Research and Treatment

The Proton Therapy Center has more than doubled the nation's capacity to deliver proton beam radiation therapy, using state-of-the-art technology. It is only the third proton therapy center in the nation devoted to patient care. There are four centers involved in research.

Proton beams are more effective than traditional radiation therapy in destroying cancer cells in a precise manner while causing very little damage to healthy tissue. The earliest treatment protocols will be for prostate cancer patients. In addition, researchers anticipate that patients with head and neck cancers as well as pediatric cancers would benefit from the precision of this radiation treatment. The center works in close concert with the Center for Advanced Biomedical Imaging Research to locate and destroy cancer cells early in their development.


In a public/private partnership, Hitachi and other investors have constructed and equipped the $127 million facility. Other partners include the Houston-based financial services firm Sanders Morris Harris, Inc.; The Styles Company, a healthcare management and development firm; the Houston Firefighters’ Relief and Retirement Fund; the Houston Police Officers Pension System; General Electric; Varian Medical Systems; and IMPAC Medical Systems.
