The discovery of isotopic anomalies in the calcium- and aluminum-rich inclusions of the Allende meteorite has improved our knowledge of the origin of the solar system. Inability to find more inclusions without destroying the meteorite has hampered further study. By using a fourth-generation computed tomographic scanner with modifications to the software only, the interior of heterogeneous materials such as Allende can be nondestructively probed. The regions of material with high and low atomic numbers are displayed quickly. The object can then be cut to obtain for analysis just the areas of interest.
钙-铝富包体中同位素异常的发现增进了我们对太阳系起源的认识。由于无法在不破坏陨石的情况下找到更多的包体，进一步的研究受到了阻碍。通过使用第四代计算机断层扫描技术，仅对软件进行修改，就可以对非均质材料（如 Allende）的内部进行非破坏性探测。快速显示高原子序数和低原子序数的物质区域。然后可以对物体进行切割，以获得仅对感兴趣区域进行分析的材料。
