Abstract: A method for pre-soldering metal surfaces onto metallized substrates (1a, 1b), wherein solder preforms (2a, 2b) are placed onto the metal surfaces of the substrates (1a, 1b) or vice versa, after which the solder preforms (2a, 2b) are fused. To achieve a defined, consistent height of the solder layer, inhibit the formation of bulged solder, enable the production of even thicker solder layers of around 100 ?m with a thickness fluctuation of below 20 ?m to the edge of the solder layer and minimize a pore formation in the solder layer, a metallic gauze (3a, 3b) is pressed flat onto the solder preforms (2a, 2b) during the soldering or fusing processes, the metallic gauze (3a, 3b) consisting of a solder-wetting material.

Abstract: The invention relates to a method for producing a substrate comprising embedded conductive metal structures or metallizations, in particular for use as printed circuit boards. The aim of the invention is to allow the buried metallization of three-dimensional, i.e. curved or angular, substrates in addition to the two-dimensional flat and level, i.e. plate-shaped, substrates. According to the invention, this is achieved in that trenches and/or recesses are dug into the substrate using laser technology, and the metal structures are then produced in the trenches and/or recesses.

Abstract: A positioning device for positioning a load is provided. The positioning device includes a motor, a measuring device, and an evaluation device. The measuring device is associated with the motor, and is operable to ascertain measurement data that characterizes the motor current consumption by the motor in the positioning of the load. The evaluation device evaluates the measurement data that have been ascertained by the measuring device, so that in that way the loading of the positioning device by the load can be ascertained.

Abstract: A guidance system for a medical facility includes at least one floor element that extends along a path of the medical facility and is arranged in a floor area of the path. The at least one floor element is configured for magnetic interaction such that through the magnetic interaction of the floor element with a magnetic guide element arranged on a mobile transport device, a magnetic attraction is generated. The mobile transport device is guided along the at least one floor element by the generated magnetic attraction during forward motion of the mobile transport device along the path through the medical facility.

Abstract: The invention relates to a body made of ceramic materials, having a basic metallization made of at least one electrically conductive material, such as tungsten/glass or molybdenum/glass compounds and an adhesive, electrically conductive and corrosion-resistant coating. In order to improve energy losses, which is to say to increase the Q-factor, it is proposed that the coating comprises/carries at least one functional layer made of a metal or several metals, having lower specific electrical resistance than the electrically conductive material and the remaining constituents of the coating.

The system includes a radiation outlet of a radiation delivery and acceleration system from which a particle beam exits in order to interact with the patient positioned in an irradiation position; an imaging device for verifying the position of the volume to be irradiated in relation to the particle beam; and a patient-positioning device with which the patient can be brought into the irradiation position for irradiation. The imaging device checks the position of the volume to be irradiated in an imaging position of the patient that is spatially remote from the irradiation position, and the patient-positioning device automatically changes position between imaging position and irradiation position.

Abstract: The invention relates to a radiotherapy assembly comprising a particle emitter with an exit window for a fixed particle stream and a patient support device comprising a patient couch, which can be brought into an irradiation position that is suitable for irradiating a patient in front of the exit window. An X-ray diagnostic device determines or verifies the position of a tumor that is to be irradiated, said device comprising an X-ray source and a detector, which can be displaced in the area around the patient couch that has been placed in the irradiation position. The assembly permits the location of a tumor to be verified in the irradiation position, thus rendering a relocation of the patient unnecessary.

The patient positioning unit is designed in such a way that the patient can be brought in space into any desired body position in which the radiation therapy is also carried out. The CT gantry is arranged in a freely moveable fashion in such a way that imaging for the purpose of radiation therapy planning can be carried out in this body position of the patient.

Abstract: The invention relates to a method for generating a medical image with at least one emission source and at least one detector of a medical imaging system, with the radiation from the emission source penetrating the object and attenuated by the object being detected by the detector to generate the medical image as a mapping of the object structure. The invention also relates to a medical imaging system for the generation of image data as a basis for the generation of a medical image. By the provision of a freely positionable emission source and a detector, the possibility of expanding the overlap area of the radiation thus detected up to the structural limits of the medical imaging system is provided. A volume image data record, e.g. a computer tomography (CT), thus forms the complete investigation object located between the emission source and the detector.
