Absorbed dose calculation for a realistic CT-derived mouse phantom irradiated with a standard Cs-137 cell irradiator using a Monte Carlo method.

Autor: Amir Entezam, Andrew Fielding, David Bradley, Davide Fontanarosa

Publikováno v: PLoS ONE, Vol 18, Iss 2, p e0280765 (2023)

Computed tomography (CT) derived Monte Carlo (MC) phantoms allow dose determination within small animal models that is not feasible with in-vivo dosimetry. The aim of this study was to develop a CT-derived MC phantom generated from a mouse with a xen

In-silico evaluation of the effect of set-up errors on dose delivery during mouse irradiations with a cell irradiator-based collimator system

Autor: Amir Entezam, Andrew Fielding, Gishan Ratnayake, Davide Fontanarosa

Set-up errors are a problem for pre-clinical irradiators that lack imaging capabilities. The aim of this study was to investigate the impact of the potential set-up errors on the dose distribution for a mouse with a xenographic tumour irradiated with

Purpose Preclinical radiotherapy applications require dedicated irradiation systems which are expensive and not widely available. In this work, a clinical dual source Cs-137 cell irradiator was adapted to deliver 1-cm diameter preclinical treatment b

Publikováno v: Radiation Physics and Chemistry. 189:109691

Tissue-equivalent phantoms are suitable tools for radiation dosimetry investigations. The goal of this study was to determine the scattered dose in a simple phantom model of a mouse with a xenographic tumour using experimental dose measurements and M
