Claim:
1. A method to optimize a magnetic resonance sequence for operating a magnetic resonance apparatus, comprising: providing a computerized processor with a magnetic resonance sequence that includes first imaging parameters, said magnetic resonance sequence with said first imaging parameters, when executed by a magnetic resonance apparatus to acquire magnetic resonance data from a subject, from which magnetic resonance images are reconstructed, producing acoustic noise at a first acoustic noise volume level and magnetic resonance images with image noise at a first signal-to-image noise ratio; in said computerized processor, executing an optimization algorithm that automatically optimizes at least said first imaging parameters in said magnetic resonance sequence to produce an optimized magnetic resonance sequence that, when executed by said magnetic resonance apparatus, produces acoustic noise at a second acoustic noise volume level that is reduced by at least 3 dB relative to said first acoustic noise volume level, and magnetic resonance images with image noise at a second signal-to-image noise ratio that is reduced by a maximum of 35% relative to said first signal-to-image noise ratio; and making the optimized magnetic resonance sequence available in electronic form at an output of said processor in a format for execution of said optimized magnetic resonance sequence by said magnetic resonance apparatus.
