Performance of neutron beam system for accelerator-based boron neutron capture therapy

Abstract

A neutron beam system (NBS) based on an electrostatic proton accelerator designed for accelerator-based boron neutron capture therapy has been installed in Xiamen Humanity Hospital in China. The NBS has been used for patient treatments since October 2023, after more than a year of preliminary studies. By the end of 2024, more than 50 treatments had been executed. NBS uptime during 2024 was above 96%. Repeatability of the beam parameters was well within 2%. At present, configuration with only one treatment room operational, the overall machine usage, including clinical use, physics and dosimetry measurements, and biological experiments, has reached 27% of its capacity.
