    2. Visual Prognosis of Eyes Recovering From Macular Hole Surgery Through Automated Quantitative Analysis of Spectral-Domain Optical Coherence Tomography (SD-OCT) Scans

      Visual Prognosis of Eyes Recovering From Macular Hole Surgery Through Automated Quantitative Analysis of Spectral-Domain Optical Coherence Tomography (SD-OCT) Scans
      Purpose : To determine the value of topographic spectral-domain optical coherence tomography (SD-OCT) imaging features assessed after macular hole repair surgery in predicting visual acuity (VA) outcomes. Methods : An automated algorithm was developed to topographically outline and quantify area, extent, and location of defects in the ellipsoid zone (EZ) band and inner retina layers in SD-OCT scans. We analyzed the correlation of these values with VA in longitudinal observations from 35 ...

    3. Optical Coherence Tomography of Pulmonary Arterial Walls in Humans and Pigs (Sus scrofa domesticus)

      Optical Coherence Tomography of Pulmonary Arterial Walls in Humans and Pigs (Sus scrofa domesticus)
      Pulmonary arterial hypertension (PAH) is a devastating disorder characterized by progressive elevation of the pulmonary pressures that, in the absence of therapy, results in chronic right-heart failure and premature death. The vascular pathology of PAH is characterized by progressive loss of small (diameter, less than 50 m) peripheral pulmonary arteries along with abnormal medial thickening, neointimal formation, and intraluminal narrowing of the remaining pulmonary arteries. Vascular pathology correlates with disease ...

    4. Automated, Depth Resolved Estimation of the Attenuation Coefficient From Optical Coherence Tomography Data

      Automated, Depth Resolved Estimation of the Attenuation Coefficient From Optical Coherence Tomography Data
      We present a method for automated , depth - resolved extraction of the attenuation coefficient from Optical Coherence Tomography (OCT) data . In contrast to previous automated , depth - resolved methods, the Depth - Resolved Confocal (DRC) technique derives an invertible mapping between the measured OCT intensity data and the attenuation coefficient while considering the confocal function and sensitivity fall-off, which are critical to ensure accurate measurements of the attenuation coefficient in practical settings (e ...

    5. Rapid scanning catheterscope for expanded forward-view volumetric imaging with optical coherence tomography

      Rapid scanning catheterscope for expanded forward-view volumetric imaging with optical coherence tomography
      We demonstrate a novel catheterscope, based on scanning fiber endoscopy, for volumetric imaging with optical coherence tomography (OCT), which possesses a high resonance frequency ( 2 kHz ) and a small outer diameter (OD) (1.07 mm). Our design is the fastest volumetric-scanning, forward-viewing catheterscope for OCT, and the scanning package has the smallest OD of any such OCT package published to date. Using a proof-of-operation catheterscope with commercial lenses, we demonstrate ...

    6. Miniature, minimally invasive, tunable endoscope for investigation of the middle ear

      Miniature, minimally invasive, tunable endoscope for investigation of the middle ear
      We demonstrate a miniature, tunable, minimally invasive endoscope for diagnosis of the auditory system. The probe is designed to sharply image anatomical details of the middle ear without the need for physically adjusting the position of the distal end of the endoscope. This is achieved through the addition of an electrowetted, tunable, electronically-controlled lens to the optical train. Morphological imaging is enabled by scanning light emanating from an optical coherence ...

    7. Polarization-sensitive interleaved optical coherence tomography

      Polarization-sensitive interleaved optical coherence tomography
      We introduce a new strategy for single-mode fiber based polarization-sensitive (PS-) optical coherence tomography (OCT) using orthogonally polarized optical frequency combs (OFC) in the sample arm. The two OFCs are tuned to be interleaved in the spectral domain, permitting simultaneous measurement of both polarization states from the same spatial region C close to the location of zero pathlength delay. The two polarization states of the beam in the sample arm ...

    9. Fabrication of anatomically tapered foveal pits for retinal phantoms for optical coherence tomography

      Fabrication of anatomically tapered foveal pits for retinal phantoms for optical coherence tomography
      Optical Coherence Tomography (OCT) has become a standard tool for diagnosing retinal disease in many ophthalmology clinics. Nonetheless, the technical and clinical research communities still lack a standardized phantom that could aid in evaluating and normalizing the various scan protocols and OCT machines employed at different institutions. Existing retinal phantoms designed for OCT imaging mimic some important features of the retina, such as the thickness and scattering properties of its ...
