Summary0000107: registration result is wrong (due to origin issue with itk's OrientImage filter
Description

When you run the registration filters in slicer3 the output volume data is translated away from the correct answer. See the images in the attached screen shot.

Steps To Reproduce

Use the fixed.nrrd and moving.nrrd files in Slicer3/Lib/MRML/Testing/TestData.

Run the LinearRegistration with default options. Registration answer will appear to be correctly rotated, but switching background volume to "fixed" will show a blank screen (because the two volumed don't overlap).

Note that the slicer 2D viewers auto-center on the newly loaded registration result. In order to get the view to center on the current background image you need to click on the Fit Field of View button for the slice viewer (button to the right of the eyeball).

Additional Information

Jim and I tracked this down to the origin being incorrectly calculated in the OrientImage code in ITK.

The itkOrientImageFilter is not computing the origin correclty for Oriented Images. This is causing incorrect registraion results in all registration plugins for volumes that are not axial.

A helper function, AlignVolumeCenters has beed added to itkPluginUtilities.h. This function computes an origin that aligns the centers of a fixed and moving volume. The Linear, Affine and Deformable BSpline registration plugins are being tested with this new function.
