摘要： A simple connection of a coil with a magnetic resonance tomography (MRT) is facilitated by a method and an adapter wherein a coil-connection element of at least one local coil is connected with an MRT-connection element of an MRT system. The adapter has a coil-connection element adapter designed to form a connection with at least one coil-connection element of at least one local coil. The adapter also has at least one MRT-connection element adapter designed to form a connection with an MRT-connection element of an MRT system. The adapter can be fixed mechanically to a fixing element of the MRT system.

摘要： A magnetic resonance coil for transmitting and/or receiving magnetic resonance signals is provided. The magnetic resonance coil includes at least two overlapping coil elements. Coil conductors of the at least two overlapping coil elements intersect in intersection regions and are arranged on a support. Mutually overlapping coil elements of the at least two overlapping coil elements are arranged on different sides of the support. The support is formed from at least three layers of a support material. A cavity that is filled with air or a filler material, the dielectric constant of the filler material being lower than the dielectric constant of the support material, is provided in the intersection regions in a middle layer of the at least three layers.

摘要： A local coil for a magnetic resonance tomography device includes a plurality of antenna elements. Each antenna element of the plurality of antenna elements has two conductor tracks. The conductor tracks are disposed on opposite sides of an insulator and are connected electrically conductively to one another by plated through-holes through the insulator. In areas, in which conductor tracks of at least two antenna elements of the plurality of antenna elements cross, at least one antenna element of the at least two antenna elements only has a conductor track on one side of the insulator.

摘要： An array antenna for magnetic resonance applications has at least one first and one second conductor loop in which radio-frequency currents oscillate in respective current flow directions in the operation of the array antenna. The respective conductor loops are divided into first or second loop segments in their respective current flow directions. The first loop segments are capacitively coupled with one another by first capacitors, the second loop segments are capacitively coupled with one another of second capacitors. The loop segments are fashioned as conductor traces of a circuit board that has at least one first and one second electrically insulating support layer. The support layers abut one another with the exception of conductor traces arranged between the first support layer and the second support layer. The capacitors are respectively formed by end regions of the first or second loop segments abutting one another as viewed in the respective current flow direction. The end regions overlap as viewed in the respective current flow direction. Exactly one of the support layers is between the overlapping end regions of the loop segments. The first and the second conductor loops intersect in intersection regions. Neither the a loop segments of the first conductor loop nor a loop segments of the second conductor loop are arranged between the first support layer and the second support layer in the intersection regions.
