MITK Diffusion Image Replacement Guide
We have decided to remove the MITK::DiffusionImage and instead represent diffusion weighted images by mitk::Image pointing to an itk::VectorImage . This is mainly due to the fact, that there is no longer a reason to use separate classes and unifying the image reduces the maintenance cost.
What to replace
When adjusting your code to use the new data type you will have to replace the some calls, mitkDiffusionImagePointer is a MITK::DiffusionImage::Pointer, mitkImagePointer is the MITK::Image::Pointer containing the same data.
Old code
typedef mitk::DiffusionImage<DiffusionPixelType> DiffusionImageType; typedef DiffusionImageType::GradientDirectionContainerType GradientDirectionContainerType; // cast node DiffusionImageType* mitkDiffusionImagePointer= static_cast<DiffusionImageType*>(node->GetData()); // get gradient directions mitkDiffusionImagePointer->GetDirections(); // get reference b value mitkDiffusionImagePointer->GetReferenceBValue() // get the vector image data mitkDiffusionImagePointer->GetVectorImage()
New Code
typedef itk::VectorImage<DiffusionPixelType, dimension> ITKDiffusionImageType; typedef mitk::GradientDirectionsProperty::GradientDirectionsContainerType GradientDirectionContainerType; // cast node mitk::Image* mitkImagePointer = static_cast<mitk::Image*>(node->GetData()); // get gradient directions static_cast<mitk::GradientDirectionsProperty*>( mitkImagePointer->GetProperty("GradientDirections").GetPointer() )->GetGradientDirectionsContainer(); // get reference b value static_cast<mitk::FloatProperty*>(mitkImagePointer->GetProperty("ReferenceBValue").GetPointer() )->GetValue() // get the vector image data ITKDiffusionImageType::Pointer itkVectorImagePointer = ITKDiffusionImageType::New(); mitk::CastToItkVectorImage(mitkImagePointer, itkVectorImagePointer);
