Commercial receivers used for parallel MR imaging often present researchers with hurdles such as high cost-per-channel, low scalability for multiple coils and non-accessibility to intermediate data for research. A novel low-cost multichannel digital receiver for use with MR scanners has been developed to alleviate these concerns. MR signals from up to 16(More)
Acknowledgments I would like to thank my advisor, Dr. Fred Fontaine, for his guidance and patience throughout this process. Without his teachings I would not be where I am today. I would also like to thank the rest of the faculty, as well as my friends and peers at The of whom gave their time to listen patiently to my ideas and help me improve this thesis(More)
— Common MRI sampling patterns in k-space, such as spiral trajectories, have nonuniform density and do not lie on a rectangular grid. We propose mapping the sampled data to a pseudo-hex lattice, taking advantage of its approximate isotropic nature in k-space and square nature in the reconstructed image space. The group structure of the lattice is exploited(More)
guidance during the preparation of this thesis. Mr. Henry Massalin supplied the GIF decoder used, answered many questions, and in general was a good influence on me. Dr. Leonid Vulakh helped with some of the theory. I would also like to thank the Cooper Union librarians for tracking books down for me and also furnishing many of the pictures used in the(More)
