Radio therapy: X-rays vs Ions

Using ions instead of x-rays for radiation therapy can decrease the damage of healthy tissue while still killing the tumor effectively. In the picture the dose distribution using 9 x-ray beams is compared to the dose distribution one gets using only two carbon ion beams. With the carbon beams most of the dose is deposited in the tumor and the healthy tissue around the tumor remains unharmed.
