Download or read book Compressed Sensing for Diffusion MRI of the Mouse Brain written by Anthony Salerno and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffusion magnetic resonance imaging (MRI) uses loss of signal coherence caused by movement of water molecules to determine how water diffuses in tissue. These scans are known to take a significant amount of time owing to the repeated acquisition of images, each measuring diffusion for a particular direction and weighting. Emerging methods based on collection of increasingly large numbers of diffusion directions and/or weightings promise to provide a more detailed characterization of brain microstructure than previously possible. However, because the time required for these methods can render them impractical, I present a method of acquiring and reconstructing diffusion MRI data based on compressed sensing (CS) that enables flexible trade-off between spatial sampling and diffusion direction/weighting sampling. This method enables the collection of more diffusion data in a given scan time at the cost of extended reconstruction time.

This book was released on 2015 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective techniques of inferring the condition of neural tracts in the brain is invaluable for clinicians and researchers towards investigation of neurological disorders in patients. It was not until the advent of diffusion Magnetic Resonance Imaging (dMRI), a noninvasive imaging method used to detect the diffusion of water molecules, that scientists have been able to assess the characteristics of cerebral diffusion in vivo. Among different dMRI methods, High Angular Resolution Diffusion Imaging (HARDI) is well known for striking a balance between ability to distinguish crossing neural fibre tracts while requiring a modest number of diffusion measurements (which is directly related to acquisition time). HARDI data provides insight into the directional properties of water diffusion in cerebral matter as a function of spatial coordinates. Ideally, one would be interested in having this information available at fine spatial resolution while minimizing the probing along different spatial orientations (so as to minimize the acquisition time). Unfortunately, availability of such datasets in reasonable acquisition times are hindered by limitations in current hardware and scanner protocols. On the other hand, post processing techniques prove promising in increasing the effective spatial resolution, allowing more detailed depictions of cerebral matter, while keeping the number of diffusion measurements within a feasible range. In light of the preceding developments, the main purpose of this research is to look into super resolution of HARDI data, using the modern theory of compressed sensing. The method proposed in this thesis allows an accurate approximation of HARDI signals at a higher spatial resolution compared to data obtained with a typical scanner. At the same time, ideas for reducing the number of diffusion measurements in the angular domain to improve the acquisition time are explored. Accordingly, the novel method of applying two distinct compressed sensing approaches in both spatial and angular domain, and combining them into a single framework for performing super resolution forms the main contribution provided by this thesis.
