Motion Correction in MRI
Tromsø, Norway



The Motion Correction in MRI workshop will follow up on the highly successful “Current Concepts of Motion Correction for MRI & MRS” workshop, held in February 2010, in Kitzbühel, Austria.

Motion has been a problem for essentially all types of MR acquisitions since the beginning of clinical MRI.
Many motion correction and prevention techniques have been proposed over the years, ranging from rigid-body or elastic retrospective correction, gated acquisition, to various forms of prospective motion correction using either the MR signal itself or by tracking using external systems, such as cameras.

This workshop will have very didactic and hands-on presentations from the keynote speakers. We will also have a hands-on Matlab session, where the attendees will be able to do image realignment exercises in Matlab using their own laptops. This will involve creating functions for image transformation, cost functions and search algorithms, test them for different data, and put it all together to a working image realignment tool. Example data and Matlab scripts necessary for the exercises will be available on the workshop web site.

In addition, we note that despite the increased focus on motion correction over the last few years, only a very small subset (incl. e.g. PROPELLER) of these are used in the average hospital or have been commercially implemented. Therefore, the gap between research and commercial implementation will also be a part of the discussion on this workshop.



This workshop is designed for:
  • New MR scientists who would like to get a hands-on experience and a good introduction to various motion correction techniques;
  • Experienced MR scientists currently developing motion correction techniques and interested in alternative solutions; and
  • Clinicians interested in applying the latest correction methods to solve their motion problems.


Workshop attendees will gain an understanding of:
  • Recognize state-of-the art motion robust acquisition methods and assess if they can be implemented in their practice;
  • Assess the strength and limitations of various prospective and retrospective motion correction methods;
  • Implement a simple retrospective motion correction program based on the examples given in the workshop;
  • Relate their own research on motion correction with alternative methods presented and use this knowledge to prioritize their next steps in the field;
  • Recognize differences in motion artifacts for various image acquisition methods; and
  • Distinguish between different methods for motion correction recently made available and understand under what circumstances they may be used.
