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->SetNumberOfWorkUnits(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.

void itk::DiffusionTensor3DReconstructionImageFilter< TReferenceImagePixelType, TGradientImagePixelType, TTensorPixelType, TMaskImageType >::DynamicThreadedGenerateData ( const OutputImageRegionType &  outputRegionForThread)
overrideprotectedvirtual

If an imaging filter can be implemented as a multithreaded algorithm, the filter will provide an implementation of ThreadedGenerateData() or DynamicThreadedGenerateData(). This superclass will automatically split the output image into a number of pieces, spawn multiple threads, and call (Dynamic)ThreadedGenerateData() in each thread. Prior to spawning threads, the BeforeThreadedGenerateData() method is called. After all the threads have completed, the AfterThreadedGenerateData() method is called. If an image processing filter cannot support threading, that filter should provide an implementation of the GenerateData() method instead of providing an implementation of (Dynamic)ThreadedGenerateData(). If a filter provides a GenerateData() method as its implementation, then the filter is responsible for allocating the output data. If a filter provides a (Dynamic)ThreadedGenerateData() method as its implementation, then the output memory will allocated automatically by this superclass. The (Dynamic)ThreadedGenerateData() method should only produce the output specified by "outputThreadRegion" parameter. (Dynamic)ThreadedGenerateData() cannot write to any other portion of the output image (as this is responsibility of a different thread).

DynamicThreadedGenerateData() is the newer variant without threadId, and is the preferred signature, which is called by default. This variant can split the requested region into different number of pieces depending on current multi-processing load, which allows better load balancing. The non-dynamic (also known as classic) ThreadedGenerateData() signature has threadId, and number of pieces to be split into is known in advance. It is activated by calling this->DynamicMultiThreadingOff(); in derived class constructor. It should be used when the multi-threaded algorithm needs to pre-allocate some data structure with size dependent on the number of pieces (also known as chunks, work units, and sometimes also incorrectly as threads). Only PlatformMultiThreader guarantees that each piece will be processed in its own specific thread. Pool and TBB multi-threaders maintain a pool of threads (normally equal to number of processing cores) which they use to process the pieces. This normally results in a single thread being reused to process multiple work units.
