Ok, I have no longer the MetaImage error, but now it crashes on the line view->SetImage(ImageOriginale[0]);
Any ideas?

Paul

This line just create an array of 10 pointers:
vtkImageData** ImageOriginale = new vtkImageData*[10];
It means that ImageOriginale[0] to ImageOriginale[9] are not initialized.
therefore the following line is crashing:
ImageOriginale[0]->DeepCopy(caster->GetOutput()) ;
you should have this piece of code first:
int i=0;
while(i<10)
{
ImageOriginale[i]=vtkImageData::New();
++i;
}
