Our Technology, Your Future.

Leveraging innovation, expertise, and passion, we are raising the bar for proton therapy technology.

The Radiance 330® Proton Therapy System delivers vanguard proton therapy treatment with the precision of pencil beam scanning and the power of integrated imaging.

Radiance 330® is compact and customizable. This allows us to install Radiance 330® in locations other systems cannot be installed.

And with low capital and operating costs, Radiance 330® delivers fast return on investment.

Discover The RADIANCE 330® Proton Therapy System

Compact Synchrotron Footprint.

The Radiance 330® has the smallest synchrotron footprint in the market.

Synchrotrons have low secondary neutrons and scatter radiation, which lowers the risk of unnecessary and unwanted radiation to the patient and facility.

Pencil Beam Scanning.

Radiance 330® delivers proton therapy treatment with the precision of pencil beam scanning, the most advanced form of proton therapy treatment.

Pencil beam scanning delivers superior dose sculpting and higher beam efficiencies than other methods of proton beam delivery. This reduces unwanted side effects, improves long-term outcomes for patients, and improves the patient’s quality of life.1,2,3

Fidelity Beam Scanning.

The Radiance 330® is equipped with ProTom’s Fidelity Beam Scanning System, which uses matrix spot scanning. This type of scanning accurately “paints” a tumor with the prescribed dose using beam energy variations to control penetration depth and magnetic steering to guide lateral dose deposition.


A modular design that includes interchangeable sub-systems allows for Radiance 330® to be installed in purpose-built or existing facilities. This design also allows for future expansion and for the upgrade of individual components.

Single, multi-room and expandable configurations.

Radiance 330® supports single, multi-room and expandable configurations. The beam transport system is a beamline that guides the proton beam from the synchrotron to the treatment room and is expandable to as many as three treatment rooms.

Integrated imaging.

Radiance 330® is designed to interface with in-room imaging solutions, such as computed tomography or cone-beam computed tomography. It’s also equipped with orthogonal imaging, including image-registration software, which generates a 6 degree of freedom patient-alignment correction vector.

Proton Imaging.

330 MeV capacity makes R330 the only system on the market capable of imaging any area of the body.

Clinical expert-designed user interface system.

Experienced users of a variety of proton beam therapy systems were consulted in the design of the control system. That empirical information was used to integrate workflow guidance into the operator controls, enabling radiation therapists to spend less time interacting with the equipment and more time focusing on the patient.
