ABSTRACT:
An arrangement configured for controlling an antenna arrangement in a magnetic resonance device has an antenna arrangement that surrounds an examination region and that has at least one antenna element configured for emitting an amplified transmit signal. At least one amplifier is provided, at the input of which a high-frequency transmit signal is connected, which is present on the output side of the amplifier as an amplified transmit signal. The amplifier is connected to a feed point of the antenna arrangement on the output side, in order to emit the amplified transmit signal. Coil windings of a primary gradient coil are also provided, which at least partially include the antenna arrangement and the examination region. Coil windings of a secondary gradient coil at least partially include the coil windings of the primary gradient coil, the antenna arrangement (and the examination region). The coil windings of the secondary gradient coil and the coil windings of the primary gradient coil are at a distance from one another, and within that distance the at least one amplifier is arranged.
