三维粒子跟踪测速技术在流体动力学、燃烧和等离子体研究中正成为一种越来越重要的成像工具。我们介绍了一种动态离散层析成像算法，用于根据投影重建粒子轨迹。该算法是有效的数据从两个投影方向和准确的意义上说，它找到了一个解决方案与实验数据一致。可以检测解的非唯一性，并且可以单独跟踪解。
Particle tracking velocimetry in 3D is becoming an increasingly important imaging tool in the study of fluid dynamics and combustion as well as plasmas. We introduce adynamic discretetomography algorithm for reconstructing particle trajectories from projections. The algorithm is efficient for data from two projection directions and exact in the sense that it finds a solution consistent with the experimental data. Non-uniqueness of solutions can be detected and solutions can be tracked individually.
