Real-time swept source optical coherence tomography imaging of the human airway using a microelectromechanical system endoscope and digital signal processor

SPIE Digital Library (Jul 1 2008) Bronchoscopy, Endoscopy

Jianping Su, Jun Zhang, Lingfeng Yu et al. A fast-scan-rate swept laser for optical coherence tomography (OCT) is suitable to record and analyze a 3-D image volume. However, the whole OCT system speed is limited by data streaming, processing, and storage. In this case, postprocessing is a common technique. Endoscopic clinical applications pr ... [J. Biomed.

Optical Coherence Tomography of the Newborn Airway

annals.com (Jun 21 2008) Bronchoscopy

Objectives: Acquired subglottic stenosis in a newborn is often associated with prolonged endotracheal intubation. This condition is generally diagnosed during operative endoscopy after airway injury has occurred. Unfortunately, endoscopy is unable to characterize the submucosal changes observed in such airway injuries. Other modalities, such as magnetic resonance imaging, computed tomography, and ultrasound, do not possess the necessary level of resolution to differentiate scar, neocartilage, and edema. Optical coherence tomography (OCT) ...

Bronchoscopy for the Diagnosis and Staging of Lung Cancer

thieme-connect.com (May 29 2008) Bronchoscopy, Endoscopy

Bronchoscopy is an invaluable tool utilized for the diagnosis, staging, and management of lung cancer. Advancements in computer technology and engineering have allowed for the emergence of newer modalities to evaluate endobronchial, parenchymal, and mediastinal pathology. Established techniques such as white light video bronchoscopy and its ancillary procedures (forceps biopsy, brush biopsy, bronchoalveolar lavage, bronchial washings, and transbronchial needle aspiration) are discussed here, with their accuracy described in relation to ...

Respiratory gating of endoscopic OCT images of the upper airway

SPIE Digital Library (May 16 2008) Bronchoscopy, Endoscopy

Robert A. McLaughlin, Julian J. Armstrong, Sven Becker et al. Anatomical optical coherence tomography (aOCT) is an endoscopic imaging modality that can be used to quantify size and shape of the upper airway. We report the application of respiratory gating to aOCT images. Our results show that respiratory gating can reduce motion artefact in upper airway images ... [Proc.

In vivo Optical Coherence Tomography Imaging of Preinvasive Bronchial Lesions

Clinical Cancer Research (Apr 3 2008) Bronchoscopy, Endoscopy

Purpose: Optical coherence tomography (OCT) is an optical imaging method that can visualize cellular and extracellular structures at and below tissue surface. The objective of the study was to determine if OCT could characterize preneoplastic changes in the bronchial epithelium identified by autofluorescence bronchoscopy. Experimental Design: A 1.5-mm fiberoptic probe was inserted via a bronchoscope into the airways of 138 volunteer heavy smokers participating in a chemoprevention trial and 10 ...

Airway Wall Thickness Assessed Using Computed Tomography and Optical Coherence Tomography

ajrccm.atsjournals.org (Mar 5 2008) Bronchoscopy

Rationale: Computed tomography (CT) has been shown to reliably measure the airway wall dimensions of medium to large airways. Optical coherence tomography (OCT) is a promising new micron-scale resolution imaging technique that can image small airways two millimeters in diameter or less. Objectives: To correlate OCT measurements of airway dimensions with measurements assessed using CT scans and lung function. Methods: Forty-four current and former smokers received spirometry, CT scans and ...

This thesis describes the development, clinical validation and initial application of a technique for taking measurements of the shape and dimensions of the human upper airway, called anatomical optical coherence tomography (aOCT). The technique uses a transparent catheter containing a rotating optical probe which is introduced transnasally and positioned in the airway and oesophagus. Optical coherence tomography is used to take calibrated cross-sectional images of the airway lumen as the ...
