itk에서 dcm 또는 nii를 읽습니다.gz 데이터

핵심 코드는 다음과 같습니다. dcm이면nii로 변환됩니다.gz:

	#include "itkGDCMSeriesFileNames.h"

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

	using ImageIOTypeNII = itk::NiftiImageIO;
    using ReaderTypeNII = itk::ImageFileReader< Short3DImageType  >;
	using ReaderTypeDCM = itk::ImageSeriesReader;

     string sPatientFileDir = "";
	
	 sPatientFileDir = FolderNames.at(i) + pPatientFileName;

	 nameGenarator->SetInputDirectory(FolderNames.at(i));
	 nameGenarator->Update();
	 using FilenamesContainer = std::vector<:string>;
	 FilenamesContainer filenames = nameGenarator->GetInputFileNames();

	if ((_access(sPatientFileDir.data(), 0) != 0) && filenames.size()==0)//          nii.gz      dcm    0，      。
	{
		cout << sPatientFileDir << "not exist";
		continue;
	}
	bool bIsDcm = false;
	if (filenames.size() != 0)
	{
		bIsDcm = true;
	}
   

   Short3DImageType::Pointer OriImg;
	if (bIsDCM)
	{
		ReaderTypeDCM::Pointer Reader = ReaderTypeDCM::New();
		ImageIOTypeDCM::Pointer gNiftiImageIORead = ImageIOTypeDCM::New();
		Reader->SetImageIO(gNiftiImageIORead);

	}
	else
	{
