Patent ID: 8423116

Claim:
A measurement system for use for non-invasive measurements in a human body, the system comprising: a measurement unit comprising an optical unit having an illumination assembly; and a light detection assembly; and an acoustic unit for generating acoustic radiation; the measurement unit being configured and operable to provide an operating condition such that the acoustic radiation overlap with an illuminated portion within a region of interest in the body, and that the detection assembly collects light scattered from said region of interest and a region surrounding said region, measured data generated by the detection assembly being thereby indicative of scattered light having photons tagged by the acoustic radiation, and scattered light untagged by the acoustic radiation; and a control unit connectable to the optical unit and to the acoustic unit, the control unit being preprogrammed to operate the acoustic unit to tag volumes that substantially overlap in space with at least two different operating conditions to vary at least one characteristic of acoustic radiation, the control unit being responsive to the measured data and preprogrammed to process and analyze the measured data to extract from the measured data a data portion associated with the light response of said region of interest based on a relation between the measured data corresponding to the at least two different operating conditions of the acoustic unit, thereby enabling determination of a property of a tissue component in said region of interest.
