Design of multidimensional radiofrequency pulses in magnetic resonance imaging
… and simultaneous spatial-spectral selective excitation. While an elegant method known as Shinnar-Le Roux (SLR) method has been developed in one-dimensional RF pulse design, multidimensional RF pulse design remains an open question. The primary challenges are: a) the nonlinearity of the …

Coil performance evaluation based on electrodynamics : tools for hardware design and validation in magnetic resonance imaging
Parallel MRI techniques allow acceleration of MR imaging beyond traditional speed limits. In parallel MRI, radiofrequency (RF) detector coil arrays are used to perform some degree of spatial encoding which complements traditional encoding using magnetic field gradients. As the acceleration factor …

Parallel transmission for magnetic resonance imaging on a 9.4 Tesla Human System.
… very long and are impractical at high field. Parallel transmission, an emerging technique, makes it possible to design sufficiently short selective RF pulses for use in actual experiments. In this thesis, we demonstrate the first successful implementation of parallel transmission at an …
