f_\text{GNP} = exp(- \frac{(X-x_j)^2}{2 \sigma^2})  \end{equation}  where $(X-x_j)^2$ represents the minimal distance from each voxel \textit{i} of the normal tissues to the tumor region. Different values of sigma were considered to evaluate the distribution: in particular, $\sigma = 0 \ mm$ (relative to a precise concentration of GNPs inside the tumor volume alone), and $\sigma = 5, 10, 20, 30, 50 \ mm$ (relative to increasingly defective distributions with increasing number of GNPs in the normal tissues surrounding the tumor). Also, different values of the maximum number of nanoparticles to be found inside the tumor volume, each relative to a nominal concentration of GNPs, were considered.
