Hi Xiaopeng,<br><br>When performing visualization with VTK you must<br>place the camera in the correct position with <br>respect to the data.<br><br>See:<br><a href="http://www.itk.org/Wiki/Proposals:Orientation#C.7.6.2.1.1_Image_Position_And_Image_Orientation">http://www.itk.org/Wiki/Proposals:Orientation#C.7.6.2.1.1_Image_Position_And_Image_Orientation</a><br>
<br>and see the code in IGSTK:<br><a href="http://public.kitware.com/cgi-bin/viewcvs.cgi/Source/igstkView2D.cxx?root=IGSTK&view=markup">http://public.kitware.com/cgi-bin/viewcvs.cgi/Source/igstkView2D.cxx?root=IGSTK&view=markup</a><br>
<br><br>Also, a quick and dirty solution is to use<br>the itkFlipImageFilter, but that is NOT<br>the safe way of displaying medical data.<br><br>instead,<br>You should place the vtkCamera in the<br>correct location and with the correct Up<br>
orientation.<br><br><br><br> Regards,<br><br><br> Luis<br><br><br>--------------------------------------------------------------------------------<br><div class="gmail_quote">On Fri, Oct 15, 2010 at 9:04 PM, Xiaopeng Yang <span dir="ltr"><<a href="mailto:yxp233@postech.ac.kr">yxp233@postech.ac.kr</a>></span> wrote:<br>

<p class="MsoNormal">How are you doing?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">For visualizing DICOM CT images, I programmed like this:</p>
<p class="MsoNormal"> </p>
<p><span>1.<span style="font: 7pt "Times New Roman";">
</span></span>Use ITK reader to load a series of images</p>
<p><span>2.<span style="font: 7pt "Times New Roman";">
</span></span>Apply ITKToVTKImageFilter to pass the images from ITK
to VTK</p>
<p><span>3.<span style="font: 7pt "Times New Roman";">
</span></span>Visualize the images by VTK</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I got the images visualized successfully. However, compared
with the visualization result of using VTK reader directly, the images are inverse
vertically, and the same is the order of the slices.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Attached please find the image. Could anyone tell me how to
solve the problem?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks!</p>
