[vtkusers] [Insight-users] ITK Dicom imagedata to VTK imagedata

[Sercani]

Isn't there any other way to convert directly
itk::ImageSeriesReader->getOutput() to vtkImageData? I've seen some filters
for this process but I'm not sure about how to use them...

You could also used directlry:

vtkGDCMImageReader.
