DTITubeSpatialObject and DTITubeSpatialObjectPoint

See Fiber format for a discussion of the DTITubeSpatialObject as a file format.

An itk::DTITubeSpatialObjectPoint represents DTI information at a physical coordinate. DTITubeSpatialObjectPoints are used to build itk::DTITubeSpatialObjects which can be connected into a tube network.

DTITubeSpatialObjectPoint stores the following information:

• Tensor.
  • Assumed to be a symmetric tensor of dimension 3.
  • 6 floating point values.
• Eigenvalues
  • 3 floating point values
• Eigenvectors
  • 3 vectors each with 3 floating point values
• FA
  • float
• GA
  • float
• ADC
  • float
• MRI.
  • 5 floating point values.
• Interpolation flag
  • int
• Number of dimensions
  • unsigned short
