| # FLIP Ark+ tutorial chest X-ray classification splits |
|
|
| Synthetic chest X-ray DICOMs (768×768, 8-bit RGB) with Yes/No lesion labels, backing the Ark+ NVFLARE |
| tutorials in [FLIP](https://github.com/londonaicentre/FLIP) (Federated Learning Interoperability |
| Platform). |
|
|
| | Folder | Role | DICOMs | |
| |---|---|---| |
| | `site1/` | Site-1 training split — `arkplus_fine_tuning` | 1910 | |
| | `site2/` | Site-2 training split — `arkplus_fine_tuning` | 1872 | |
| | `site1_holdoff/` | Site-1 hold-out split — evaluation tutorials | 478 | |
| | `site2_holdoff/` | Site-2 hold-out split — evaluation tutorials | 468 | |
|
|
| Each folder contains: |
|
|
| - `accession-resources/<accession_id>/<accession_id>.dcm` — one DICOM per accession. |
| - `sample_get_dataframe_response.csv` — cohort dataframe: an `accession_id` column plus the lesion |
| label columns (`Effusion`, `Edema`, `Consolidation`, `Infiltration`, `Lung Nodule or Mass`, |
| `Pneumothorax`, `Lungs in normal arrangement`), valued `Yes`/`No`. |
|
|
| All images are **fully synthetic** (DeCaf `balanced_synthetic_split`) — no patient data. |
|
|
| ## Usage |
|
|
| The FLIP tutorials fetch these splits with `huggingface_hub.snapshot_download` and normalise them into |
| a gitignored local layout. From the FLIP repo root: |
|
|
| ```bash |
| make -C fl-tutorials download-arkplus-finetuning-data # site1 + site2 → data/arkplus/site{1,2}/ |
| make -C fl-tutorials download-arkplus-eval-data # hold-out splits → data/arkplus/site{1,2}_holdoff/ |
| ``` |
