1. A radio frequency (RF) pulse alignment method for determining transmit scaling factors used in control of a magnetic resonance system having a plurality 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 plurality of RF transmit channels in the course of a control function, the method comprising: acquiring a plurality of test images of an object that is to be examined using different candidate sets of transmit scaling factors for the plurality of RF transmit channels; determining, after acquiring the plurality of test images, optimal transmit scaling factors with respect to a predefined criterion for each RF transmit channel of the plurality of RF transmit channels based on the plurality of acquired test images; and performing a measurement, the performing comprising transmitting an RF pulse, via the plurality of RF transmit channels, using the determined optimal transmit scaling factors.
