摘要： By a contrast means contained in an inventive stent which has a greater permeability for x-radiation features than the body tissue surrounding the stent in a relevant body conduit, this stent can be clearly detected in its position on an x-ray image of the relevant body conduit while at the same time exhibiting good biological compatibility; a gas, especially one contained in cavities of the stent is provided as a contrast means. The inventive production method for this stent with the aid of a catheter embodied specially for the purpose enables the production of the stent from a malleable polymer mass in the relevant body conduit so that the stent is adapted especially precisely to the shape of the relevant body conduit.

摘要： A detector holder for a flat panel x-ray detector has a mechanical plug interface that allows flat panel x-ray detectors of respectively different types to be connected to and held by the detector holder. An x-ray system equipped with such a detector holder can be used flexibly for different applications respectively requiring different types of flat panel x-ray detectors. The type of the flat panel x-ray detector currently retained by the detector holder can be automatically detected and used by the data processor that processed output signals from the currently-employed flat panel x-ray detector.

摘要： For the purpose of noise correction for an x-ray flat-panel detector (2) it is firstly provided that in the dark image—without radiation impinging on the detector panel (4)—the noise is recorded for the subareas of an active area (8) and from this, subarea-specific correction factors are determined by means of which the respective signal value of the respective subarea is corrected in imaging operation. A dark area correction factor (DF1, DF2) is also determined in each case from the noise of two dark areas (6) that are spaced apart with respect to each other. In order to determine subarea-specific signal correction factors (SK), each of the DA correction factors (DF1, DF2) is weighted with a subarea-specific weighting factor (g1, g2), in particular a distance factor (a). By means of said measure improved noise correction is achieved.

摘要： A plurality of plates is bonded together by butting in order to manufacture a flat-plate x-ray detector. The butting determines artifacts in x-ray images taken with the flat-plate x-ray detector. According to the invention the butting structure is first measured in the flat-plate x-ray detector and a pixel quantity parameter is determined for an interpolation, whereby said parameter can be small for a narrow butting structure and large for a wide butting structure. Accordingly an interpolation of pixel data in x-ray images which have been taken is performed on the basis of the pixel quantity parameter, preferably by row or by column.

摘要： A medical radiological system has a radiological device with at least one element that can be electrically adjusted in order to allow an adaptation of the radiological device to body dimensions of a patient to be examined. The radiological device has a controller with an interface that receives a patient parameter set from a computer, with which patient data are processed and stored. The controller calculates a desired position of the element from the received patient data set, and automatically controls positioning of the element by electrically adjusting the element to the desired position.

摘要： For noise correction in connection with a flat-panel x-ray detector (2), noise signals of a dark area (6) are checked for deviations exceeding a specified threshold (g) which, if any are present, will be taken into consideration separately for calculating the correction factor derived from the noise signal. Image artifacts due, for example, to high-contrast objects such as, for instance, cardiac pacemakers or metallic implants, in the x-ray image will be avoided through this measure.

摘要： A miniature X-ray tube for intravascular or intracorporeal radiation treatment in living beings is proposed. The X-ray tube comprises a cylindrical housing section with a longitudinal axis. The miniature X-ray tube also comprises a cylindrical or cylindrical-tube-shaped first field emission cathode arranged concentrically about the longitudinal axis in the housing with a plurality of carbon nanotubes which emit electrons radially outward. The miniature X-ray tube also comprises a second field emission cathode in the housing with a plurality of carbon nanotubes which emit electrons in the direction of longitudinal axis. The miniature X-ray tube only emits little heat and is robust against mechanical stresses.

摘要： In order to determine the quality of a butting during the manufacture of a flat X-ray detector, it is sufficient for the mounting plate of the detector to be produced with detector plates which are connected by butting, and for a backlight board to be provided in order to illuminate the pleats through the mounting substrate. At least one backlight image is recorded with the aid of the backlight board and the detector plates, and is evaluated automatically in order to determine whether, in the zone of the image of the butting structure, it has areas which are illuminated more than averagely strongly or weakly, based on a predetermined assessment criterion. This may result in the determination of artifacts, which are characterized by the so-called light-and-shadow effect. It is thus possible to determine during manufacture whether the butting is sufficiently good to continue the detector manufacturing process, or not.
