Radiofrequency safety modelling of parallel transmit magnetic resonance imaging

Abstract:

Radio-frequency (RF) safety plays an important role in Magnetic Resonance Imaging (MRI) with the goal of assuring patient safety and preventing excessive RF heating. Historically, RF safety in MRI has been monitored using pre-calculated specific absorption rate (SAR) limits which indicate the amount of energy that can be delivered safely to the subject. Electromagnetic (EM) simulations have usually been performed to assess the electric field and RF energy levels that are experienced by the...
