Requirements for the Loma Linda proton therapy accelerator
- Loma Linda University Medical Center, Loma Linda, California 92354 (United States)
More than eight years have passed since Loma Linda University Medical Center treated its first cancer patient with the world's first hospital based proton therapy accelerator. Using a synchrotron with extracted energies in the range of 70 to 250 MeV, nearly one hundred patients per day have been treated at the facility. Over the past five years, more than 97% of the patients received treatments on the day they were scheduled for irradiation. The activity schedules of accelerator maintenance and operations to maintain this patient load and accelerator reliability are presented in this paper. A typical 24-hour schedule of daily beam activities is presented. The specifications of what was needed in 1990 and what is needed now will also be discussed, as will an accelerator control system upgrade for achieving better intensity and energy control for more advanced dose localization. These new requirements include rapid energy and intensity changes within a patient treatment, fast beam abort systems, uniform beam spill, and energy control to better than 0.1%.
