François Vander Stappen

Product and research program manager
IBA industrial

With a background in electronic engineering and in medical physics, François started working for IBA 12 years ago, in proton therapy. After getting a deep experience on the field, he worked in R&D and led several research programs, aimed at improving the treatment accuracy. 

He joined in early 2020 the IBA Industrial business unit in the product management team. He works at developing a research program in collaboration with Aerial, bringing his experience of medical irradiations to the industrial domain. 


Monte Carlo is the state-of-the art technique for the simulation of particle transport, of their interactions with matter, and the dose deposition. It allows to predict the achievable dose uniformity depending on the irradiation parameters and the product properties. An excellent agreement with measurements has been shown. 

In this presentation we will show the potential of simulations, and use them to analyse the dose uniformity ratio for various configurations of products. We will compare the achievable uniformity in E-beam and X-ray. Specifically, we will study the impact of the density, shape and arrangement of food products like fruits and fresh vegetables.
