    1. Optical coherence tomography-guided laser marking with tethered capsule endomicroscopy in unsedated patients

      Optical coherence tomography-guided laser marking with tethered capsule endomicroscopy in unsedated patients
      Tethered capsule endomicroscopy (TCE) is an emerging screening technology that comprehensively obtains microstructural OCT images of the gastrointestinal (GI) tract in unsedated patients. To advance clinical adoption of this imaging technique, it will be important to validate TCE images with co-localized histology, the current diagnostic gold standard. One method for co-localizing OCT images with histology is image-targeted laser marking, which has previously been implemented using a driveshaft-based, balloon OCT catheter ...

    2. Automated segmentation and characterization of esophageal wall in vivo by tethered capsule optical coherence tomography endomicroscopy

      Automated segmentation and characterization of esophageal wall in vivo by tethered capsule optical coherence tomography endomicroscopy
      Optical coherence tomography (OCT) is an optical diagnostic modality that can acquire cross-sectional images of the microscopic structure of the esophagus, including Barretts esophagus (BE) and associated dysplasia. We developed a swallowable tethered capsule OCT endomicroscopy (TCE) device that acquires high-resolution images of entire gastrointestinal (GI) tract luminal organs. This device has a potential to become a screening method that identifies patients with an abnormal esophagus that should be further ...

    3. Static and dynamic crystalline lens accommodation evaluated using quantitative 3-D OCT

      Static and dynamic crystalline lens accommodation evaluated using quantitative 3-D OCT
      Custom high-resolution high-speed anterior segment spectral domain Optical Coherence Tomography (OCT) provided with automatic quantification and distortion correction algorithms was used to characterize three-dimensionally (3-D) the human crystalline lens in vivo in four subjects, for accommodative demands between 0 to 6 D in 1 D steps. Anterior and posterior lens radii of curvature decreased with accommodative demand at rates of 0.73 and 0.20 mm/D, resulting in an ...

    4. 3D imaging for faster diagnosis of esophageal disease

      3D imaging for faster diagnosis of esophageal disease
      A tethered capsule that is swallowed by the patient offers a quick and pain-free method of screening and diagnosing gastrointestinal diseases. Diagnosing gastrointestinal (GI) diseases usually involves endoscopy, combining an invasive probe and video imaging or other optical methods. While effective, this method often causes patient discomfort and typically requires anesthesia, making it costly and time-consuming. Here we describe a new option for screening using a swallowable optomechanically engineered pill ...

      Pill-sized device rivals endoscopy: Novel imaging system screens for Barrett’s esophagus in minutes
      ...on usually caused by chronic exposure to stomach acid. Researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH) have developed an imaging system enclosed in a capsule about the size of ...

    6. Tethered capsule endomicroscopy enables less invasive imaging of gastrointestinal tract microstructure

      Tethered capsule endomicroscopy enables less invasive imaging of gastrointestinal tract microstructure
      Here we introduce tethered capsule endomicroscopy, which involves swallowing an optomechanically engineered pill that captures cross-sectional microscopic images of the gut wall at 30 m (lateral) 7 m (axial) resolution as it travels through the digestive tract. Results in human subjects show that this technique rapidly provides three-dimensional, microstructural images of the upper gastrointestinal tract in a simple and painless procedure, opening up new opportunities for screening for internal diseases.
