摘要： An arrangement to transmit magnetic resonance signals has a local coil composed of a number of individual antennas for acquisition of radio-frequency signals of a magnetic resonance examination. Preamplifiers amplify the radio-frequency signals, and a transmission device transmits the radio-frequency signals from the local coil to the preamplifiers. The transmission device is fashioned as a readout coil and has a number of individual antennas. The individual antennas of the readout coil are magnetically coupled with the individual antennas of the local coil, with the individual antennas of the local coil and the individual antennas of the readout coil forming a linear MIMO transmission system describable by a transmission matrix.

摘要： In a method for processing radio frequency signals of a magnetic resonance imaging system in which the coil portion of the magnetic resonance imaging system includes a body coil and a local coil, radio frequency signals are supplied to the body coil, and these radio frequency signals are coupled to said local coil, and transmitted by said local coil into a region to be examined. A corresponding radio frequency system has a local coil and a body coil, with power coupling between the local coil and the body coil; during the phase for transmitting the radio frequency signals. The body coil serves to couple the radio frequency signals to be transmitted to the local coil, and the local coil serves to transmit the coupled radio frequency signals to a region to be examined. This method and system allow the transmitting function of the local coil to be achieved without having a coil plug on a patient bed to provide a radio frequency signal transmitting channel.

摘要： 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.

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.
