[Insight-users] Changing itk.Examples.Registration.Translation1.cs to work with 3d images

[Carl Bateman]

I'm trying to change itk.Examples.Registration.Translation1.cs to work with 3d images.

I've changed the existing using statements to:
  using ImageType = itk.itkImage_UC3;
  using InterpolatorType = itk.itkLinearInterpolateImageFunction_IUC3D;
  using TransformType = itk.itkTranslationTransform_D3;
  using ResampleType = itk.itkResampleImageFilter_IUC3IUC3;
  using MetricType = itk.itkMeanSquaresImageToImageMetric_IUC3IUC3;
  using OptimizerType = itk.itkRegularStepGradientDescentOptimizer;
  using RegistrationType = itk.itkImageRegistrationMethod_IUC3IUC3;

and the transform.Translate lines to:
  transform.Translate(new itkVector(7.0, 12.0, 0.0));
and
  transform.Translate(new itkVector(0.0, 0.0, 0.0));


I'm using a raw image with a mhd header as input.

The original image has 128 slices, but the "_FIXED", "_MOVING" and "_REGISTERED" images only have 64 slices.

Additionally, the "_MOVING" and "_REGISTERED" images have a white cross through them (see attached png).

I suspect that the problem lies in the transformation, as 
  transform.Translate(new itkVector(7.0, 0.0, 0.0));
gives a horizontal line, while 
  transform.Translate(new itkVector(0.0, 12.0, 0.0));
gives a vertical line.


Is it the transformation? And if so how should it be used correctly?

Any help appreciated.
