MR Engineering

Organizers: Mark Griswold, Ph.D.; Brian Rutt, Ph.D.
Skill Level: Basic - Advanced

Saturday, 3 May 2008 - Sunday, 4 May 2008


This two-day course will provide an in-depth, practical description of fundamental concepts of MR engineering, covering the physics and engineering challenges associated with MRI hardware design for both current and future MRI.

The first day will cover primarily magnets, gradients, and shims, while the second day will cover mostly RF related topics.  Methods to characterize the system at all levels wukk also be covered, as well as compliance regulations in MR engineering related areas (e.g. ISO, FDA, CE).

Educational Objectives:

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

  • Recognize all of the basic hardware components of an MRI scanner and understand how they are related;
  • Describe the basic methods for magnet, gradient and shim design;
  • Identify common magnet, gradient and shim imperfections;
  • Describe the basic types of RF coils and how they are constructed;
  • Describe the basic methods one can use to model an RF coil and its effects in the human body, such as heating; and
  • List and describe the basic compliance and regulatory bodies that deal with MR hardware.

    Audience Description:

    This course is designed for basic scientists, engineers or physicians (MS, Ph.D., and/or M.D., doctoral candidates) with knowledge of basic MR physics and engineering.  Scientists or engineers developing or using state-of-the-art MRI/MRS hardware will find it useful.
