Abstract
The present invention relates to a novel optical approach based on spatial analysis of spatial laser speckle patterns for tissue in-depth flow inspection characteristics. In particular, the invention relates to a technique for determining flow characteristics and identifying low blood flow or a blockage in blood vessels.
Claims15
A system for determining flow characteristics of an object, the system comprising a processing unit adapted for receiving a plurality of sequential secondary speckle patterns originated from at least a portion of the object by diffusive electromagnetic beam reflected from the object after being illuminated by an illumination source being placed at a certain distance from a surface of the object, processing the speckle data, wherein the processing of the speckle data comprises calculating a decorrelation decay time between each spatial point of said speckle data as a function of a distance from an illumination source, performing a statistical analysis of the spatial speckle data in a time-domain and generating statistical decorrelation data thereof being indicative of the flow characteristics of the object at different layers.
3-10. (canceled)
A method for determining flow characteristics of an object, the method comprising:
- receiving a plurality of sequential secondary speckle patterns originated from at least a portion of the object by diffusive electromagnetic beam reflected from the object after being illuminated by an illumination source being placed at a certain distance from a surface of the object;
- processing the speckle data to divide said sequential secondary speckle patterns into a plurality of time slices;
- calculating a decorrelation decay time between each spatial point as a function of a distance from the illumination source;
- performing a statistical analysis of the spatial speckle data in a time-domain;
- and
- generating statistical decorrelation data thereof being indicative of the flow characteristics of the object at different layers.
