Patent ID: 7960971

Claim:
A method for determining a flip angle distribution in a magnetic resonance (MR) data acquisition unit having a radio-frequency antenna arrangement that is configurable to form a plurality of different transmission configurations, including a reference transmission configuration, comprising the steps of: operating said MR data acquisition unit to obtain MR data from a volume in an examination subject located in an examination volume of said MR data acquisition unit, by executing an interleaved multi-slice acquisition procedure comprising an excitation pulse and a refocusing pulse; in said interleaved multi-slice acquisition procedure, emitting one of said excitation pulse and said reference pulse as a slice-selective pulse and emitting the other of said excitation pulse and said refocusing pulse as a weakly slice-selective pulse; during said interleaved multi-slice acquisition procedure, configuring said antenna arrangement to form said reference transmission configuration and configuring said antenna arrangement to form a different transmission configuration, other than said reference transmission configuration, respectively, while emitting said excitation pulse and said reference pulse, respectively; and in a computerized processor, determining said flip angle distribution from said MR data, and making said flip angle distribution electronically available in a form for further processing thereof.
