itk reading dicom series with multiframe and singleframe

Hi all,
I'm quite new to itk, but i'm loving this library. Now i got a problem. I
need to read a cardiac dicom series. It contains both multiframe and
singleframe dicom. If i use the normal code, i got an error telling me that
the sizes of multiframe dicoms are not regular. This is the code i use:
 const unsigned int InputDimension = 3;
  const unsigned int OutputDimension = 3;

  typedef signed short PixelType;

  typedef itk::Image< PixelType, InputDimension >
    InputImageType;
    typedef itk::Image< PixelType, 2 >
    InputImageType2;

  typedef itk::Image< PixelType, OutputDimension >
    OutputImageType;
  typedef itk::ImageSeriesReader< InputImageType >
    ReaderType;
  typedef itk::ImageFileReader< InputImageType2 >
    ReaderType2;

  typedef itk::GDCMImageIO
    ImageIOType;
  typedef itk::GDCMSeriesFileNames
    InputNamesGeneratorType;
