Abstract
A novel near-infrared (NIR) diffuse correlation spectroscopy (DCS) has recently been developed for noninvasive monitoring of tumor blood flow during photodynamic therapy (PDT).DCS offers several attractive new features for tumor blood flow measurement such as noninvasiveness,portability,low cost,high temporal resolution and relatively large penetration depth.DCS technology has been utilized for continuous measurement of tumor blood flow before,during and after PDT in both animals and humans.The ultimate goal is to predict treatment outcomes from the measured tumor hemodynamic responses to PDT.
