More About the 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.

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.
