Forming an arrangement of two ceramic barrier layers () on a polymeric substrate () includes the steps of applying a first ceramic barrier layer () on the substrate (). The surface (A) of the first barrier layer () is modified to introduce new nucleation sites on the surface of the first layer. A second ceramic barrier layer () is formed on the first barrier layer () using the new nucleation sites. The second ceramic barrier layer is deposited with independent nucleation sites such that a barrier stack of enhanced quality is formed.

A method is disclosed for imaging within the scope of a radiation therapy. In at least one embodiment, the method includes preparing one or more contrast agent-enhanced x-ray image data records; and using the contrast agent-enhanced x-ray image data record during an irradiation planning and/or during an irradiation session.

A patient bed for an imaging medical apparatus has a patient support plate that has at least one radar antenna to obtain physiological and/or geometric data from a patient the patient support plate. In a method for the operation of such a patient bed having at least one radar antenna in an imaging medical apparatus, the at least one radar antenna is operated to obtain data from the patient on the patient support plate.

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.

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&#xb0;. 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.

A radiation transducer has a luminophore layer applied on a substrate, and at least one anti-discoloration substance is applied on the luminophore layer. In a method to produce a radiation transducer a luminophore layer is applied on a substrate, and at least one anti-discoloration substance is applied on the luminophore layer after the application of the luminophore layer on the substrate.

A field emission cathode has a field emitter and an extraction grid, and the field emitter and the extraction grid can be moved relative to one another. Such a field emission cathode is highly durable and exhibits a longer lifespan. An x-ray tube has a field emission cathode composed of a field emitter and an extraction grid that can be moved relative to one another. Such an x-ray tube is highly durable and exhibits a longer lifespan.

Field emission cathode and x-ray tube embodying same

An x-ray tube has a cathode that generates free electrons; an anode on which the free and accelerated electrons strikes so that x-ray radiation is generated; a cooling channel with coolant flowing therethrough to cool the anode; a vacuum region between the cathode and the anode; and an exit window through which the x-ray radiation exits from the x-ray tube. The anode is fashioned as a transmission anode; with the transmission anode arranged between the vacuum region and the cooling channel, with the cooling channel arranged between the transmission anode and the exit window; so the useful x-ray radiation passes through the coolant.

An x-ray converter element has an x-ray-permeable and moisture-impermeable substrate, an x-ray-permeable carrier that is connected to the substrate, and a scintillator that is applied on the substrate, and an optically-transparent and moisture-impermeable protective layer that covers the scintillator.

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.

A computer tomography system has a stationary x-ray tube, that has an anode ring and at least one cathode ring, that extends through 360&#xb0; in a system plane perpendicular to a system axis, and a vacuum region that is at least partially delimited by a light-permeable and/or infrared-permeable vacuum window is provided between the anode ring and the at least one cathode ring. A support frame is rotatable around the system axis parallel to the system plane, on which are arranged, in at least one angle position, a system with at least one laser for local activation of electron emission at the at least one cathode ring, and a filter and/or collimator set, and a radiation detector opposite the filter and collimator set.

A method is described for large-area application of at least two, for example, electroluminescent layers onto a substrate. In a process step A), spacer () is structured on the transparent substrate in such a way that, upon application of a second functional layer (), contact between a first functional layer () already applied on the substrate and a part of a printing machine responsible for the transfer of the functional layers onto the substrate is avoided. In two other process steps B) and C), the first functional layer () and the second functional layer () are applied over a large area, for example, through large-area standard printing methods.
