[Insight-users] Interpolation Volume

[Luis Ibanez]

Hi  Gupt,


Yes, just do the following:


A) Load the 2D slices into a single 3D image using the
     itk::ImageSeriesReader,


B) Connect the image an ImageInterpolator
     The typical choice is the itkLinearImageInterpolateFunction class,
     (but you can also use NearestNeighbors, BSpline and
      WindowedSinc, it is a trade-off between computation time and
      interpolation precision)


C) Take all the points from your surface model and for every
     point call the method:

       PixelType  pixelValue =    Interpolator->Evaluate( point )

    and then assign that pixel value to the corresponding point
    in the surface model.



  Please let us know if you run into any problem.


       Thanks


          Luis
