<DIV>Dear Jon,</DIV>
<DIV>    Thanks for your reply.</DIV>
<DIV>    I only specified pixel type in the this line(typedef itk::Image<unsigned char,2> ImageType;),and after receiving your reply, I changed it to unsigned short, short, and signed short which was not working unfortunately.</DIV>
<DIV>    Have any other thoughts about it?</DIV>

<DIV dir=ltr>Dear Guirong,
<DIV>
<DIV>
<DIV>DICOM images most commonly use short pixel types.</DIV></DIV>
<DIV><BR></DIV>
<DIV>The error says that there is some problem with the pixel type you specified.</DIV></DIV>

<DIV>Hi,everyone,</DIV>
<DIV>     I'm using ITK to read CTA image(it's a kind of dicom image),and when it runs to the update ,the following error happens:</DIV>
<DIV>
<DIV>
<DIV> in command line:Assertion failed:pixeltype_debug==pixeltype.  file..\..\..\..\..\InsightToolkit-4.4.0\Modules\IO\GDCM\src\itkGDCMImageIO.cxx,line 287</DIV>

<DIV>in a window:</DIV>
