Detailed Description

template<class TInputImage, class TOutputImage = TInputImage>
class rtk::BoellaardScatterCorrectionImageFilter< TInputImage, TOutputImage >

Scatter correction for cone-beam CT reconstruction.

The scatter correction algorithm is based on the work of [Boellaard, Rad Onc, 1997]. It assumes a homogeneous contribution of scatter which is computed depending on the amount of tissues traversed by x-rays.
