<p class=MsoNormal>Hi,<br>
<br>
I am trying to recursively read all dicom images from a CT study with several
series. How do I figure out which images are real/primary&nbsp; scans(where the
x-ray beam was ON) and which ones are not( such as recons, etc.)? I have been
looking at the Image Type Tag(0008,0008) and series description tag
(0008,103E), but is there a more systematic and foolproof way of figuring this
out?<br>
<br>
This may not exactly be a VTK/GDCM question, but since there are many dicom
experts in the community, if anyone can guide me, I would really appreciate it.<br>
<br>
Thanks,<br>
Ashish<o:p></o:p></p>
