[ITK] when using itkImageFileReader to read dicom image , it occurs assertion failure:pixeltype_debug==pixeltype.

[转身转瞬]

Hi,everyone,
      I'm using ITK to read CTA image(it's a kind of dicom image),and when it runs to the update ,the following error happens:
    in command line:Assertion failed:pixeltype_debug==pixeltype.  file..\..\..\..\..\InsightToolkit-4.4.0\Modules\IO\GDCM\src\itkGDCMImageIO.cxx,line 287
  
 in a window:
 Debug Error!
 Program:F:\..\..\..\helloworld7.exe
 R6010
 -abort() has been called
 (Press Retry to debug the application)
  
  
 My code is as follows:
 #include"itkImage.h"
#include"itkImageFileReader.h"
#include"itkImageToVTKImageFilter.h"
#include<itkGDCMImageIO.h>
#include"vtkImageViewer.h"
#include"vtkRenderWindowInteractor.h"
#include"vtkSmartPointer.h"
#include"vtkImageFlip.h"
#include"vtkRenderer.h"
#include"vtkImageActor.h"
#include"vtkCamera.h"
#include"vtkImageMapper.h"
 using namespace std;
 int main()
{
  typedef itk::Image<unsigned char,2> ImageType;
 typedef itk::ImageFileReader<ImageType> ReaderType;  
 ReaderType::Pointer reader=ReaderType::New();
  //获得DICOM文件读取对象
 typedef itk::GDCMImageIO ImageIOType;
 ImageIOType::Pointer gdcmImageIO=ImageIOType::New();
  //Filter of itk image data to vtk image data;
 typedef itk::ImageToVTKImageFilter<ImageType> FilterType;
 FilterType::Pointer connector=FilterType::New();
  //获得DICOM文件名并读取DICOM文件;
 char*DICOMName="F://c++projects//helloworld6//1.3.12.2.1107.5.1.4.60540.30000013102023122056200010862";
 reader->SetFileName(DICOMName);
 reader->SetImageIO(gdcmImageIO);
  cout<<"done0"<<endl;
 //ITK到VTK转化      
 connector->SetInput(reader->GetOutput());
 cout<<"done1"<<endl;
 connector->Update();//This is the place where error occurs!
 cout<<"done2"<<endl;
  vtkSmartPointer<vtkImageFlip>flip=vtkSmartPointer<vtkImageFlip>::New();
 //vtkSmartPointer<vtkImageMapper>
 flip->SetInput(connector->GetOutput());
 flip->SetFilteredAxis(1);
 //需要进行上下翻转才能正确显示;
 flip->Update();
 
 vtkSmartPointer<vtkImageActor>actor=vtkSmartPointer<vtkImageActor>::New();
 actor->SetInput(flip->GetOutput());
 actor->InterpolateOff();
  vtkSmartPointer<vtkRenderer>renderer=vtkSmartPointer<vtkRenderer>::New();
 renderer->AddActor(actor);
 
 vtkSmartPointer<vtkRenderWindow>renderWindow=vtkSmartPointer<vtkRenderWindow>::New();
 renderWindow->AddRenderer(renderer);
  vtkRenderWindowInteractor*iren=vtkRenderWindowInteractor::New();
  iren->SetRenderWindow(renderWindow);
 iren->Initialize();
 iren->Start();
  return 0;
}
 If anyone know how to fix this, could you please just help me?
 Thanks a lot.
                                                                                                                                         Guirong Liu
