<DIV>Maybe the order in which the scans were reconstructed were in opposite order? This could happen if, for example, the patient orientation was not set correctly in the scanner. An example would be the patient was feet first supine but the technologist left the default head first supine setting. Also, on some scanners I think it may be possible to reconstruct in either order. One dicom tag you can look at is InstanceNumber (0020,0013) and see how the slices are numbered.</DIV>

<P>Hi to all !</P>
<P>I have done a CT viewer with MPR guided of this example:</P>
<P><A href="http://www.vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/Medical/Cxx/Medical3.cxx" target=_blank>[VTK.git] / Examples / Medical / Cxx / Medical3.cxx</A></P>
<P>The only difference is that I have used <A href="https://github.com/dgobbi/vtk-dicom" target=_blank>vtkDICOMReader</A> as DICOM reader, it's the only difference ...</P>
<P>but I noticed that on <EM>axial planes</EM>, the original plane, <EM>the slice numbering begin with 1 from the top of the patient, and of some of them the slice numbering are finish on the top of the patient</EM> ... </P>
<P>Can you tell me why is happen that, and how can I solve the problem ? Any hint, link, solution would be very appreciated !</P>
<P>Flaviu.</P></DIV></BLOCKQUOTE></DIV></DIV></DIV><BR></DIV></DIV></BODY></HTML>
