Proton therapy is different than traditional radiation therapy in the way the energy is delivered to the patient. With proton therapy, very little dose is delivered along the path prior to reaching the target. Instead protons deliver most of their energy at a prescribed, programmable distance inside the body, known as the Bragg Peak.
This type of treatment delivery differs from traditional radiation therapy, which deposits most of its energy near the surface of the body.
With precisely targeted proton therapy, clinicians can are better able to:
- Treat tumors surrounded by critical organs while sparing healthy tissues
- Reduce side effects common in traditional radiation therapy
Varian's ProBeam® system delivers this programmable depth of delivery using pencil beam scanning for precisely focused energy delivery and intensity-modulated proton therapy (IMPT).
