Detailed Description

template<class TInputPixel1, class TInputPixel2, class TInputPixel3, class TOutputpixel>
class mitk::ConvertToConcentrationViaT1CalcFunctor< TInputPixel1, TInputPixel2, TInputPixel3, TOutputpixel >

Ternary functor that converts MR signal to concentration via T1 mapping using the variable flip angle method.

This functor computes pre-contrast T1 (T10) from the baseline and proton-density weighted (PDW) images using variable flip angle ratios, then calculates the post-contrast T1 from the current signal, and finally derives the concentration:

C(t) = (1/T1 - 1/T10) / (relaxivity / 1000)

Template Parameters

TInputPixel1	Pixel type of the dynamic signal image.
TInputPixel2	Pixel type of the baseline image.
TInputPixel3	Pixel type of the PDW image.
TOutputpixel	Pixel type of the output concentration image.
