Computer models of breast anatomy have been used in preclinical validation of breast cancer imaging systems. In this presentation we discuss a novel algorithm for simulation of breast tissue based on recursive partitioning of a 3D volume.

We provide mathematical basis for mechanisms of thickness control, accounting for partial volume effect (when a voxel contains multiple materials) and for asymptotic computational complexity of the algorithm. We demonstrate experimental results on various features of the simulation method and experimental evidence on theoretical complexity bounds.
