[Insight-users] GDCM Series Dicom reader for some Siemens MRI Dicom data

[Andrew Li]

Dear ITK users:

This is a brief report about an instance reading Siemens MRI DICOM data:
VB33G, MAGNETOM VISION;

Our program crashed at ImageReader->Update() without catching any
exception thrown.
 
The problem is tracked down to this section in
Insight/Utilities/gdcm/src/gdcmDocument.cxx

   //////// Fix for some brain-dead 'Leonardo' Siemens images.
   // Occurence of such images is quite low (unless one leaves close to
a
   // 'Leonardo' source. Hence, one might consider commenting out the
   // following fix on efficiency reasons.
   //
   else if ( gr   == 0x0009 && ( elem == 0x1113 || elem == 0x1114 ) )
   {
      foundLength = 4;
      entry->SetReadLength(4); // a bug is to be fixed !
   } 

The problem is gone when I commented out this section.

It seems to me that the original problem in the headers is fixed and
this section that handles the original problem is not compatible with
new headers.
