  • Patent number: 9513351
    Abstract: 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.

  • Patent number: 9274190
    Abstract: 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.

  • Patent number: 7639011
    Abstract: A field distribution correction element for positioning on an examination subject in a magnetic resonance system for local influencing of the radio-frequency field distribution during a magnetic resonance acquisition has a system of electrically conductive dipole strips essentially running in parallel, arranged on a carrier element. In a corresponding method for generation of magnetic resonance exposures of an examination subject in a magnetic resonance system, for local influencing of the radio-frequency field distribution, such a field distribution correction element is positioned on the patient.

  • Patent number: 7550973
    Abstract: In a method and arrangement for local manipulation of a B1 field in a first region of an examination subject in an examination volume of a magnetic resonance system, a B1 measurement value that represents the B1 field in the sub-volume during an adjustment measurement is integrally determined, and in desired radio-frequency signal parameters for a subsequent magnetic resonance measurement are predetermined on the basis of the determined B1 measurement value. At least during the adjustment measurement, the B1 field is influenced within a second region counter to the manipulation intended in the first region by means of an auxiliary coil element which is arranged in or at the second region of the sub-volume remote from the first region.
