[Insight-users] WG: RE: Cropping Problem

[Yusuf OEZBEK]

Hello, 



Here are the outputs/results for volume rendering, marching cubes, watershed and region growing segmentation. After the segmentation (in itk) i have the .mhd files saved for both segmentations (watershed and region growing). After this I wanted to the results load into ParaView. But in both files are nothing to see and always get the errors
"ERROR: In .. \ .. \ .. \ src \ server \ Filters \ vtkTexturePainter.cxx, line 287 vtkTexturePainter (00000000082D23E0): Incorrect dimensionality. " and 
"ERROR: In .. \ .. \ .. \ src \ VTK \ IO \ vtkMetaImageReader.cxx, line 105 vtkMetaImageReader (00000000123D7000): Unknown data type: 11 "



Outputs of  "reader->GetOutput()->Print( std::cout );"

and the .mhd Files

All as .zip

Thank you.

Hi Yusuf,


You should start by separating the segmentation
problem from the visualization problem.


Please do the following:

0) Just after you call:

   reader->SetFileNames( fileNames );
   reader->Update();

   add

   reader->GetOutput()->Print( std::cout );

   then

1) Run the ITK segmentation pipeline until you 
    get the segmented image, and save it as a
    MetaImage file (with extension .mhd)


2) Post the content of the resulting .mhd file 
    back to the list, as well as the print out of 
    the statement:

   reader->GetOutput()->Print( std::cout );


3) Use Paraview (www.paraview.org) to load the
    resulting image and extracting an iso-surface.
    Compare that iso-surface with the one that 
    you get by directly from the DICOM image.
    (and let us know what you find).


With the information from (2) we should be 
able to identify if any geometrical information
is missing from the ITK processing pipeline.


   Thanks


         Luis
