[Insight-users] 2D slice registration

[frankmiller at jhmi.edu]

Hi Susie,

The important steps to perform 2D slice to 3D volume registration in ITK
are as follows:

  * Represent the 2D slice as a 3D image with size [width,height,1]
  * Set the slice as the fixed image.
  * Set the volume as the moving image.

Also, make sure you are using itk::OrientedImage to properly represent
the initial orientation of the oblique slice.

I can't speak on your specific application but I suspect it will work
fine if you pick the right metric.

Good luck,

Frank

Caveat: Each subject's EPI axial slice was taken parallel to his/her specific hippocampal longitudinal axis and the angle is unknown.  Therefore, I have a low-res 2D axial slice at an unknown angle and a high-res 3D MPRAGE.
