Positron emission particle tracking (PEPT) is a noninvasive technique capable of imaging the three-dimensional dynamics of a wide variety of powders, particles, grains, and/or fluids. The PEPT technique can track the motion of particles with high temporal and spatial resolution and can be used to study various phenomena in systems spanning a broad range of scales, geometries, and physical states. We provide an introduction to the PEPT technique, an overview of its fundamental principles and operation, and a brief review of its application to a diverse range of scientific and industrial systems.
正电子发射粒子追踪（PEPT）是一种非侵入性技术，能够对各种粉末、颗粒、谷物和/或流体的三维动力学进行成像。PEPT 技术可以以高时间和空间分辨率跟踪粒子的运动，可用于研究跨越广泛尺度、几何形状和物理状态的系统中的各种现象。我们提供了对 PEPT 技术的介绍，概述了其基本原理和操作，并简要回顾了其在各种科学和工业系统中的应用。
