Patent ID: 8277384

Claim:
A system for use in non-invasive in vivo determination of at least one desired parameter or condition of a subject having a scattering medium in a target region, said system comprising: (i) an illuminating system including at least one source of partially or entirely coherent light to be applied to the target region in said subject to cause a light response signal from the illuminated region; (ii) a detection system including at least one light detection unit configured for detecting time-dependent fluctuations of the intensity of the light response and generating data indicative of a dynamic light scattering (DLS) measurement; (iii) a control system configured and operable to receive and analyze the data indicative of the DLS measurement to determine said at least one desired parameter or condition, and generate output data indicative thereof; and a controllably operated pressurizing assembly configured and operable to affect a change in a blow flow.
