Download Clinical Applications Of Optical Coherence Tomography Angiography books, "The recent introduction of optical coherence tomography angiography (OCTA) has remarkably expanded our knowledge of different retinal, chorioretinal, and optic disc disorders. OCTA is nowadays often introduced as a routine exam in clinical practice, granting the opportunity to non-invasively investigate retinal and choroidal circulation. In this book, many major experts in posterior eye imaging share their experiences and their latest images and ideas about OCTA"--

Diagnostic And Therapeutic Devices And Applications Of Endoscopic Optical Coherence Tomography

by Osman Oguz Ahsen, Diagnostic And Therapeutic Devices And Applications Of Endoscopic Optical Coherence Tomography Books available in PDF, EPUB, Mobi Format. Download Diagnostic And Therapeutic Devices And Applications Of Endoscopic Optical Coherence Tomography books, There is an increased demand for developing transformative technologies to satisfy unmet needs in the clinical management of a number of gastrointestinal (GI) tract diseases. With the maturation of sweptsource lasers, OCT technology has undergone major advancements over the last few years. Swept‐source laser sources based on Fourier domain mode locking (FDML), akinetic and vertical cavity surface emitting laser (VCSEL) technologies have shown to reach and exceed MHz OCT imaging speeds. Our group has harnessed these advances by developing an ultrahigh‐speed endoscopic OCT system that operated at and above 600 kHz A‐scan rates, > 10 times faster than commercial endoscopic OCT systems. Equipped with distal rotating micromotor catheters, this system allowed visualization of microstructures and functional processes that were not possible to observe with the older generation OCT systems. The overarching aim of this thesis was to showcase novel clinical and research applications that were enabled by this next generation ultrahigh‐speed endoscopic OCT system. Towards this aim, this thesis focused on two main projects, 1) Demonstrating clinical applications of volumetric en face and crosssectional OCT, and OCT angiography (OCTA) and 2) Developing integrated OCT imaging and esophageal electrical muscle stimulation methods. For the first project, two gastrointestinal (GI) tact diseases were investigated: Barrett’s esophagus (BE) and associated dysplasia, and chronic radiation proctopathy (CRP). For the second project, esophageal electrical muscle stimulation methods were assessed to achieve circumferential esophageal tissue coverage for catheter imaging and therapeutic applications, with experiments performed in living swine. Furthermore, methods for improving scanning stability and robustness of the ultrahigh‐speed endoscopic OCT system, as well as for optimizing data acquisition and visualization were discussed. This thesis illustrated that ultrahigh‐speed endoscopic OCT technology powered by the next generation swept‐source light sources and precision scanning micromotor catheters opened new research directions ranging from diagnosis of early cancers to studying the pathophysiology of GI tract diseases and assessing efficacy of and response to therapeutic interventions. As the field of OCT continues to evolve, endoscopic OCT is one step closer to find its niche in solving prolonged clinical problems.

Optical Coherence Tomography Angiography Atlas

by Julie A. Rodman, Optical Coherence Tomography Angiography Atlas Books available in PDF, EPUB, Mobi Format. Download Optical Coherence Tomography Angiography Atlas books, 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. It provides detailed information on the fundamental principles behind the technology, as well as clinical applications critical for accurate interpretation. The first section of the book discusses the principles behind OCTA and provides an introduction into the interpretation of OCTA images, including a chapter devoted to terminology. The remainder of the book provides detailed analysis of a myriad of inner and outer retinal disorders, including diseases of the optic nerve head. Most importantly for the clinical setting, the cases are presented with numerous images and a multitude of arrows and callouts to assist in the recognition of various clinical findings. Case examples include: Vascular Occlusive Disease Pigment Epithelial Detachment Choroidal Neovascular Membrane Diabetic Retinopathy Optic Disc Edema Dr. Rodman's emphasis on the clinical use of OCTA technology and step-by-step interpretation of images makes Optical Coherence Tomography Angiography Atlas: A Case Study Approach a must-have resource for physicians, residents, students, and ophthalmic technicians looking for a simple, comprehensive guide to OCTA.

Structural And Functional Imaging Of The Human And Small Animal Eyes Using Ultrahigh Speed Fourier Domain Optical Coherence Tomography

Download Structural And Functional Imaging Of The Human And Small Animal Eyes Using Ultrahigh Speed Fourier Domain Optical Coherence Tomography books, Optical coherence tomography (OCT) is a non-invasive optical imaging technique that allows the three-dimensional structure of biological tissue to be visualized with micrometer resolution. In ophthalmology OCT has the unique advantage that it provides cross-sectional images of the retina and choroid noninvasively and in vivo, which have led OCT to be a clinical standard for the diagnosis of a variety of retinal diseases. Although current commercial Fourier domain OCT systems have high imaging speeds of 20-100kHz A-scan rates, these imaging speeds are not sufficient for more advanced structural and functional imaging techniques. Current state-of-the-art spectral domain and swept source OCT provide ultrahigh imaging speeds of >200kHz A-scan rates. These speeds enable functional imaging of retinal blood flow, OCT angiography of the retinal and choroidal microvasculature, and wide field volumetric structural imaging of the retina and choroid. In this thesis, advances in structural and functional ophthalmic imaging techniques for the human and small animal eyes are investigated using ultrahigh speed Fourier domain OCT. The following topics are discussed: (1) a method for numerically extracting and compensating dispersion mismatch in ultrahigh resolution spectral domain OCT, (2) ultrahigh speed spectral domain imaging in the small animal eye for measuring total retinal blood flow, (3) development of ultrahigh speed phase stable swept source OCT system for human retinal imaging, (4) OCT angiography of the choriocapillaris in the human eye, (5) clinical applications of OCT angiography in retinal diseases, including diabetic retinopathy and age-related macular degeneration, (6) small animal anesthesia protocol for functional hemodynamic imaging, and (7) imaging of neurovascular coupling in small animals using ultrahigh speed OCT.
