Abstract

In this study we evaluate the influences of optical property assumptions on near-infrared diffuse correlation spectroscopy (DCS) flow index measurements. The optical properties, absorption coefficient (µa) and reduced scattering coefficient (µs′), are independently varied using liquid phantoms and measured concurrently with the flow index using a hybrid optical system combining a dual-wavelength DCS flow device with a commercial frequency-domain tissue-oximeter. DCS flow indices are calculated at two wavelengths (785 and 830 nm) using measured µa and µs′ or assumed constant µa and µs′. Inaccurate µs′ assumptions resulted in much greater flow index errors than inaccurate µa. Underestimated/overestimated µs′ from −35%/+175% lead to flow index errors of +110%/−80%, whereas underestimated/overestimated µa from −40%/+150% lead to −20%/+40%, regardless of the wavelengths used. Examination of a clinical study involving human head and neck tumors indicates up to +280% flow index errors resulted from inter-patient optical property variations. These findings suggest that studies involving significant µa and µs′ changes should concurrently measure flow index and optical properties for accurate extraction of blood flow information.

(a) Hybrid fiber-optic probe comprised of: two DCS source fibers (785 and 830 nm) and four bundled DCS detector fibers separated by a distance of 1.5 cm; eight ISS source fibers (780 and 830 nm) and ISS detector fiber separated by distances of 2.0, 2.5, 3.0 and 3.5 cm (2 source fibers per separation distance). Note that two additional DCS detector fibers are shown, at 2.4 and 2.8 cm separations, but were not connected for this study. (b) Cartesian coordinates oriented for DCS source and detector (left) and liquid phantom setup (right) including: ~9.5 L glass aquarium (30.5 cm x 21.0 cm x 15.0 cm), hybrid optical probe and holder, and lab stand. (c) Typical correlation function fitting from a phantom experiment (μa (830 nm) = 0.05 cm−1, μs′ (830 nm) = 10 cm−1) with g1 derived from g2 measurements (g1m) using Eq. (1) and g1 calculated (g1c) using Eq. (3).

Stability of Brownian motion (DB-Einstein) during μa variation, depicted as means ± SDs (as error bars). Viscosity (a) is averaged from three samples corresponding to each step; temperature (b) and DB-Einstein (c) are averaged respectively over 5-minute intervals.

Measured optical properties with calculated DB-Einstein and DCS flow indices during μa variation. Left panels represent measurements obtained by Imagent and DCS at 830 nm. Right panels show measurements from Imagent at 780 nm and DCS DB calculations corresponding to 785 nm. All values shown, except predicted μa (a and d) and μs′ (b and e), are interval means ± SDs. Left panels: (a) μa (830 nm), (b) μs′ (830 nm), and (c) DB-Einstein (830 nm), DB-dynamic (830 nm), DB-mid (830 nm). Right panels: (d) μa (780 nm), (e) μs′ (780 nm), and (f) DB-Einstein (785 nm), DB-dynamic (785 nm), DB-mid (785 nm).

Tumor optical properties measured by Imagent at 830 nm and flow indices measured by DCS at 854 nm using 830 nm optical properties. Data were obtained from tumor region for 10 subjects with head and neck tumors. All values, except percent errors (d), shown are means ± SDs. (a) μa (830 nm), (b) μs′ (830 nm), (c) αDB-dynamic (854 nm), αDB-min (854 nm), αDB-mean (854 nm) and αDB-max (854 nm), and (d) % Error αDB-min (854 nm), % Error αDB-mean (854 nm) and % Error αDB-max (854 nm). Patients are listed in order of increasing αDB-dynamic (854 nm).
