I'm a PhD student at the Institute for Biomedical Imaging at Hamburg University of Technology (TUHH), Germany. My research focuses on parallel computing for medical imaging, particularly magnetic particle imaging. Since 2025, I have also worked as a software engineer at the Fraunhofer Research Institution for Individualised Medical Technology and Engineering (IMTE), Germany.
Session
Medical image reconstruction for modalities such as magnetic resonance imaging (MRI) and magnetic particle imaging (MPI) involves solving computationally intensive inverse problems. The MRIReco.jl and MPIReco.jl reconstruction packages feature a shared, modular optimisation backend that provides efficient and reusable solvers for various imaging modalities. In this talk, I will present how we extended this backend with vendor-agnostic GPU acceleration, which enables efficient reconstruction across both different imaging modalities and different GPU backends.
