Nanotomography is a technique of growing importance in the investigation of the shape, size, distribution and elemental composition of a wide variety of materials that are of central interest to investigators in the physical and biological sciences. Nanospatial factors often hold the key to a deeper understanding of the properties of matter at the nanoscale level. With recent advances in tomography, it is possible to achieve experimental resolution in the nanometre range, and to determine with elemental specificity the three-dimensional distribution of materials. This critical review deals principally with electron tomography, but it also outlines the power and future potential of transmission X-ray tomography, and alludes to other related techniques.
纳米断层扫描技术在研究各种材料的形状、大小、分布及元素组成方面的重要性日益凸显，这些材料是物理和生物科学领域研究人员的核心关注点。纳米空间因素往往是深入理解纳米尺度物质特性的关键。随着断层扫描技术的最新进展，现已能够实现纳米级的实验分辨率，并以元素特异性确定材料的三维分布。本综述主要讨论电子断层扫描技术，同时也概述了透射X射线断层扫描技术的优势和未来潜力，并提及了其他相关技术。
