  • Transmitter/receiver antenna for MR with improved decoupling between antenna elements
    Patent number: 7916920
    Abstract: A magnetic resonance tomograph is provided with a magnetic resonance system comprising at least two high-frequency transmitting/receiving units, each containing 1) a high-frequency transmitting/receiving coil, 2) a high-frequency current source that can be coupled to the high-frequency transmitting/receiving coil for transmitting, and 3) an amplifier that can be coupled to the high-frequency transmitting/receiving coil for receiving. A selector switch is provided, which keys a supply voltage to disconnect the amplifier during a transmission operation and the high-frequency current source during a receiving operation from the high-frequency transmitting/receiving coil. An inductor and a capacitor are provided between the high-frequency transmitting/receiving coil and the amplifier and form a series resonating circuit at the magnetic resonance frequency.
