In Vivo Pulse Wave Measurement Through a Multimode Fiber Diffuse Speckle Analysis System

Continuous monitoring of in vivo pulsatile blood flow and pulse wave velocity (PWV) is important for clinical applications. These parameters are correlated with physiological parameters, such as pressure elasticity vessels. A multimode fiber diffuse speckle contrast analysis (MMF-DSCA) system was developed fast measurement velocity. With MMF CCD sensor, the could be captured processed higher temporal resolution 3 ms. We also induced first time an MMF-DSCA evaluation PWV, which allows estimation continuously. To validate its performance, both phantom experiments were conducted. The results demonstrate that achieve detailed information profile Taking advantages being simple cost-effective, flexible can easily adapted continuous vital biosigns, heart rate, wave, pressure.
