Applications of parallel radiofrequency transmission to ultra-high-field magnetic resonance imaging

Abstract:

Increasing the static magnetic field (B0) strength of magnetic resonance imaging (MRI) scanners improves the signal-to-noise ratio (SNR). Higher SNR may be used for more sensitive, faster, and higher resolution imaging.

Despite its potential, the biggest challenges for ultra-high field MRI is inhomogeneity in the radio-frequency field (B1+), which causes spatially varying flip angles when using fixed-frequency pulses, leading to undesirable perturbations in signal and contrast. The...
