[Insight-users] CT /MR Fusion

[Bill Lorensen]

You do not have to resize the data. itk's registration algorithms
works in physical units. You may have to align the centers of the 2
volumes, unless they were landmarked the same during acquisition.

For multimodal fusion we normally use Mattes Mutual Information.
Several examples use it. You can search Examples/Registration.
However, parameter setting can be tricky.
