摘要： A method for operating a magnetic resonance facility is proposed. The magnetic resonance facility has a number of power-consuming components. The power consumption is determined for each component. Operation of the components is controlled based on at least one criterion so that a predetermined threshold value for the overall power consumption of the magnetic resonance facility is not exceeded.

摘要： A magnetic resonance facility having a cylindrical patient receiving unit includes a high-frequency shield. The high-frequency shield is disposed to enclose the patient receiving unit and shield at least one high-frequency coil from a gradient coil arrangement. The high-frequency shield is extendable to form a shielded chamber that shields the high-frequency coil from high-frequency signals outside the shielded chamber.

摘要： A transmitter for pilot tone navigation in a magnetic resonance tomography system includes a power supply and an antenna. The transmitter is configured to transmit a pilot tone signal via the antenna. The transmitter also includes a decoupling element in order to protect a transmitter output from signals that the antenna receives with excitation pulses of the magnetic resonance tomography system during a magnetic resonance tomography. In a method, movement-dependent changes to the pilot tone signal of the transmitter are identified by a controller of the magnetic resonance tomography system.

摘要： A method for emitting a sequence of high frequency pulses that may have different envelopes in a magnetic resonance tomography system is provided. A digital instruction signal that specifies the envelope for the high frequency pulses that are to be emitted is received. A digital control signal is transmitted to a high frequency unit for generating high frequency pulses, depending on the instruction signal. A test signal that allows notification of a current overload situation is received. The current control signal is reduced if the test signal indicates an overload situation.

摘要： A local coil for a magnetic resonance imaging system for acquisition of magnetic resonance signals includes a receiving mechanism for wireless transmission of operating energy of the local coil and/or a signal of the magnetic resonance imaging system. The receiving mechanism is configured to take the operating energy and/or the signal from a supply field. A magnetic resonance imaging system is also provided. The magnetic resonance imaging system includes a transmitting mechanism for wireless transmission of operating energy of a local coil and/or a signal of the magnetic resonance imaging system. The transmitting mechanism has a transmission signal generator that is connected to a field source and a field sink. The transmitting mechanism is constructed such that, in operation, the operating energy and/or the signal is transmitted by a supply field that is present as an electrical alternating voltage field between the field source and the field sink.

摘要： A whole-body coil for a magnetic resonance tomography device includes one or more compensation capacitors between a high-frequency antenna and an RF shield. The one or more compensation capacitors each have variable capacitance caused by a variation in a distance of the RF shield to the high-frequency antenna.

摘要： A magnetic resonance tomography apparatus includes a receiving device having a number of magnetic resonance receive antennas for receiving a magnetic resonance signal in response to a radio frequency signal transmitted at a magnetic resonance frequency. A respective magnetic resonance receive antenna is connected to a parametric mixer. A receive circuit formed hereby is provided inside the cryostat and is coupled via a contactless communication interface to an evaluation circuit provided outside the cryostat. The evaluation circuit includes a local oscillator device for generating an auxiliary signal at an auxiliary frequency. The auxiliary signal is transmitted via the contactless communication interface to the receive circuit. The receive circuit is configured such that a mixed signal having a mixed frequency is generated via the parametric mixer from the auxiliary signal and the magnetic resonance signal and transmitted via the contactless communication interface to the evaluation circuit.
