一种自动化的三维粒子跟踪技术已经发展到研究颗粒在模拟流场中的运动。一个高速视频记录系统，柯达Ektapro 1000，具有两个相对正交的摄像机，用于这种技术。粒子跟踪数据进行比较，从轴对称狭窄模型的理论Poietille流和激光多普勒数据。粒子跟踪数据与理论和激光多普勒数据吻合良好，至少79%的粒子路径被成功确定。流体动力学特性通过这种技术得到的是：三维粒子路径，速度和粒子停留时间。
An automated three-dimensional particle tracking technique has been developed to study particle motion in modeled flow fields. A high speed video recording system, Kodak Ektapro 1000, with two cameras airanged relatively orthogonally is used for this technique. The particle tracking data are compared to theoretical Poiseuille flow and to laser Doppler data from an axisymmetric stenosis model. The particle tracking data are in good agreement with both theoretical and laser Doppler data, and at least 79 percent of the particle paths were determined successfully. Fluid dynamic properties derived by this technique are: 3-D particle paths, velocity, and particle residence time.
