A proton therapy facility comprises a variety of hardware and software components. IBA’s modular, flexible approach to facility design is scalable and adaptable to your specific goals. Whether you start with a larger center or with a single treatment room and add rooms as your practice expands, IBA can help you simplify the process.
IBA is at the forefront of developing the technology used in Proton Therapy systems. In fact, IBA leads the world in regulatory clearance for Proton Therapy systems, with FDA clearance in the United States, CE marking in Europe and SFDA clearance in China. From beam production to beam delivery, from patient positioning to treatment rooms and ancillary equipment, leading radiation oncology programs trust IBA as their partner.
A cyclotron accelerates protons to an extremely high speed, then generates a controlled beam that is directed by magnetic fields through a nozzle to the targeted tumor, releasing a dose of protons inside the tumor that kills cancer cells with minimal impact on surrounding healthy tissues. The proton beam can be contoured to the shape of the tumor, further decreasing radiation exposure to healthy cells and limiting side effects.
IBA recently introduced Vbeam® technology, which locates the cyclotron on a lower level, beneath treatment rooms. Protons are accelerated and transported vertically up to the treatment level, then directed horizontally into the treatment rooms.
The energy required for a particular treatment is transformed from the cyclotron energy using a variable Energy Degrader, along with the Energy Selection System (ESS).
The ESS transforms the fixed energy beam from the cyclotron into a variable energy beam, with a verified and controlled absolute energy, spread and emittance. This ensures optimal treatment precision. Degrading and scraping the beam in the ESS shields the patient from the neutrons that would otherwise be generated in the treatment room.
IBA has delivered more than 400 particle accelerators worldwide. As a result, IBA has mastered the learning curves associated with system design, installation and maintenance. The IBA Proteus® 235 particle accelerator is the most reliable and proven source of protons, providing the ability to modulate the proton beam current rapidly and accurately for unprecedented precision.
The Beam Transport and Switching System (BTS) consists of a series of powerful electromagnets that focus the proton beam as it leaves the cyclotron, transport it via a beam tube, and direct it to the entry point of each selected treatment room. The BTS is modular and scalable to your needs, allowing you to add additional treatment rooms to your facility as your practice grows.
The electromagnets in the BTS are directed from the main control room, based on the specific treatment being administered, which determines the energy and size of the beam.
With advances in imaging technology, physicians can pinpoint the exact location of most tumors. The goal then becomes delivering a lethal dose to the tumor while sparing healthy tissues. Placing the patient in the best position to receive the dose is a crucial part of administering Proton Therapy treatment. IBA is at the forefront of developing systems that support and position the patient with the accuracy needed to permit the proton beam to be delivered with great precision.
Standard Patient Positioner: Used with the EmPath Gantry Treatment Room, it provides more freedom of motion to move the patient so the target can be precisely positioned to receive the treatment beam.
Robotic Patient Positioning System (RPPS*): In addition to freedom of motion and pitch-and-roll capacity, the RPPS provides additional services such as water phantom handling or coupling of QA tools, and a further extension of the arm in the treatment room for more applications.
PatLog® Trolley System: Provides safe, comfortable, vibration-free patient transport, from setup in locations outside the treatment room, to different imaging devices and Proton Therapy rooms. The PatLog trolley features an autopilot system for secure transport, operator-controlled speed, optical tracking, and MR compatibility.

Because each tumor is unique, it presents specific challenges that require the most appropriate beam modality. To help ensure optimal treatment for each patient, IBA Proton Therapy systems include highly optimized nozzles to perform the best particle therapy treatments. Single Scattering, Double Scattering, Uniform Scanning and Pencil Beam Scanning. You can select all four modes or customize accordingly based on your specific clinic needs.
Single Scattering: Delivers a uniform proton dose in small fields with only one scatterer.
Double Scattering: Accepts any energy at nozzle entrance within the 70-235 MeV range. Reduces the distal falloff. Reduces the lateral penumbra and the radiation level.
Uniform Scanning: The beam spot is moved by magnetic scanning and allows several mini-irradiations. Full modulation, field uniformity, very safe treatment.
Pencil Beam Scanning: Slice-by-slice irradiation of the target with millimeter precision. Primary advantages include: multiple fast repainting, no use of aperture, no compensator devices, dose uniformity, intensity modulation (IMPT), and gating.
Optimized for throughput, the IBA Universal Nozzle gives you the flexibility to select the preferred beam delivery mode automatically within a single treatment room, without manual intervention. You can switch between all four modes (Single Scattering, Double Scattering, Uniform Scanning, Pencil Beam Scanning) from outside the room. This versatile system means you can use any room for any patient, which can maximize your capabilities and increase patient throughput. IBA is the only company with this unique, all-in-one integrated system.
See more detail on the Universal Nozzle.
Pencil Beam Scanning (PBS) uses a proton beam that is actively scanned throughout the target tumor volume. Compared to conventional passive scattering techniques, PBS provides improved three-dimensional conformity to the target. This allows for improved sparing of organs at risk and healthy tissues. IBA is the first company with a cyclotron-based Proton Therapy system to receive FDA approval for Pencil Beam Scanning. The technology was developed by IBA in close collaboration with the Francis H. Burr Proton Therapy Center at Massachusetts General Hospital in Boston.
