以下是使用 ITK 和 VTK 显示 DICOM 图像的示例代码,代码中使用了 vtkDICOMImageReader 和 itk::GDCMImageIO 读取 DICOM 文件,并使用 vtkImageViewer2 显示 DICOM 图像:
使用 ITK 显示 DICOM 图像的示例代码:
```cpp
#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkGDCMImageIO.h"
#include "itkImageToVTKImageFilter.h"
#include "vtkSmartPointer.h"
#include "vtkImageViewer2.h"
int main(int argc, char* argv[])
{
// 读取 DICOM 文件
typedef itk::Image<unsigned short, 3> ImageType;
typedef itk::ImageFileReader<ImageType> ReaderType;
typedef itk::GDCMImageIO ImageIOType;
ReaderType::Pointer reader = ReaderType::New();
ImageIOType::Pointer dicomIO = ImageIOType::New();
reader->SetFileName("DICOMFile.dcm");
reader->SetImageIO(dicomIO);
reader->Update();
// 将 itk::Image 转换为 vtkImageData,并显示
typedef itk::ImageToVTKImageFilter<ImageType> ConnectorType;
ConnectorType::Pointer connector = ConnectorType::New();
connector->SetInput(reader->GetOutput());
connector->Update();
vtkSmartPointer<vtkImageData> imageData = connector->GetOutput();
vtkSmartPointer<vtkImageViewer2> viewer = vtkSmartPointer<vtkImageViewer2>::New();
viewer->SetInputData(imageData);
viewer->Render();
viewer->GetRenderWindow()->SetWindowName("DICOM Viewer");
viewer->GetRenderWindow()->Render();
viewer->Interact();
return EXIT_SUCCESS;
}
```
使用 VTK 显示 DICOM 图像的示例代码:
```cpp
#include "vtkDICOMImageReader.h"
#include "vtkSmartPointer.h"
#include "vtkImageViewer2.h"
int main(int argc, char* argv[])
{
// 读取 DICOM 文件
vtkSmartPointer<vtkDICOMImageReader> reader = vtkSmartPointer<vtkDICOMImageReader>::New();
reader->SetFileName("DICOMFile.dcm");
reader->Update();
// 显示 DICOM 图像
vtkSmartPointer<vtkImageViewer2> viewer = vtkSmartPointer<vtkImageViewer2>::New();
viewer->SetInputData(reader->GetOutput());
viewer->Render();
viewer->GetRenderWindow()->SetWindowName("DICOM Viewer");
viewer->GetRenderWindow()->Render();
viewer->Interact();
return EXIT_SUCCESS;
}
```
以上代码仅供参考,具体实现可能需要根据实际情况进行调整。
