LNS Superconducting Cyclotron in Catania is the
unique machine in in Italy and South Europe used
for protontherapy

Depth doses in radiotherapy single fields
4
Why clinical proton beams?

• penetration depth is well-defined and adjustable
• most energy at end-of -range
• protons travel in straight lines
• dose to normal tissue minimised
• no dose beyond target
