Treatment planning for light ions: How to take into account relative biological effectivness (RBE)

A new treatment planning program was developed for the heavy ion therapy fa cility at GSI, which is tailored to the special needs for an active beam de livery using a magnetic raster scanner. It also includes a biological model for the estimation of biological effective dose for carbon ions and realiz es a fully biological treatment planning. Biological effective dose distrib utions and RBE maps can be displayed and assessed from the graphical user i nterface.
