The four Alpinion L3-8 phantom acquisitions in oslo/D_alpinion_phantom/ were acquired in 2017 by
Prof. Muyinatu A. Lediju Bell and Ole Marius Hoel Rindal at the PULSE Lab, Johns Hopkins University (JHU),
and are owned by JHU. Agreed with Prof. Bell and approved by JHU on October 23, 2026; the changes requested
in review (no D_ prefix, a self-contained jhu-pulselab/ collection) were approved by Prof. Bell on November 4, 2026. This PR:

• adds the jhu-pulselab/ collection: its card and figure, its own parameters.yaml and pipeline files, and
  jhu-pulselab/alpinion_phantom/ with the four files renamed JHU_Alpinion_L3-8_*.hdf5, their data card,
  pipeline.yaml and figures;
• deletes oslo/D_alpinion_phantom/;
• updates the Oslo collection card, oslo/parameters.yaml (without the moved acquisitions), the Oslo hero
  figure, and the Oslo sub-dataset cards (which now cite the USTB IUS 2017 paper instead of the Zenodo record).

In each HDF5 file only /metadata/credit and the root description and us_machine attributes change; the
channel data and all scan/probe parameters are byte-identical, and the file sizes are unchanged.

The matching GitHub PR, https://github.com/open-h/Open-H-RF/pull/58, adds jhu-pulselab/reconstruct.py and updates the website.

Hi @omrindal , thanks for correcting the JHU attribution.

• Since this is now a separate collection, please remove the D_ prefix from D_alpinion_phantom and update all references.
• Please make the JHU collection self-contained by placing its reconstruction script, parameters, and required pipeline files under jhu-pulselab/, while preserving reconstruction support for the remaining Oslo datasets.
• Please keep the HF and GitHub changes aligned.

Thanks!

Updated to address the review:

• The D_ prefix is dropped: the data now lives in jhu-pulselab/alpinion_phantom/, and all references are updated.
• jhu-pulselab/ is self-contained, with its own reconstruct.py, parameters.yaml and pipeline files.
• oslo/reconstruct.py is unchanged from main and still reconstructs the remaining Oslo datasets; oslo/parameters.yaml no longer lists the moved acquisitions.
• The GitHub PR (https://github.com/open-h/Open-H-RF/pull/58) and the Hugging Face PR (https://huggingface.co/datasets/nvidia/Open-H-RF/discussions/96) contain the same changes.

Please do not merge yet: these review changes are awaiting JHU's approval. I will comment here once JHU has approved.

Prof. Bell (JHU) has approved the review changes, so this is ready to merge from our side. Suggested merge order, as in the description: first the Hugging Face PR (https://huggingface.co/datasets/nvidia/Open-H-RF/discussions/96), then regenerate the website files with site/update.py, then the GitHub PR (https://github.com/open-h/Open-H-RF/pull/58).

Thanks @omrindal !
