> Title:   "New Methods in Medical Image Registration"
>
> Abstract:
>
> Image registration is the task of aligning two or more images so that
> their content corresponds on a pixel-to-pixel basis.  In this two-part
> talk, I will discuss two of my recent projects in automatic image
> registration.
>
> Part 1: Most image registration methods assume that the images being
> registered are nearly aligned.  When that's not the case, things fall
> apart.  I have developed a method that efficiently combats this
> problem by exhaustively considering all possible shifts of an image.
> It's made possible by some FFT trickery.
>
> Part 2: When registering medical images of different types (eg. MRI
> and a CAT scan), the images cannot be registered using pixel
> intensities directly.  For example, bones are bright in a CAT scan,
> but dark in an MRI.  Instead, the problem is often formulated in
> information-theoretic terms, yielding the current state-of-the-art
> method of Mutual Information.  However, I will demonstrate that there
> are advantages to posing the problem in terms of clustering.

> Bio:
>
> Jeff Orchard received his B.Math. degree in applied mathematics from
> the University of Waterloo, Canada, in 1994, and his M.Sc. degree in
> applied mathematics from the University of British Columbia, Canada,
> in 1996.  He received his Ph.D. degree in computing science from Simon
> Fraser University, Canada, in 2003.
>
> Since 2003, Prof. Orchard has been an Assistant Professor in the David
> R. Cheriton School of Computer Science at the University of Waterloo,
> Canada.  His research interests revolve around applying mathematics
> and computation to visual data.  He has worked on projects in image
> registration, motion compensation for medical imaging, functional MRI,
> medical image reconstruction, and image mosaicking.  At the University
> of Waterloo, he is affiliated with the Scientific Computing Research
> Group, the Waterloo Institute for Health Informatics Research, and the
> Centre for Computational Mathematics in Industry and Commerce.  In
> 2005, Prof. Orchard organized a workshop called the "Grand
> Mathematical Challenges in Medical Image Processing".
> I hope to see you all there.
