Abstract

Purpose. The paper is devoted to Monte Carlo modeling of diagnostic X-ray procedure in order to estimate radiation doses to patients.

Methods. The Monte Carlo method implemented in the MCNP was used to simulate the interaction of X-ray radiation with different media. The TASMIP model was used for generating spectra of an X-ray tube with tungsten anode.

Findings. Mathematical model of X-ray unit including TASMIP was developed and verified. The values of the X-ray tube radiation yield were calculated using the Monte Carlo method. The ICRP voxel phantoms were adapted for modeling of X-ray examinations. The algorithm of estimating radiation doses to patients was implemented.

Application field of research. The created software product can be used for dosimetric assessments of radiodiagnostic procedures in treatment and prevention institutions.

Conclusions. The developed algorithm for assessing the radiation doses to patient's organs and tissues gives realistic results and should be used to prepare the set of dosimetric characteristics for the atlas of standard X-ray diagnostic procedures and for preparing interpolation models for on-line patient dose assessments.
