Portable Laser Speckle Imaging System for Perfusion Imaging of Human Hand

摘要

In this study, we developed a new portable hand perfusion imaging system for rehabilitation evaluation based on laser speckle contrast imaging (LSCI). The new system measured perfusion changes in hand surface quantitatively. The hardware of portable imaging system consists of compact optical and electrical devices and is controlled by a user-friendly software interface. The software enables real-time perfusion image display and data plot of multiple region of interest. The portable system is applied to monitor the changes of hand perfusion during post-occlusive reactive hyperaemia (PORH) test.
