ABOUT PRIMO

PRIMO performs full Monte Carlo simulation of radiation transport in the linac geometry and patient CT using either the general-purpose PENELOPE code or the fast Monte Carlo code DPM, all wrapped under an intuitive and hassle-free graphical user interface. PRIMO is free software.

What is PRIMO?

PRIMO is a dose verification system that simulates clinical linear accelerators (linacs) and estimates absorbed dose distributions in phantoms and computed tomographies.
