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

[转身转瞬]

Dear Jon,
     Thanks for your reply.
     I only specified pixel type in the this line(typedef itk::Image<unsigned char,2> ImageType;),and after receiving your reply, I changed it to unsigned short, short, and signed short which was not working unfortunately.
     Have any other thoughts about it?
                                                                                                                                    Guirong Liu

 Dear Guirong,   DICOM images most commonly use short pixel types.

 

 The error says that there is some problem with the pixel type you specified.

 

 HTH,

  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!

 (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"vtkSmartPointer.h"
#include"vtkImageFlip.h"
#include"vtkRenderer.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;

 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
