Sunrise Course:
Image Reconstruction
Organizers: Peter Börnert, Ph.D., Klaas Pruessmann, Ph.D., and Jeffrey Tsao, Ph.D.
Skill Level: Intermediate
Tuesday, 21 April 2009 - Friday, 24 April 2009
07:00 - 08:00

This four hour course is designed for attendees with an interest in the workings and capabilities of contemporary MR image reconstruction, and is dedicated to recent advances and directions in this field. Its eight lectures are grouped around the general themes of extended encoding models, sparse sampling, and prior knowledge. Specifically, they will address the principles and practice of fast non-Cartesian reconstruction, B0 inhomogeneity correction, parallel imaging, sparse sampling, water-fat imaging and motion correction.
Upon completion of this case based session, 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 B0 inhomogeneity;
  • List the pro’s and con’s 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.
