The theoretical benefits of particle beam therapy have been known for decades, but for many years complexity and cost delayed widespread adoption and slowed the creation of clinical evidence. The recent past has seen a proliferation of particle beam facilities, with more than 70 in operation worldwide, and a further 60 under construction or in planning stages. Notably among developed nations, Canada does not have such a facility nor have plans been announced. Recent innovations in beam delivery systems for protons could have significant impacts on capability and cost, but clinical evidence is required to support investments. This talk will review the physical and clinical rationale for proton beam therapy, along with methods of beam delivery and the implications for facility design.
- Describe the perceived physical advantages of particle beams for cancer treatment
- Indicate clinical scenarios that might benefit from proton therapy
- Describe methods of beam production and dose shaping
