We built a phantom which exhibits significant localized
heating and provides good conditions for measuring
temperature rise with MR thermometry and/or using fiber
optic temperature probes. Measurements with this phantom
allow for local SAR validation for RF coil models, a
necessary step prior to relying on SAR simulations for
in-vivo safety decisions.
