Je ne suis pas familier de GDCM2, mais les images d'origine ont toutes la même taille et la même position exceptée dans une dimension ? si c'est le cas, le plus simple plutot que de construire un contour par image est de construire un contour 3D directement ... (cf exemples VTK headsq)<div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Hi all,<br>
<br>
I am writing mathematical models for cancer growth. The computations are based on cartesian grids, so I am dealing with 3D structured grids. The data I am trying to use comes from DICOM RT structs. After reading them with GDCM2, I have a vtkPolyData containing 2D contours on parallel slices (as shown in the attached pictures). I am trying to reconstruct the full 3D volume of the tumor as a binary mask defined on a cartesian grid.<br>
<br>
The following example <a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/PolyDataToImageData" target="_blank">http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/PolyDataToImageData</a> to construct a volume from the contours does not work in my case (the contour is not closed). Is there a way to construct the volume using VTK, or should I look for more specialized toolkits.<br>
<br>
Thanks a lot !<br><font color="#888888">
