The Study of Nail Bed Microcirculation by Laser SpeckleImaging Technique

The applicability of laser speckle contrast analysis technique for study of nail bed microcirculation parameters was investigated. Parameters and their dynamics were considered using calibration data obtained with biotissue phantom. Optimal conditions of formation and registration of speckle images were discussed and program for adaptive operation and processing was presented. The data of microscopic observations of nail bed capillary network was used to verify the results of speckle visualization.
