Sub-second full-field tomographic microscopy at third-generation synchrotron sources is a reality, opening up new possibilities for the study of dynamic systems in different fields. Sustained elevated data rates of multiple GB/s in tomographic experiments will become even more common at diffraction-limited storage rings, coming in operation soon. The computational tools necessary for the post-processing of raw tomographic projections have generally not experienced the same efficiency increase as the experimental facilities, hindering optimal exploitation of this new potential. We present here a fast, flexible, and user-friendly post-processing pipeline overcoming this efficiency mismatch and delivering reconstructed tomographic datasets just few seconds after the data have been acquired, enabling fast parameter and image quality evaluation as well as efficient post-processing of TBs of tomographic data. With this new tool, also able to accept a stream of data directly from a detector, few selected tomographic slices are available in less than half a second, providing advanced previewing capabilities paving the way to new concepts for on-the-fly control of dynamic experiments.

在TOMCAT上进行实时数据层析成像的实时数据后处理。

第三代同步加速器源的亚秒级全场层析成像技术已成为现实，为研究不同领域的动力系统开辟了新的可能性。在断层摄影实验中，持续提高的数GB / s的数据速率在衍射受限的存储环上将变得更加普遍，即将投入使用。原始断层扫描投影的后处理所需的计算工具通常没有像实验设备那样获得相同的效率提升，从而阻碍了对这一新潜力的最佳利用。我们在这里提出了一种快速，灵活且用户友好的后处理流程，以克服这种效率不匹配问题，并在数据采集后仅几秒钟就提供重建的层析成像数据集，支持快速的参数和图像质量评估，以及对层析数据TB的高效后处理。借助这一新工具，该工具还能够直接从检测器接收数据流，因此不到半秒的时间就可以选择很少的断层切片，从而提供了先进的预览功能，为动态控制动态的新概念铺平了道路。实验。
