[vtkusers] vtkImageReslice and orientation

[Emmanouil Moschidis]

Hello 
due to a bug related to my DICOM viewer when I read a study I orient the slices axially. As a result when I try to reslice the volume I get sagital instead of axial slices, sagital instead of coronal and coronal instead of axial... (the original orientation of the study was sagittal and I made it axial)

so I thought I should just rotate the resliceAxes accordingly but it seems that is not the correct idea. This is what I am doing 

    vtkTransform *rotator=vtkTransform::New();
    rotator->PostMultiply();
    rotator->Translate( -(origin[0] + spacing[0]* coords[0]) , -(origin[1] + spacing[1]*coords[1]), -(origin[2] + spacing[2]*coords[2]) );
    rotator->RotateX(-90);
    rotator->RotateY(-90);
    rotator->Concatenate(coronalElements);
    rotator->Translate( (origin[0] + spacing[0]* coords[0]) , (origin[1] + spacing[1]*coords[1]), (origin[2] + spacing[2]*coords[2]) );
    rotator->Update();

    reslice->SetResliceAxes(rotator->GetMatrix());


Any Idea? Thanks
