2.全域變數

using namespace std;
typedef short PixelType;
const unsigned int   Dimension = 2;
typedef itk::Image< PixelType, Dimension > Input2dImageType;
typedef itk::Image< PixelType, 3 > Input3dImageType;

typedef itk::Image< PixelType, Dimension > Output2dImageType;
typedef itk::Image< PixelType, 3 > Output3dImageType;

typedef itk::GDCMImageIO   ImageIOType;//GDCMImageIO讀DICOM
ImageIOType::Pointer gdcmImageIO = ImageIOType::New();

using ReaderType3d = itk::ImageSeriesReader< Input3dImageType >;
ReaderType3d::Pointer reader3d = ReaderType3d::New();

typedef itk::ImageFileReader< Input2dImageType > ReaderType2d;
ReaderType2d::Pointer reader2d = ReaderType2d::New();

using NamesGeneratorType = itk::GDCMSeriesFileNames;
NamesGeneratorType::Pointer nameGenerator = NamesGeneratorType::New();

3.讀取dicom序列圖

Input3dImageType::Pointer read3dImage(const char *path)
{
	reader3d->SetImageIO(gdcmImageIO);
	nameGenerator->SetUseSeriesDetails(true);
	nameGenerator->AddSeriesRestriction("0008|0021");
	nameGenerator->SetDirectory(path);

	using SeriesIdContainer = std::vector< std::string >;
	const SeriesIdContainer & seriesUID = nameGenerator->GetSeriesUIDs();
	auto seriesItr = seriesUID.begin();
	auto seriesEnd = seriesUID.end();

	using FileNamesContainer = std::vector< std::string >;
	FileNamesContainer fileNames;
	std::string seriesIdentifier;
	while (seriesItr != seriesEnd)
	{
		seriesIdentifier = seriesItr->c_str();
		fileNames = nameGenerator->GetFileNames(seriesIdentifier);
		++seriesItr;
	}
	reader3d->SetFileNames(fileNames);
	reader3d->Update();
	return reader3d->GetOutput();
}

4.itk影像轉vtk影像

vtkSmartPointer<vtkImageData> itkToVtk(Input3dImageType::Pointer image)
{
	typedef itk::ImageToVTKImageFilter< Input3dImageType> itkTovtkFilterType;
	itkTovtkFilterType::Pointer itkTovtkImageFilter = itkTovtkFilterType::New();
	itkTovtkImageFilter->SetInput(image);//設定影像資料從ITK轉向VTK
	itkTovtkImageFilter->Update();

	vtkSmartPointer< vtkImageFlip > flip1 = vtkSmartPointer< vtkImageFlip >::New();
	flip1->SetInputData(itkTovtkImageFilter->GetOutput());

	flip1->SetFilteredAxes(1);
	flip1->Update();
	return flip1->GetOutput();
}

5.vtk顯示與互動

class vtkSliderCallback : public vtkCommand
{
public:
	static vtkSliderCallback *New()
	{
		return new vtkSliderCallback;
	}
	virtual void Execute(vtkObject *caller, unsigned long, void*)
	{
		vtkSliderWidget *sliderWidget =
			reinterpret_cast<vtkSliderWidget*>(caller);
		this->viewer->SetSlice(static_cast<vtkSliderRepresentation *>(sliderWidget->GetRepresentation())->GetValue());
	}
	vtkSliderCallback() {}
	vtkSmartPointer<vtkImageViewer2> viewer = nullptr;
};

void show3dImage(Input3dImageType::Pointer image)
{
	vtkSmartPointer<vtkImageViewer2> viewer =
		vtkSmartPointer<vtkImageViewer2>::New();
	viewer->SetInputData(itkToVtk(image));
	//設定基本屬性
	viewer->SetSize(640, 480);
	viewer->SetColorLevel(500);
	viewer->SetColorWindow(2000);
	viewer->SetSlice(40);
	viewer->SetSliceOrientationToXY();
	viewer->Render();
	viewer->GetRenderer()->SetBackground(0, 0, 0);
	viewer->GetRenderWindow()->SetWindowName("ImageViewer2D");

