摘要： A detection unit is disclosed for arrangement in the main magnet of an MR device, which has both an RF transceiver system and a PET detector. In at least one embodiment the RF transceiver system is divided into two parts and the two parts are arranged upstream and downstream of the PET detector in the longitudinal direction of the patient tunnel. The RF transceiver system and PET detector are applied to the same image volume. In at least one other embodiment, an MR device is equipped with the detection unit, and in at least one other embodiment, a method operates the detection unit.

摘要： The disclosure relates to a method for determining a transfer function of a transmitting system of a magnetic resonance device, to a method for the correction of a transmission signal of a magnetic resonance device, to a corresponding magnetic resonance device, and to a computer program product for carrying out the method. The method includes determining a transfer function using a transmission characteristic of a transmitting system of the magnetic resonance device, wherein the transfer function is frequency-dependent. A transmission signal may be corrected using the transfer function. An excitation pulse may be emitted by the transmitting system using the corrected transmission signal.

摘要： The embodiments relate to a magnetic resonance coil for a magnetic resonance device with a measuring chamber for an examination object and a cylindrical birdcage antenna arrangement having a plurality of antenna elements disposed at least in some areas around a measuring chamber in the form of circumferential antenna rings or axial outer rods connecting the rings. The antenna elements include electric components, e.g., reactive capacitive and/or inductive systems. The magnetic resonance coil also has at least two antenna feeds, e.g., phase-offset in relation to one another by 90°, by which radio-frequency energy is able to be supplied to the birdcage antenna arrangement. The antenna feeds include at least one symmetrical feed via at least one of the electric components of the birdcage antenna arrangement as well is at least one assigned asymmetrical feed between the birdcage antenna arrangement and a screen connection.

摘要： A method determines an optimal structure of a high-frequency shield of a high-frequency antenna of a magnetic resonance arrangement. The high-frequency shield shields the high-frequency antenna from a gradient-coil arrangement. A three-dimensional initial structure of the high-frequency shield is defined in accordance with structural parameters and jointly with the high-frequency antenna, the gradient-coil arrangement, or both the high-frequency antenna and the gradient-coil arrangement. The structural parameters are optimized via an optimization method with respect to at least one optimization criterion.
