[vtkusers] 2D photographs to 3D model.

[michiel mentink]

here's a bit of example code you can use.
It opens dicom images and saves it to metaImage.

greets, Michael


OpenDicomSaveMetaImage Open dicom images and convert to metaImage: a
filetype that is supported by both ITK and VTK

usage:  ./DICOMSeries /path/to/your/dicomimages outputFileName.hdr

*DICOMSeries.cxx*

#include <vtkCellArray.h>
#include <vtkCellData.h>
#include <vtkPolyData.h>
#include <vtkImageData.h>
#include <vtkSmartPointer.h>
#include <vtkDICOMImageReader.h>
#include <vtkXMLImageDataWriter.h>
#include <vtkMetaImageWriter.h>

int main(int argc, char *argv[])
{
  if(argc != 3)
    {
    vtkstd::cout << "Required arguments: Folder containing .dcm files and
also name of OutputFile" << vtkstd::endl;
    }
  vtkstd::string folder = argv[1];
  vtkstd::string outputFile = argv[2];

  // Read all the DICOM files in the specified directory.
  vtkSmartPointer<
vtkDICOMImageReader> reader = vtkSmartPointer<vtkDICOMImageReader>::New();
  reader->SetDirectoryName(folder.c_str());
  reader->Update();

  vtkImageData* imagedata = reader->GetOutput();
  vtkSmartPointer<vtkMetaImageWriter> metaImageWriter =
vtkSmartPointer<vtkMetaImageWriter>::New();
  metaImageWriter->SetInput(imagedata);
  metaImageWriter->SetFileName(outputFile.c_str());
  metaImageWriter->Update();

  return 0;
