Flow chart depicting the methodology for fast computation of patient-specific SAR and B1+ maps. The offline phase consists of adaptive mesh refinement and precomputation of the coil/shield impedance matrix at the Larmor frequency. The on-the-table phase consists of the MRI acquisition (3D DIXON), fast segmentation into air, bone, fat, and soft tissue using a computer-vision based segmenter, and EM simulation using MARIE.
