[vtkusers] 3D Volume from 2D parallel slices

[Frederic DANESI]

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)
un peu rapide pour ce soir, mais dispo dans la semaine si le problème
persiste

> 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.

> http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/PolyDataToImageData 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.
