Image Reconstruction
ORGANIZERS: Elfar Adalsteinsson, Ph.D. & Kawin Setsompop, Ph.D.
SKILL LEVEL: Intermediate
Tuesday - Friday, 10-13 May 2011

This four-hour course over four mornings will provide an in-depth review of the fundamental concepts common to many image reconstruction problems in MRI. MRI scientists from industry and academia will provide lectures on non-Cartesian image reconstruction, off-resonance correction, parallel imaging with Cartesian and non-Cartesian data sampling, emerging sparse data methods, and chemical shift and motion. These courses are intended to introduce new researchers to the advanced algorithms employed in state-of-the-art systems. Each morning, the course will be organized, as a set of two 25 minute lectures, each with 5-minute discussion periods.
Upon completion of this course participants should be able to:
Describe the main steps involved in efficient non-Cartesian image reconstruction;
Formulate a generalized signal model incorporating gradient encoding, coil sensitivity and Bo inhomogeneity;
List the pros and cons of Cartesian and non-Cartesian parallel MRI;
Compare compressed sensing, HYPR, and k-t BLAST with respect to their use of prior knowledge;
Describe the principles of separating water and fat signals; and
Name three different approaches for motion correction and appraise their potential to become routine methods.
