ISMRM 21st Annual Meeting & Exhibition 20-26 April 2013 Salt Lake City, Utah, USA

Bringing Radiation Therapy to the Next Level: Technical Concepts & Clinical Applications of Combined MRI-Radiation-Therapy Systems
SKILL LEVEL: Intermediate to Advanced
ORGANIZERS: Michael Bock, Ph.D. & Tim Leiner, M.D., Ph.D., E.B.C.R.
Tuesday, 23 April 2013
Radiation therapy of moving organs is challenging, as the precise internal motion patterns often cannot be deduced from external anatomical landmarks. To avoid unnecessarily large safety margins and to more precisely target the therapy, real-time imaging of the target structure and the surrounding risk structures is therefore desirable. Recently, several different systems for MR-guided radiotherapy have been proposed which aim to perform the therapy within an MR magnet. In this course, the different technical approaches are presented, and the first clinical results will be shown.
Clinicians and physicists with an interest in oncology and/or hybrid MR systems.

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

  • Identify possible application scenarios for MR image guided radiotherapy;
  • List the three different current technological attempts to perform a combined MR radiotherapy; and
  • Describe the advantages and challenges of a combined RT-MR approach.
