In vivo radiofrequency (RF) heating was simulated by
solving the first principles based generic bioheat
transfer model (GBHTM) in a digital pig due the power
deposition from a 3T body coil. The simulations were
validated by measuring the heating using fluoroptic
probes in anesthetized swine due to the whole-body
average power deposition of 2.77 W/kg for an hour in a
3T scanner. The GBHTM predicted the RF heating
accurately. The simulations and measurements provided
fundamental understanding of the RF energy transport and
related heating in vivo to make MRI more powerful as
well as improve patient safety.
