[Insight-users] Access directly to the data structure

[Uril Yakubov]

Hi every-body,
 
I am a new in ITK and I would like to now how I can access directly
image intensities in data structure. I have next code.

For example I read a vtk file: 
    typedef itk::Image< unsigned short, 3 >    ImageType;
    typedef itk::ImageFileReader< ImageType >  ReaderType;
    ReaderType::Pointer reader = ReaderType::New();
    reader->SetFileName( inputFilename  );
    reader->UpdateLargestPossibleRegion();

What should I do next to get value from  coordinate (x,y,z).

Thank you for help.

Uril.
