Parallel-Excitation Techniques for Ultra-High-Field MRI
2007Theoretical work on parallel RF transmission and recent experimental implementations on prototype systems indicate that parallel excitation has the potential to overcome critical obstacles to robust and routine human scanning at high field strength. As these developments are extended to 16- and 32-channel neuroimaging arrays, it seems likely that very ...

A Perspective into Ultra High Field MRI RF Coils
2007The advancement of MRI as a radiological instrument has been associated with a constant drive toward higher magnetic field strengths, resulting in higher operational frequencies. More powerful magnets bring the promise of enhanced signal to noise ratio resulting in exquisite resolution, and reduced scan times.

Methods for neuroimaging with ultra high field MRI
2019This work is focused on developing methods for neuroimaging in vivo at 7.0 T with high resolution and high contrast in a reasonable scanning time. The methods optimised here have been tested in various brain regions, in small cohorts, in both health and disease, including a consideration of the usefulness and pitfalls of high field MRI.
