1. A radio frequency (RF) pulse alignment method for determining transmit scaling factors used in control of a magnetic resonance system having a number of RF transmit channels, via which RF pulse trains are transmitted in parallel during operation, wherein a common reference pulse train is specified for the RF transmit channels in the course of a control function, the method comprising: acquiring a plurality of candidate images of an object that is to be examined using different candidate sets of transmit scaling factors; and determining optimal transmit scaling factors with respect to a predefined criterion for each of the RF transmit channels based on the plurality of acquired candidate images.
