Non-Destructive Unrolling of Ancient Scroll via AI-Assisted X-ray Tomography

German scientists used 3D X-ray tomography and AI to virtually 'unroll' a delicate antique Buddhist scroll crafted by Mongolian nomads, preserving its fragile state. The centuries-old scroll, tightly wound within silk pouches, revealed its contents—a Tibetan Buddhist mantra written in Sanskrit script—without physical manipulation. The analysis also unexpectedly uncovered metal particles in the ink. While labor-intensive, this technique offers invaluable opportunities for studying otherwise inaccessible artifacts.
