[Challenge] DoseRAD2026 – Real-Time 3D Radiation Dose Prediction (Photon & Proton, CT & MRI) — Great fit for MONAI pipelines

[FansomX]

Hi MONAI community,

We've just launched DoseRAD2026, a public challenge on real-time 3D radiation dose calculation from CT and MRI. Sharing here because the problem maps cleanly onto MONAI-based pipelines and we'd love to see people from this community participate.

Tasks

Four parallel tasks, all 3D dose prediction:

• Photon dose on CT (VMAT)
• • Photon dose on MRI (MR-linac)
• • Proton dose on CT
• • Proton dose on MRI

Inputs / Outputs

• Input: 3D CT or MRI volume + beam delivery parameters (MLC apertures for photons, pencil beam parameters for protons)
• • Output: beam-specific 3D dose distribution
• • Ground truth: high-fidelity Monte Carlo simulation

Why MONAI users might find it a good fit

• Standard 3D volumetric I/O — works directly with MONAI transforms and Dataset pipelines
• • Containerized submission on grand-challenge.org, same workflow as recent MICCAI challenges
• • Multimodal conditioning (volume + structured beam params) is a clean testbed for emerging architectures
• • Physics-informed and hybrid neural-numerical approaches are explicitly welcome

Organization

DoseRAD2026 is run by a consortium of European radiotherapy and medical physics groups — LMU Munich, University of Bern, PSI, GSI Darmstadt, DKFZ Heidelberg, UMC Utrecht, Amsterdam UMC, TU Delft, and Skåne University Hospital Lund.

Free to enter.
