#include <itkMRIBiasFieldCorrectionFilter.h>

Detailed Description

template<typename TInputImage, typename TOutputImage, typename TMaskImage>
class itk::MRIBiasFieldCorrectionFilter< TInputImage, TOutputImage, TMaskImage >

Corrects 3D MRI bias field.

This class is templated over the type of the input image (TInputImage) and the type of the output image (TOutputImage).

In MRI images, intensity inhomogeneities which are caused by magnetic settings, patients' position, and other factors are not unusual. The main purpose of this filter is to reduce such bias field. To estimate the bias field, we use Legendre polynomials. The 1+1 evolutionary optimizer searches for the best parameters of a Legendre polynomial (bias field estimate) which minimizes the total energy value of each image after bias field is eliminated. The default Legendre polynomial degree is 3.

The correction performs by default a multiplicative bias field correction by first log-transforming the input image. This log transform only works on images with grayscale values bigger than 0. The log-transform can be disabled and the filter computes an additive bias field.

There are three major processes in the whole bias correction scheme: slab identification, inter-slice intensity correction, and actual bias correction process. Users can turn on and off each process within the whole bias correction scheme using SetUsingSlabIdentification(bool, false by default), SetUsingInterSliceIntensityCorrection(bool, true by default), and SetUsingBiasFieldCorrection(bool, true by default) member function.

Only the last process (the actual bias field correction) is implemented in a multiresolution framework (without smoothing). Default is a standard level 2 multiresolution schedule (2 2 2 1 1 1).

The bias field correction method was initially developed and implemented by Martin Styner, Univ. of North Carolina at Chapel Hill, and his colleagues.

The multiresolution pyramid implementation is based on itkMultiResolutionPyramidImageFilter (without Gaussian smoothing)

◆ GenerateData()

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling DynamicThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter can be threaded, it should NOT provide a GenerateData() method but should provide a DynamicThreadedGenerateData() instead.

If the flag is true, inter-slice intensity correction and bias field correction will be performed slab by slab which is identified by the slab identifier (default value is false). NOTE: if users want to slab identification, all the input image data should be buffered.

◆ SetVolumeCorrectionMaximumIteration()

template<typename TInputImage , typename TOutputImage , typename TMaskImage >
virtual void itk::MRIBiasFieldCorrectionFilter< TInputImage, TOutputImage, TMaskImage >::SetVolumeCorrectionMaximumIteration ( int  _arg)
virtual

Set/Get the maximum iteration termination condition parameter for the bias field correction.

◆ UsingBiasFieldCorrectionOn()

template<typename TInputImage , typename TOutputImage , typename TMaskImage >
virtual void itk::MRIBiasFieldCorrectionFilter< TInputImage, TOutputImage, TMaskImage >::UsingBiasFieldCorrectionOn ( )
virtual

Set/Get the bias correction flag. If the flag is true, bias field correction runs. This flag sounds odd. But if users want to use only the inter-slice intensity correction without actual bias correction, disabling bias field correction would be an useful option (default value is true).

◆ UsingInterSliceIntensityCorrectionOn()

template<typename TInputImage , typename TOutputImage , typename TMaskImage >
virtual void itk::MRIBiasFieldCorrectionFilter< TInputImage, TOutputImage, TMaskImage >::UsingInterSliceIntensityCorrectionOn ( )
virtual

Set/Get the intensity correction flag. If the flag is true, inter-slice intensity correction will be applied before bias field correction (default value is true for 3D input images, and false for 2D input images).

◆ UsingSlabIdentificationOn()

template<typename TInputImage , typename TOutputImage , typename TMaskImage >
virtual void itk::MRIBiasFieldCorrectionFilter< TInputImage, TOutputImage, TMaskImage >::UsingSlabIdentificationOn ( )
virtual

Set/Get the slab correction flag. If the flag is true, inter-slice intensity correction and bias field correction will be performed slab by slab which is identified by the slab identifier (default value is false). NOTE: if users want to slab identification, all the input image data should be buffered.
