Abstract

In a magnetic resonance transmission method and magnetic resonance transmission operating therewith a high-frequency power amplifier emits an output signal with an actual amplitude and an actual phase to a magnetic resonance transmission antenna. A fraction of the signal is digitilized in a magnetic resonance receiver and is supplied to a pulse controller that is realized in software. An analog magnetic resonance reception signal of an object can be supplied to the magnetic resonance receiver during the pulses. The pulse controller determines correction values for a generator amplitude and a generator phase with which a pulse generator is driven, the pulse generator being connected upstream relative to the high-frequency amplifier.
