[vtkusers] how to check for error when using vtkDICOMImageReader?

[Mark Wyszomierski]

Hi,

How do you check if an error occured when reading DICOM images using
vtkDICOMImageReader? I'm just doing the following:

    vtkDICOMImageReader* pRead = vtkDICOMImageReader::New();
    pRead->SetDirectoryName(strPath.c_str());
    pRead->Update();

Thanks,
Mark
