Patent number: 9513351Abstract: 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.Type: GrantFiled: September 14, 2012Date of Patent: December 6, 2016Assignee: Siemens AktiengesellschaftInventors: Stephan Biber, Daniel Driemel, Helmut Greim, Steffen Wolf

Patent number: 9274190Abstract: 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.Type: GrantFiled: November 13, 2012Date of Patent: March 1, 2016Assignee: Siemens AktiengesellschaftInventors: Daniel Driemel, Helmut Greim, Steffen Wolf

Patent number: 7550973Abstract: 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.Type: GrantFiled: March 21, 2008Date of Patent: June 23, 2009Assignee: Siemens AktiengesellschaftInventors: Helmut Greim, Steffen Wolf
