This book was released on 2011 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis focuses on the instrumentation aspect of biomedical imaging with the use of optical fiber probes across three different disciplines. This includes the design and development of novel fiber optic based techniques and instruments in fields of optical coherence tomography (OCT), bioremediation and optical mapping of cardiac action potentials. Although the mechanism behind the imaging techniques of fluorescence and OCT are fundamentally different, the fact that both techniques permit the use of fiber probes gives rise to the possibility of a combined fluorescence-OCT probe. For example, the OCT and fluorescence portions of the integrated system are optically distinct, except for the final optics of the fluorescence-OCT fiber probe. Analog processing electronics for the subsystems can also be distinct, but for the purpose of synchronization and simultaneous data acquisition, both should be controlled by a central computer. Tumlinson and co-workers [140] have already demonstrated the development of such a system for simultaneous optical coherence tomography and laser-induced fluorescence measurement. We begin by demonstrating the feasibility of using the novel source, supercontinuum, in an OCT system. Its capabilities and limitations are also discussed. A prototype all-fiber OCT system was subsequently constructed to meet the design requirements of combined fluorescence-OCT probes. Current bioremediation methods are hindered by the lack of reliable, non-destructive, and in situ monitoring techniques. We investigate the feasibility of developing a novel spectroscopic technique that can monitor bacterial species in situ. A fluorescence spectroscopy system that meets the design criteria is subsequently built. Its capabilities and limitations were demonstrated through a series of laboratory controlled experiments which showed promising preliminary results. Optical mapping of cardiac action potential have proved to be indispensable in the study of arrhythmia. Although optical recordings using optical fibers have already been demonstrated with convincing results, none of which were spectrally resolved. We have constructed a fluorescence setup to make spectroscopic measurement of cardiac action potentials. This has offered more insights into the complex process of spectral modulation which is usually associated with membrane potential and mechanical activity.

Book excerpt: Pressing ethical issues are at the foreground of newfound knowledge of how the brain works, how the brain fails, and how information about its functions and failures are addressed, recorded and shared. In Neuroethics: Anticipating the Future, a distinguished group of contributors tackle current critical questions and anticipate the issues on the horizon. What new balances should be struck between diagnosis and prediction, or invasive and non-invasive interventions, given the rapid advances in neuroscience? Are new criteria needed for the clinical definition of death for those eligible for organ donation? What educational, social and medical opportunities will new neuroscience discoveries bring to the children of tomorrow? As data from emerging technologies are made available on public databases, what frameworks will maximize benefits while ensuring privacy of health information? How is the environment shaping humans, and humans shaping the environment? These challenging questions and other future-looking neuroethical concerns are discussed in depth. Written by eminent scholars from diverse disciplines - neurology and neuroscience, ethics, law, public health, and philosophy - this new volume on neuroethics sets out the conditions for active consideration. It is essential reading for the fields of neuroethics, neurosciences and psychology, and an invaluable resource for physicians in neurology and neurosurgery, psychiatry, paediatrics, and rehabilitation medicine, academics in humanities and law, and health policy makers.
Download or read book Near infrared Speckle Contrast Diffuse Correlation Tomography for Noncontact Imaging of Tissue Blood Flow Distribution written by Daniel Irwin and published by CRC Press. This book was released on 2022-11-07 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Imaging of tissue blood flow (BF) distributions provides vital information for the diagnosis and therapeutic monitoring of various vascular diseases. The innovative near-infrared speckle contrast diffuse correlation tomography (scDCT) technique produces full 3D BF distributions. Many advanced features are provided over competing technologies including high sampling density, fast data acquisition, noninvasiveness, noncontact, affordability, portability, and translatability across varied subject sizes. The basic principle, instrumentation, and data analysis algorithms are presented in detail. The extensive applications are summarized such as imaging of cerebral BF (CBF) in mice, rat, and piglet animals with skull penetration into deep brain. Clinical human testing results are described by recovery of BF distributions on preterm infants (CBF) through incubator wall, and on sensitive burn tissues and mastectomy skin flaps without direct device-tissue interactions. Supporting activities outlined include integrated capability for acquiring surface curvature information, rapid 2D blood flow mapping, and optimizations via tissue-like phantoms and computer simulations. These applications and activities both highlight and guide the reader as to the expected abilities and limitations of scDCT for adapting into their own preclinical/clinical research, use in constrained environments (i.e., neonatal intensive care unit bedside), and use on vulnerable subjects and measurement sites.
