<p class="MsoNormal">Hi slicer,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am developing a module in Slicer and I found a bug in vtkITKArchetypeImageSeriesReader class. Here is the issue.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Since dicom utilizes the concept of slope and intercept, the scalar range for each 2D slice can be much different. However, in Slicer, the scalar type is determined by checking the ComponentType returned by GDCMImageIO which only tells
the last slice ComponentType in vtkITKArchetypeImageSeriesReader.cxx. <br>
<br>
I propose to change vtkITKArchetypeImageSeriesReader.cxx as well as the itkImageSeriesReader class in ITK. The idea is that the scalar range will be checked for each 2D slice in itkImageSeriesReader and then a new variable OutputImagePixelScalarType will be
set accordingly, then in vtkITKArchetypeImageSeriesReader.cxx it will check the OutputImagePixelScalarType from the itkImageSeriesReader to correctly determine the scalar type. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If you think this makes sense, I will create an ITK ticket and submit a patch to ITK. The slicer patch has to wait until slicer start to use the newly patched ITK. I have created a ticket for tracking this:
