Development and optimization of high resolution multi-shot magnetic resonance acquisitions for diffusion weighted imaging
… challenges being low signal to noise ratio and motion induced phase errors. The work in this thesis aims at creating an acquisition that is able to image with a high SNR efficiency in order to achieve higher resolutions. This is accomplished through the use 3D excitations in order to optimize …

Application of diffusion weighted imaging in studying motor control and moving towards higher resolution diffusion imaging
… the challenges associated with long readouts, motion induced phase errors, and image reconstruction were developed and tested. Results are given for 1 mm isotropic resolution on volunteer's brains scanned on a 3 T MRI scanner.

High resolution 3D diffusion tensor imaging for delineating neuronal architectures
… (b) sensitivity to numerous artifacts such as motion-induced phase error and/or magnetic susceptibility, (c) requirement of maintaining a reasonable scan time (< 30 minutes). The analysis in this dissertation shows that 3D encoding is required for high isotropic resolution because of its …
