SYSTEM AND METHOD FOR IN VIVO MEASUREMENT OF BIOLOGICAL PARAMETERS
First Claim
1. 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;
(ii) a detection system including at least one light detection unit configured for collecting time-dependent fluctuations of the intensity of the light response and generating data indicative of the DLS measurement; and
,(iii) a control system configured and operable to analyze the data indicative of the DLS measurement to determine said at least one desired parameter or condition, and generate output data indicative thereof.

Abstract
A system, method and medical tool are presented 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. The measurement system comprises an illuminating system, a detection system, and a control system. The illumination system comprises at least one light source configured for generating partially or entirely coherent light to be applied to the target region to cause a light response signal from the illuminated region. The detection system comprises 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. The control system is configured and operable to receive and analyze the data indicative of the DLS measurement to determine the at least one desired parameter or condition, and generate output data indicative thereof.

14. An optical method for use in determining in vivo hemorheological chemical and physiological parameters of a subject, the method comprising:
-
(i) applying partially or entirely coherent light to a subject region in said subject to cause a light response signal from the target region; (ii) detecting fluctuation dependent speckle pattern of the light response signal over a predetermined frequency interval, and generating data indicative thereof, (iii) processing the detected data by using temporal autocorrelation intensity analyzing or power spectrum analyzing; and
;(iv) determining at least one desired parameter or condition of said subject from the time-fluctuation of a dynamic light scattering (DLS) signal. - View Dependent Claims (15, 16, 17, 18, 19)
