rays which pass through the gaps with the filler material. Further, the height of the filler material in the gaps on the other hand is dimensioned so that the attenuation of the X-radiation, at least in relation to the energy used for measuring the phase shift, is the same when passing through the bars and when passing through the filler material.

摘要： An x-ray absorption grid produced by a lithography method for use in a phase-contrast CT system has at least two individual grids arranged atop one another in the radiation direction. Each individual grid has a grid area with a grid structure including grid webs and grid gaps in alternation. Each individual grid has a region outside of the grid area (outer region). The outer region of the at least two individual grids has toothed structures corresponding to one another at least two points. The toothed structures are generated as well in the production of the grid structure. The toothed structures have a position that is defined relative to the grid structure, such that a defined alignment of the individual grids occurs given a combination of the individual grids by engagement of the toothed structures of individual grids lying atop one another.

摘要： A system includes exactly one rotary frame for holding at least one x-ray tube, and one radiation detector that is situated opposite, the x-ray tube being equipped with a diaphragm that can be dynamically adjusted. The system includes a first operating mode for imaging in which the x-ray tube radiate a ray fan of constant fan angle onto the oppositely situated detector, and CT image data records are calculated from the measured data of the detector. It includes a second operating mode for irradiation in which by using at least one imaging x-ray tube used in the first operating mode radiates an x-ray fan that varies with reference to alignment during the rotation of the rotary frame, is narrower perpendicular to the system axis, and remains aligned with the site of at least one tumor in the patient independently of the angular position of the rotary frame.

摘要： In a signal transmission device as well as a method for transmission of signals between two elements moving relative to one another, in particular for transfer of measurement and/or control data between a rotating part and a stationary part of a computed tomography apparatus, a transmission device with an RF strip conductor is used on a first of the two elements, the RF strip conductor is composed of a dielectric layer with electro-optical properties between two strips made of an electrically-conductive material, into which the signals are fed. In the method and the associated device, local temporal changes of optical properties of the dielectric layer that are electrically induced in the dielectric layer by the signals proceeding along the strip conductor are scanned with a light beam of a scanning unit arranged on the second element, at least during a movement segment of the relative movement of the two elements. The signal transmission device and associated method enable signal transmission with a high data rate.

摘要： A device for generation of x-ray radiation has one or more cold electron sources as a cathode and at least one x-ray target as an anode that are arranged in an evacuable housing. Upon application of an electrical voltage between cathode and anode, electrons emitted from the electron source are accelerated in an electron beam onto the x-ray target. A device for reduction of the proportion of positive ions in the region of the electron source is arranged between the electron source and the x-ray target in the housing. The device exhibits a long lifespan with good focusing capability and fast modulation capability of the electron beam.
