Imaging Strategies

Organizers: James G. Pipe, Ph.D., Walter F. Block, Ph.D., Brian A. Hargreaves, Ph.D.
Skill level:  Intermediate

Sunday, 4 May 2008


This one-day course will cover methods important for people who want to design or understand imaging pulse sequences. It is meant to be a companion course to "MR Physics for Physicists," which will be held the day prior. This course is composed of 13 30-minute talks grouped into four sessions: General Pulse Sequence Strategies, Pulse Sequence Tools, Rapid Pulse Sequence Tools, and Highly Accelerated Imaging.

Educational Objectives:

Upon completion of this course, participants should be able to:

  • Give examples of different data collection strategies, and their uses;
  • Design pulse sequences for a given application, with the desired contrast;
  • Explain methods for rapid spectroscopic imaging, and how they differ from conventional CSI;
  • Explain the different methods of acceleration, and their advantages and disadvantages; and
  • Identify the basic differences between conventional and more recent methods of image reconstruction (e.g. iterative and non-linear methods).

    Audience Description:

    This course is primarily designed for engineers, scientists, and clinicians who have an interest in understanding, implementing, and refining data collection and reconstruction methods in MRI and MRS. Participants should have a basic understanding of the data collection and reconstruction framework (e.g. T1 and T2 weighting, RF excitation, k-space, Fourier transforms). Participants will come from both academic and industrial settings, as well as governmental and non-governmental research organizations.
