# **DoseRAD2026 structures**

Planning structures (binary masks, NRRD) for the 75 training patients of the [DoseRAD2026 dataset](https://huggingface.co/datasets/LMUK-RADONC-PHYS-RES/DoseRAD2026).

```
{photon,proton}/training/<patient_id>/structures/<structure>.nrrd
```

* Same folder layout and voxel grid as `image/ct.mha` and `dose/*.mha` in the main dataset.
* The structures follow the SynthRAD2025 CT before deformable registration to the MRI.
* Structure names are the original clinical names. Empty masks were removed.
* `viewer.csv` lists the structures per patient.
