The chapter highlights the problems with standard approaches, such as diffusion-tensor MRI, to motivate a recent set of alternative approaches. The review concentrates on the software implementation of the new techniques. Results of the preliminary comparison show that PASMRI recovers the principal directions of simple test functions more consistently than q-ball imaging and produces qualitatively better results on the test data set. Further simulations suggest that a moderate increase in data quality allows q-ball, which is much faster to run, to recover directions with consistency comparable to that of PASMRI on the test data. date: 2005-12 publisher: NEW YORK ACAD SCIENCES official_url: http://dx.doi.org/10.1196/annals.1340.018 vfaculties: VENG oa_status: green full_text_type: pub primo: open primo_central: open_green article_type_text: Proceedings Paper verified: verified_manual elements_source: Web of Science elements_id: 32488 doi: 10.1196/annals.1340.018 language_elements: EN lyricists_name: Alexander, Daniel lyricists_id: DALEX06 full_text_status: public publication: WHITE MATTER IN COGNITIVE NEUROSCIENCE: ADVANCES IN DIFFUSION TENSOR IMAGING AND ITS APPLICATIONS volume: 1064 pagerange: 113 - 133 event_location: New York Acad Sci, New York, NY issn: 0077-8923 editors_name: Ulmer, JL editors_name: Parsons, L editors_name: Moseley, M editors_name: Gabrieli, J citation: Alexander, DC; (2005) Multiple-fiber reconstruction algorithms for diffusion MRI.
