ISMRM 23rd Annual Meeting & Exhibition 30 May - 05 June 2015 Toronto, Ontario, Canada

RF Engineering: Coils
SKILL LEVEL: Intermediate
ORGANIZERS: Nicola F. De Zanche, Ph.D. & Graham C. Wiggins, D.Phil.
Sunday, 31 May 2015
In this one-day course, the principles of RF coils used to detect and excite the MR signals will be discussed, beginning with the transmission lines that interconnect the coils to the MR system, and extending to single surface and volume coils and finally RF coil arrays for both transmit and receive. A discussion of the RF modeling tools used to analyze these coils and coil arrays, and their interaction with the patient and the environment will lead into the interaction of RF fields with other objects in the MR environment. The course will conclude with a live demonstration (or by video and live commentary) of the construction and tuning of RF coils for humans and animals.
MR technicians, medical physicists, scientists and engineers with an interest in understanding physical principles behind MR safety issues related to RF fields, and/or the construction, design or use of RF coils and RF coil arrays.

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

  • Describe the basic theory, design and construction of single and multi-tuned RF coils and their feed networks;
  • Illustrate the principles of operation and basic applications of receive and transmit RF coil arrays; and
  • Compare the major methods of RF modeling commonly in use and the relative advantages and disadvantages of each.
