Synopsis
This work presents a method for local SAR and B1+ prediction using only a 9 seconds long localizer as input. The total procedure can be executed in less than 30 seconds for a birdcage setup and less than 45 seconds for an eight-channel PTx configuration, enabling seamless integration into the MR workflow.
