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.
