Book excerpt: Biomedical imaging is a vital part of preventative, diagnostic, and therapeutic medical treatment, but there are surprisingly few viable clinical tools at the microscale (1 to 100 microns; from a single to dozens of cells). Optical Coherence Tomography (OCT) is a high speed and portable 3D imaging technology poised to fill this gap. This work develops on two directions that expand the capabilities of OCT imaging and set up the groundwork for new clinical applications. The first is an investigation of gold nanoparticles as contrast agents in the second near-infrared imaging window. We demonstrate that injected gold nanoprisms are highly scattering contrast agents with tune-able scattering resonances which can be used to greatly enhance the sensitivity of OCT-based vascular imaging. Postinjection OCT angiograms reveal 41% and 59% more vasculature compared to control subjects in healthy and melanoma-bearing mouse skin respectively. We then demonstrate a spectral de-mixing model for gold nanoparticles, that allows us to resolve the proportions of up to 3 different gold nanobipyramids within each voxel. With this, we demonstrate the first instance of triplex OCT contrast agent imaging, used to visualize in vivo regional dynamics within a mouse lymphatic network. The second part of this work explores a new data-centric approach to interpreting optical medical images, a task that remains challenging for clinical professionals in spite of high imaging resolution. We have developed a laser-based barcoding technology that allows us to achieve ultra-high resolution registration (down to 25 microns) of OCT images with H&E pathology images. This technology has allowed us to assemble a library of hundreds of OCT-H&E images pairs from human skin samples obtained during Mohs surgery in a dermatology clinic. We then train a generative neural network on the image library and demonstrate the ability to virtually generate realistic H&E images directly from OCT images. This opens the door to an entirely virtual and non-invasive biopsy based on OCT imaging, bypassing the traditionally labor- and time- intensive biopsy procedure.

In chapter 5, case studies illustrate OCT imaging of the optic nerve, RNFL, and macula in all stages of glaucoma, from patients at risk to those with mild, moderate, and severe diseases. The next chapters cover the intrinsic relationship between optic nerve structure and function, the use of structure–function maps, and examples of their relationship, followed by a comparison of commonly used devices and a chapter on artifacts. Anterior segment OCT is covered next, followed by chapters covering special considerations in pediatric glaucomas and in patients with high refractive errors. The final chapters cover innovations in OCT on the horizon including OCT angiography, swept-source OCT, and artificial intelligence. Key Highlights Illustrative case examples provide firsthand clinical insights on how OCT can be leveraged to inform glaucoma treatment. In-depth guidance on recognizing and managing artifacts including case examples and key technical steps to help prevent their occurrence. Pearls on the use of OCT for less common patient scenarios such as pediatric glaucomas and high refractive errors.

Download or read book Handbook of Full-Field Optical Coherence Microscopy written by Arnaud Dubois and published by CRC Press. This book was released on 2016-10-14 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Full-field optical coherence microscopy (FF-OCM) is an imaging technique that provides cross-sectional views of the subsurface microstructure of semitransparent objects. The technology is based on low-coherence interference microscopy, which uses an area camera for en face imaging of the full-field illuminated object. FF-OCM benefits from the lateral imaging resolution of optical microscopy along with the capacity of optical axial sectioning at micrometer-scale resolution. The technique can be employed in diverse applications, in particular for non-invasive examination of biological tissues. This handbook is the first to be entirely devoted to FF-OCM. It is organized into four parts with a total of 21 chapters written by recognized experts and major contributors to the field. After a general introduction to FF-OCM, the fundamental characteristics of the technology are analyzed and discussed theoretically. The main technological developments of FF-OCM for improving the image acquisition speed and for endoscopic imaging are presented in part II. Extensions of FF-OCM for image contrast enhancement or functional imaging are reported in part III. The last part of the book provides an overview of possible applications of FF-OCM in medicine, biology, and materials science. A comprehensive compilation of self-contained chapters written by leading experts, this handbook is a definitive guide to the theoretical analyses, technological developments, and applications of FF-OCM. Using the rich information the book is replete with, a wide range of readers, from scientists and physicists to engineers as well as clinicians and biomedical researchers, can get a handle on the latest major advances in FF-OCM.
