A detailed 3D investigation of nanoparticles at a local scale is of great importance to connect their structure and composition to their properties. Electron tomography has therefore become an important tool for the 3D characterization of nanomaterials. 3D investigations typically comprise multiple steps, including acquisition, reconstruction, and analysis/quantification. Usually, the latter two steps are performed offline, at a dedicated workstation. This sequential workflow prevents on-the-fly control of experimental parameters to improve the quality of the 3D reconstruction, to select a relevant nanoparticle for further characterization, or to steer an in situ tomography experiment. Here, an efficient approach to overcome these limitations is presented, based on the real-time reconstruction of arbitrary 2D reconstructed slices through a 3D object. Implementation of this method may lead to generalized implementation of electron tomography for routine nanoparticle characterization in 3D.

用于纳米颗粒定量和原位 3D 表征的任意切片的实时重建

在局部尺度上对纳米粒子进行详细的 3D 研究对于将它们的结构和组成与其特性联系起来非常重要。因此，电子断层扫描已成为纳米材料 3D 表征的重要工具。3D 调查通常包括多个步骤，包括采集、重建和分析/量化。通常，后两个步骤是在专用工作站上离线执行的。这种顺序工作流程可防止对实验参数进行实时控制，以提高 3D 重建的质量、选择相关纳米粒子以进行进一步表征或指导原位断层扫描实验。在这里，提出了一种克服这些限制的有效方法，基于通过 3D 对象实时重建任意 2D 重建切片。这种方法的实施可能会导致电子断层扫描的普遍实施，用于 3D 中的常规纳米颗粒表征。
