Download or read book Optical Coherence Tomography in Cardiovascular Research written by Evelyn Regar and published by CRC Press. This book was released on 2007-03-06 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given that for centuries, the standard tool to understand diseases in tissues was the microscope and that its major limitation was that only excised tissue could be used, recent technology now permits the examination of diseased tissue in vivo. Optical coherence tomography (OCT) has promising potential when applied to coronary artery disease. OCT has the capability to identify coronary plaque and to distinguish between plaques that are stable and unstable. If the plaques are stable then OCT can direct percutaneous intervention (angioplasty or stenting). Optical coherence tomography is a light-based imaging technology that allows for very high resolution imaging in biological tissues. It has been first applied in ophthalmology, where it soon became the golden standard for the assessment of (epi-) retinal processes. The unique imaging capabilities have raised the interest of researchers and clinicians in the field of cardiovascular disease, since OCT offers unique possibilities to study atherosclerosis pathophysiology in vivo. With over 1.1M Americans having a heart attack this year because of unstable plaque rupture, OCT may have an increasingly important role in the early diagnosis of coronary artery disease. This unique publication offers the reader the basic background to OCT and its role in the diagnosis and management of coronary artery disease. The Handbook of Optical Coherence Tomography in Cardiovascular Research introduces the cardiovascular application of this technology. Clinicians, biologists, engineers and physicist are discussing different aspects of cardiovascular OCT application in a multidisciplinary approach. The handbook offers the readership a concise overview on the current state of the art of vascular OCT imaging and sheds light on a variety of exciting new developments. The physics, technical principles of OCT and its application in a broad spectrum of cardiovascular research areas are summarized by highly recognized specialists. The potential of OCT in peripheral and coronary arteries and in developmental cardiology are described. Each research area is introduced by a clinical expert in the field followed by discussion of different aspects from an engineering, biomedical and clinical perspective. Specifically, the current capabilities for plaque characterization, detection of vulnerable plaque, guidance of interventional procedures, Doppler-assessment, and molecular contrast imaging are being described. The Handbook of Optical Coherence Tomography in Cardiovascular Research targets researchers and clinicians involved in the field of atherosclerosis. The summary of basic physics, engineering solutions, pre-clinical and clinical application covers all relevant aspects and will be a valuable reference source.

Download or read book Intravascular Optical Coherence Tomography Image Analysis written by Zhao Wang and published by . This book was released on 2013 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coronary artery disease (CAD) is the leading cause of death in the world. Most acute coronary events such as heart attacks and sudden deaths are due to the rupture of atherosclerotic plaques inside the arteries. Intravascular Optical Coherence Tomography (IVOCT), a high resolution (10-20μm) imaging modality that performs cross-sectional imaging of coronary arteries by measuring echoes of backscattered light, is rapidly becoming a promising imaging modality for diagnosis of CAD. Compared to alternative technologies such as intravascular ultrasound (IVUS), IVOCT with better resolution allows characterization of atherosclerotic plaques and evaluation of coronary stenting with unprecendented details. Currently, analysis of OCT images has been typically conducted manually in an extremely time-consuming manner. The aim of this PhD dissertation is to develop advanced image processing algorithms and software to automate the task and thereby reduce the image analysis time drastically. In this dissertation, we developed image analysis algorithms for a variety of IVOCT applications, including: (1) 3-D lumen boundary segmentation, (2) Guide wire artifact segmentation, (3) Automated calibration of IVOCT images, (4) Volumetric quantification of fibrous caps, (5) Automated segmentation of calcified plaques, (6) Automated quantification of macrophages and (7) Automated stent analysis, covering almost all the essential tasks performed in the Cardiovascular Imaging Core Laboratories (Core Lab). The algorithms we have developed have been extensively validated using a large number of data sets, and are robust to be used for real world clinical data analysis. Furthermore, we developed the prototype software OCTivat (intravascular OCT image visualization and analysis toolkit) for IVOCT image visualization and analysis, and it is being used by the interventional cardiologists in the Core Lab at the University Hospitals Case Medical Center. These image analysis methods, as well as OCTivat, can reduce the IVOCT image analysis time from tens of hours down to minutes. This may enable large clinical trial analysis and real-time feedback during clinical procedures, and may potentially improve patient care.

K. Saboowala and published by Dr.Hakim Saboowala. This book was released on 2022-03-24 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Need to know about Optical Coherence Tomography (OCT): A Novel, Promising Imaging Modality, for examining Coronary arteries having 10-fold higher resolution than IVUS. In cardiology, OCT is an optical analog of for IVUS examination is replaced intravascular ultrasound (IVUS), used to examine the coronary arteries. Ultrasound employed by near-infrared light with a wavelength of about 1,300 nm, which is absorbed by red blood cells, water, lipids, and protein at relatively low levels. Through a rotating glass fiber-optic system, coherent infrared light can be directed and reflected within the tissue to create a detailed tissue image with extraordinarily high resolution, and IVUS-like cross-sectional tomographic images can be obtained. OCT and IVUS differ in several respects. The resolution of OCT (to 10-20 µm) is about 10-fold higher than that of IVUS (to 100-150 µm), but the maximum depth of tissue penetration is lower with OCT (1-2 mm) than with IVUS (4-8 mm). Another important difference is related to the strong attenuation of light by blood, which originates from two sources: absorption by: · haemoglobin and · scattering by red blood cells. To examine coronary arteries, blood must first be removed during an OCT examination to eliminate massive scattering of light by red blood cells. Thus, an attempt has been made to discuss the role of OTC in Cardiology along with several relevant Tables and Illustrations for better understanding! …Dr. H. K. Saboowala. M.B.(Bom) .M.R.S.H.(London
