Specific absorption rate (SAR) simulations for low-field ( & lt;  0.1 T) MRI systems

ConclusionThis work presents a comprehensive overview of the transmit and SAR efficiencies for RF coils used for POC MRI neuroimaging. While SAR is not a problem for conventional sequences, the values derived here should be useful for RF intensive sequences such asT1 ρ, and also demonstrate that if very short RF pulses are required then SAR calculations should be performed.
