ABSTRACT:
An arrangement for controlling individual antennas of an antenna arrangement in a magnetic resonance apparatus has a device for signal division. This device is designed such that each transmission signal present at an input of the device for signal division is divided among all outputs of the device for signal division. Each output of the device for signal division is connected with a respective individual antenna. A number of transmission branches are provided for the inputs of the device for signal division. Each transmission branch has components that form a transmission signal that is modulated specific to the transmission branch and is amplified. Each transmission branch is connected with a respective associated input of the device for signal division, such that the transmission signal therefrom arrives at the associated input.
