Local SAR prediction in pTX MRI based on real-time multi-channel driving voltage measurements with directional couplers are prone to model variations even when the worst case values for different models a similar. Hence, when aiming to go beyond, i.e. below, the worst case scenario for patient safety in pTx MRI, even the careful validation of simulation results including the variability real life applications is already a challenging task.
