[vtkusers] creating mesh - error

[InfoSeekerr]

I tried the code presented in the following link
http://www.vtk.org/pipermail/vtkusers/2009-January/098886.html , but I got
the imagedata by reading dicom series of CT it give error wich is :
vtktypeID can't load 17280129 element of size..........
Any advice please 

my code is:
			// Read a DICOM series path:
			vtk::vtkDICOMImageReader ^VDR = gcnew vtk::vtkDICOMImageReader();
			VDR->SetDirectoryName("H:\\work\\Master
Degree\\DataSet\\case1-\\DICOM\\PA1\\ST1\\SE1");
			VDR->SetDataOrigin(0, 0, 0);

			VDR->Update();

			/////
			vtk::vtkImageChangeInformation ^VIC = gcnew
vtk::vtkImageChangeInformation();
			VIC->SetInput(VDR->GetOutput());

			VIC->CenterImageOn();

			VIC->Update();

			// set the imagedata 
			vtk::vtkImageData ^VoxelData = VIC->GetOutput();

			vtk::vtkMarchingCubes ^mcubes = gcnew vtk::vtkMarchingCubes();
			mcubes->GetOutput()->ReleaseDataFlagOff();
			mcubes->SetInput(VoxelData);
			mcubes->SetValue(0, 4);
			mcubes->ComputeGradientsOn();
			mcubes->Update();


			vtk::vtkSmoothPolyDataFilter ^smoother = gcnew
vtk::vtkSmoothPolyDataFilter();
			smoother->GetOutput()->ReleaseDataFlagOff();
			smoother->SetInput(mcubes->GetOutput());
			smoother->SetNumberOfIterations(5);
			smoother->SetRelaxationFactor(0.70);
			smoother->SetFeatureAngle(70);
			smoother->FeatureEdgeSmoothingOn();
			smoother->BoundarySmoothingOn();
			smoother->Update();

			vtk::vtkPolyDataNormals ^normals = gcnew vtk::vtkPolyDataNormals();
			normals->GetOutput()->ReleaseDataFlagOff();
			normals->SetInput(smoother->GetOutput());
			normals->SetFeatureAngle(80);
			normals->Update();

			vtk::vtkStripper ^stripper = gcnew vtk::vtkStripper();
			stripper->SetInput(normals->GetOutput());
			stripper->GetOutput()->ReleaseDataFlagOff();
			stripper->Update();



			vtkPolyDataMapper ^mapper = gcnew vtkPolyDataMapper();
			mapper->SetInput(stripper->GetOutput());

			/////////////////////


			// actor coordinates geometry, properties, transformation 
			vtkActor ^aSphere = gcnew vtkActor();
			aSphere->SetMapper(mapper);
			//aSphere.GetProperty().SetColor(0,0,1); // sphere color blue

			// a renderer and render window 
			vtkRenderer ^ren1 = gcnew vtkRenderer();
			vtkRenderWindow ^renWin = gcnew vtkRenderWindow();
			renWin->AddRenderer(ren1);

			// an interactor 
			vtkRenderWindowInteractor ^iren = gcnew vtkRenderWindowInteractor();
			iren->SetRenderWindow(renWin);

			// add the actor to the scene 
			ren1->AddActor(aSphere);
			//ren1.SetBackground(1,1,1); // Background color white

			// render an image (lights and cameras are created automatically) 
			renWin->Render();

			// begin mouse interaction 
			iren->Start();
