  Explore IGI Global Jan 29 2019 Ophthalmology , Textbooks
  
  Optical coherence tomography (OCT) is a non-invasive imaging technique widely used in ophthalmology. The presence of speckle affects the quality of OCT images. Despeckling is necessary to improve its visual quality, and it is an integral part of software packages used for the computerized analysis of OCT. Even though a few methods for despeckling OCT are available in the literature, a cross-comparison of their performance is not known to be available. In this chapter, the techniques available in the literature for despeckling the OCT images have been identified. The results of the despeckling algorithms are compared both qualitatively and quantitatively ...

  New research in fingerprint biometrics uses optical coherence tomography (OCT) technology to acquire fingerprints from where they originate below the surface of the skin. The penetrative nature of this technology means that rich information is available regarding the structure of the skin. This access, in turn, enables new techniques in detecting spoofing attacks, and therefore also introduces mitigation steps against current presentation attack methods. These techniques include the ability to detect fake fingers; fake layers applied above the skin; differentiate between fakes and surface skin conditions; and liveness detection based on, among others, the analysis of eccrine glands and capillary ...

  Optical coherence tomography is a fast, non-invasive technique of structural analysis utilising near-infrared radiation. Examples of using OCT, for obtaining cross-sectional images of objects of craftsmanship and an easel painting have been shown. Issues regarding the technique of execution and destruction phenomena were resolved non-invasively. In some cases, the secondary alterations can be identified and localised within the object’s structure which helps in authentication of the artwork.

  Optical coherence tomography (OCT) has enhanced our understanding and management of retinal diseases, ever since the time-domain OCT was introduced in the early 2000s. The introduction of spectral-domain OCT in the mid-2000s and the later introduction of swept-source OCT provided faster scanning strategies and high-resolution images of the retina and choroid.

  Optical Coherence Tomography Angiography (OCTA) is a novel, non-invasive, dyeless imaging modality that has emerged as an indispensable tool in the fields of optometry and ophthalmology. OCTA provides three-dimensional volumetric images of the retinal and choroidal vasculature by using a motion-contrast decorrelation algorithm. This cutting-edge imaging technology has widespread clinical utility as a non-invasive alternative for visualizing microvasculature in detail, but there are no textbooks dedicated to its use and the interpretation of scans. To fill this need, Optical Coherence Tomography Angiography Atlas: A Case Study Approach , by Dr. Julie A. Rodman, is a richly illustrated, practical guide to OCTA ...

  Optical coherence tomography (OCT) is a noninvasive, high-resolution, interferometric imaging modality using near-infrared light to acquire cross sections and three-dimensional images of the subsurface microstructure of samples. Because of the rapid enhancement of OCT with respect to acquisition speed and axial resolution over the past years, OCT is becoming more and more attractive for applications in nondestructive testing and evaluation. In this chapter, a brief introduction to the technique and the instrumentation is first given, followed by an overview of application of OCT in NDE reported so far.

  OCT is an interferometry based three-dimensional imaging modality that can be used on scattering media, including several types of body tissues. It provides physicians with in-situ image data in micrometer resolution within seconds. OCT’s working principle is similar to ultrasound but uses light instead of sound waves and is also free of potentially harmful ionizing radiation while being non-invasive. OCT in ophthalmology (the branch of medicine concerned with the eyes) has been pioneered by David Huang, Eric Swanson, and James G. Fujimoto and has since become a standard modality and is widely used by clinicians on a daily basis ...

13. Role of Intravascular Imaging in Primary PCI (Book Chapter)
  
  Explore Home - Springer Jul 19 2018 Cardiology , Textbooks
  
  Primary percutaneous coronary intervention (PPCI) is always targeted on the angiographically identified culprit lesion. However, the actual culprit lesion may not compromise the lumen and can be located proximally or distally to the angiographic target lesion. As a result, the risk of incomplete lesion coverage can be high when the PPCI is guided solely by angiography. Furthermore, stent implantation must be optimized, as incomplete apposition and/or edge dissection may result in in-stent restenosis or acute thrombotic events. Thus, invasive coronary imaging using intravascular ultrasound or optical coherence tomography can be useful to guide the PPCI procedure by locating the ...

  Optical coherence tomography (OCT) is an imaging technique based on the detection of light back-reflected or backscattered by tissue. Based on the principles of low-coherence interferometry, OCT provides rapid volumetric imaging with micrometer-scale resolution. OCT has been massively successful in ophthalmology where it became a routine tool for retinal diagnostics. In recent years, however, OCT has also been applied to other fields including—amongst others—cardiovascular imaging, endoscopy of the gastrointestinal tract, and neuroimaging. In the brain and other neural tissues, OCT provides contrast for tissue microstructures and enables noninvasive in vivo and in vitro imaging with high resolution. Novel ...

  Stent thrombosis is a rare complication of percutaneous coronary intervention and carries a poor prognosis. Recent improvements in stent technology and new antiplatelet therapies have reduced the incidence of stent thrombosis. Coronary stent thrombosis has been defined by the Academic Research Consortium criteria. Four types of thrombosis are defined according to the time of occurrence from stent implantation: acute (<24 h), subacute (<30 days), late (between 1 month and 1 year), and very late (>1 year). Management consists primarily of urgent restoration of antegrade coronary flow. The concurrent management of platelet aggregation is of paramount importance; compliance with the regimen ...

  Ocular coherence tomography is being increasingly utilized to study disorders of the proximal lacrimal drainage system [1–5]. OCT can be useful for diagnosis and monitoring treatments for numerous conditions like the punctal stenosis, punctal agenesis, incomplete punctal canalization, punctal keratinizing cyst, and canaliculus. Typical FD-OCT features described for IPC include a hyper-reflective membrane covering the punctal surface with distinctly identifiable and normal lumen of the vertical canaliculus beneath. Membranotomy is the preferred modality of managing IPC with very high success rates where normal appearing wide punctum can be seen on OCT. Punctal stenosis is characterized by near total or ...

  Ocular coherence tomography is rapidly gaining foothold as an important imaging modality for the punctum and vertical canaliculus. It works on the principle of low coherence interferometry. The technique involves positioning the patient with their chin on the OCT chin rest and their forehead against the upper support. With the eyes open, the lower eyelid margin is gently everted using a cotton bud placed below the punctum just enough to get the punctum into a plane perpendicular to the light source. The long axis of scan is aligned approximately parallel to the lid margin, and line scan is captured. A ...
