Does Slicer have information on the origin of the CT-Chest scan in the Sample Data module? The Help & Acknowledgement tab within the Sample Data module mentions where some of the other scans come from, but doesn’t mention anything for the CT-Chest scan. It would be helpful to know where the scan came from, if there’s any basic patient info for the CT-Chest scan, or if this scan has any limitations for use or licensing, etc.

I know this does not fully answer your question but in case it helps: the creators of Slicer never allow adding anything to the application that has any limitation in terms of licensing. So I’d say feel free to use the CT-Chest dataset as you wish.
