摘要： A circuit arrangement for driving a transmission coil arrangement with at least two individual transmission coils of a magnetic resonance system for supplying a radiofrequency signal for producing alternating electromagnetic fields over at least two channels, with in each case a digital section and an analog section, is provided. In the digital section, in an envelope generator, base frequency signals that respectively generate an envelope are provided. The circuit arrangement also includes an intermediate frequency oscillator that generates a common intermediate frequency, a frequency mixer per channel for mixing the common intermediate frequency into the base frequency signals, and in the analog sections of the channels, respectively, second frequency mixers that mix a common radiofrequency signal into each base frequency signal. The envelope is transmitted, with the mixed-in intermediate frequency signal, and the total signal thus obtained is respectively conducted to an individual transmission coil via a respective amplifier.

摘要： The invention relates to a correction method for correction of noise resulting from gradient artifacts in ECG signal data records recorded in a magnetic resonance device by an ECG measuring apparatus. A first correction data record is determined with a reference point of the ECG measuring apparatus located at a first position in the magnetic resonance device. An ECG signal data record is measured with the reference point of the ECG measuring apparatus located at a second position in the magnetic resonance device. A modified correction data record is specified as a function of the first correction data record and the first and second position of the reference point. The ECG signal data record is corrected based on the modified correction data record.

摘要： A modulator for radio-frequency signals designed an entirely digital modulator has two mixer stages connected in series. The first mixer stage implements with a relatively low first sample rate a frequency mixing with a first oscillator frequency that is adjustable with high precision. The second mixer stage implements a frequency mixing with a significantly higher second sample rate and with a relatively coarsely adjustable second oscillator frequency. The downstream second mixer stage, in the case of a single mixer stage, the mixer stage, has at least two phase accumulators that are incremented with the higher second sample rate but with different incremental values. The output signal of at maximum one of the phase accumulators is evaluated at any point in time.
