| Popis: | In this paper we report a result of theoretical studies of the method for real-time monitoring of the Bragg peak position in a water phantom during scanned proton pencil-beam irradiation. This method is based on the detection of the prompt gamma rays emitted orthogonally to the beam direction produced as a result of inelastic nuclear interactions of primary particles. The principal parameters of the clinical setup prototype and the accuracy of determining the longitudinal coordinates of the Bragg peak position were found on the basis of statistical simulation using the RTS&T Monte Carlo multiparticle transport code. |
