This example reads a DICOM file and displays it on the screen. Here is an example data set.

ReadDICOM.cxx

#include <vtkSmartPointer.h>
#include <vtkImageViewer2.h>
#include <vtkDICOMImageReader.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkRenderer.h>
 
int main(int argc, char* argv[])
{
  // Verify input arguments
  if ( argc != 2 )
    {
    std::cout << "Usage: " << argv[0]
              << " Filename(.img)" << std::endl;
    return EXIT_FAILURE;
    }
 
  std::string inputFilename = argv[1];
 
  // Read all the DICOM files in the specified directory.
  vtkSmartPointer<vtkDICOMImageReader> reader =
    vtkSmartPointer<vtkDICOMImageReader>::New();
  reader->SetFileName(inputFilename.c_str());
  reader->Update();
 
  // Visualize
  vtkSmartPointer<vtkImageViewer2> imageViewer =
    vtkSmartPointer<vtkImageViewer2>::New();
  imageViewer->SetInputConnection(reader->GetOutputPort());
  vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
    vtkSmartPointer<vtkRenderWindowInteractor>::New();
  imageViewer->SetupInteractor(renderWindowInteractor);
  imageViewer->Render();
  imageViewer->GetRenderer()->ResetCamera();
  imageViewer->Render();
 
  renderWindowInteractor->Start();
 
  return EXIT_SUCCESS;
}
