    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 method and a magnetic resonance apparatus compensate for inhomogeneities in a magnetic field generated by the magnetic resonance apparatus with a shim coil of the magnetic resonance apparatus. The shim coil is arranged at an object under investigation. A position and an orientation of the shim coil are automatically determined. The inhomogeneities of the magnetic field are determined. The inhomogeneities are compensated for via the shim coil depending on the position and the orientation of the shim coil.

    摘要： In a contacting system and method for contacting magnetic resonance local coils with a unit for additional signal processing of a magnetic resonance data acquisition unit, a number of coil coupler elements are electrically connected with the magnetic resonance local coils and apparatus coupler elements are mounted at the magnetic resonance tomograph, and are electrically connected with a unit for signal processing. The coil coupler elements and the apparatus coupler elements are fashioned so that, given a movement of the local coils along a movement path in the magnetic resonance data acquisition unit, a successive contacting of at least a portion of the coil coupler elements with apparatus coupler elements ensues at least over a specific path segment of the movement.

    摘要： A local coil arrangement for magnetic resonance applications has a mechanically dimensionally stable bearing element. A patient bed for a magnetic resonance system has a support surface to support a patient. In operation, the supporting element rests on the patient bed. In this state, it transfers the weight of the local coil arrangement to the patient bed. The local coil arrangement has at least one local coil to excite and/or to receive magnetic resonance signals. Furthermore, it has a multipole, prefabricated electrical interface via which the local coil can be electrically contacted. The electrical interface is arranged so as to be dimensionally stable at the bearing element. Positioning aids for the positioning of the local coil arrangement are arranged on the support surface. In the region of the positioning aids, a multipole, prefabricated electrical counter-interface is arranged so as to be mechanically dimensionally stable. By a corresponding positioning of the supporting element on the support surface of the patient bed, the weight of the local coil arrangement is transferred to the patient bed and the electrical interface is mechanically and electrically plugged into the electrical counter-interface.
