(author), van den Berg, Cornelis A.T. (author), Raaijmakers, Alexander J. E. (author)Purpose: Patients who have medical metallic implants, e.g. orthopaedic implants and pacemakers, often cannot undergo an MRI exam. One of the largest risks is tissue heating due to the radio frequency (RF) fields. The RF safety assessment of implants is computationally demanding. This is due to the large dimensions of the transmit coil...journal article 2019

Fuchs, P.S. (author), Mandija, Stefano (author), Stijnman, Peter R.S. (author), Brink, Wyger M. (author), van den Berg, Cornelis A.T. (author), Remis, R.F. (author)In this paper, we present an efficient dedicated electrical properties tomography (EPT) algorithm (called first-order current density EPT ) that exploits the particular radio frequency field structure, which is present in the midplane of a birdcage coil, to reconstruct conductivity and permittivity maps in this plane from B ^ + 1 data. The...journal article 2018
