    1. Cerebral capillary flow imaging by wavelength‐division‐multiplexing swept‐source optical Doppler tomography

      Cerebral capillary flow imaging by wavelength‐division‐multiplexing swept‐source optical Doppler tomography
      Swept‐source optical coherence tomography has demonstrated the unique advantages for fast imaging rate and long imaging distance, however, limited axial resolution and complex phase noises restrict swept‐source optical coherence Doppler tomography (SS‐ODT) for quantitative capillary blood flow imaging in the deep cortices. Here, the wavelength‐division‐multiplexing optical Doppler tomography (WDM‐ODT) method, which divides a single interferogram into multiple phase‐correlated interferograms, is proposed to effectively ...

    2. Volumetric Doppler angle correction for ultrahigh-resolution optical coherence Doppler tomography

      Volumetric Doppler angle correction for ultrahigh-resolution optical coherence Doppler tomography
      Ultrahigh-resolution optical coherence Doppler tomography (ODT) demonstrates great potential for quantitative blood flow imaging owing to its large field of view and capillary resolution. However, ODT only detects the axial flow velocity and requires Doppler angle correction to retrieve the absolute velocity. Although methods for Doppler angle tracking of single or few large vessels have been reported, a method that enables angle correction of the entire 3D microvascular networks remains ...

    3. Ultrasensitive detection of 3D cerebral microvascular network dynamics in vivo

      Ultrasensitive detection of 3D cerebral microvascular network dynamics in vivo
      Despite widespread applications of multiphoton microscopy in microcirculation, its small field of view and inability to instantaneously quantify cerebral blood flow velocity (CBFv) in vascular networks limit its utility in investigating the heterogeneous responses to brain stimulations. Optical Doppler tomography (ODT) provides 3D images of CBFv networks, but it suffers poor sensitivity for measuring capillary flows. Here we report on a new method, contrast-enhanced ODT with Intralipid that significantly improves ...

    4. Optical coherence Doppler tomography for quantitative cerebral blood flow imaging

      Optical coherence Doppler tomography for quantitative cerebral blood flow imaging
      Optical coherence Doppler tomography (ODT) is a promising neurotechnique that permits 3D imaging of the cerebral blood flow (CBF) network; however, quantitative CBF velocity (CBFv) imaging remains challenging. Here we present a simple phase summation method to enhance slow capillary flow detection sensitivity without sacrificing dynamic range for fast flow and vessel tracking to improve angle correction for absolute CBFv quantification. Flow phantom validation indicated that the CBFv quantification accuracy ...

    6. Diagnosis of Bladder Cancer With Microelectromechanical Systems-based Cystoscopic Optical Coherence Tomography

      Objectives To examine the utility and potential limitations of microelectromechanical systems-based spectral-domain cystoscopic optical coherence tomography (COCT) so as to improve the diagnosis of early bladder cancer. Methods An optical coherence tomography catheter was integrated into the single instrument channel of a 22F cystoscope to permit white-light-guided COCT over a large field of view (4.6 mm wide and 2.1 mm deep per scan at 8 frames/s) and ...

    10. Optical coherence Doppler tomography quantifies laser speckle contrast imaging for blood flow imaging in the rat cerebral cortex

      Optical coherence Doppler tomography quantifies laser speckle contrast imaging for blood flow imaging in the rat cerebral cortex
      A dual-imaging modality is demonstrated for high-resolution quantitative imaging of local cerebral blood flow in the rat cortex by combining simultaneous spectral-domain Doppler optical coherence tomography (SDOCT) and full-field laser speckle contrast imaging (LSCI). Preliminary studies in tissue flow phantom and cocaine-induced cerebral blood flow changes indicated that by correlating coregistered cortical arterial blood flow, the relative measurement of flow changes by LSCI could be accurately calibrated by the absolute ...

    11. Optical Coherence Tomography: A Noninvasive Method to Assess Wound Reepithelialization

      Background Accurate assessment of wound healing may require invasive tissue biopsies, limiting its clinical usefulness in humans. Optical coherence tomography (OCT) is a novel, high-resolution method using light reflection to obtain noninvasive cross sectional imaging of biological tissues. ObjectivesTo evaluate the utility of OCT for assessing wound reepithelialization in a porcine model. MethodsThe authors conducted an animal study with two domestic pigs. Excisional cutaneous wounds were created over the ventral ...
