results for the simulations of a monocyte with LDs (Visualization 3). (a) Isolevel. From this visualization, the size and the positioning of the LDs can be seen, compared to the overall cell; (b) yz cut of the simulated 3D RI distribution. The non uniform distribution of RI into the LD can be noticed; (c) Histograms of the sphericity index, average RI and standard deviation values are evaluated for the LDs in a population of 50 monocytes. μ = mean value. σ = standard deviation. EM = External membrane, C = Cytoplasm, N = Nucleus, LD = Lipid Droplets. For each cell, the isolevels’ thresholds for the visualization are set with respect to the maximum value of the simulated RI profile.
