Text Correction

There was an error in the original publication [1]. Equation (1) was incorrectly typeset. The last term in the numerator of the error function (erf) should be σ²/τ.

A correction has been made to Section 2. Methods, Section 2.4. Optical Parameter Model, Equation (1). The correct equation is:

$$\begin{array}{c}MIRF\left(t\right)=\frac{A_1}{\sqrt{2\pi }\sigma }·\exp \left(-\frac{{\left(t-t_0\right)}^2}{2{\sigma }^2}\right)+\hfill \\ \hfill \frac{A_2}{2\tau }\exp \left(\frac{1}{2}{\left(\frac{\sigma }{\tau }\right)}^2-\left(t-t_0\right)/\tau \right)·\left(1+\mathrm{erf}\left(\frac{t-t_0-{\sigma }^2/\tau }{\sqrt{2}\sigma }\right)\right)+b\end{array}$$

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
