Monte Carlo simulation of skin dose distribution from interventional cardiology procedures


The project aims to develop and validate a Monte Carlo model to quantify the skin dose delivered over the surface of a simple geometrical phantom due to irradiation with an interventional cardiology x-ray system. The Monte Carlo model will then be used to assess the accuracy of skin dose maps calculated by the open-source software package openSkin (, which is integrated into the OpenREM patient dose management system ( Finally the Monte Carlo model will be used to quantify the difference in calculated skin dose when using a realistic humanoid phantom compared with using a simple geometric phantom as used by openSkin. The project may be extended to investigate the accuracy of radiation incidence maps produced by other systems such as GE Healthcare’s DoseWatch.
