    2. 3D co-registration algorithm for catheter-based optical coherence tomography

      3D co-registration algorithm for catheter-based optical coherence tomography
      Applications of catheter-based optical coherence tomography (OCT) - originally developed for cardiovascular imaging - have expanded to other organ systems. However, currently available algorithms to co-register 3D OCT data to a second imaging modality were developed for cardiovascular applications and with it, are tailored to small tubular tissue structures. The available algorithms can often not be applied outside the cardiovascular system, e.g. when an OCT probe is introduced into the kidney ...

    7. Optical coherence tomography (OCT) detects collagen within the airway wall extracellular matrix

      Optical coherence tomography (OCT) detects collagen within the airway wall extracellular matrix
      Introduction: Airway diseases are characterized by structural airway remodeling, including extracellular matrix (ECM) changes. Although a key feature, no diagnostic test currently assesses airway remodeling other than invasive airway biopsies. Real-time optical coherence tomography (OCT) generates infrared-based cross-sectional images of airway segments. Previously we reported that OCT identifies and quantifies airway wall layers. We hypothesized that OCT is able to detect collagen deposition areas within the airway wall ECM. Methods ...

      Optical coherence tomography to detect acute esophageal radiation-induced damage in mice: a validation study
      Radiation therapy for patients with non-small-cell lung cancer is hampered by acute radiation-induced toxicity in the esophagus. This study aims to validate that optical coherence tomography (OCT), a minimally invasive imaging technique with high resolution (~10 m), is able to visualize and monitor acute radiation-induced esophageal damage (ARIED) in mice. We compare our findings with histopathology as the gold standard. Irradiated mice receive a single dose of 40 Gy at ...

      One‐to‐one registration of en‐face optical coherence tomography attenuation coefficients with histology of a prostatectomy specimen
      Optical coherence tomography (OCT), enables high‐resolution 3D imaging of the morphology of light scattering tissues. From the OCT signal, parameters can be extracted and related to tissue structures. One of the quantitative parameters is the attenuation coefficient; the rate at which the intensity of detected light decays in depth. To couple the quantitative parameters with the histology one‐to‐one registration is needed. The primary aim of this study ...
