An interactive registration tool that manages viewing and manipulating of sets of fiducials

This is a work-in-progress that will ultimately be an extension or core module of 3D Slicer.

Some background information is here:

http://www.na-mic.org/Wiki/index.php/2013_Summer_Project_Week:Landmark_Registration

To test: You need to checkout two repositories (1) this one and (2) https://github.com/pieper/CompareVolumes

If you checked them out to /tmp, then you can start slicer as follows:

Linux:

./Slicer --additional-module-paths /tmp/CompareVolumes /tmp/LandmarkRegistration

(on windows you run "Slicer.exe " from a console. On mac, you use "open Slicer.app ")

Linear:

• load the two volumes to register
• enter the LandmarkRegistration module
• select Fixed and Moving (do not select transformed)
• scroll to the Registration area and select Linear
• enable the Registration Active checkbox (this will create a transformed volume)
• pick Axi/Sag/Cor in the Visualization box (this will create a custom layout with fixed on top, moving in the middle, and fixed + transformed on the bottom)
• place a fiducial on either the fixed or moving volumes (a corresponding one will be created on the other volume)
• drag the fiducials in the fixed and moving volumes until they are on the same anatomical location. The blended view will update automatically on mouse release.
• place and adjust fiducials until registration is good.
• Option: Similarity mode is Rigid + Scale and can be good for some cross-subject registration

• Affine mode requires more landmarks but should work
• Thin-Plate spline mode works but does not automatically update (click Apply to calculate). It overwrites the transformed volume so you can't go back to Linear mode from Thin-Plate mode).
• Hybrid B-Spline mode is still under development.
