Syncs the siemens-healthineers card, pipeline and figures on the Hub with the reviewed state on GitHub (open-h/OpenH-RF).

pipeline.yaml gains the parameters block the reference reconstructions were made with: a 36 x 35 mm field of view (the RF runs out at 40.7 mm), n_ch: 2 for the baseband IQ, all transmits, and a -60 dB dynamic range. The grid is 1014 x 986, which is isotropic at ~35.5 um in both directions; the stored data/image is itself exactly isotropic at 0.0791 mm, so the earlier implied grid stretched every reconstruction about 12% vertically against that reference.

Corrects the frame counts: 4,539 frames in total, 4,128 of them from the second acquisition round (Subjects 04-15), not 4,541 and 4,130. Acquisition and subject counts are unchanged.

Adds the four figures. assets/anatomies.png is the strip the card now leads with — four anatomies beamformed from data/raw_data — and assets/Subject_03_acq_008.gif is a ten-frame carotid loop whose caption points out that custom/contact marks frame 0 as off-subject, so per-frame flags should drive frame selection. The Data Validation paragraph ended mid-sentence where it referred to the reference B-modes; it now points at assets/. assets/main.png (release image) and assets/Subject_01_acq_006_recon.png come along for parity with the GitHub assets folder and are not embedded in the card.

The card also gains the zea process one-liner that renders any acquisition straight from the Hub.

Update — common card layout. The card now follows the layout shared by every OpenH-RF dataset: frontmatter with a name, a stand-alone title, the hero image with an italic caption linking the sample it shows, Description, Contributor(s), Creation Date and the standard CC BY 4.0 text, then a new Processing the Dataset section (the zea process command where the pipeline carries the whole reconstruction, and the reconstruct.py link) followed by Dataset Format, which opens with the zea version. Hard line breaks are gone so the Hub wraps paragraphs itself; the longer sections keep their content.

@tristan-deep Thanks for this. The carotid sample in the image looks almost like breast to me. Can you double check?

I see what you mean. It seems to be labeled carotid, at least! But best to check with Siemens. Check the summary output below, which reveals "carotid" under metadata.annotations.anatomy.

I have been improving README.mds, but in any case I have requested all teams to inspect and verify them.

LGTM pending contributor review.
