The penetration characteristics of a proton therapy beam.
These benefits are increasingly being recognized. Reports and policies from governmental bodies in the Netherlands, the UK, Denmark, and other healthcare institutions have estimated that 15 to 20% of radiation therapy patients should benefit from proton therapy from both a clinical and economic perspective. At the same time, experience at renowned academic centers shows that when accessibility to the modality is not an issue, 45% of their radiotherapy patients are referred to Proton Therapy protocols. Scientists around the world are also researching the benefits of proton therapy, and, as a consequence, the number of scientific publications has grown exponentially in the last decade.
