    2. Real-time high-speed volumetric imaging using compressive sampling optical coherence tomography

      Real-time high-speed volumetric imaging using compressive sampling optical coherence tomography
      Volumetric imaging of the Optic Nerve Head (ONH) morphometry with Optical Coherence Tomography (OCT) requires dense sampling and relatively long acquisition times. Compressive Sampling (CS) is an emerging technique to reduce volume acquisition time with minimal image degradation by sparsely sampling the object and reconstructing the missing data in software. In this report, we demonstrated real-time CS-OCT for volumetric imaging of the ONH using a 1060nm Swept-Source OCT prototype. We ...

    6. Automated segmentation of lung airway wall area measurements from bronchoscopic optical coherence Tomography imaging

      Automated segmentation of lung airway wall area measurements from bronchoscopic optical coherence Tomography imaging
      Chronic Obstructive Pulmonary Disease (COPD) affects almost 600 million people and is currently the fourth leading cause of death worldwide. COPD is an umbrella term for respiratory symptoms that accompany destruction of the lung parenchyma and/or remodeling of the airway wall, the sum of which result in decreased expiratory flow, dyspnea and gas trapping. Currently, x-ray computed tomography (CT) is the main clinical method used for COPD imaging, providing ...

    7. Alignment and calibration of high frequency ultrasound (HFUS) and optical coherence tomography (OCT) 1D transducers using a dual wedge-tri step phantom

      Alignment and calibration of high frequency ultrasound (HFUS) and optical coherence tomography (OCT) 1D transducers using a dual wedge-tri step phantom
      This paper introduces a novel alignment and calibration method for high frequency ultrasound (HFUS) and optical coherence tomography (OCT) 1D transducers. 2D images are constructed by means of translation of the transducers using a linear motor stage. Physical alignment of the transducers is needed in order to capture images of the same crosssectional plane, and calibration is needed to determine the relative coordinates of the images, including the image skew ...

    8. Central Airway Compliance in Asthma: Up or Down? Good or Bad?

      Central Airway Compliance in Asthma: Up or Down? Good or Bad?
      In this issue of the Journal, Williamson and coworkers (pp. 612–619) report on the use of anatomical optical coherence tomography(OCT) to measure the luminal area of central intrathoracic airways (generations 0–5) (1). By coupling this dynamic, in vivomeasurement with simultaneously measured transpulmonary pressure, they derived area–pressure relationships of these airwaysand calculated airway compliance (Caw) and specific compliance(sCaw). They then compared these values in control subjects ...

    9. Phenotyping Airways Disease With Optical Coherence Tomography

      Phenotyping Airways Disease With Optical Coherence Tomography
      Airway diseases are a major concern around the world. However, the pace of new drug and biomarker discovery has lagged behind those of other common disorders such as cardiovascular diseases and diabetes. One major barrier in airways research has been the inability to accurately visualize large and small airway remodeling or dysplastic/neoplastic (either pre or early cancerous) changes using non or minimally invasive instruments. The advent of optical coherence ...

non-uniform fast Fourier transform

      High-speed spectral domain 
optical coherence tomography using 
non-uniform fast Fourier transform
      The useful imaging range in spectral domain optical coherence tomography (SD-OCT) is often limited by the depth dependent sensitivity fall-off. Processing SD-OCT data with the non-uniform fast Fourier transform (NFFT) can improve the sensitivity fall-off at maximum depth by greater than 5dB concurrently with a 30 fold decrease in processing time compared to the fast Fourier transform with cubic spline interpolation method. NFFT can also improve local signal to noise ...

    11. Rapid Volumetric OCT Image Acquisition Using Compressive Sampling

      Rapid Volumetric OCT Image Acquisition Using Compressive Sampling
      Acquiring three dimensional image volumes with techniques such as Optical Coherence Tomography (OCT) relies on reconstructing the tissue layers based on reflection of light from tissue interfaces. One B-mode scan in an image is acquired by scanning and concatenating several A-mode scans, and several contiguous slices are acquired to assemble a full 3D image volume. In this work, we demonstrate how Compressive Sampling (CS) can be used to accurately reconstruct ...

    14. Quantitative Assessment of the Airway Wall Using Computed Tomography and Optical Coherence Tomography

      Ever since the site and nature of airflow obstruction in chronic obstructive pulmonary disease was described by Hogg, Thurlbeck, and Macklem, investigators have been looking for methods to noninvasively measure the airway wall dimensions. Recent advances in computed tomography technology and new computer algorithms have made it possible to visualize and measure the airway wall and lumen without the need for tissue. However, while there is great hope for computed ...
