Abstract

In order to provide an effective optimization of a magnetic resonance sequence, particularly with regard to optimizing the slew rates of gradient switching sequences of the magnetic resonance sequence, in a method for optimizing a magnetic resonance sequence of a magnetic resonance apparatus, wherein the magnetic resonance sequence includes multiple pre-set gradient switching sequences with multiple pre-set slew rates, the multiple pre-set slew rates are provided to a computer wherein the multiple pre-set slew rates are evaluated. At least one optimization measure for the magnetic resonance sequence is defined based on the evaluation of the multiple pre-set slew rates. The magnetic resonance sequence is optimized based on the at least one pre-set optimization measure, wherein the optimized magnetic resonance sequence has multiple optimized gradient switching sequences with multiple optimized slew rates, and the multiple optimized slew rates being optimized in relation to the multiple pre-set slew rates.
