magnetic resonance imaging (MRI). Currently the use of ultra-high field (UHF) MRI at 7 tesla …

Employing electromagnetic fields (EMFs) in new wireless communication and sensing
technologies has substantially increased the level of human exposure to EMF waves. This …

The understanding of the human brain is one of the main scientific challenges of the twenty-
first century. In the early 2000s, the French Atomic Energy Commission launched a program …

Purpose A calibration‐free parallel transmission method is investigated to mitigate the
radiofrequency (RF) field inhomogeneity problem in brain imaging at 7 Tesla (T). Theory and …

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 …
