Patent ID: 8358131

Claim:
An antenna assembly for magnetic resonance tomography, comprising: an antenna configured to at least receive magnetic resonance signals; at least one impedance transformation circuit electrically connected to said antenna; said antenna also being configured to transmit radio-frequency signals for magnetic resonance tomography, and said antenna being connected to said impedance transformation circuit at a first side of said impedance transformation circuit; and said antenna assembly comprises a standing wave barrier connected to a second side of said impedance transformation circuit, a switch connected to said standing wave barrier at a side thereof opposite to said impedance transformation circuit, a feed line connected to a source of radio-frequency energy, and a reception device that receives said magnetic resonance signals, said switch being switchable between a first switch position that connects said antenna, via said impedance transformation circuit and said standing wave barrier, to said feed line, and a second position that connects said antenna, via said impedance transformation circuit and said standing wave barrier, to said reception device.
