Kenny:

You could use vtkImageReslice to compute MPR's.

The class is capable of taking in a transform (see SetResliceTransform) to
resample an image. You could construct a vtkCylindricalTransform and set it
as the resample your image using the transform.

Then extract a slice, again using vtkImageReslice. See
SetResliceAxesDirectionCosines. This should produce your cylindrical MPR.

----
It would be nicer to have a curved MPR widget though in VTK, where the curve
is specified via landmarks. We do see potential applications in dental
imaging.
