摘要： A conductor arrangement includes a conductor that extends along a conductor axis. The conductor arrangement also includes a standing wave trap to which the conductor is coupled in order to damp standing waves that are excited by an RF field from outside the conductor arrangement. The standing wave trap is in the form of a dielectric resonator device.

摘要： A magnetic resonance system has a patient receptacle and a base body. The patient receptacle has a subframe and a patient bed supported thereon so as to move a patient thereon through the base body. The base body has a basic field magnet system, a gradient system and an RF system that are operable to obtain an analog magnetic resonance signal from the patient. The patient receptacle has a signal conversion device composed of an A/D converter, a modulator, and a transmitter. The base body has a signal conversion device composed of a receiver and a demodulator. The A/D converter receives the magnetic resonance signal and digitizes it. The modulator modulates a carrier signal with the digitized magnetic resonance signal. The transmitter transmits the modulated carrier signal via an air gap to the receive. The receiver receives the transmitted carrier signal. The demodulator extracts the digitized magnetic resonance signal from the received carrier signal by demodulation and supplies it to an evaluation device for continuing evaluation.

摘要： A whole-body antenna for a magnetic resonance apparatus has an antenna structure composed of a number of antenna rods extending in a rod direction between first and second ends of the antenna structure. The antenna rods are distributed around a central axis of the antenna structure, forming an examination region for an examination subject in a magnetic resonance examination. The antenna rods are coupled to each other at their first ends by a ferrule. Each of the rods is a hollow rod, and each rod is connected at its second end to ground via a hollow ring. Conductors are routed in the interior of the hollow rods, and can be routed through the hollow ring to the exterior of the antenna structure.

摘要： A patient positioning couch includes an illumination apparatus having at least one light source that is arranged in the patient positioning couch. The patient positioning couch is capable of being placed in an examination area of a medical device. Through the arrangement of the at least one light source of the illumination apparatus of the patient positioning couch, it is always ensured that the illumination does not lose its location relative to a patient or another object positioned on the patient positioning couch, even if the position of the patient positioning couch changes, e.g. if the patient positioning couch is moved into or out of the examination area. At the same time an especially space-saving illumination of the examination area can thus be achieved.

摘要： A method and an arrangement for the production of composite work pieces of layers laminated to each other, with at least one layer representing a glass plate. First, at least one composite work piece is laminated in a lamination press under the effects of pressure and heat in order to at least activate the adhesive material used for lamination. Then the composite work piece is removed from the lamination press and transported into a curing station and/or cooling station for curing and/or cooling. A testing device for detecting broken glass in the composite work piece is arranged between the lamination press and the curing station or between the lamination press and the cooling station, which detects potentially present broken glass by testing the inherent stability of the composite work piece.
