Method for performing multi-echo measuring sequence with enhanced spatial resolution, involves implementing preliminary phase-gradient pulse and two readout-gradient pulses with respective readout-gradient pulse-parameters

摘要

The method involves determining a ratio between the predetermined time difference (515) and a ratio of the predetermined maximum gradient pulse-amplitude (653) and the predetermined maximum gradient pulse-change rate (651). A preliminary phase-gradient pulse (403-1) is implemented, and the two readout-gradient pulses (403-2,404-2) are implemented with the respective readout-gradient pulse-parameters. An independent claim is included for a magnetic resonance system for performing a multi-echo measuring sequence with enhanced spatial resolution.
