Impact of correlation between CT numbers and tissue parameters on Monte Carlo simulations: dosimetric aspects

Résumé

Monte Carlo (MC) simulation in radiotherapy is well known to be the reference for patient deposit dose estimation. Correlation between CT images and MC tissue parameters is a major step before the estimation of the deposit dose. It requires transforming the CT dicom images in the geometry input of MC code, and depends on the chosen samplings, which modify the CT number. However the CT number determine the density and the chemical composition of each voxel. The purpose of this study is to highlight the dosimetric impact of the density and the chemical composition variation.
