<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m using vtk 5.4.2 on a windows platform.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve got a number of DICOM series which are being read
by vtkDICOMImageReaders. Now I need to register them and average the
pixel values. For now I’m just adding translations to the origins and
connecting them to a vtkImageWeightedSum object. The issue is that my translations
don’t seem to have an effect.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve tried connecting the vtkDICOMImageReader ->
vtkImageChangeInformation -> vtkImageWeightedSum and
vtkDICOMImageReader->vtkImageReslice->vtkImageWeightedSum. Neither
of which worked. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Looking at the source code for vtkImageWeightedSum, I guess
it makes sense because it is doing a voxel by voxel summing and not taking the
spatial location of the pixels into account.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is there a way to do this in vtk or do I need to incorporate
some itk?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
