[vtkusers] display DICOM image

[Massi]

Hi
I'm trying to read a series of DICOM images (60 images) from file and
display them in a Qt GUI using QVTKWidget. I wrote a simple code:

    vtkSmartPointer<vtkDICOMImageReader> reader =
vtkSmartPointer<vtkDICOMImageReader>::New();
    reader->SetDirectoryName(DICOMImage);
    reader->Update();

    vtkImageMapper *imageMapper =vtkImageMapper::New();
    imageMapper->SetInput(reader->GetOutput());
    imageMapper->GetInput();
    vtkImageActor *mapActor= vtkImageActor::New();
    mapActor->SetInput(imageMapper->GetInput());
    vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
    renderer->AddActor(mapActor);
  
    widget.qvtkWidget->GetRenderWindow()->AddRenderer(renderer);
    widget.qvtkWidget->update();
    
    But I got 2 errors:
ERROR: In c:/Users/Massi/Downloads/VTK/IO/vtkDICOMImageReader.cxx, line 346
vtkDICOMImageReader (0x7a70b48): There was a problem retrieving data from:
C:/Users/Massi/Downloads/PNEUMATIX/Cardiovascular Heart-Cardiac
Function/fl3d-cor//IM-0001-0001.dcm

ERROR: In c:/Users/Massi/Downloads/VTK/Rendering/vtkImageActor.cxx, line 266
vtkOpenGLImageActor (0xd1ebb98): This filter requires unsigned char scalars
as input

how can I fix this problem?

thank you for your help!
