Real-time Local SAR simulation is critical to the
success of multi-channel RF transmission at high fields.
The speed of conventional electromagnetic simulation
methods is insufficient even on parallel computation
platforms. We propose a novel domain-decomposition
method that applies different numerical algorithms in
the interior and the exterior of a human body model.
These different methods then interface on the surface of
the human body model. Preliminary studies show that on a
single-core CPU, simulating an eight-channel brain
imaging array only in 30 seconds.
