CLINICAL EFFICACY

Clinical Efficacy of Proton Therapy.

Although proton therapy treatment was first proposed in 1954, it was not until 1990 that the first hospital-based proton treatment center opened. Today, more than 160,000 people worldwide have received proton therapy treatment, and the demand for treatment is unprecedented.

The following are research studies published between 2016 and 2018 that underscore the benefits of proton therapy for certain cancer patients. The majority of the studies employ pencil beam scanning, the most precise form of proton therapy.

ProTom’s Radiance 330® Proton Therapy System employs Fidelity Beam Scanning.  This pencil-beam scanning technology with gating capability enables the highest treatment precision.
