In the ConvertToConcentrationTurboFlashFunctor, the naming of the parameters is misleading:

m_Trec = relaxationtime;
m_alpha = relaxivity;
m_T10 = recoverytime;

It would be assumed that that Trec stands for the reconvery time, the relaxivity is r1 (alpha is usually used to denote the flip angle)and T1 is the relaxation time (T10 is usually the T1 relaxation time prior to contrast agent injection).
In this task, it is checked if this naming leads to errors in the employed formula due to parameter confusion. Additionally, the parameters are renamed to the more intuitive names.
