Microcomputer-based interactive tracking of blood cells at biomaterial surfaces

摘要

A microcomputer-based systems for analyzing the motion of human platelets and leukocytes at synthetic surfaces from a sequence of video frames on tape is described. The software is designed to provide convenient interaction with an operator to reduce the burden of manual analysis. In addition, the system computes and stores the cell movement data on disk for subsequent statistical analysis. Measurements include the number and nature of cell-to-surface collisions, residence times, and distances traveled.
