20090062902 | Stent for positioning in a body conduit or method for producing this stent - 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. | 03-05-2009 |
20090092230 | DETECTOR HOLDER, X-RAY SYSTEM AND X-RAY FLAT DETECTOR - 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. | 04-09-2009 |
20090296881 | APPARATUS AND METHOD FOR A MEDICAL DIAGNOSIS - In a method and an apparatus for medical imaging, the radiation source is aligned relative to a detector plate, and the alignment is controlled so that the high-energy being emitted the radiation source always strikes the detector plate with a symmetrical distribution relative to a central ray of the radiation source. | 12-03-2009 |
20100097229 | METHOD FOR MONITORING THE POWER STATE OF AN X-RAY EMITTER AND/OR AN X-RAY DETECTOR, AND SYSTEM FOR CARRYING OUT SAID METHOD - In a method and system for monitoring the power state of an x-ray emitter and/or an x-ray detector, the x-ray emitter is operated according to a set of test parameters, so as to emit x-rays that strike at least a portion of the detector region of the x-ray detector. At least one value characterizing the operation of the x-ray emitter and/or the x-ray detector is determined, and this detected parameter is compared with a comparable reference parameter value. The power state of the x-ray emitter and/or the x-ray detector is determined based on deviation of the detected parameter from the reference parameter. | 04-22-2010 |
20110004347 | MEDICAL RADIOLOGICAL DEVICE AND RADIOLOGICAL SYSTEM - 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. | 01-06-2011 |
20110087062 | MINIATURE X-RAY TUBE FOR A CATHETER - 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. | 04-14-2011 |
