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 Biomedical imaging is becoming an indispensable branch within bioengineering.

This research field has recently expanded due to the requirement of high-level medical diagnostics and rapid development of interdisciplinary modern technologies.

This book is designed to present the most recent advances in instrumentation, methods, and image processing as well as clinical applications in important areas of biomedical imaging. It provides broad coverage of the field of biomedical imaging, with particular attention to an engineering viewpoint.

Clinical Challenges

The goal of the book is to provide a wide-ranging forum in the biomedical imaging field that integrates interdisciplinary research and development of interest to scientists 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 It examines the use of electrochemical techniques in conservation science, with a particular focus on how to solve problems in taking on-site measurements.

Specifically, it introduces readers to a new gel polymer GPE electrochemical cell developed by the authors for the characterisation of metallic heritage objects. Other techniques used to characterise and monitor reinforced concrete objects in more modern buildings are also covered, including non-destructive electrochemical techniques that allow steel corrosion to be assessed 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. Optical coherence tomography OCT has enhanced our understanding and management of retinal diseases, ever since the time-domain OCT was introduced in the early s. The introduction of spectral-domain OCT in the mids and the later introduction of swept-source OCT provided faster scanning strategies and high-resolution images of the retina and choroid.

They were divided into 6 groups: controls, ocular hypertension, preperimetric glaucoma PPG , and three groups of 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. Julie A. Rodman, is a richly illustrated, practical guide to OCTA I am very proud and excited to introduce to you this book, which provides many interesting indications on how to better understand and handle the world of optical coherence tomography OCT. Reading the chapters, you will be aware that this device is extremely important not just in the clinical practice of retinal diseases, but is also very useful as a surgical tool.

Moreover, application of OCT has crossed the borders of the retina and is currently being applied to corneal diseases and glaucoma. I am confident you will find enough useful information to improve your practice using OCT and to This book focuses on the practical aspects of Optical Coherence Tomography OCT in glaucoma diagnostics offering important theoretical information along with many original cases.


OCT is a non-invasive imaging technique that acquires high-resolution images of the ocular structures. It enables clinicians to detect glaucoma in the early stages and efficiently monitor the disease. Optical Coherence Tomography in Glaucoma features updated information on technical applications of OCT in glaucoma, reviews recently published literature and provides clinical cases based on Cirrus and Spectralis OCT platforms. In addition, newer techniques like event and trend analyses for progression, macular ganglion cell analysis, and OCT 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.

It provides physicians with in-situ image data in micrometer resolution within seconds.

    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. Thus, invasive coronary imaging using intravascular ultrasound or optical coherence tomography can be useful to guide the PPCI procedure by locating the Master the Clinical Essentials of ocular and orbital anatomy for clinical practice!

    The eye is an organ of great complexity. Anatomy of the Eye and Orbit: The Clinical Essentials achieves the impressive task of presenting ophthalmology residents, optometry residents, and optometry students with the clinical essentials of ocular anatomy as a foundation for patient care. It emphasizes the aspects of eye and orbit anatomy that are most relevant to clinicians in training, providing the practical, real-world foundation necessary for practice.

    Focus on the clinically relevant information you really need to know about all ocular structures and tissues. View anatomy from Melanoma incidence has been increasing in the US population, with early detection and treatment leading to decreased morbidity and mortality.
