Abstract:
1. An arrangement for controlling N individual antennas of an antenna arrangement in a magnetic resonance apparatus, said arrangement comprising: a signal division device comprising a plurality of inputs and N outputs, each input having a transmission signal thereat and said signal division device dividing each transmission signal among all of said N outputs; said signal division device comprising a plurality of transmission branches, each of said transmission branches comprising a plurality of components that form a modulated transmission signal that is modulated specifically to that transmission branch and that is amplified, thereby making the transmission signal specific to that transmission branch; the respective outputs of said signal division device being connected to respective individual antennas of the antenna arrangement; said transmission branches being respectively connected with respective inputs of said signal division device to supply the transmission signal from that transmission branch to the input of the signal division device connected thereto; and said plurality of inputs of said signal division device and said plurality of transmission branches each being equal to N, and each of said transmission branches comprising a modulator that modulates said transmission signal specific to that transmission branch, a transmission power amplifier that amplifies the modulated transmission signal, and a transmission reception unit that connects that transmission branch with one of the inputs of the device for signal division.
