Patent ID: 7123010

Claim:
A magnetic resonance apparatus comprising: a basic field magnet that generates a basic magnetic field in an examination volume; at least one gradient coil that generates at least one gradient magnetic field in the examination volume; a plurality of radio-frequency antennas disposed in and forming a single array, around the examination volume, configured for radiating RF energy into, and receiving RF energy from, the examination volume; a plurality of separate transmission channels respectively connected to the plurality of RF antennas; a plurality of separate reception channels respectively connected to the plurality of RF antenna; and a control unit connected to said at least one gradient coil and to said single array of RF antennas for operating said at least one gradient coil and said single array of RF antennas in order to excite and acquire magnetic resonance signals having an amplitude and a phase, from the subject, said control unit determining, for each antenna in said plurality of RF antennas forming the single array, the amplitude and the phase of the magnetic resonance signal received by the respective antenna, and said control unit also activating the same plurality of RF antennas of said single array independently of each other in order to emit RF energy of a prescribed phase and amplitude into the examination volume in order to generate an RF field focused in the examination volume configured for hyperthermic treatment of the subject.
