Top-notch machinery for excellent care


The compact proton therapy system transforming cancer treatment

Proton therapy is the most advanced radiotherapy treatment in existence, delivered using the most powerful medical device. By harnessing the specific physical characteristics of protons, proton therapy minimizes radiation exposure to healthy surrounding tissues, potentially leading to fewer side effects than traditional radiotherapy.

Help your patients 
keep everything but cancer

ProteusONE helps eligible cancer patients benefit from the exceptional clinical advantages of proton therapy over traditional radiotherapy, by precisely targeting the tumor while minimizing radiation exposure to healthy surrounding tissues.1,2 This helps preserve life beyond treatment, keeping everything but cancer.

Fewer adverse events, favorable quality of life and positive patient outcomes are some of the benefits of proton beam therapy.1-3 Its long-term positive impact is particularly beneficial for pediatric cancer patients or patients with complex cases of brain, head and neck or lung cancer, with irregular tumor anatomy and important sensitive organs-at-risk (OARs) that need to be preserved.3,4

  • Elevate your center’s clinical capabilities

    From routine to research, ProteusONE’s high modularity allows you to select the best configuration for your radiation oncology department: precise dose delivery with proton beam scanning (PBS) and dimensionally accurate cone beam computed tomography (CBCT) for image guided intensity modulated proton therapy (IMPT) as well as open gantry configuration supporting non coplanar treatment fields including vertex beams. Our cutting edge, clinically advanced technology helps improve time and quality during daily operations through its LINAC like workflow, streamlined quality assurance process and open choice of preferred ancillary partners** for optimal integration.

  • Change the lives of patients and staff

    ProteusONE’s precision helps spare critical organs and preserve a patient’s quality of life during treatment and beyond. The open-gantry configuration and the Philips Ambient Experience contribute to enhancing patient and staff satisfaction and working comfort. With a fast clinical ramp-up, staff can quickly gain confidence when using ProteusONE, helping them do more for their patients with this cutting-edge system. Additionally, the radiation oncology department could also benefit from a positive halo effect of an increased number of referred and treated patients, and more proton therapy-related research projects and grant opportunities. 5

User testimonials

Lane Rosen
Director at Radiation Oncology
Willis Knighton Cancer Center

Having the ProteusONE has changed the entire way we approach a patient. At the Willis-Knighton Cancer Center in Shreveport, LA, we wanted to offer the latest form of proton therapy, pencil beam scanning, while taking advantage of advances in image guidance and remaining within the budget of our hospital system. We needed assurances that our partner had experience in designing, installing, and maintaining a proton therapy facility but also had the financial strength to invest in research and development for the future. IBA has continually demonstrated innovation in the field of proton therapy and they were chosen for their unique ability to meet our department needs.
