摘要： System and methods are provided for determining temperature with the aid of an intervention apparatus. A reference temperature at a detection location inside the examination object is detected using a reference temperature measuring unit. A relative temperature distribution in a measuring volume, having a spatial position in relation to the detection location of the reference temperature that is known, is detected using a temperature distribution measuring unit. An evaluation unit ascertains an absolute temperature distribution using the reference temperature and the relative temperature distribution.

摘要： A method determines an optimal structure of a high-frequency shield of a high-frequency antenna of a magnetic resonance arrangement. The high-frequency shield shields the high-frequency antenna from a gradient-coil arrangement. A three-dimensional initial structure of the high-frequency shield is defined in accordance with structural parameters and jointly with the high-frequency antenna, the gradient-coil arrangement, or both the high-frequency antenna and the gradient-coil arrangement. The structural parameters are optimized via an optimization method with respect to at least one optimization criterion.

摘要： A transmit coil arrangement for a magnetic resonance device includes a plurality of individually actuatable conductor loops following one after another in a peripheral direction and a longitudinal direction on a cylinder surface. At least two groups, at a distance from one another in the peripheral direction, of at least two conductor loops following one after the other in the longitudinal direction are provided in the peripheral direction. To decouple the at least two groups, each of the at least two groups is bounded at least in the peripheral direction by at least one screen surface extending essentially in a radial direction and the longitudinal direction.

摘要： A magnetic resonance facility having a cylindrical patient receiving unit includes a high-frequency shield. The high-frequency shield is disposed to enclose the patient receiving unit and shield at least one high-frequency coil from a gradient coil arrangement. The high-frequency shield is extendable to form a shielded chamber that shields the high-frequency coil from high-frequency signals outside the shielded chamber.

摘要： An antenna system for a magnetic resonance imaging system includes a plurality of antenna elements. The antenna elements are arranged in, at, or on support elements. The support elements are constructed so as to be non-expandable and have a constant surface dimension. Adjacent support elements are connected to an expandable connecting element. The dimensions of the connecting element may be changed by the expansion.

摘要： In an antenna selector switch and a switching method, a number of antenna units of a magnetic resonance apparatus can be operated via one RF channel. The antenna selector switch has at least two antenna connectors for connection with one antenna unit. A first of the antenna units can be set in terms of its resonance frequency via a control signal. The selector switch also has an RF channel connector for making a connection with a radio frequency unit of the magnetic resonance apparatus; and a switching unit to make a radio frequency connection between one of the antenna connectors and the RF channel connector. The switching unit can activated with the control signal. This allows a reduction of the necessary reception channels without additional control signal lines.
