Publikováno v: Magnetic Resonance in Medicine. 78:2449-2459

Purpose We introduce a new MR-based method to determine the transfer function (TF) for radiofrequency (RF) safety assessment of active implantable medical devices. Transfer functions are implant-specific measures that relate the incident tangential e

Publikováno v: Health Physics, 107(5), 369-381. Lippincott Williams & Wilkins

This study analyzes the exposure of pregnant women and their fetuses in three different gestational stages to electromagnetic radiation in the radio frequency range in the near- and the far-field using numerical modeling. For far-field exposure, the

Analysis of human brain exposure to low-frequency magnetic fields: A numerical assessment of spatially averaged electric fields and exposure limits

Autor: J F Bakker, Gerard C. van Rhoon, Valerio De Santis, Nicholas Chavannes, Juan R. Mosig, X. L. Chen, S. Benkler, Niels Kuster

Publikováno v: Bioelectromagnetics, 34(5), 375-384. Wiley-Liss Inc.

Compliance with the established exposure limits for the electric field (E-field) induced in the human brain due to low-frequency magnetic field (B-field) induction is demonstrated by numerical dosimetry. The objective of this study is to investigate
