We improved the particle transport simulation code PHITS to be capable of estimating the microdosimetric PDs in macroscopic area, by means of incorporating a mathematical function that can instantaneously calculate the PDs around the trajectory of HZE particles with precision equivalent to a microscopic track-structure simulation. A new method for estimating biological dose, a product of physical dose and RBE, from charged-particle therapy was established, using the improved PHITS coupled with a microdosimetric kinetic model.
