Scanning the inner structure of cultural relics or fossils to observe the relative positions of the inner parts helps researchers deduce the evolution history and restore the natural and social features at that time.

The X-ray CT testing can help determine the inner corrosion of cultural relics and evaluate the remediation effect.

Meanwhile, the 3D CT imaging technology can also help conduct in-depth researches on the microfossils/fossils of animals and plants in ancient times, observe the 3D structure inside the fossils, overturn the existing inferences about some organisms, and refresh our understanding about the biological evolution history.
