<DIV><FONT face=Arial>Hi Miller,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Thank your help!</FONT></DIV>
<DIV><FONT face=Arial>Like you said, I change the itk::DicomimageIO to the
itk::DICOMImageIO2 then obtain the correct spacing between the two slices.
However, the origin is -124.500000\ -116.099998\-35.299999237060 instead of the
0\0\0 obtained by the itk::DicomimageIO. In my opinion, the 0\0\0 may be the
default value of the itk::DicomImageIO. What I can not be sure is that can I use
the patient Position as the origin? Why I can not found the Z
coordinate "-35.299999237060" in all the tag?</FONT></DIV>
