Abstract
To provide clinically relevant insights into the device performance of an optical imaging approach to reconstruct the superficial cutaneous micro-circulation (skin angiography), a phantom device with turbid matrix and perfusable micro-vessels is essential. In this work, we describe a novel microfluidic-based device to mimic the micro-vessels and the turbid nature of the epidermis and dermis. This phantom device contains a hollow assay with a diameter of the channels of 50 μm. The hollow assay includes the geometry of the inlet, the river-like assay, and the outlet, which can be perfused by e.g. meta-hemoglobin solution. This imitates the superficial micro-circulation in the skin. The absorption coefficient μa and the reduced scattering coefficient μs' are adjusted to match those of skin. As an application case, we attempt to reconstruct a 2-D velocity field of the hemoglobin flow in the scattering microfluidic device via the Doppler-mode of an OCT.
