| Summary: | Neutron capture therapy sets new requirements on the measurement and monitoring of the radiation fields used in this new form of therapy. Beams used for neutron capture therapy are comprised of mixed radiation fields which include slow, epithermal, and fast neutrons, as well as gamma rays. A computer-based beam monitoring system for epithermal or thermal neutron capture therapy is described. This system provides accurate, sensitive, and rapid on-line readout and recording of the various beam components. Readout of fluxes, fluences, and corresponding doses in the target are provided in color coded graphic analog as well as numerical form on the computer monitors. Variations in neutron spectrum or spatial distribution of the beam can be rapidly diagnosed with the aid of the monitor readout. Redundancy of fluence measurement is provided by an independent system using scalers and timers and by utilizing reactor power measuring instruments. |
