Abstract :
     Near-infrared diffuse correlation spectroscopy/tomography (DCS/DCT) are innovative techniques for continuous, non-invasive measurement and imaging of hemodynamics in relatively deep tissue (1 to 2 cm). They have been applied in monitoring tissue ischemia or hypoxia caused by various reasons such as surgical necrosis, ischemic stroke, cancers, and injuries, etc.
      In this talk, after a brief overview of the DCS theory and traditional instrumentation, I will present the recent optically extended noncontact DCS/DCT (ncDCS/ncDCT) technologies and their clinical and surgical applications for spectroscopic monitoring or 3D imaging of tissue blood flow. After that I will introduce the most innovative digital camera integrated speckle contrast DCT (scDCT) for fast 3D imaging of tissue blood flow distributions and speckle contrast DCS (scDCS) for wearable acquisition of tissue blood flow, as well as their medical applications in animals and humans. This talk will discuss the ncDCS/ncDCT, scDCS/scDCT instrumentation, data process, image reconstruction algorithm, validation methods and medical potentials in the perspective of physicians, surgeons or physiological researchers.
