Context: The CREATIS laboratory (Lyon, France) opens a Postdoctoral Research Fellowship in collaboration with the Université catholique de Louvain (Louvain-la-Neuve, Belgium) and an industrial partner. The position is funded by the Région Wallonne of Belgium.
Medical and scientific context: The objective of this project is to improve image quality in cone-beam computed tomography (CT) for image- guided radiotherapy (IGRT), with application to cone-beam CT in protontherapy. The proposed solution is an accurate modeling of x-ray physical interactions based on Monte Carlo simulations, embedded in high performance image reconstruction algorithms.
Goal and tasks: Mainly two categories of X-ray simulations have been proposed in the past: Monte Carlo and deterministic simulations. Recently, hybrid approaches have been proposed to improve computational efficiency while maintaining accuracy. The postdoctoral fellow will:
• Integrate hybrid simulations in the GATE platform for Monte Carlo simulations (based on Geant4),
• Model and experimentally validate a cone-beam CT system for protontherapy,
• Integrate the new simulations in CT reconstruction algorithms.
Profile:
• Education: The candidate must hold a PhD in medical imaging or radiation physics.
• Programming skills: C++.
• Experience: Monte Carlo simulations, tomographic reconstruction.
• Languages: English required, French optional.
• Location: Centre Léon Bérard, Lyon, France (90%) and Université Catholique de Louvain (10%), Louvain-la-Neuve, Belgium.
• Salary (gross): UCL salary scale, starting at 3500 euros / month.
