摘要： A flat organic photodetector has a structured first electrode that forms several sub-electrodes, a second electrode, at least one first organic layer, and a second organic layer. The organic layers are situated between the two electrodes and are structured in conformity with the structuring of the first electrode, so that the two organic layers are subdivided into multiple active regions respectively corresponding to the sub-electrodes of the first electrode. An x-ray detector has such a flat organic photodetector and an x-ray absorbing layer applied thereon.

摘要： The invention provides an improved method for polish-etching of silicon carbide, which is arranged in series with an electrolyte and a metallic counter-electrode in a current circuit with an adjustable direct voltage, wherein an alkaline solution is used as the electrolyte, preferably in a high concentration and at great current density. In this way, uniform removal of the material and an even surface are obtained.

摘要： Bei der Erfindung handelt es sich um eine Spannstation zum Einstellen der mechanischen Spannung eines Abdeckbandes (2), umfassend eine Ankereinheit (10), dazu ausgelegt in einem ebenen Gebäudeteil (5) versenkbar befestigt zu werden, sowie weiterhin umfassend wenigstens eine Federeinheit (16), dazu ausgelegt mit der Ankereinheit (10) sowie mit einem ersten Ende des Abdeckbandes (2) verbunden zu werden, wobei die Federeinheit (16) derart elastisch ausgebildet ist, dass sie zum Einstellen der mechanischen Spannung des an einem zweiten Ende befestigten Abdeckbandes (2) ausgelegt ist. Die Erfinder haben erkennt, dass die Verwendung einer elastischen Federeinheit (16) das Einstellen der mechanischen Spannung des Abdeckbandes (2) erheblich erleichtert. Die jeweils gewünschte Spannung kann einfach durch die Wahl der entsprechenden Elastizität der Federeinheit (16) eingestellt werden. Weiterhin kompensiert eine elastische Federeinheit (16) abrupte Spannungsänderungen, so dass eine Beschädigung oder gar ein Riss des Abdeckbandes (2) vermieden wird.

摘要： An x-ray computed tomography apparatus has one anode ring in a vacuum housing surrounding an examination volume, wherein a focus of an x-ray source revolves on the anode ring to expose the examination volume with an x-ray beam from different directions, and a detector system arranged on a rotating frame that can rotate around a system axis. The detector system serves to detect the x-ray radiation exiting from the examination volume, wherein the detector system and the focus can rotate around the system axis synchronously and in the same rotation direction with a rotation angle offset by 180°. The apparatus also includes a computer to process the measurement values acquired by the detector system. The anode ring can be driven such that it rotates around the system axis, and the rotation direction of the anode ring and the rotation direction of the focus around the system axis are opposite while a rotation of the focus around the system axis ensues.

摘要： An x-ray detector has a scintillator that emits light in response to exposure to x-ray radiation, and an activatable photosensor that detects the light from the scintillator. While the scintillator is being irradiated with x-ray radiation, the photosensor is inhibited from detecting the light for a predetermined time interval. After the irradiation of the scintillator with x-ray radiation ends, only then is the photosensor activated to detect light from the scintillator. An x-ray image of better quality is thereby obtained.

摘要： A radiation detector for detecting radiation has a semiconductor layer on a substrate, the semiconductor layer being covered by a converter layer so that incoming radiation penetrates the converter layer preceding the semiconductor layer. The semiconductor layer forms a part of a detector array formed by a number of detector elements. The semiconductor layer is given increased sensitivity by being formed of a polycrystalline semiconductor material.
