  This disclosure relates to an OCT apparatus configured to generate to electromagnetic (e.g., optical) signals having two different polarization states. Two or more silicon optical amplifiers (SOAs) can be configured to maintain a respective polarization state in an optical input signal provided from a light source (e.g., a broadband light source). The different polarization states can be combined by an optical combiner (e.g., a polarization maintaining fiber ...

  Methods and apparatus automatically classify intravascular plaque using features extracted from intravascular optical coherence tomography (IVOCT) imagery. One example apparatus includes an image acquisition circuit that accesses a set of IVOCT images, a pre-processing circuit that generates a blood vessel mask based on the IVOCT images, a feature extraction circuit that defines a three dimensional (3D) volume of interest centered on a location in a member of the set of ...

4. Automated A-line coronary plaque classification of intravascular optical coherence tomography images using handcrafted features and large datasets
  
  Explore SPIE Digital Library Oct 9 2019 Cardiology
  
  We developed machine learning methods to identify fibrolipidic and fibrocalcific A-lines in intravascular optical coherence tomography (IVOCT) images using a comprehensive set of handcrafted features. We incorporated features developed in previous studies (e.g., optical attenuation and A-line peaks). In addition, we included vascular lumen morphology and three-dimensional (3-D) digital edge and texture features. Classification methods were developed using expansive datasets (7000images), consisting of both clinical in-vivo images and an ...

  Explore ScienceDirect Sep 14 2019 Ophthalmology
  
  A diagnostic sign refers to a quantifiable biological parameter that is measured and evaluated as an indicator of normal biological, pathogenic, or pharmacologic responses to a therapeutic intervention. When used in translational research discussions, the term itself often alludes to a signs used to accelerate or aid in diagnosis or monitoring and provide insight into personalized medicine. Many new diagnostic signs are being developed that involve imaging technology. Optical coherence ...

  Purpose: To describe spectral domain optical coherence tomography (SD-OCT) findings in an Amish cohort to assess SD-OCT markers for early age-related macular degeneration (AMD). Methods: The authors performed a family-based prospective cohort study of 1,146 elderly Amish subjects (age range 5099 years) (2,292 eyes) who had a family history of at least 1 individual with AMD. All subjects underwent complete ophthalmic examinations, SD-OCT using both Cirrus and Spectralis ...

9. The impact of blood pressure variability on coronary arterial lumen dimensions as assessed by optical coherence tomography in patients with ST-elevation myocardial infarction
  
  Explore ScienceDirect Jun 25 2019 Cardiology
  
  Background Patients with ST-elevation Myocardial Infarction treated by primary percutaneous coronary intervention (PPCI) experience drastic hemodynamic systemic changes (i.e., blood pressure) during the different phases of the procedure. Optical coherence tomography is often used to unveil the underlying cause of STEMI (pre-PCI) and to optimize stent implantation (post-PCI). The impact of blood pressure variability on coronary lumen remains uncertain. This study aimed to investigate the relationship between blood pressure ...

  $Diagnostic accuracy of intracoronary optical coherence tomography-derived fractional flow reserve for assessment of coronary stenosis severity$
  ims: A novel method for computation of fractional flow reserve (FFR) from optical coherence tomography (OCT) was developed recently. This study aimed to evaluate the diagnostic accuracy of a new OCT-based FFR (OFR) computational approach, using wire-based FFR as the reference standard. Methods and results: Patients who underwent both OCT and FFR prior to intervention were analysed. The lumen of the interrogated vessel and the ostia of the side branches ...

13. Title Automated Plaque Characterization of Intravascular Optical Coherence Tomography (IVOCT) Images Using 3D Cryo-image/Histology Validation (Thesis)
  
  Explore OhioLINK ETD Center May 28 2019 Cardiology , Student Theses
  
  Intravascular optical coherence tomography (IVOCT) is a high-resolution (10-20 m), high-contrast, catheter-based imaging technology that can identify major coronary plaques types (fibrous, lipid, and calcium). However, with 500 images generated in a single 2.5 second scan, automation is needed to facilitate live-time clinical use and off-line assessment of drug therapeutics. Therefore, we developed machine learning approaches for automated plaque characterization using cryo-imaging/histology for validation. However, we confronted a ...
