[Insight-developers] Mutual Information Registration

[Bill Lorensen]

Folks,
I'm happy to report that I have had success using the Rigid Mutual Information code. The recent changes made by Lydia and a better understanding of the process have made the difference.

I've been able to register about 10 MRI datasets of Alzheimer studies. The results look qualitatively very good. I've yet to quantify the results.

I am not using the new multi-res framework. I'm doing the multi-res myself. I'll report on my experience at the upcoming developers meeting.

My application uses a vtk pipeline that exports to the itk registration classes. Then I convert the resulting quaternion to a 3 x 3 matrix that I pass back into a vtk pipeline for display.

I believe this shows one way that users will be using itk... to get at a particular algorithm.

Thanks Lydia!

Bill
