MRI: Track 1 Acquisition of High-Speed Volumetric Particle Tracking System

该方案旨在获得一种高速体积颗粒跟踪测速系统(VTPV)，该系统能够跟踪测量流体体积内多个颗粒的三维位置，并随后计算颗粒的速度或加速度。将受益于该仪器的积极研究项目范围从血泵到微型医疗设备，再到环境中的微塑料运输。随着新的机会和合作，活跃的研究项目列表预计将会增加。拟议的系统将通过加强研究和教育的基础设施，提高罗切斯特理工学院进行尖端研究的能力。具体地说，罗切斯特理工学院和该地区计划的研究和培训包括(1)学生培训和研究，(2)两个新的多学科课程，和(3)培训讲习班。拟议的VTPV仪器由高强度激光照明、一套数码相机和专门的光学系统组成，这些光学系统集成了专用的同步硬件和图像处理软件。所描述的五个项目中的每个项目以前都受益于使用现有过时的2D测量系统获取二维流体或颗粒数据。拟议的三维高速系统将获得的新数据将增加对基本流动物理的定量理解，在某些情况下，还将提供有史以来第一个与应用相关的定量数据。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This proposal aims to acquire a High-Speed Volumetric Particle Tracking Velocimetric (VTPV) system capable of tracking the three-dimensional position of multiple particles within a measurement fluid volume, and subsequent calculation of velocity, or acceleration of the particles. Active research projects that would benefit from the instrument range from blood pumps to miniature medical devices to microplastics transport in the environment. The list of active research projects is expected to grow with new opportunities and collaborations. The proposed system will improve Rochester Institute of Technology’s ability to conduct leading-edge research by enhancing the infrastructure for research and education. Specifically, planned research and training at Rochester Institute of Technology and the region includes (1) student training and research, (2) two new multidisciplinary courses, and (3) training workshops. The proposed VTPV instrument is comprised of high intensity laser illumination, a set of digital cameras, and specialized optics that are integrated with dedicated synchronization hardware and image processing software. Each of the five projects described has previously benefitted from acquisition of two-dimensional fluid or particle data with the existing outdated 2D measurement system. The new data to be acquired by the proposed three-dimensional high-speed system will increase quantitative understanding of underlying flow physics, and in some cases, providing the first ever quantitative data relevant for the application.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
