void main( )
{
  typedef signed short InputPixelType;
  const unsigned int   InputDimension = 2;


  typedef itk::Image< InputPixelType, InputDimension > InputImageType;


  typedef itk::ImageFileReader< InputImageType > ReaderType;


  ReaderType::Pointer reader = ReaderType::New();


  const char * filename = "C:\\Users\\zhq\\Desktop\\data\\SNAP_CR\\E403434298\\E403434298S1901I301.dcm";
