Sunrise Course:
Image Reconstruction
Organizer: Elfar Adalsteinsson, Ph.D.
 
Skill Level: Intermediate - Advanced
Tuesday - Friday, 4-7 May 2010
07:00 - 08:00

OVERVIEW
This 4-hour course 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 speak on non-Cartesian image reconstruction, off-resonance correction, parallel imaging, emerging sparse data methods, and chemical shift and motion. These sessions are intended to introduce new researchers to the advanced algorithms employed in state-of-the-art systems. The course consists of four 1-hour sessions, and each of the eight lectures will be followed by an opportunity for questions.
 
EDUCATIONAL OBJECTIVES
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 proís and conís 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.
