Abstract:
1. A magnetic resonance scanner with a magnetic resonance system comprising at least two radio frequency transmitter/receiver units which each comprise: (a) a radio frequency transmitter/receiver coil, (b) a radio frequency current source coupled to the radio frequency transmitter/receiver coil for the transmission, (c) an amplifier coupled to the radio frequency transmitter/receiver coil for the reception, (d) a changeover switch designed to key a supply voltage to separate the amplifier in a transmission process and the radio frequency current source in a reception process from the radio frequency transmitter/receiver coil, (e) an inductor and a capacitor provided between the radio frequency transmitter/receiver coil and the amplifier and forming a series-resonant circuit at the magnetic resonance frequency, (f) a first diode arranged between the changeover switch ( (g) a second diode arranged between the radio frequency current source and the radio frequency transmitter/receiver coil, wherein, by means of the changeover switch, the magnetic resonance system
