Radiation Dominated Electromagnetic Shield

Radiation Dominated Electromagnetic Shield
We analyze the radiating electron interaction with oscillating electric and magnetic field configurations, which represent three-dimensional standing electromagnetic waves having various electromagnetic field polarizations. During collision of a high energy beam of ultra-relativistic electrons with a high amplitude electromagnetic field, when the ...

Coaxial Dipole Array With Switching Transmit Sensitivities for Ultrahigh Field MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate dipole antennas with electronically switchable transmit field patterns to improve flip angle homogeneity in ultra‐high field MRI. Methods Reconfigurable dipole elements that could produce two distinct electronically switchable B1+$$ {B}_1^{+} $$ field profiles were conceptualized and constructed. Eight such elements were

Validating Numerical Simulations to Support Experimental Testing of MRI Gradient‐Induced Heating of Passive Implants

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Numerical simulations can be adopted to aid the evaluation of the interaction between switched gradient fields and metallic implants and estimate the possible temperature increase. Anyway, an analysis of the consistency of their prediction with experiments is lacking, differently from what can be found for exposure to radiofrequency ...

A Numerical Alternative to MR Thermometry for Safety Validation of Multi‐Channel RF Transmit Coils

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study proposes a numerical technique to estimate peak local specific absorption rate (SAR) uncertainty of multi‐channel RF coils during the process of safety validation as an alternative to experimental temperature and electric‐field measurements, and demonstrates its use to enable human studies at 10.5 T.

A Hybrid RF Coil for Whole‐Brain Imaging in Non‐Human Primates at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ultra‐high field MRI (≥ 7 T) offers unprecedented potential for mapping non‐human primate (NHP) brain function. However, complex electromagnetic systems are required to meet the challenges of UHF imaging and the mechanical demands of awake NHP studies.
