This study clarifies behavior and influence on dose distribution of carbon ion beam by magnetic field to realize real-time MRI-guided heavy ion therapy. We performed Monte-Carlo simulation that carbon ion beam is irradiated to water phantom in magnetic field, and evaluated the each influence on dose distribution by delta-ray and secondary particles.
