Superresolution Optical Microscopy: The Quest for Enhanced Resolution and Contrast

為了解決contrast enhancement的問題，作者Masters, Barry R. 這樣論述：

This book presents a comprehensive and coherent summary of techniques for enhancing the resolution and image contrast provided by far-field optical microscopes. It takes a critical look at the body of knowledge that comprises optical microscopy, compares and contrasts the various instruments, provid

es a clear discussion of the physical principles that underpin these techniques, and describes advances in science and medicine for which superresolution microscopes are required and are making major contributions. The text fills significant gaps that exist in other works on superresolution imaging,

firstly by placing a new emphasis on the specimen, a critical component of the microscope setup, giving equal importance to the enhancement of both resolution and contrast. Secondly, it covers several topics not typically discussed in depth, such as Bessel and Airy beams, the physics of the spiral

phase plate, vortex beams and singular optics, photoactivated localization microscopy (PALM), stochastic optical reconstruction microscopy (STORM), structured illumination microscopy (SIM), and light-sheet fluorescence microscopy (LSFM). Several variants of these techniques are critically discussed.

Noise, optical aberrations, specimen damage, and artifacts in microscopy are also covered. The importance of validation of superresolution images with electron microscopy is stressed. Additionally, the book includes translations and discussion of seminal papers by Abbe and Helmholtz that proved to

be pedagogically relevant as well as historically significant. This book is written for students, researchers, and engineers in the life sciences, medicine, biological engineering, and materials science who plan to work with or already are working with superresolution light microscopes. The volume c

an serve as a reference for these areas while a selected set of individual chapters can be used as a textbook for a one-semester undergraduate or first-year graduate course on superresolution microscopy. Moreover, the text provides a captivating account of curiosity, skepticism, risk-taking, innovat

ion, and creativity in science and technology. Good scientific practice is emphasized throughout, and the author's lecture slides on responsible conduct of research are included as an online resource which will be of interest to students, course instructors, and scientists alike. Professor Barry R

. Masters received a PhD from The Weizmann Institute of Science, Israel, an MS degree from Florida State University, and a BS from The Polytechnic Institute of Brooklyn, New York. Professor Masters was Visiting Scientist in the Department of Biological Engineering at the Massachusetts Institute of T

echnology, Visiting Scholar in the History of Science Department at Harvard University, Visiting Professor in the Department of Ophthalmology at the University of Bern, and Professor in Anatomy and Cell Biology at the Uniformed Services University of the Health Sciences. He was a Visiting Professor

in Japan, India, Australia, Switzerland, Taiwan, Turkey, The United Kingdom, P. R. China, and Egypt. He is a Fellow of the American Association for the Advancement of Science (AAAS), the Optical Society of America (OSA), and the international society for optics and photonics (SPIE). From 1999 to 200

0, Professor Masters was an AAAS Congressional Science and Engineering Fellow and served as Legislative Assistant in the United States Congress. He is a recipient of the Vogt Prize for Ophthalmic Research (highest Swiss award for research in ophthalmology) with Dr. Matthias Böhnke in 1999 for their

work on ＂confocal microscopy of the cornea.＂ Professor Masters has published 87 refereed papers, 143 book chapters and proceedings articles, 105 abstracts, and 239 book reviews. He is the editor or author of 10 books, among them Noninvasive Diagnostic Techniques in Ophthalmology, Confocal Microscopy

and Multiphoton Excitation Microscopy: The Genesis of Live Cell Imaging, and Handbook of Biomedical Nonlinear Optical Microscopy (with Peter So). Masters wrote the essay ＂What Is Light?＂ (translated into 15 languages) for the International Commission for Optics (ICO), to inaugurate the Internationa

l Year of Light, 2015. He lectures worldwide on the Responsible Conduct of Research, biomedical ethics, critical thinking, and biomedical photonics. His scholarly interests include developments in the fields of in vivo microscopy of the human eye and skin, biomedical imaging and spectroscopy, fracta

l analysis of branching vascular patterns, ethics in science and medicine, the history of nineteenth- and twentieth-century physics, science education, and art and science.

用於雄激素性脫髮評估之自動毛髮密度估計算法開發

為了解決contrast enhancement的問題，作者楊晨 這樣論述：

在臨床上，脫髮會反映在毛髮密度的狀態，醫生根據毛髮密度來評估脫髮的程度，以便為患者提供更好的治療。隨著影像和電腦技術的發展，已經出現了多種軟體工具用於帮助醫生評估毛髮密度，例如Trichoscan 和 Trichoscope with Folliscope。然而，它們分析前還需要修剪染髮或人工標記的前置步驟，這會造成使用上的不便。在這項研究中，提出了一種自動毛髮密度估計演算法來評估毛髮密度資訊並評估雄激素性脫髮的嚴重程度。在此，頭皮照片是由市售顯微鏡拍攝的。經過對比度增強的預處理，該演算法可以自動從頭皮照片中提取四種毛髮密度參數。最後，利用神經網路技術及提取的毛髮密度資訊對雄激素性脫髮組和健

康組進行人工智慧的分類。實驗結果表明，所提出的系統可以自動提取毛髮密度資訊，並有效地對雄激素性脫髮組和健康組進行分類。
