High-speed quantitative monitoring of highly-dynamic flow field (IMAGE)
Caption
a, A 8×6×3.5 cm silicone phantom was fabricated with a 6×4×2.5 cm well as container. The well was initially filled with liquid phantom (60 ml 1% intralipid) before monitoring. b, The halftone-SFDI was used to monitor the center of the liquid phantom with a 1×0.7 cm field-of-view. The monitoring was conducted at 1,000 Hz with 470 nm and 625 nm wavelengths. A dynamic flow with absorption and scattering contrasts was induced by injection of a solution made with nigrosin and 20% intralipid. c, The extracted absorption and reduced scattering maps, as well as chromophore maps at three representative time points are demonstrated for the quantitative monitoring of the flow field.
