Fig. 4: RI tomography of various cell-type spheroids by in-silico clearing RI tomography.

Maximum intensity projection (MIP) and cross-sections of RI maps for (a) HepG2, (b) A549, (c) A172, and (d) F9 spheroids. The depth of the cross-sections is denoted by white dashed lines in the MIP images; 3D rendering by alpha blending of RI distributions for (e) HepG2, (f) A549, (g) A172, and (h) F9 spheroids. The movies showing all cross-sections are provided in Supplementary Videos 2 and 3
