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： An apparatus checks for a presence of an electrically conductive body in the near field of charging coils of an arrangement for induced charging. At least one transmitting device provides a transmission signal in the form of a magnetic field. At least one receiving device generates a reception signal from the transmission signal and induced into the receiving device. The transmitting device and the receiving device are formed in such a way that, when the electrically conductive body is present, a first reception signal forms and, when the electrically conductive body is absent, a second reception signal, different than the first, forms in the receiving device on account of the induced transmission signal. The transmitting device and the receiving device are formed in a manner dependent on the magnetic field of the charging coils in such a way that, when the electrically conductive body is absent, partial reception signals form in the receiving device on account of the induced transmission signal, where partial reception signals substantially cancel one another out in the reception signal.

摘要： A two-channel magnetic resonance tomography system is provided with a regulation circuit for an amplification system in order to be able to take into account different load situations of the MRI system in a flexible and efficient manner. It is thus possible to improve the MRI measurements greatly if the MRI system is set to the respective load situation beforehand by an idle state measurement. The adaptation may optionally also be carried out during the MRI measurement. Therefore, a multiplicity of completely different load situations may be taken into account in an optimized manner by the regulation circuit.

摘要： A system for electromagnetic excitation of an object under examination during magnetic resonance tomography includes a radio frequency (RF) device for generating a radio-frequency signal and a plurality of antennas for emitting the radio-frequency signal. A signal connection exists between the output of the RF device and the plurality of antennas. A source impedance of the signal connection to the output of the RF device at a connection point of the plurality of antennas is significantly higher than the impedance of the plurality of antennas at the connection points, so that the plurality of antennas are fed in a current source feed mode if a radio-frequency signal is present.

摘要： The present embodiments relate to a balanced-to-unbalanced transformer for converting a symmetrical high-frequency signal into an asymmetrical high-frequency signal. The balanced-to-unbalanced transformer includes two coil windings made of wire. The two coil windings are electrically insulated from each other and are wound on a winding form. Each of the two coil windings has an input at one end of the winding form for the symmetrical high-frequency signal and an output at another end of the winding form for the asymmetrical high-frequency signal. The two coil windings lie on top of one another in a radial direction of the winding form.
