Development and Operation of the Loma Linda University Medical Center Proton Facility

Abstract

The Proton Treatment Center at Loma Linda University Medical Center, the world's first hospital-based proton facility, opened in 1990 after two decades of development. Its early years were marked by a deliberately cautious approach in clinical utilization of protons, with intent to establish hospital-based proton therapy on a scientific basis. The facility was designed to be upgradeable, and development since 1990 has proceeded in three distinct phases of upgrades, both in technology and clinical applications. Upgrades continue, all of them based on an underlying program of basic and clinical research; future new applications of proton radiation therapy are expected to follow.
