    摘要： A magnetic resonance device includes a radiofrequency unit that includes a radiofrequency antenna, at least one radiofrequency line and at least one radiofrequency injection point. Radiofrequency signals are transferred to the radiofrequency antenna by the at least one radiofrequency line and are coupled into the radiofrequency antenna at the at least one radiofrequency injection point. The magnetic resonance device also includes a patient receiving zone that is at least partially enclosed by the radiofrequency antenna, and a motion detection unit for detecting a movement of a patient that may be positioned within the patient receiving zone. At least one radiofrequency line includes at least one injection element by which at least one motion detection signal of the motion detection unit is coupled into the radiofrequency line.

    摘要： An MR device includes at least one body coil for generating a B1 magnetic field and at least one radiofrequency line routed through the B1 magnetic field. The at least one radiofrequency line has at least one frequency filter for blocking a voltage induced by the B1 magnetic field. At least one section of the radiofrequency line routed through the B1 magnetic field is embodied in printed circuit board technology on at least one printed circuit board, and information-carrying signals may be transmitted over the at least one radiofrequency line on a different frequency than the frequency of the voltage induced by the B1 magnetic field.

    摘要： An arrangement for processing a non-symmetrical signal includes an apparatus configured to balance and filter an image frequency of a nominal frequency of the non-symmetrical receiving signal. The apparatus includes a modified Boucherot bridge having a series or parallel oscillating circuit that replaces inductive or capacitive components of a conventional Boucherot bridge, such that the modified Boucherot bridge is in the harmonized state with the image frequency to be faded out and has a predetermined impedance with the nominal frequency on its symmetrical output terminals. The nominal frequency has a predetermined impedance on its symmetrical output terminals. The nominal frequency is transmitted as a signal balanced to ground to the symmetrical output terminals of the modified Boucherot bridge.

    摘要： A receiver assembly of a magnetic resonance (MR) system for generating MR recordings of an examination object includes a plurality of reception channels for receiving and amplifying MR signals from reception coils of the MR system connected therewith. A calibration data memory for storing calibration data for the plurality of reception channels is arranged on the receiver assembly. The receiver assembly includes a data link for transmitting the calibration data to the MR system.
