Detailed Description

template<class TInputImagePixelType, class TOutputImagePixelType>
class itk::SplitDWImageFilter< TInputImagePixelType, TOutputImagePixelType >

Splits a DW-Image passed in as input into a 3D-t image where each volume coresponds to a gradient image ( or the unweighted b0 )

Several applications require to get the gradient images as a separate volume, f.e. the registration for head-motion correction. Also a reduction of the DW Image is possible when combined with its counterpart filter, the

mitkImageToDiffusionImageSource, which can reinterpret a 3d+t (scalar) image into a diffusion weighted image.

The dimension of the output does not match the dimension of the input hence we need to re-implement the CopyInformation method to avoid executing the default implementation which tries to copy the input information to the output

Returns the index list used for extraction.

The list is necessary for further processing, especially when a b-value threshold is used ( like in

void itk::SplitDWImageFilter< TInputImagePixelType, TOutputImagePixelType >::SetExtractAllAboveThreshold ( double  b_threshold,
BValueMapType  map 
)

Selects only the weighted images with b-value above the given b_threshold to be extracted.

Setting b_threshold to 0 will do the same as

SetExtractAll. Please note that some images have no true unweighted images as the minimal b-value is something like 5 so for extracting all.
Note
It will reorder the images!
Parameters
b_thresholdthe minimal b-value to be extracted
