**DoseRAD2026 dataset**

The DoseRAD2026 dataset is a large-scale, multimodal radiotherapy dataset designed to support the development and benchmarking of fast and accurate radiation dose calculation and prediction methods.

It accompanies the DoseRAD2026 real-time photon and proton dose calculation challenge.

**🗂️ Overview**

This dataset provides:

• Paired CT and MRI scans
• Beam-level Monte Carlo (MC)–simulated dose distributions (photon and proton)
• Beam configuration parameters

The training set, with 75 patients and corresponding dosemaps is publicly available on this repository.

The preliminary testing and testing sets are only accessible for evaluation of submissions to the challenge.

A detailed description of the dataset is provided here: https://doi.org/10.5281/zenodo.19347848
