Download or read book Biomedical Imaging Using Fiber Optics written by Andy Yen Hsin Chen and published by LAP Lambert Academic Publishing. This book was released on 2012-06 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book 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. A prototype all-fiber OCT system was subsequently constructed to meet the design requirements of combined fluorescence-OCT probes. A novel spectroscopic technique that can monitor bacterial species in-situ was developed. Its capabilities and limitations were demonstrated through a series of laboratory controlled experiments which showed promising preliminary results. A fluorescence setup was developed to make spectroscopic measurement of cardiac action potentials. This technique offered more insights into the complex process of spectral modulation which is usually associated with membrane potential and mechanical activity.

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.
Download or read book Biomedical Optical Imaging written by James G. Fujimoto and published by Oxford University Press. This book was released on 2009-04-22 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomedical optical imaging is a rapidly emerging research area with widespread fundamental research and clinical applications. This book gives an overview of biomedical optical imaging with contributions from leading international research groups who have pioneered many of these techniques and applications. A unique research field spanning the microscopic to the macroscopic, biomedical optical imaging allows both structural and functional imaging. Techniques such as confocal and multiphoton microscopy provide cellular level resolution imaging in biological systems. The integration of this technology with exogenous chromophores can selectively enhance contrast for molecular targets as well as supply functional information on processes such as nerve transduction. Novel techniques integrate microscopy with state-of-the-art optics technology, and these include spectral imaging, two photon fluorescence correlation, nonlinear nanoscopy; optical coherence tomography techniques allow functional, dynamic, nanoscale, and cross-sectional visualization. Moving to the macroscopic scale, spectroscopic assessment and imaging methods such as fluorescence and light scattering can provide diagnostics of tissue pathology including neoplastic changes. Techniques using light diffusion and photon migration are a means to explore processes which occur deep inside biological tissues and organs. The integration of these techniques with exogenous probes enables molecular specific sensitivity.
