<DIV class=WordSection1>
<P class=MsoNormal>Dear All,<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I have succeeded in loading a series of DICOM images and
visualized them by VTK. However, I can just see the last DICOM file. What I
want is that through controlling the scroll of the mouse, I can navigate from
one slice to another slice. Does anybody know how to fulfill the
goal?<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Attached please find my code.<o:p></o:p></P>
