[Insight-users] Non-planar slicing

[somi]

Hi,
I think one way to compute what you want is to :

a) Create a surface of the non-planar manifold that you desire ( I assume
its parametric to that should be easy to do)
b) Voxelize the surface it into an image
c) Use the image created in step (b) as a mask and perform an AND operation
with your image

The voxeliztion process might be slow if you create a finely spaced volume.

Thanks,
Somi

I need to extract a 2D image from a 3D data set by what I would call
non-planar slicing. Imagine a sheet of paper curled into a parabola or
half-ellipse, in the middle of a 3D volume. I want to extract the points on
the sheet of paper into a flat 2D image. (If there is a better/standard term
for this, please correct me). The curve would be defined by a poly-line or
Bezier.

AFAICT, the closest thing in ITK is ResampleImageFilter(), however I'm
having trouble figuring out what the transform would be. All the examples
seem to map 3D to 3D. Or is this the wrong approach to begin with?

Can anyone point me at something similar?
