In a method and apparatus for optimizing the signal-to-noise ratio (SNR) of a magnetic resonance (MR) dataset acquired by means of a magnetic resonance system having at least one transmit coil, a measurement protocol for an acquisition that is to be performed in order to obtain the MR dataset of a predefined measurement volume. A deviation of an actual flip angle from the predefined flip angle in a specific area of the predefined measurement volume is determined for a preset transmitter scaling. The transmitter scaling of the RF pulse is adjusted in order to correct the actual flip angle so that the actual flip angle is approximated to the predefined flip angle in the specific area. The MR dataset is acquired with the adjusted transmitter scaling.
