      Advances in Colposcopy (Book Chapter)

      Various new technologies have been introduced to improve the diagnostic accuracy of colposcopy, objectively guide to the site of biopsy, and measure the dysplastic nature of the epithelium. These include fluorescence spectroscopy, electrical impedance spectroscopy, diffuse reflectance spectroscopy, and/or their combinations. Other technologies like optical coherence tomography and polarimetric imaging have also been used to define the lesions better. Not only the adjunct use of technology but portable user-friendly devices have been developed which have increased the provision of colposcopy in remote areas.

    3. Swept-Source Optical Coherence Tomography and Optical Coherence Tomography Angiography in Selected Posterior Uveitides (Book Chapter)

      Swept-Source Optical Coherence Tomography and Optical Coherence Tomography Angiography in Selected Posterior Uveitides (Book Chapter)

      The pathogenesis of uveitis entails changes in the structural morphology of the macula, choroid, and choroidal perfusion. Documentation of these pathologic alterations is pivotal in making a proper diagnosis and in follow-up of outcomes of therapy. The newly-introduced swept-source optical coherence tomography (SS-OCT) and optical coherence tomography angiography (SS-OCTA) were harbingers of a whole new era of noninvasive in vivo layer-to-layer dissection of macular and choroidal structural changes in uveitis and of disease-related vascular profile patterns. This new information unraveled new aspects of the underlying pathogenetic mechanisms in different uveitides and added to our understanding of the disease process. Monitoring ...

    4. Despeckling Algorithms for Optical Coherence Tomography Images: A Review (Book Chapter)

      Despeckling Algorithms for Optical Coherence Tomography Images: A Review (Book Chapter)

      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 ...

    6. Optical Coherence Tomography for Fingerprint Presentation Attack Detection (Book Chapter)

      Optical Coherence Tomography for Fingerprint Presentation Attack Detection (Book Chapter)

      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 (OCT) for Examination of Artworks (Book Chapter)

      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 (Book Chapter)

      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 ...

    16. Role of Intravascular Imaging in Primary PCI (Book Chapter)

      Role of Intravascular Imaging in Primary PCI (Book Chapter)

      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 ...

      Multimodality Imaging to Detect Vulnerable Plaque in Coronary Arteries and Its Clinical Application (Book Chapter)

      Postmortem studies have described the association between the thin-cap fibroatheroma (TCFA) and the occurrence of acute coronary syndrome (ACS). Both noninvasive and invasive techniques have been refined and used as a research tool to visualize the plaque at a high risk of disruption. There has been a considerable effort to develop the imaging modalities that offer detailed visualization of coronary pathology and accurately predict the adverse cardiac outcomes. This chapter provides an overview of the current and experimental coronary imaging methods to detect vulnerable plaque and discuss the potential implication of multimodality imaging in clinical practice.

    20. Optical Coherence Tomography for Brain Imaging (Book Chapter)

      Optical Coherence Tomography for Brain Imaging (Book Chapter)

      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 ...

    23. Coronary Stent Thrombosis (Book Chapter)

      Coronary Stent Thrombosis (Book Chapter)

      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 ...
