XRAYN Public Vault

Every .md here becomes a page on xrayn.com. Medical imaging equipment encyclopedia — system cards, manufacturers, modalities, parts, field guides, glossary, clinical applications, regulatory reference.

Best way to browse: open dashboard.canvas for a visual dashboard, or press ⌘G for the graph view, or use an MOC page below.

Rules

• One System Card per variant. Always. No matter how small the difference.
• No fake data. No invented K-numbers, install-base counts, MAUDE counts, listings, vendor counts, prices.
• No specific service companies. Companies appear only after opting into the XRAYN seller/partner program.
• No scraped product imagery. OEM press kits, seller uploads, or silhouettes only.
• Engineer-credible voice. No marketing language ("cutting-edge", "seamless", "revolutionary").
• Graph is the product. Cross-link aggressively — manufacturer, modality, family, parts, field guide, glossary terms, clinical applications.
