Power deposition in tissues of a person subject to MRI examination is a significant point of concern today. Numerical electromagnetic simulation offers a way to model this complex problem with a sufficient degree of accuracy. Assessment of power deposition due to presence of implantable leads has been widely applied using the transfer function method. It relays on the incident tangential electric field (Etan) along the lead trajectory. This paper investigates how the precision of a numerical human model influences calculated Etan.
