Hi Lodron,
the method Image::InitializeByItk can't extend or change the dimensionality of
the image. So with the call
mitkImage->InitializeByItk( SomeITK-3D-Image, ...)
the mitkImage will have the same dimensionality ( i.e. 3 ) and also same
dimension sizes. The remaining parameters in the function definition can
change the corresponding dimension size but ONLY if the dimension is available
in the given input image.
Solution for your problem is to create an mitk::Image with 4 dimensions, and
also initialize it with a TimeSlicedGeometry:
Could look like:
mitk::Image::Pointer image4D = mitk::Image::New();
mitk::TimeSlicedGeometry::Pointer geom = mitk::TimeSlicedGeometry::New();
geom->InitializeEvenlyTimed( m_VectorOf3DImages[ 0 ]->GetGeometry(),
m_VectorOf3DImages.size() );
Regards,
Jan

Betreff: [mitk-users] 4D image initialization form itk 3d image stack
Hi
I try to make a 4d mitk image form a stack of 3d itk images (gray), can anyone
tell me what i am making wrong:
Std::vector<itk::Image<unsigned short, 3>::Pointer> o3DImageStack;//my filled
itk image array
mitk::DataNode::Pointer oNode = mitk::DataNode::New();
mitk::Image::Pointer oImage = mitk::Image::New();
oImage->InitializeByItk(o3DImageStack.at(0).GetPointer(),1,o3DImageStack.size());
for(unsigned int i=0; i<o3DImageStack.size(); i++)
{
oImage->SetVolume(o3DImageStack.at(i)->GetBufferPointer(), i);
}
oNode->SetData(oImage);
oDS.Add(oNode);
In the mitk GUI the image has only 1 time step in timeslicedgeometry
Best regards
