[Insight-users] Writting DICOM Images

[Mathieu Malaterre]

Rodolfo,

	Ok this is really a problem. Your DICOM file does not even have 
dimensions. But this is clearly specify in itkGDCMImageIO(*)

	Could you tell me which ITK version are you using. In particular the 
revision at the top of file itkGDCMImageIO.cxx

                    ...
                    Version:   $Revision: 1.74 $
                    ...

Thanks
Mathieu
(*)
   // Handle the dimension of image:
   itksys_ios::ostringstream str;
   str << m_Dimensions[0];
   header->InsertValEntry( str.str(), 0x0028,0x0011); // Columns

   str.str("");
   str << m_Dimensions[1];
   header->InsertValEntry( str.str(), 0x0028,0x0010); // Rows

   if(m_Dimensions[2]>1)
   {
      str.str("");
      str << m_Dimensions[2];
      //header->Insert(str.str(),0x0028,0x0012); // Planes
      header->InsertValEntry(str.str(),0x0028,0x0008); // Number of Frames
   }
