      Feature Of The Week 03/01/15: Three-dimensional Imaging and Analysis of Human Cartilage Degeneration Using Optical Coherence Tomography

      Optical Coherence Tomography (OCT) is an evolving imaging technology allowing non-destructive imaging of cartilage tissue at near-histological resolution. In this study, the diagnostic value of 3-D OCT in comparison to 2-D OCT in the comprehensive grading of human cartilage degeneration is investigated. In total, 53 human osteochondral samples were harvested. The imaging was performed by obtaining a single B-scan image (2-D OCT) and by collecting 100 consecutive B-scan images to generate a volumetric data set (3-D OCT). OCT images were assessed qualitatively according to a modified version of the DJD classification. OCT images were assessed quantitatively by algorithm-based evaluation of ...

    5. Real-time OCT guidance of an ablation laser for advancement in the fight of atherosclerotic cardio-vascular disease

      Real-time OCT guidance of an ablation laser for advancement in the fight of atherosclerotic cardio-vascular disease

      Real-time OCT guidance of an ablation laser has now been developed for use in the treatment of atherosclerotic cardio-vascular disease. DWH Systems, Inc. of Seminole Florida working with ELAN Vascular Technologies has developed a system whereby three OCT imaging heads monitor a femtosecond ablation laser in real-time, to perform micro ablation on the outer surface of diseased arteries. OCT is used first to acquire a 3D, C-scan map of the diseased portion of an artery then develops an ablation map for the system to follow. As ablation is performed, OCT again monitors the lasers cutting process from multiple angles in ...

      Feature Of The Week 02/22/15:  Case Western Reserve University Demostrates Using OCT to Rapidly Phenotype and Quantify Congenital Heart Defects Associated with Prenatal Alcohol Exposure

      The most commonly used method to analyze congenital heart defects involves serial sectioning and histology. However, this is often a time-consuming process where the quantification of cardiac defects can be difficult due to problems with accurate section registration. Here we demonstrate the advantages of using optical coherence tomography, a comparatively new and rising technology, to phenotype avian embryo hearts in a model of Fetal Alcohol Syndrome where a binge-like quantity of alcohol/ethanol was introduced at gastrulation. The rapid, consistent imaging protocols allowed for the immediate identification of cardiac anomalies, including ventricular septal defects and misaligned/missing vessels. Interventricular septum ...

      Feature Of The Week 02/15/15: Optical Coherence Tomography Identifies Lower Labial Salivary Gland Surface Density in Cystic Fibrosis

      Cystic fibrosis (CF) is a genetic disease that affects multiple organs due to the production of abnormally viscous mucus. Recurring pulmonary infections result in build-up of lung damage which leads to death. Intestinal, pancreatic, and hepatobiliary complications also occur, further aggravating the course of the disease. The molecular basis of CF is the dysfunction of the CF transmembrane conductance regulator (CFTR). CFTR-related disruption of transmembrane ion transport affects the exocrine glands, among which are the labial salivary glands (LSGs). Optical coherence tomography (OCT) enables non-invasive visualization of the internal structures of tissues at micrometer resolution in vivo and in real ...

      Smith & Nephew bets on technology that 'sees through the skin'

      Smith & Nephew has bet on a new technology that enables doctors to "see through the skin", in the hope that it could be used by the company's growing wound care business. The med tech giant has invested £1.25m in Michelson Diagnostics, a small Kent-based business which uses laser beams to produce high resolution images of cells beneath the surface of the skin. Michelson's Vivosight system is already being used in place of biopsies to diagnose non-melanoma skin cancer , a less aggressive but more common variety of the disease compared with more deadly melanoma skin cancers. But the ...
