[Insight-users] How to specify transform parameters

[Andrew Li]

Dear ITK users:

I am planning to use "itkResampleImageFilter" 
for data reorientation from Axial to Coronal without shifting.


	// Moving dataset: 3D Axial: 
	//            row(L->R):   1.0,  0.0,  0.0
	//            col(A->P):   0.0,  1.0,  0.0
	//           norm(F->H):   0.0,  0.0,  1.0
	//

Moving: Spacing [1.01562, 1.01562, 3]
Moving:  Origin [-130, -130, -75]
Moving:    Size [256, 256, 50]
Moving:   Index [0, 0, 0]

	//
	// Fixed dataset: 3D Coronal: 
	//            row(L->R):   1.0,  0.0,  0.0
	//            col(H->F):   0.0,  0.0, -1.0
	//           norm(A->P):   0.0,  1.0,  0.0
	//
Fixed:  Spacing [1.01562, 1.01562, 1.59999]
Fixed:   Origin [-130, -130, -127.999]
Fixed:     Size [256, 256, 160]
Fixed:    Index [0, 0, 0]

I assume that I could use the following transform type:

typedef itk::VersorRigid3DTransform< double  > TransformType;
typedef TransformType::ParametersType          TransformParametersType;
typedef TransformType::InputPointType          TransformCenterType;

Question #1: How to set transform parameters? There are 6 of them. 
Question #2: I assume I should set transform center 
	to: {0,0,0}. Is it correct?

Thank you all very much in advance.
