LUNA16

Curated release of LUNA16 public lung CT nodule analysis data for research use.

Dataset viewer (Hugging Face)

The Dataset viewer loads data/train-00000-of-00001.parquet: an index of subject_id and ct_path for each case. NIfTI is not previewed in-browser; fetch volumes via Files.

An empty root metadata.csv was removed because it broke the Hub loader; the index is rebuilt from file paths.

OpenVAE / SMILE project

This dataset is published alongside the OpenVAE open-source stack for medical CT/MRI latent modeling and diffusion-style pipelines. The same public cohorts are used in our benchmarking and demo workflows.

• OpenVAE (code): github.com/KumaKuma2002/OpenVAE
• OpenVAE (pretrained VAEs on Hugging Face): huggingface.co/SMILE-project/OpenVAE
