Detailed Description

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

Binary functor that converts TurboFLASH MR signal values to contrast agent concentration.

Uses the TurboFLASH-specific formula to compute concentration:

C(t) = -1 / (Trec * alpha) * ln( S(t)/S0 - exp(Trec/T10) * (S(t)/S0 - 1) )

where Trec is the recovery time, alpha is the relaxivity, T10 is the pre-contrast T1 relaxation 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.

inline

Computes concentration from signal and baseline pixel values.

Returns 0 if the baseline is zero or if the logarithm argument is non-positive.

Parameters

[in]	value	The current signal intensity S(t).
[in]	baseline	The baseline signal intensity S0.

Returns

The computed contrast agent concentration.
