The main risks associated with magnetic resonance imaging (MRI) have been extensively
reported and studied; for example, everyday objects may turn into projectiles, energy …

At ultra-high fields, the assessment of radiofrequency (RF) safety presents several new
challenges compared to low-field systems. Multi-channel RF transmit coils in combination …

Objective To define thresholds of safe local temperature increases for MR equipment that
exposes patients to radiofrequency fields of high intensities for long duration. These MR …

Over the past decades, significant improvements have been made in the field of
computational human phantoms (CHPs) and their applications in biomedical engineering …

There is a growing concern in the population about the effects that environmental exposure
to any source of “uncontrolled” radiation may have on public health. Anxiety arises from the …

Purpose This article investigates the safety of radiofrequency induced local thermal hotspots
within a 1.5 T body coil by assessing the transient local peak temperatures as a function of …

Purpose Radiofrequency energy deposition in magnetic resonance imaging must be limited
to prevent excessive heating of the patient. Correlations of radiofrequency absorption with …

Purpose MRI is increasingly used to scan pregnant patients. We investigated the effect of 3
Tesla (T) two‐port radiofrequency (RF) shimming in anatomical pregnant women models …

First in vivo brain conductivity reconstructions using Helmholtz MR-Electrical Properties
Tomography (MR-EPT) have been published. However, a large variation in the …

Purpose To assess the effect of radiofrequency (RF) shimming of a 3 Tesla (T) two‐port body
coil on B1+ uniformity, the local specific absorption rate (SAR), and the local temperature …
