摘要: Our purpose in the current study was to model an X-ray CT scanner with Monte Carlo (MC) method for gel dosimetry. In this study, a conventional one array detector modeled use of MCNPX MC code. The calculated photon fluence arrays used image reconstruction simple water phantom as well polyacrylamide polymer (PAG) radiation therapy. Image performed filtered back-projection Hann filter and Spline interpolation method. Using results, we obtained dose-response curve images irradiated at different absorbed doses. A spatial resolution about 2 mm found our simulated model. MC-based PAG showed reliable increase number increasing dose studied gel. Also, results that can be further studies on parameters influence usability reliability such energy spectra exposure techniques
