Patent ID: 8729897

Claim:
A method to acquire spin echo-based magnetic resonance (MR) signals from an examination subject situated in an MR data acquisition unit, which comprises a radio-frequency (RF) module having a plurality of RF transmission channels that also respectively form a plurality of RF reception channels, said method comprising: operating the MR data acquisition unit to detect a two-dimensional spatial phase distribution in the examination subject by acquiring navigator signals via said plurality of RF reception channels; in a processor, calculating a phase and amplitude distribution, dependent on the spatial phase distribution of said navigator signals, for the plurality of RF transmission channels, that gives on refocusing pulse, among multiple RF refocusing pulses radiated in a multi-spin echo sequence following a single RF excitation pulse, a magnetic field that causes all spin-echo based MR signals detected in said multi-spin echo sequence to be detected along a same predetermined coordinate axis; and operating said MR data acquisition unit according to said multi-spin echo sequence by radiating said one RF refocusing pulse via said plurality of RF transmission channels with the calculated phase and amplitude distribution of the plurality of RF transmission channels, and detecting said spin echo-based MR signals via said plurality of RF reception channels, and making the detected spin echo-based MR signals available in electronic form at an output of said RF module.
