The output of the fiber tracking is vtkPolyData (i.e. Polylines) that can be loaded into Slicer3 for visualization. The poly data can be saved in either old VTK format files (.vtk) or in the new VTK XML format (.xml). The polylines contain point data that defines ther Tensor at each point along the fiber tract. This can then be used to rendered as glyphs in Slicer3 and can be used to define severeal scalar measures without referencing back to the anisotropy images. (1) Free tracking is a basic streamlines algorithm. This is a direct implementation of the method original proposed by Basser et al. The tracking follows the primarty eigenvector. The tracking begins with seed points in the starting region. Only those voxels above the specified anisotropy threshold in the starting region are used as seed points. Tracking terminates either as a result of maximum fiber length, low ansiotropy, or large curvature. This is a great way to explore your data. (2) The streamlines algorithm is a direct implementation of the method originally proposed by Basser et al. The tracking follows the primary eigenvector. The tracking begins with seed points in the starting region. Only those voxels above the specified anisotropy threshold in the starting region are used as seed points. Tracking terminates either by reaching the ending region or reaching some stopping criteria. Stopping criteria are specified using the following parameters: tracking threshold, curvature threshold, and max length. Only paths terminating in the ending region are kept in this method. The TEND algorithm proposed by Lazar et al. (Human Brain Mapping 18:306-321, 2003) has been instrumented. This can be enabled using the --useTend option while performing Streamlines tracking. This utilizes the entire diffusion tensor to deflect the incoming vector instead of simply following the primary eigenvector. The TEND parameters are set using the --tendF and --tendG options. (3) Graph Search tracking is the first step in the full GTRACT algorithm developed by Cheng et al. (NeuroImage 31(3): 1075-1085, 2006) for finding the tracks in a tensor image. This method was developed to generate fibers in a Tensor representation where crossing fibers occur. The graph search algorithm follows the primary eigenvector in non-ambigous regions and utilizes branching and a graph search algorithm in ambigous regions. Ambiguous tracking regions are defined based on two criteria: Branching Al Threshold (anisotropy values below this value and above the traching threshold) and Curvature Major Eigen (angles of the primary eigenvector direction and the current tracking direction). In regions that meet this criteria, two or three tracking paths are considered. The first is the standard primary eigenvector direction. The second is the seconadary eigenvector direction. This is based on the assumption that these regions may be prolate regions. If the Random Walk option is selected then a third direction is also considered. This direction is defined by a cone pointing from the current position to the centroid of the ending region. The interior angle of the cone is specified by the user with the Branch/Guide Angle parameter. A vector contained inside of the cone is selected at random and used as the third direction. This method can also utilize the TEND option where the primary tracking direction is that specified by the TEND method instead of the primary eigenvector. The parameter '--maximumBranchPoints' allows the tracking to have this number of branches being considered at a time. If this number of branch points is exceeded at any time, then the algorithm will revert back to a streamline alogrithm until the number of branches is reduced. This allows the user to constrain the computational complexity of the algorithm. (4) The second phase of the GTRACT algorithm is Guided Tracking. This method incorporates anatomical information about the track orientation using an initial guess of the fiber track. In the originally proposed GTRACT method, this would be created from the fibers resulting from the Graph Search tracking. However, in practice this can be created using any method and could be defined manually. To create the guide fiber the program gtractCreateGuideFiber can be used. This program will load a fiber tract that has been generated and create a centerline representation of the fiber tract (i.e. a single fiber). In this method, the fiber tracking follows the primary eigenvector direction unless it deviates from the guide fiber track by a angle greater than that specified by the '--guidedCurvatureThreshold' parameter. The user must specify the guide fiber when running this program. version: 4.0.0 documentation-url: http://wiki.slicer.org/slicerWiki/index.php/Modules:GTRACT license: http://mri.radiology.uiowa.edu/copyright/GTRACT-Copyright.txt contributor: This tool was developed by Vincent Magnotta, Greg Harris and Yongqiang Zhao. acknowledgements: Funding for this version of the GTRACT program was provided by NIH/NINDS R01NS050568-01A2S1 """ input_spec = gtractFiberTrackingInputSpec output_spec = gtractFiberTrackingOutputSpec _cmd = " gtractFiberTracking " _outputs_filenames = {"outputTract": "outputTract.vtk"} _redirect_x = False class extractNrrdVectorIndexInputSpec(CommandLineInputSpec): inputVolume = File( desc="Required: input file containing the vector that will be extracted", exists=True, argstr="--inputVolume %s", ) vectorIndex = traits.Int( desc="Index in the vector image to extract", argstr="--vectorIndex %d" ) setImageOrientation = traits.Enum( "AsAcquired", "Axial", "Coronal", "Sagittal", desc="Sets the image orientation of the extracted vector (Axial, Coronal, Sagittal)", argstr="--setImageOrientation %s", ) outputVolume = traits.Either( traits.Bool, File(), hash_files=False, desc="Required: name of output NRRD file containing the vector image at the given index", argstr="--outputVolume %s", ) numberOfThreads = traits.Int( desc="Explicitly specify the maximum number of threads to use.", argstr="--numberOfThreads %d", ) class extractNrrdVectorIndexOutputSpec(TraitedSpec): outputVolume = File( desc="Required: name of output NRRD file containing the vector image at the given index", exists=True, ) class extractNrrdVectorIndex(SEMLikeCommandLine): """title: Extract Nrrd Index category: Diffusion.GTRACT description: This program will extract a 3D image (single vector) from a vector 3D image at a given vector index. version: 4.0.0 documentation-url: http://wiki.slicer.org/slicerWiki/index.php/Modules:GTRACT license: http://mri.radiology.uiowa.edu/copyright/GTRACT-Copyright.txt contributor: This tool was developed by Vincent Magnotta and Greg Harris. acknowledgements: Funding for this version of the GTRACT program was provided by NIH/NINDS R01NS050568-01A2S1 """ input_spec = extractNrrdVectorIndexInputSpec output_spec = extractNrrdVectorIndexOutputSpec _cmd = " extractNrrdVectorIndex " _outputs_filenames = {"outputVolume": "outputVolume.nii"} _redirect_x = False class gtractResampleFibersInputSpec(CommandLineInputSpec): inputForwardDeformationFieldVolume = File( desc="Required: input forward deformation field image file name", exists=True, argstr="--inputForwardDeformationFieldVolume %s", ) inputReverseDeformationFieldVolume = File( desc="Required: input reverse deformation field image file name", exists=True, argstr="--inputReverseDeformationFieldVolume %s", ) inputTract = File( desc="Required: name of input vtkPolydata file containing tract lines.", exists=True, argstr="--inputTract %s", ) outputTract = traits.Either( traits.Bool, File(), hash_files=False, desc="Required: name of output vtkPolydata file containing tract lines and the point data collected along them.", argstr="--outputTract %s", ) writeXMLPolyDataFile = traits.Bool( desc="Flag to make use of the XML format for vtkPolyData fiber tracts.", argstr="--writeXMLPolyDataFile ", ) numberOfThreads = traits.Int( desc="Explicitly specify the maximum number of threads to use.", argstr="--numberOfThreads %d", ) class gtractResampleFibersOutputSpec(TraitedSpec): outputTract = File( desc="Required: name of output vtkPolydata file containing tract lines and the point data collected along them.", exists=True, ) class gtractResampleFibers(SEMLikeCommandLine): """title: Resample Fibers category: Diffusion.GTRACT description: This program will resample a fiber tract with respect to a pair of deformation fields that represent the forward and reverse deformation fields. version: 4.0.0 documentation-url: http://wiki.slicer.org/slicerWiki/index.php/Modules:GTRACT license: http://mri.radiology.uiowa.edu/copyright/GTRACT-Copyright.txt contributor: This tool was developed by Vincent Magnotta and Greg Harris. acknowledgements: Funding for this version of the GTRACT program was provided by NIH/NINDS R01NS050568-01A2S1 """ input_spec = gtractResampleFibersInputSpec output_spec = gtractResampleFibersOutputSpec _cmd = " gtractResampleFibers " _outputs_filenames = {"outputTract": "outputTract.vtk"} _redirect_x = False class gtractTensorInputSpec(CommandLineInputSpec): inputVolume = File( desc="Required: input image 4D NRRD image.

This step takes the diffusion tensor image data and generates a tensor representation of the data based on the signal intensity decay, b values applied, and the diffusion difrections. The apparent diffusion coefficient for a given orientation is computed on a pixel-by-pixel basis by fitting the image data (voxel intensities) to the Stejskal-Tanner equation. If at least 6 diffusion directions are used, then the diffusion tensor can be computed. This program uses itk::DiffusionTensor3DReconstructionImageFilter. The user can adjust background threshold, median filter, and isotropic resampling. version: 4.0.0 documentation-url: http://wiki.slicer.org/slicerWiki/index.php/Modules:GTRACT license: http://mri.radiology.uiowa.edu/copyright/GTRACT-Copyright.txt contributor: This tool was developed by Vincent Magnotta and Greg Harris. acknowledgements: Funding for this version of the GTRACT program was provided by NIH/NINDS R01NS050568-01A2S1 """ input_spec = gtractTensorInputSpec output_spec = gtractTensorOutputSpec _cmd = " gtractTensor " _outputs_filenames = {"outputVolume": "outputVolume.nrrd"} _redirect_x = False