	vtkSmartPointer<vtkInteractorStyleTrackballCamera> style =
		vtkSmartPointer<vtkInteractorStyleTrackballCamera>::New();
	vtkSmartPointer<vtkRenderWindowInteractor> rwi =
		vtkSmartPointer<vtkRenderWindowInteractor>::New();
	//設定互動屬性
	viewer->SetupInteractor(rwi);
	//viewer->GetRenderer()->GetRenderWindow()->GetInteractor()->SetInteractorStyle(style);
	
	vtkSmartPointer<vtkSliderRepresentation2D> sliderRep =
		vtkSmartPointer<vtkSliderRepresentation2D>::New();
	sliderRep->SetMinimumValue(viewer->GetSliceMin());
	sliderRep->SetMaximumValue(viewer->GetSliceMax());
	sliderRep->SetValue(5.0);
	sliderRep->GetSliderProperty()->SetColor(1, 0, 0);//red
	sliderRep->GetTitleProperty()->SetColor(1, 0, 0);//red
	sliderRep->GetLabelProperty()->SetColor(1, 0, 0);//red
	sliderRep->GetSelectedProperty()->SetColor(0, 1, 0);//green
	sliderRep->GetTubeProperty()->SetColor(1, 1, 0);//yellow
	sliderRep->GetCapProperty()->SetColor(1, 1, 0);//yellow
	sliderRep->GetPoint1Coordinate()->SetCoordinateSystemToDisplay();
	sliderRep->GetPoint1Coordinate()->SetValue(40, 40);
	sliderRep->GetPoint2Coordinate()->SetCoordinateSystemToDisplay();
	sliderRep->GetPoint2Coordinate()->SetValue(500, 40);
	vtkSmartPointer<vtkSliderWidget> sliderWidget =
		vtkSmartPointer<vtkSliderWidget>::New();
	sliderWidget->SetInteractor(rwi);
	sliderWidget->SetRepresentation(sliderRep);
	sliderWidget->SetAnimationModeToAnimate();
	sliderWidget->EnabledOn();

	vtkSmartPointer<vtkSliderCallback> callback =
		vtkSmartPointer<vtkSliderCallback>::New();
	callback->viewer = viewer;

	sliderWidget->AddObserver(vtkCommand::InteractionEvent, callback);
	vtkSmartPointer<vtkAxesActor> axes = vtkSmartPointer<vtkAxesActor>::New();
	double axesSize[3] = { 100,100,100 };
	axes->SetTotalLength(axesSize);
	axes->SetConeRadius(0.1);
	axes->SetShaftTypeToLine();
	axes->SetAxisLabels(false);
	viewer->GetRenderer()->AddActor(axes);
	rwi->Start();
	viewer->Render();
}

6.匯出dicom序列圖

void write3dImage(const char *path, Input3dImageType::Pointer image)
{
	itksys::SystemTools::MakeDirectory(path);
	typedef itk::ImageSeriesWriter < Input3dImageType, Output2dImageType >	WriterType;
	WriterType::Pointer writer = WriterType::New();

	nameGenerator->SetOutputDirectory(path);
	writer->SetMetaDataDictionaryArray(reader3d->GetMetaDataDictionaryArray());
	writer->SetImageIO(gdcmImageIO);
	writer->SetFileNames(nameGenerator->GetOutputFileNames());
	writer->SetInput(image);
	writer->Update();
}

7.主函式

int main()
{
	const char *Input_Name = ("C:\\Users\\lDesktop\\test1\\in");
	const char *output_Name = ("C:\\Users\\lDesktop\\test1\\out");
	Input3dImageType::Pointer image = read3dImage(Input_Name);
	show3dImage(image);
	//匯出dicom序列圖
	//write3dImage(output_Name ,image);
	return EXIT_SUCCESS;
}
