AW: [Insight-users] Read series DICOM files by itkImageSeriesReader

[jiang]

Hi, Bill,
I try to use typedef itk::Image<unsigned short,3> ImageNDType; to replace
typedef itk::Image<unsigned short,5> ImageNDType;
But it still doesn't work.
My DICOM images are MR images. I can read it by example code
\ITK\InsightApplications-1.2.0\QtITK
Since the image file is 134KB big. I don't attach it here. I just copy the
message print out when I read it.

Thank you for your help. I'm looking forward to creating my first 3d image
by ITK!

Yes. That was just for testing purposes. Your real app will want to produce
a 3D volume. But that does not seem to be your problem. What is the source
of your DICOM images?

No. I don't want to define 5d data. It is copied from
\Insight\Testing\Code\IO\itkDICOMImageSeriesTest.cxx

You have declared the image to be 5 dimensional, not 3d. Is this what you
intended?

Hello all,
I want to build 3d image volume by a serie of DICOM files. So I write the
following code according to the example
\Insight\Testing\Code\IO\itkDICOMImageSeriesTest.cxx

#include "itkDICOMImageIO2Factory.h"
#include "itkDICOMImageIO2.h"
#include "itkImageSeriesReader.h"
#include "itkDICOMSeriesFileNames.h"
#include "../Testing/Code/BasicFilters/itkFilterWatcher.h"

int main(int argc, char **argv)
{

  typedef itk::Image<unsigned short,5> ImageNDType;
  typedef itk::ImageSeriesReader<ImageNDType> ReaderType;
  ReaderType::Pointer reader = ReaderType::New();

 itk::DICOMImageIO2::Pointer io = itk::DICOMImageIO2::New();

  // Get the DICOM filenames from the directory
  itk::DICOMSeriesFileNames::Pointer names =
itk::DICOMSeriesFileNames::New();
  names->SetDirectory(s);//s is the directory path

  reader->SetFileNames(names->GetFileNames());
  reader->SetImageIO(io);
  std::cout << names;

  try
    {
    if (atoi(argv[2]))
      {
      reader->ReverseOrderOn();
      }
    reader->Update();
    reader->GetOutput()->Print(std::cout);
    }
  catch (itk::ExceptionObject &ex)
    {
    std::cout << ex;
    return EXIT_FAILURE;
    }


	return EXIT_SUCCESS;
}


However this code can not work. I debug it and find that most codes are
correct. But the program stops at reader->Update();
What is the problem? How can I realize the series DICOM files reading?
I use the latest ITK tarball.



Thanks!
