Roberts Proton Therapy Center

Roberts Proton Therapy Center

The Roberts Proton Therapy Center is the largest and most advanced facility in the world for this precise form of cancer treatment. The service is offered within Penn Radiation Oncology, which is a part of Penn's Abramson Cancer Center. Here, patients have access to one of science's most sophisticated weapons against cancer, seamlessly integrated with a full range of oncology services.

About the Proton Therapy Center

The Roberts Proton Therapy Center has the most advanced options available for patient positioning and comfort. It is made up of five treatment rooms that contain four gantries (90-ton rotational machines) designed to deliver therapeutic proton beams at the precise angle prescribed by the physician. There is also a room with a fixed-beam, as well as a room designated for research.

Unlike freestanding proton therapy facilities, this center is within Penn's Radiation Oncology department, which offers patients all types of radiation therapy options — as well as access to the latest clinical trials.

About 75,000-square feet in size, the Roberts Proton Therapy Center is located in a building connected to the Ruth and Raymond Perelman Center for Advanced Medicine. As many as 200 patients can be treated each day, making the Roberts Proton Therapy Center the largest such center in the world.

  • Proton therapy patients can wait for treatment in our spacious radiation oncology waiting room located on the concourse level of the Ruth & Raymond Perelman Center for Advanced Medicine. There is a separate waiting area directly next to the main waiting area that is specifically for pediatric radiation oncology patients.

  • The Roberts Proton Therapy Center is the world largest proton therapy center associated with an academic medical center in the world and one of only six such centers in the country. It is the world's most comprehensive proton therapy center, offering the unique ability to fully integrate conventional radiation treatment with proton radiation.

  • The Roberts Proton Therapy Center features five treatment rooms — four gantries with 90-ton rotational machines designed to deliver the therapeutic beam at the precise angle prescribed by the physician, and one fixed-beam room.

  • Proton therapy patients have access to private changing rooms directly across the hall from the proton treatment rooms.

  • Prior to proton therapy, patients will visit the Acuity room. The Acuity room, which is located in the same hallway as the proton treatment rooms, enables clinicians to effectively prepare and verify a patient's treatment plan prior to treatment.

  • Artwork in the hallway leading to one of the gantry rooms creates a calming environment for patients and their families.

  • A Penn Radiation Oncology tech in one of our four gantry rooms. Proton therapy is the most precise form of advanced radiation therapy available to treat certain cancers and other diseases.

  • Being embedded within an academic medical center opens up incredible research opportunities for Penn's world class clinicians and scientists. By leading the way in clinical trials, the Center will advance medical science through evidence-based research, providing new protocols for this groundbreaking form of cancer therapy.

The Roberts Proton Therapy Center is equipped by the Ion Beam Application, S.A. (IBA) company based in Louvain-la-Neuve, Belgium, and cost approximately $140 million. The building was designed by Tsoi, Kobus and Associates.
