    2. Characterizing Ablation Lesions Using Optical Coherence Tomography (OCT)

      Characterizing Ablation Lesions Using Optical Coherence Tomography (OCT)
      Systems, methods, and other embodiments associated with characterizing Radio Frequency Ablation (RFA) lesions using Optical Coherence Tomography (OCT) are described. One example method includes acquiring an OCT signal from a Region Of Interest (ROI) in an ablated material. The example method may also include determining whether a lesion was formed by the ablation by analyzing optical properties of the ROI as recorded in the OCT signal.

    4. Mapping conduction velocity of early embryonic hearts with a robust fitting algorithm

      Mapping conduction velocity of early embryonic hearts with a robust fitting algorithm
      Cardiac conduction maturation is an important and integral component of heart development. Optical mapping with voltage-sensitive dyes allows sensitive measurements of electrophysiological signals over the entire heart. However, accurate measurements of conduction velocity during early cardiac development is typically hindered by low signal-to-noise ratio (SNR) measurements of action potentials. Here, we present a novel image processing approach based on least squares optimizations, which enables high-resolution, low-noise conduction velocity mapping of ...

    6. Investigating Hemodynamics of the Developing Embryonic Heart using Optical Coherence Tomography (Thesis)

      Investigating Hemodynamics of the Developing Embryonic Heart using Optical Coherence Tomography (Thesis)
      Blood flow is a critical factor that regulates developmental programs during cardiogenesis. During early embryonic development, deviations from the normal blood flow pattern have been shown to lead to congenital heart defects including septal defects and outflow tract anomalies. To better understand the role flow and the resulting hemodynamic forces play during cardiovascular development precise tools are needed to rapidly calculate and monitor these forces. Optical coherence tomography (OCT) is ...

    7. A Honeycomb-Like Structure in Chronic Total Occlusion Demonstrated by Frequency-Domain Optical Coherence Tomography

      A Honeycomb-Like Structure in Chronic Total Occlusion Demonstrated by Frequency-Domain Optical Coherence Tomography
      A 68 year-old male with a history of hypertension and current smoking was admitted due to exertional chest pain. Coronary angiography (CAG) showed a chronic total occlusion (CTO) in the left circumflex artery with collateral supply from the right coronary artery (Fig. 1). PCI was performed in this lesion as patient has normal left ventricular function. After crossing the lesion with guide wire (Gaia 2nd) and micro catheter, frequency-domain optical ...

    8. 3-D Stent Detection in Intravascular OCT Using a Bayesian Network and Graph Search

      3-D Stent Detection in Intravascular OCT Using a Bayesian Network and Graph Search
      Worldwide, many hundreds of thousands of stents are implanted each year to revascularize occlusions in coronary arteries. Intravascular optical coherence tomography (OCT) is an important emerging imaging technique, which has the resolution and contrast necessary to quantitatively analyze stent deployment and tissue coverage following stent implantation. Automation is needed, as current, it takes up to 16 hours to manually analyze hundreds of images and thousands of stent struts from a ...

    9. Image-guided modified deep anterior lamellar keratoplasty (DALK) corneal transplant using intraoperative optical coherence tomography

      Image-guided modified deep anterior lamellar keratoplasty (DALK) corneal transplant using intraoperative optical coherence tomography
      Deep anterior lamellar keratoplasty (DALK) is an alternative to full-thickness corneal transplant and has advantages including the absence of allograft rejection; shortened duration of topical corticosteroid treatment and reduced associated risk of glaucoma, cataract, or infection; and enables use of grafts with poor endothelial quality. DALK begins by performing a trephination of approximately 80% stromal thickness, as measured by pachymetry. After removal of the anterior stoma, a needle is inserted ...

    10. Intraoperative optical coherence tomography using an optimized reflective optical relay, real-time heads-up display, and semitransparent surgical instrumentation

      Intraoperative optical coherence tomography using an optimized reflective optical relay, real-time heads-up display, and semitransparent surgical instrumentation
      Ophthalmic surgical maneuvers are currently limited by the ability of surgeons to visualize and manipulate semitransparent tissue layers as thin as tens of microns. We describe several iterative advances in iOCT technology, including a novel iOCT system, real-time heads-up display (HUD) feedback, visualization of intraoperative maneuvers, and OCT-compatible surgical instrumentation. Simulated surgical maneuvers were performed on freshly enucleated porcine eyes. Subretinal space cannulation with injection was performed and imaged using ...

      Ethnic Differences in Trabecular Meshwork Height by Optical Coherence Tomography
      Importance Differences in ocular anatomy may contribute to ethnic differences in glaucoma risk. Because the trabecular meshwork (TM) plays an important role in aqueous outflow, its anatomy in relation to at-risk populations may provide insight into a potential contributor to elevated intraocular pressure and thus to probability of glaucoma development. Objective To investigate whether differences exist in TM height between ethnic groups. Design, Setting, and Participants This prospective study took ...
