[Insight-users] How to convert SimpleITK image to VTK data

[Bradley Lowekamp]

Hello,

I have not tried this, but you should be able to convert the sitkImage into a numpy array and them import that into VTK. To get a numpy ndarray from simpleITK try the following:

import SimpleITK as sitk
import numpy as np

sizeX, sizeY, sizeZ = 100,100,100

image = sitk.Image( sizeX, sizeY, sizeZ, sitk.sitkFloat32 )

nparray = sitk.GetArrayFromImage( image )

Then on the VTK side the following example looks like it should do the trick, using vtkImageImport and numpy arrays:

As I said I have not tried this my self so please let us know if this work for you. Additionally, this approach will create a couple of copies during the transition.
