“…It is also possible to accurately calculate the temporal field autocorrelation functions g 1 (τ) in the expression (15) by the reviewed MC technique 35 . Moreover, the results of phantom studies [36][37] and theoretical MC modeling carried out in terms of temporal field correlation function based on the DWS formalism show a good agreement between the experimental and theoretical results (Fig.6). Thus, the results presented in the course of current presentation demonstrate that MC approach described above is a convenient, can be suitable for any continuous optical diagnostic techniques, including optical/near-infrared spectroscopy, confocal microscopy, OCT, DWS and fluorescence spectroscopy 39 …”

A novel Monte Carlo (MC) technique for photon migration through 3D media with the spatially varying optical properties is presented. The employed MC technique combines the statistical weighting variance reduction and real photon paths tracing schemes. The overview of the results of applications of the developed MC technique in optical/near-infrared reflectance spectroscopy, confocal microscopy, fluorescence spectroscopy, OCT, Diffusing Wave Spectroscopy (DWS) and Doppler flowmetry are presented.

We combine diffusing wave spectroscopy and dynamic light scattering microscopy to simultaneous non-invasive imaging of skin blood microcirculation. We demonstrate for the first time to our knowledge that the local blood micro-flows and blood microcirculation can be observed and analyzed quantitatively at the the biological zero, when the arterial and vein flows are stopped completely. We show that the biological zero signal arises from the local blood micro-flows observed postmortem up to 100 minutes. The high sensitivity of diffusing correlation technique and the feasibility for non-invasive measurement of skin blood microcirculation is thus demonstrated, and the potential for methodology can now be explored.

High resolution imaged laser speckle strain gauge for vascular applications

An imaged laser speckle strain gauge that yields strain rates directly is described for vascular applications. The strain gauge does not rely upon cross correlations between a reference image and subsequent strain-modulated images as most current speckle interferometric methods do. Instead, it relies upon a two-dimensional frequency transform of "stacked speckle histories" which are time series of one-dimensional views of the speckle patterns arranged into a spatio-temporal array such that space is along the abscissa and time is along the ordinate. The tilt of the stacked speckle histories is related to the time rate of speckle pattern shift. The strain gauge is sensitive only to in-plane strains. Strain rates of 30.1 +/- 3.2 and 24.83 +/- 2.1 mu epsilon/s were evaluated in vitro on a fresh human tibial artery and rat inferior vena cava, respectively. The total strains measured were 21.6 and 19.86 mu epsilon, respectively. This is at least one order of magnitude more sensitive than other current soft-tissue strain measurement techniques.
