| FRXMH03 | Status of the Proton Therapy Complex Prometheus | 135 |
|
||
| The report overviews present status of the proton therapy complex Prometheus. The PTC Prometheus was developed and successfully implemented in the PhTC LPI RAS in conjunction with Protom Ltd. The complex is a Russian development and is fully produced within the territory of the Russian Federation. At the moment, there are two such complexes - in the city hospital of Protvino and in the A. Tsyb Medical Radiological Research Centre (MRRC). PTC LPI RAS and Protom ltd. along with MRRC have accumulated almost three years of experience in the usage of the complex under clinical conditions. PTC Prometheus has proved to be efficient and reliable in two years of clinical use in the treatment of head and neck cancer. If there is a developed infrastructure, the capacity of the facility will able go up to more than 1000 people a year. The low weight, low power consumption and compact dimensions of the complex allow it to be placed in ordinary hospitals, without constructing separate buildings. In addition to that, PTC Prometheus was licensed to irradiate the entire human body in March 2017. The phase of preparation of a modified immobilization system for irradiating a recumbent patient was completed by summer 2018. | ||

| TUPSA34 | Numerical Modeling and Development of the Prototype of the Bragg Peak Position Detector Working in Real Time Mode for Hadron Therapy Facilities | 220 |
|
||
| The purpose of this research was precision statistical simulation of multi-particle radiation transport using a realistic 3D model of clinical setup prototype and the systems of slot-hole collimators for on-line monitoring of Bragg-peak position at a proton therapy complex Prometheus to define of an available detecting accuracy and the choice of its optimum parameters. Numerical simulation of the experiments was carried out based on the RTS&T high-precision radiation transport software package using files of evaluated nuclear data from ENDF/B VIII.0 library. Results: To determine the error of the longitudinal Bragg peak monitoring, a series of 24 calculations was performed using different sequences of pseudo-random numbers to construct trajectories of particles in the calculation system. When using 3 slits, the RMS-error in determining the longitudinal coordinate was 1.5 mm. Keywords: radiation transport, Monte Carlo method, radiation therapy, medical accelerators, Bragg peak verification, mathematical modeling, irradiation planning, detection techniques. | ||

| WEPSB58 | Verification of Modern Evaluated Nuclear Data Libraries on the Basis of Integral Experiments Using the RTS&T Code System | 401 |

Over the past decade, there has been a significant update of the world's evaluated nuclear data libraries. The paper presents selected results of testing the current versions of these evaluated nuclear data libraries such as ENDF/B VII.1, ENDF/B VIII.0, ROSFOND, BROND 3.1, JENDL4.0u +, JENDL-4.0/HE, JENDL/HE 2007, CENDL 4.0, TENDL 2015, FENDL 3.0, JEFF 3.2 based on the integral experiments included in the Shielding Integral Benchmark Archive and Database (SINBAD) using the RTS&T* reference accuracy class code system. The RTS&T code uses continuous-energy nuclear and atomic evaluated data files to simulate of trajectories and discrete interactions of the particles in the energy range from thermal energy up to 20/150/3000 MeV. In current model development all data types provided by ENDF-6 format are takes account in the coupled multy-particle transport modeling. Universal data reading and preparation procedure allows to use various data file written in the ENDF-6 format. The ENDF data pre-processing (linearization, restoration of the resolved resonances, temperature dependent Doppler broadening of the cross sections and checking and correcting of angular distributions and Legendre coefficients for negative values are produced automatically with the PREPRO2017, NJOY2016, and GRUCON2017 code systems.
