Detailed Description

template<class TInputPixel1, class TInputPixel2, class TOutputpixel>
class mitk::ConvertT2ConcentrationFunctor< TInputPixel1, TInputPixel2, TOutputpixel >

Binary functor that converts T2-weighted MR signal values to contrast agent concentration.

Computes concentration from the logarithmic ratio of the signal to the baseline:

C(t) = -(k / TE) * ln(S(t) / S0)

where k is a proportionality factor, TE is the echo time, S(t) is the current signal, and S0 is the baseline signal.

Template Parameters

TInputPixel1	Pixel type of the dynamic signal image.
TInputPixel2	Pixel type of the baseline image.
TOutputpixel	Pixel type of the output concentration image.
