Accuracy and precision with Fidelity™ Beam Scanning.

Pencil-beam scanning with gating capability enables high treatment precision, improving long-term outcomes for patients and reducing side effects.1,2,3

Compact. Modular.

Smallest synchrotron footprint in the market and a modular/flexible design that includes interchangeable sub-systems; can be installed in purpose-built or existing facilities.

Integrated imaging.

Multiple imaging options including CBCT, 2-D X-ray with fluoroscopy, supporting image-guided radiotherapy (IGRT).

Treat any tumor site.

Clinical treatment energy range of 70-250 MeV allowing for proton therapy treatment of any tumor site in the body.

Supports single, multi-room and expandable configurations.

Supports single- or multi-room facilities, and can be configured to allow for future expansion.

Capable of imaging.

330 MeV capacity providing the accelerating capability for proton imaging of any anatomical area; dual-purpose beamline in development allowing for imaging and treatment with the same beam.

Clinical expert-designed user interface system.

User-friendly and efficient interface system designed by proton clinical experts.

Low radioactivation with Clean Beam.

Utilizing a synchrotron does not require beam degrading, as with cyclotrons.  Degrading causes secondary scatter radiation.  Our synchrotron produces beam at the energy required, thus it produces far fewer neutrons. This means fewer neutrons to the patient, staff, ancillary equipment, and the building; less shielding required; no cooling-off period needed before entering the vault for routine maintenance.
