Circuit for an image producing magnetic resonance tomography device (101), the at least one transmitter or induction coil (108a, b, c) for transmitting a magnet - field (b1 (x, y, z, t)) comprises,characterized by the,that it is in the transmission path between an amplifier (111) and at least one transmitter or induction coil (108a, b, c,) of the magnetic resonance tomography device (101), can be arranged or arranged in a hybrid - coupler (hy2) and at least one phase shifter (phi1 and phi2) comprises,and that they are in the transmission path between an amplifier (111) and at least one transmitter or induction coil (108a, b, c) for transmitting a b1 - magnet - field (b1 (x, y, z, t)) two hybrid - coupler (hy1, hy2) and at least two phase shifter (phi1 and phi2) comprises.
