Continuously digitally adjustable phase actuator

A magnetic resonance tomograph comprising:

• a phase actuator for a continuously adjustable phase displacement at a first frequency, the phase actuator comprising:
• a signal input;
• a signal output;
• a reference mass;
• a first inductance with a tapping point;
• a first continuously variable capacitance;
• and
• a transformation network,
• wherein the signal input and the signal output are electrically connected by the first inductance,
• wherein the first continuously adjustable capacitor is connected in parallel to the first inductance,
• wherein the tapping point is connected via a transformation network to the reference mass, and
• wherein an impedance value of the transformation network corresponds to a quarter wave transform of a capacitance value of the first continuously variable capacitance at the first frequency.
