This book was released on 2011 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the results of the creation of methods for ophthalmologists support in OCT images automated analysis. These methods, like the application developed on their basis, are used during routine examinations carried out in hospital. The monograph comprises proposals of new and also of known algorithms, modified by authors, for image analysis and processing, presented on the basis of example of Matlab environment with Image Processing tools. The results are not only obtained fully automatically, but also repeatable, providing doctors with quantitative information on the degree of pathology occurring in the patient. In this case the anterior and posterior eye segment is analysed, e.g. the measurement of the filtration angle or individual layers thickness. To introduce the Readers to subtleties related to the implementation of selected fragments of algorithms, the notation of some of them in the Matlab environment has been given. The presented source code is shown only in the form of example of implementable selected algorithm. In no way we impose here the method of resolution on the Reader and we only provide the confirmation of a possibility of its practical implementation.

This book was released on 2018 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vision loss, with a prevalence loss greater than 42 million in the United States is one of the major challenges of today's health-care industry and medical science. Early detection of different retinal-related diseases will dramatically reduce the risk of vision loss. Optical Coherence Tomography (OCT) is a relatively new imaging technique which is of great importance in the identification of ocular and especially retinal diseases. Thus, the efficient analysis of OCT images provides several advantages. In this thesis, we propose a series of image processing and machine learning techniques for the automated analysis of OCT images. The proposed methodology in chapter 2 localizes different retinal layers using a modified version of active contour models. In chapter 3, we propose a method which classifies OCT images based on different pathological conditions using novel methods, e.g., transfer learning and new texture detection techniques. The proposed methods along with the clinically meaningful extracted characteristics provide numbers of applications and benefits, e.g., saving a considerable amount of time and providing more-efficient and -accurate indices for the diagnosis and treatment of different ocular diseases to ophthalmologists and finally reducing the overall risk of vision loss.

Available in PDF, EPUB and Kindle. Book excerpt: Optical coherence tomography (OCT) is the optical analog of ultrasound imaging and is a powerful imaging technique that enables non-invasive, in vivo, high resolution, cross-sectional imaging in biological tissue. Between 30 to 40 Million OCT imaging procedures are performed per year in ophthalmology. The overall market is estimated at more than 0.5 Billion USD. A new generation OCT technology was developed, dramatically increasing resolution and speed, achieving in vivo optical biopsy, i.e. the visualization of tissue architectural morphology in situ and in real time. Functional extensions of OCT technology enable non-invasive, depth resolved functional assessment and imaging of tissue. The book introduces OCT technology and applications not only from an optical and technological viewpoint, but also from the biomedical and clinical perspective. This second edition is widely extended and covers significantly more topics then the first edition of this book. The chapters are written by leading international research groups, in a style comprehensible to a broad audience. It will be of interest not only to physicists, scientists and engineers, but also to biomedical and clinical researchers from different medical specialties.

This book was released on 2006 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Central comeal thickness (CCT) is important in the diagnosis and management of glaucoma, in the management of refractive surgery patients and in the management of diseases such as keratoconus and Fuch's endothelial dystrophy. With the increase in the number of extended wear contact lens patients, corneal thickness is useful in monitoring the amount of edema that occurs with this lens modality. CCT can be measured using different techniques, the most common being optical and ultrasonic. Ultrasonic pachymetry is the clinical gold standard. Presently, there are many instruments on the market that employ optical techniques in a variety of ways, such as interferometry and they can be used in the measurement of CCT. Before these instruments can be reliably used, it is important to determine the repeatability of the instruments for measuring central corneal thickness on the eyes of normal subjects. The purpose of this study was to determine the within and between session repeatability of the Orbscan topographical system, the optical coherence tomography system (OCT) device, the confocal microscope, the spectral oscillation interferometry (SOl) system and the ultrasonic pachymeter. Twenty subjects (11 males and 9 females) were enrolled in the study after performing a slit lamp exam to rule out any ocular pathology. The mean age and SD of the subjects were 26.7 ± 6.0 years. The CCT was determined on the right eyes of twenty normal subjects using the five instruments stated above. The order of testing was randomized for the OCT device, SOT system, Orbscan system and confocal microscope, and the ultrasonic pachymeter was the last instrument to be used on all occasions. At the first session, two thickness measurements were found with the OCT device, confocal microscope and Orbscan system. Ten measurements were made with the SOI system, and five measurements were made with the ultrasonic pachymeter. The second session was performed within four months of the first session about the same time of day as the first session. The intra-ocular pressures of the right eyes were determined at the end of each session. Statistical analyses were performed to determine the within and between session repeatability of the five instruments. The bias and 95% limits of agreement (L0A) based on the Bland and Altman method were calculated for within session repeatability of the OCT device, confocal microscope and the Orbscan device. The coefficient of repeatability (CoR) was calculated for within session repeatability of the SOI and ultrasound methods. The bias and 95% LoA were calculated for the between session repeatability of all the instruments. Finally, ultrasonic pachyrnetry was compared with each of the other instruments using a repeated measures of analysis of variance to compare the methods while adjusting for the correlation that exists between observations collected on the same subject. The mean CCT averaged over session for each subject was 532.92 + 38.12 um for the ultrasound pachymeter, 519.30 ± 35.32 um for the OCT device, 555.68 ± 48.26 um for the Orbscan system, 546.02 ± 37.23 um for the confocal microscope and 512.54 ± 34.18 um for the SOI system. overall CoR of 1.90. The ultrasonic pachymeter showed a CoR of 7.70 for a mean CCT 525 urn, aCoRof 15.62 forameanCCT 525 umatsession I and, aCoRof8.86 fora mean CCT of
