Detailed Description

template<typename TReferenceImagePixelType, typename TGradientImagePixelType = TReferenceImagePixelType, typename TTensorPixelType = double, typename TMaskImageType = Image<unsigned char, 3>>
class itk::DiffusionTensor3DReconstructionImageFilter< TReferenceImagePixelType, TGradientImagePixelType, TTensorPixelType, TMaskImageType >

This class takes as input one or more reference image (acquired in the absence of diffusion sensitizing gradients) and 'n' diffusion weighted images and their gradient directions and computes an image of tensors. (with DiffusionTensor3D as the pixel type). Once that is done, you can apply filters on this tensor image to compute FA, ADC, RGB weighted maps etc.

Inputs and Usage
There are two ways to use this class. When you have one reference image and n gradient images, you would use the class as
* filter->SetReferenceImage( image0 );
* filter->AddGradientImage( direction1, image1 );
* filter->AddGradientImage( direction2, image2 );
* ...
*
When you have the 'n' gradient and one or more reference images in a single multi-component image (VectorImage), you can specify the images simply as
* filter->SetGradientImage( directionsContainer, vectorImage );
*
Note that this method is used to specify both the reference and gradient images. This is convenient when the DWI images are read in using the NRRD format. Like the Nrrd format, the reference images are those components of the vectorImage whose gradient direction is (0,0,0). If more than one reference image is present, they are averaged prior to applying the Stejskal-Tanner equations.
Outputs
The output image is an image of Tensors:
* Image< DiffusionTensor3D< TTensorPixelType >, 3 >
*
Parameters
  • Threshold - Threshold on the reference image data. The output tensor will be a null tensor for pixels in the reference image that have a value less than this.
  • BValue - See the documentation of SetBValue().
  • At least 6 gradient images must be specified for the filter to be able to run.
Template parameters
The class is templated over the pixel type of the reference and gradient images (expected to be scalar data types) and the internal representation of the DiffusionTensor3D pixel (double, float etc).

Warning
Although this filter has been written to support multiple threads, please set the number of threads to 1.
* filter->SetNumberOfThreads(1);
*
This is due to buggy code in netlib/dsvdc, that is called by vnl_svd. (used to compute the pseudo-inverse to find the dual tensor basis).

overrideprotectedvirtual

If an imaging filter needs to perform processing after the buffer has been allocated but before threads are spawned, the filter can can provide an implementation for BeforeThreadedGenerateData(). The execution flow in the default GenerateData() method will be: 1) Allocate the output buffer 2) Call BeforeThreadedGenerateData() 3) Spawn threads, calling ThreadedGenerateData() in each thread. 4) Call AfterThreadedGenerateData() Note that this flow of control is only available if a filter provides a ThreadedGenerateData() method and NOT a GenerateData() method.

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Another set method to add a gradient directions and its corresponding image. The image here is a VectorImage. The user is expected to pass the gradient directions in a container. The ith element of the container corresponds to the gradient direction of the ith component image the VectorImage. For the baseline image, a vector of all zeros should be set.
