<br>
<br>
The vtkKWImage and vtkKWImageIO classes are mainly useful for:<br>
<br>
1. read (nearly) all the image formats that ITK can read using vtkKWImageIO -> returns a vtkKWImage, which has the method "GetVTKImage".<br>
<br>
2. at the end of an itk pipeline, pass the itk image to the vtkKWImage object using "SetITKImageBase" and get the vtkImageData for your visualization pipeline.<br>
<br>
<br>
If you want to read an image and pass it to an itkImage for image processing, an itkImageReader is more straightforward.<br>
<br>
<br>
BTW: I am not sure if the vtkKWImageIO class can read Dicom images. I would suggest following:<br>
<br>
1. Read dicom images using an itk reader, which can handle dicom<br>
2. pass itkImage to vtkKWImage<br>
3. pass vtkImageData from vtkKWImage to your viewer (e.g. vtkImageViewer2).<br>
<br>
<br>
If you have 3D images and want to move between slices, and if you maybe even want to select pixels (seed points), then you could use my own image viewer.<br>

Hello<br>
<br>
I am trying to do a simple 2D Dicom series reader and viewer using ITK and VTK.<br>
<br>
Initially I used the itk GDCM class and successfully read a DICOM series and using the itk-vtk imoprter and exporter classes was able to connect the pipelines so that I would write an XML file (VTI) using vtk classes. Then read the vti file and display it in VTK.<br>
<br>
I would prefer to it without writing the XML file. If I use a different than the vtkXMLwriter class, say vtkImageShifScale or vtkImageViewer2 to catch the DICOM stack I get a segmentation fault.<br>
<br>
Recently I found the vtkKWImage and vtkKWImageIO classes and was successfull at reading the DICOM files and connecting them to both vtk classes I mentioned (shifter and viewer). <a href="http://insight-journal.org/dspace/handle/1926/495" target="_blank">http://insight-journal.org/dspace/handle/1926/495</a><br>
<br>
BUT I don't know if I could use an itk filter (say itkCurvatureFlowImageFilter) before displaying them since I only found the "Setfilename" and "Setdirectory" options for the vtkKWImage class.<br>
<br>
Can you use vtkKWImage and vtkKWImageIO in combination with itk Filters?<br>
<br>
If not, is there an explanation for the segmentation fault I get when not using the XML writer?<br>
<br>
Thank you,<br>
<br>
Sergio<br>
