[Insight-users] Itk Segmentation Fault

[Magnotta, Vincent A]

We have an application hosted on NITRC that implements registration of two datasets using ITK diffeomorphic demons. You would need to convert the images to Nifti or another suitable format first, but it should work for your application.

What ITK version are running ?

Another things is that "DeformationPixelType" need to be a float or double.

Please post the source code.

Hello!

Thank you for your reply.
I've done it as you said, changed the data types, but unfortunately it gives out a full screen of error now. I am trying to read two dicom series from two different directories, and perform Demons registration, then save the output as a new dicom file. Maybe this is different from what you are doing, and that is why your data type does not work for my code I think.

Do you have any other good suggestions?

Best Regards,

Hi, Im recently used this class  and I had no errors.  This is my code:

  typedef itk::Image<PixelType,3> ImageType;
typedef itk::Image< itk::Vector<DeformationPixelType, 3>, 3> DeformationFieldType;
typedef itk::DiffeomorphicDemonsRegistrationFilter <ImageType, ImageType, DeformationFieldType> FilterType;

typename FilterType::Pointer filter = FilterType::New();


filter->SetFixedImage(img_diastole->GetOutput());
filter->SetMovingImage(img_sistole->GetOutput());
filter->Update();

typename DeformationFieldType::Pointer deformacion = filter->GetDeformationField();

Hello all!

I am using Demons algorithm to perform registration of two DICOM series. My code compiles without any error. And when I run it, at the final step, when it updates the filter, there is a "0" on the screen, and gives error message saying "Segmentation Fault".

What should I do for it?

Thank you in advance!
