  • System, method, and computer-accessible medium for subsurface capillary flow imaging by wavelength-division-multiplexing swept-source optical doppler tomography
    Patent number: 11771321
    Abstract: An exemplary system, method, and computer-accessible medium for generating an image(s) of an three-dimensional anatomical flow map(s) can include receiving an optical coherence tomography (“OCT”) signal(s), splitting the OCT signal(s) into a plurality of subspectra, averaging the plurality of subspectra, and generating the image(s) of the three-dimensional anatomical flow map(s) based on the averaged subspectra. The OCT signal(s) can be a swept-source OCT signal. The OCT signal(s) can be split into the subspectra based on a Hamming window. The Hamming distance window can be optimized to minimize a nearest side lobe for each of the subspectra. A position of at least one of the subspectra can be shifted prior to averaging the subspectra. The position of all but one of the subspectra can be shifted prior to averaging the subspectra.

  • Intralipid as a contrast agent to enhance subsurface blood flow imaging
    Patent number: 10531803
    Abstract: The present invention provides a method of imaging blood vessels or blood flow in blood vessels in an animal comprising: (i) injecting a lipid solution into the bloodstream of the animal; (ii) imaging the blood vessels by an imaging method; and (iii) calculating the blood flow velocity in the blood vessels.
