    摘要: A measurement system and method are presented for use for non-invasive measurements in a human body. Acoustic radiation is applied to a certain illuminated region in the body, with at least two different conditions of the applied radiation achievable by varying at least one characteristic of the acoustic radiation. Light scattered from the body part is detected, and measured data indicative of detected photons tagged and untagged by the acoustic radiation is generated. The measured data is analyzed to extract therefrom a data portion corresponding to the tagged photons and being therefore associated with a light response of said certain region, thereby enabling determination of tissue properties of said certain region based on a relation between the measured data portions corresponding to the at least two different operating conditions.

    摘要: A method and apparatus are presented for non-invasively monitoring at least one characteristic of a region of interest in a body. The body is illuminated by pulsed light to induce a photoacoustic effect. Acoustic radiation is detected, and measured data indicative thereof is generated. The photoacoustic effect is controlled by carrying out at least one of the following: providing the pulsed light of at least two different wavelength, analyzing the measured data to determine time variations of at least one predetermined parameter of a time dependent acoustic signal for each of wavelength, and determining oxygen saturation level in the region of interest; and operating a plurality of acoustic elements configured for detection of the acoustic radiation, to thereby define a focal volume for acoustic radiation detection to match dimensions of the region of interest.

    摘要: A method and system for noninvasive monitoring of at least one parameter of a region of interest in a human body. The system comprises a measurement unit and a control unit. The measurement unit comprises an optical unit having an illumination assembly (101A) and a light detection assembly (101B) to generate measured data indicative of collected light; and an acoustic unit (110) configured to generate acoustic waves of a predetermined ultrasound frequency range. The measurement unit provides an operating condition such that the acoustic waves overlap with an illuminating region within the region of interest and substantially do not overlap outside the region of interest. The measured data is indicative of scattered light having both ultrasound tagged and untagged light portions, enabling to distinguish between light responses of the region of interest and the region outside the region of interest.

    摘要: A method and system are presented for use in noninvasive monitoring at least one parameter of a region of interest in a human body. The system comprises a measurement unit and a control unit. The measurement unit comprises an optical unit having an illumination assembly configured to define at least one output port for illuminating light, and a light detection assembly configured to define at least one light input port for collecting light and to generate measured data indicative of the collected light; and an acoustic unit configured to generate acoustic waves of a predetermined ultrasound frequency range. The measurement unit is configured and operable to provide an operating condition such that the acoustic waves of the predetermined frequency range overlap with an illuminating region within the region of interest and substantially do not overlap with a region outside the region of interest, and that the detection assembly collects light scattered from the region of interest and light scattered from the region outside the region of interest. The measured data is thus indicative of scattered light having both ultrasound tagged and untagged light portions, thereby enabling to distinguish between light responses of the region of interest and the region outside the region of interest. The control unit is connectable to the optical unit and to the acoustic unit to operate these units, and is responsive to the measured data and preprogrammed to process and analyze the measured data to extract therefrom data indicative of a light response of the region of interest and determine the at least one desired parameter.

    摘要: Apparatus and methods are provided for monitoring a parameter of a region of interest (ROI) within a first tissue type within a body. A control unit drives a measurement unit to provide an operating condition such that acoustic waves overlap with a region within the ROI that is illuminated by illuminating light such as to generate a first set of tagged photons, and such that the acoustic waves overlap with a region of tissue within a second tissue type that is illuminated by illuminating light such as to generate a second set of tagged photons, the first and second sets of tagged photons being distinguishable from one another. The control unit determines the parameter of the ROI by extracting data portions associated with, respectively, the light response of the ROI and the light response of the second tissue type, by distinguishing between the sets of tagged photons.
