Advanced parallel magnetic resonance imaging methods with applications to MR spectroscopic imaging
… a framework for acceleration of conventional MRI encoding using an array of receiver coils with spatially-varying sensitivities. Novel encoding and reconstruction techniques for parallel MRI are investigated in this dissertation. The main goal is to improve the actual reconstruction methods and to …

Functional Magnetic Resonance Imaging of Breast Cancer
… A multi-shot DWI technique, multiplexed sensitivity encoding (MUSE), can improve the image quality of DWI. A MUSE protocol has been optimised through a series of phantom experiments and validated in 20 patients. Comparing MUSE to conventional DWI, statistically significant improvements …

A subspace approach to accelerated cardiovascular magnetic resonance imaging
… on the integration of the subspace model, sensitivity encoding (for parallel imaging), and sparse modeling into one optimization problem; evaluations of strategies for regularizing the image model, adaptively enforcing model order, and for estimating sensitivity maps are also included. The …

On The Origin of Sensory Errors
… cannot be due to the variability during the encoding stage. Further, I show a very close fit between the theoretically generated tuning curve and the behavioral results, which gives more insight into the error generation mechanism. Finally, I find that the time window over which perceptual …

Distortion-optimal parallel MRI with sparse sampling: from adaptive spatio-temporal acquisition to self-calibrating reconstruction
… accounts for speed limitations of gradient encoding, provides performance guarantees on achievable image quality both in terms of noise gain and aliasing distortion, and allows for analysis of the method's robustness to model mismatch. We present in-vivo results demonstrating the feasibility …
