1. 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 a certain illuminated region in the body, and that the detection assembly collects light scattered from said certain region, measured data generated by the detection assembly being thereby indicative of scattered light having photons tagged and untagged by the acoustic radiation, thereby enabling to identify a light response of said certain region to illuminating light;

    a control unit connectable to the optical unit and to the acoustic unit, the control unit being preprogrammed to operate the acoustic unit 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 therefrom a data portion associated with the light response of said certain region, thereby enabling determination of a property of a tissue component in said certain region based on a relation between the measured data corresponding to the at least two different operating conditions of the acoustic unit.
