  • Patent number: 12181545
    Abstract: A coil assembly for use as a transmission and/or receiving coil in an MR system comprises a dipole antenna assembly with multiple dipole antennas. Connection elements are converted from an electrically conductive state to an electrically non-conductive state. In the electrically conductive state, the dipole antennas form a cylindrical volume coil and/or a conductor loop assembly, in particular a flat conductor loop assembly. The connection elements comprise blocking circuits which automatically block when a high-frequency alternating voltage with a frequency corresponding to the blocking frequency of the connection element blocking circuits is applied to the coil assembly.
