In Monte Carlo simulations of light transport in tissues, a grid system is set up to score physical quantities. This study of cylindrically symmetrical problems found that the optimized radial and angular positions for the averaged physical quantities in each grid element are off‐center. The error of the extrapolated physical quantities at the light‐incidence point using the centered radial positions is up to 14.3%.
