Generic SAR behavior in MRI of the head was studied to evaluate whether patient-specific SAR models which are consuming to construct may be replaced by a generic SAR model. Patient-specific SAR constrained B1+ shimming was performed with generic SAR models. This approach was found to be well suitable for patient-specific B1+ shimming compliant with SAR safety norms at a minimal expense of increased B1+ heterogeneity.
