    5. Digital image correlation–based optical coherence elastography

      Digital image correlation–based optical coherence elastography
      Optical coherence elastography (OCE) provides deformation or material properties, mapping of soft tissue. We aim to develop a robust speckle tracking OCE technique with improved resolution and accuracy. A digital image correlation (DIC)-based OCE technique was developed by combining an advanced DIC algorithm with optical coherence tomography (OCT). System calibration and measurement error evaluation demonstrated that this DIC-based OCE technique had a resolution of 0.6 m displacement and ...

    6. In vivo feasibility of endovascular Doppler optical coherence tomography

      In vivo feasibility of endovascular Doppler optical coherence tomography
      Feasibility of detecting intravascular flow using a catheter based endovascular optical coherence tomography (OCT) system is demonstrated in a porcine carotid model in vivo. The effects of A-line density, radial distance, signal-to-noise ratio, non-uniform rotational distortion (NURD), phase stability of the swept wavelength laser and interferometer system on Doppler shift detection limit were investigated in stationary and flow phantoms. Techniques for NURD induced phase shift artifact removal were developed by ...

    7. Intraoperative handheld optical coherence tomography forward-viewing probe: physical performance and preliminary animal imaging

      Intraoperative handheld optical coherence tomography forward-viewing probe: physical performance and preliminary animal imaging
      A prototype intraoperative hand-held optical coherence tomography (OCT) imaging probe was developed to provide micron resolution cross-sectional images of subsurface tissue during open surgery. This new ergonomic probe was designed based on electrostatically driven optical fibers, and packaged into a catheter probe in the form factor of clinically accepted Bayonet shaped neurosurgical probes. Optical properties of the probe were measured to have a ~20 μm spot size, 5 mm working ...

    8. Comprehensive data visualization for high resolution endovascular carotid arterial wall imaging

      Comprehensive data visualization for high resolution endovascular carotid arterial wall imaging
      Carotid angioplasty and stenting is a minimally invasive endovascular procedure that may benefit from in vivo high resolution imaging for monitoring the physical placement of the stent and potential complications. The purpose of this pilot study was to evaluate the ability of optical coherence tomography to construct high resolution 2D and 3D images of stenting in porcine carotid artery. Four Yorkshire pigs were anaesthetized and catheterized. A state-of-the-art optical coherence ...

    9. Feasibility and methodology of optical coherence tomography imaging of human intracranial aneurysms: ex vivo pilot study

      Feasibility and methodology of optical coherence tomography imaging of human intracranial aneurysms: ex vivo pilot study
      Rupture of intracranial aneurysm is a common cause of subarachnoid hemorrhage. An aneurysm may undergo microscopic morphological changes or remodeling of the vessel wall prior to rupture, which could potentially be imaged. In this study we present methods of tissue sample preparation of intracranial aneurysms and correlation between optical coherence tomography imaging and routine histology. OCT has a potential future in the assessment of microscopic features of aneurysms, which may ...

    10. Biomechanical properties of soft tissue measurement using optical coherence elastography

      Biomechanical properties of soft tissue measurement using optical coherence elastography
      Optical Coherence Tomography (OCT) provides images at near histological resolution, which allows for the identification of micron sized morphological tissue structures. Optical coherence elastography (OCE) measures tissue displacement and utilizes the high resolution of OCT to generate high-resolution stiffness maps. In this work, we explored the potential of measuring shear wave propagation using OCE. A swept-source OCT system was used in this study. The laser had a center wavelength of ...

      Neurosurgical hand-held optical coherence tomography (OCT) forward-viewing probe
      A prototype neurosurgical hand-held optical coherence tomography (OCT) imaging probe has been developed to provide micron resolution cross-sectional images of subsurface tissue during open surgery. This new ergonomic hand-held probe has been designed based on our group's previous work on electrostatically driven optical fibers. It has been packaged into a catheter probe in the familiar form factor of the clinically accepted Bayonet shaped neurosurgical non-imaging Doppler ultrasound probes. The ...

    12. Endovascular optical coherence tomography intensity kurtosis: visualization of vasa vasorum in porcine carotid artery

      Endovascular optical coherence tomography intensity kurtosis: visualization of vasa vasorum in porcine carotid artery
      lication of speckle variance optical coherence tomography (OCT) to endovascular imaging faces difficulty of extensive motion artifacts inherently associated with arterial pulsations in addition to other physiological movements. In this study, we employed a technique involving a fourth order statistical method, kurtosis, operating on the endovascular OCT intensity images to visualize the vasa vasorum of carotid artery in vivo and identify its flow dynamic in a porcine model. The intensity ...

    13. Optical coherence elastography: current status and future applications

      Optical coherence elastography: current status and future applications
      Optical coherence tomography (OCT) has several advantages over other imaging modalities, such as angiography and ultrasound, due to its inherently high in vivo resolution, which allows for the identification of morphological tissue structures. Optical coherence elastography (OCE) benefits from the superior spatial resolution of OCT and has promising applications, including cancer diagnosis and the detailed characterization of arterial wall biomechanics, both of which are based on the elastic properties of ...
