    Abstract: The present technology relates generally to systems and methods for in vivo visualization of lymphatic vessels. A system includes an optical coherence tomography (OCT) device and a computing device coupled to the OCT device configured to cause the OCT device to perform an OCT scan, generate image data in response to the OCT scan, and apply an eigendecomposition filter to the image data to produce processed image data. Alternatively or in addition, the computing device can compensate for scattering attenuation along an optical axis of the OCT scan in the image data set to generate compensated image data, enhance contrast of the compensated image data along a cross-section substantially orthogonal to the optical axis to generate contrast-enhanced image data, and identify at least one lymphatic vessel in the image data.

    Abstract: A method for imaging blood flow through target tissue is disclosed. An example method may include (a) directing a light beam at a blood-perfused target tissue, (b) reflecting the directed light beam off of static target tissue and flowing cells, (c) capturing a plurality of digital images of interference patterns of the reflected light in a plurality of successive frames, (d) measuring a light intensity of at least one pixel of each digital image, where the at least one pixel corresponds to an identical pair of coordinates in each successive frame, (e) comparing the measured light intensity of the at least one pixel of each digital image to the measured light intensity of the at least one pixel of an adjacent frame at the identical pair of coordinates and (f) determining a compiled light intensity for the at least one pixel for an aggregate motion contrast.

    Abstract: Systems and methods for determining microvascular functions in a sample of a subject are provided. A system obtains one or more spectral interference signals from the sample during one or more scans, extracts data from the spectral interference signals concerning cell, tissue, or particle motion within the sample via one or more optical microangiography algorithms, and calculates volumetric properties from the data indicative of fluid motion within the sample. The system and method may be used for diagnosing, providing a prognosis, or monitoring treatment of a disorder of the sample.
