Zusammenfassung: | A system and method are presented for use in monitoring one or more conditions of a subject's body. The system comprises a control unit which comprises an input port for receiving image data and data indicative of at least one external stimulation (external field) applied to a portion of the subject's body during collection of the image data therefrom, a memory utility, and a processor utility. The image data is indicative of a sequence of speckle patterns generated by the portion of the subject's body according to a certain sampling time pattern. The processor utility is configured and operable for carrying out the following: processing the image data utilizing the data indicative of the applied external field(s), said processing comprising determining a spatial correlation function between successive speckle patterns in the sequence, and determining a time varying spatial correlation function in the form of a time-varying function of at least one feature of the correlation function indicative of a change of the speckle pattern over time; selecting at least one parameter of the time-varying spatial correlation function, and applying to said at least one parameter one or more of the models to determine one or more corresponding body conditions; and generating output data indicative of said one or more corresponding body conditions. |
