Positron emission particle tracking (PEPT) is a technique which allows the high-resolution, three-dimensional imaging of particulate and multiphase systems, including systems which are large, dense, and/or optically opaque, and thus difficult to study using other methodologies. In this work, we bring together researchers from the world’s foremost PEPT facilities not only to give a balanced and detailed overview and review of the technique but, for the first time, provide a rigorous, direct, quantitative assessment of the relative strengths and weaknesses of all contemporary PEPT methodologies. We provide detailed explanations of the methodologies explored, including also interactive code examples allowing the reader to actively explore, edit and apply the algorithms discussed. The suite of benchmarking tests performed and described within the document is made available in an open-source repository for future researchers.

正电子发射粒子追踪的最新进展：比较综述

正电子发射粒子跟踪 (PEPT) 是一种允许对粒子和多相系统进行高分辨率三维成像的技术，包括大型、密集和/或光学不透明的系统，因此难以使用其他方法进行研究。在这项工作中，我们汇集了来自世界上最重要的 PEPT 机构的研究人员，不仅要对该技术进行平衡和详细的概述和审查，而且首次对 PEPT 的相对优势和劣势提供严格、直接、定量的评估所有现代 PEPT 方法。我们提供了所探索方法的详细解释，包括交互式代码示例，使读者能够积极探索、编辑和应用所讨论的算法。
