The ETH Zurich Research Collection record carries the rights statement In Copyright, Non-Commercial Use Permitted (rightsstatements.org/page/InC-NC/1.0/), which states that no permission is required from the rights holders for non-commercial uses and that for other uses permission must be obtained. Availability is recorded as open access and the files download without registration. The readme deposited with the data states that all rights are reserved by the Laboratory of Movement Biomechanics, Institute for Biomechanics, D-HEST, ETH Zurich. Commercial use therefore requires permission, and redistribution is treated as restricted because the rights statement grants no explicit redistribution permission beyond non-commercial use. The MIT reference in the GitHub readme applies to the accompanying code, not to the dataset.

Verified against the ETH Zurich Research Collection item metadata, the deposited readme and license files, the project page at movement.ethz.ch and the documentation repository github.com/wjh19990923/Veriserum. The publication abstract reports approximately 110,000 X-ray images from 10 knee implant pair combinations, namely 2 femoral and 5 tibial implants, captured during 1,600 trials, with an automatically registered pose for every image and 200 images carrying manually registered poses for benchmarking. The repository readme describes 390 manually matched poses in the pose database, so the manual subset is reported differently in the two sources. Implant manufacturers and model names are not stated in the public metadata. The images are phantoms, so num_subjects is null; the target poses were derived from patient trials, but no patient images are included. The deposit is 2.74 GB and contains the image collection as a ZIP of JPEG frames named bs_ and fs_ per plane, an SQLite pose database, and bone and implant models as STL and NIfTI archives; acquisition logs inside the archive are dated 2021. Pose annotation does not fit the classification, segmentation or landmark label values, so labels remains none. The dataset is dual-plane fluoroscopy; the modality taxonomy has no fluoroscopy value, so it is recorded as XRAY, consistent with the other fluoroscopy record in this index. The dataset DOI is separate from the publication DOI. A range request on the image archive returned HTTP 206 with a valid ZIP header without authentication, so the download works.
