Abstract

We present a laser speckle contrast imaging (LSCI) device equipped with an image conduit to image microvascular blood flow in remote tissues like ear, nose, throat (ENT) and cervical region. The system is validated using a tissue mimicking microfluidic flow phantom with different widths and flow speeds. The proposed system is being developed as a point of care testing (POCT) device best suited for at-home self-monitoring in resource-limited areas as it is non-invasive, portable, affordable and real time.
