Proton / Particle Therapy

Particle therapy is a type of external beam radiation therapy using heavier charged particles such as protons and carbon ions for advanced and highly precise cancer treatment. In contrast to photons and electrons, heavier particles exhibit a Bragg peak energy loss in the body, allowing the maximum radiation dose to be applied to the target area while minimizing damage to surrounding tissue.

A growing number of particle therapy centers, particularly proton therapy centers, are being established around the world to optimize radiation treatment for cancer patients. While most dosimetry tools used in classical radiotherapy centers can also be used in particle therapy centers, some specific requirements need to be addressed. Modern beam scanning systems come with gantry systems, and as the beam energy is a very crucial quantity in particle beam therapy, the requested scanning precision may be higher than in classical radiotherapy.

PTW offers a complete range of tools for reference dosimetry, machine QA and patient plan verification in particle therapy.
