3 vtk读取并显示dicom文件

1 官方代码

2 测试代码

#include <vtkSmartPointer.h>
#include <vtkImageViewer2.h>
#include <vtkDICOMImageReader.h>
#include <vtkRenderWindow.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkRenderer.h>
#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL)
int main(int argc, char* argv[])
{
// Verify input arguments
//if (argc != 2)
//{
// std::cout << "Usage: " << argv[0]
// << " Filename(.img)" << std::endl;
// return EXIT_FAILURE;
//}

std::string inputFilename = "D:\\myproj\\vtk-proj\\代码13_ReadDICOMImages\\TestVtk\\TestVtk\\digest_article\\brain_001.dcm";

// Read all the DICOM files in the specified directory.
    vtkSmartPointer<vtkDICOMImageReader> reader =
        vtkSmartPointer<vtkDICOMImageReader>::New();
    reader->SetFileName(inputFilename.c_str());
    reader->Update();

// Visualize
    vtkSmartPointer<vtkImageViewer2> imageViewer =
        vtkSmartPointer<vtkImageViewer2>::New();
    imageViewer->SetInputConnection(reader->GetOutputPort());
    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
        vtkSmartPointer<vtkRenderWindowInteractor>::New();
    imageViewer->SetupInteractor(renderWindowInteractor);
    imageViewer->Render();
    imageViewer->GetRenderer()->ResetCamera();
    imageViewer->Render();

    renderWindowInteractor->Start();

return EXIT_SUCCESS;
}

需要下载一个.dcm文件

效果：
