Download or read book Orthogonal Polarization Spectral Imaging written by K. Messmer and published by Karger Medical and Scientific Publishers. This book was released on 2000-01-01 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces orthogonal polarized spectral (OPS) imaging, a new technique for examining the microcirculation in both animals and humans during surgery and in other clinical setups. OPS imaging creates an image by using the sub-surface scattering of polarized light to create a 'virtual' light source within the tissue being observed. Thus, the microcirculation can be visualized without the use of fluorescent dyes or transillumination, making it possible to observe the human microcirculation in real time. The technology has been incorporated into a small, hand-held device called a CYTOSCANTM video microscope, which can be used in both research and clinical settings. Several validation studies comparing OPS imaging against standard intravital fluorescence microscopy in animal models demonstrate that it is possible to make quantitative measurements of relevant parameters (vessel diameter, red blood cell velocity and functional capillary density) from these images. Further studies show the feasibility of making such measurements in various human organs such as the skin, intestine, and brain. In addition, this book presents several clinical applications including use in cardiopulmonary bypass, neurosurgery, intensive care, general surgery and plastic surgery. The book should be read by anyone concerned with microvascular perfusion. This includes not only those involved in microcirculation research but clinicians interested in nutritive perfusion. The technique described here will be of aid to a variety of surgical specialists from cardiac and neurosurgeons to plastic surgeons. It will likewise be of interest to angiologists, anesthesiologists, neonatologists, dermatologists, and general surgeons.

Download or read book Compressive Polar Spectral and Polarization Imaging written by Chen Fu and published by . This book was released on 2018 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional digital imaging captures the desired image information directly on an imaging sensor. When high dimensional imaging capability is required such as spectral imaging and spectropolarimetric imaging, inecient sampling strategies are usually involved, such as scanning and division of the focal plane array, resulting in either poor real-time imaging capability or sensor resolution reduction. Compressive sensing solves these problems via sampling of the high-dimensional image cubes below the Nyquist sampling rate, and recovering the image signal with sparsity constraints. In this dissertation, a newly proposed compressive spectral imaging and a compressive spectropolarimetric imaging system are described. In particular, a novel polar-shaped pixelated coding mask is proposed, optimized and implemented in spinning imaging systems. Multi-snapshots are achieved through the coding mask rotation. By combin- ing with a circular variable lter and a low-resolution monochrome sensor array, super- resolution in both spatial and spectral dimensions is attained. Both the geometry and the pattern of binary polar coded aperture are further optimized. A continuous imager rotation model is developed and simulated to resolve the rotation blur. Finally, the imaging system is tested with experimental measurements and reconstructions. On the other hand, a compressive spectropolarimetric imager is developed based on a micro- polarizer array, aiming at obtaining spectral linear Stokes images. Simulation shows a blue-noise pattern of micro-polarizer distribution highly improves the polarization reconstruction quality. A rotating double-amici prism further enables multi-snapshots. Reconstructions of spectral Stokes images as well as the degree and angle of polarization (DoP and AoP) images are then obtained from testbed experiments.
