Abstract
Diffuse correlation spectroscopy (DCS) has emerged as a versatile, non-invasive method for deep tissue perfusion assessment using near-infrared light. However, in its standard form DCS suffers from significant signal-to-noise limitations. This has spurred a number of hardware developments seeking to address these SNR limitations and increase the quality and fidelity of measurements to support translation to use in both neuroscience and clinical applications. This talk will review a number of approaches being developed by our group including pathlength selective methods, long wavelength operation and the use of novel detector types.
