Abstract

An RF pulse alignment method for determining transmit scaling factors used in the control of a magnetic resonance system having a number of radiofrequency transmit channels, via which RF pulse trains are transmitted in parallel during operation, is provided. A common reference pulse train is specified for a number of the radiofrequency transmit channels in the course of the control function. A plurality of candidate images of an object that is to be examined are acquired using different candidate sets of transmit scaling factors. Optimal transmit scaling factors with respect to a predefined criterion are selected for each of the radiofrequency transmit channels based on the acquired candidate images.
