Book Description
This fourth volume of Light Scattering Reviews is composed of three parts. The ?rstpartisconcernedwiththeoreticalandexperimentalstudiesofsinglelightsc- tering by small nonspherical particles. Light scattering by small particles such as, for instance, droplets in the terrestrial clouds is a well understood area of physical optics. On the other hand, exact theoretical calculations of light scattering p- terns for most of nonspherical and irregularly shaped particles can be performed only for the restricted values of the size parameter, which is proportional to the ratio of the characteristic size of the particle to the wavelength?. For the large nonspherical particles, approximations are used (e. g. , ray optics). The exact th- retical techniques such as the T-matrix method cannot be used for extremely large particles, such as those in ice clouds, because then the size parameter in the v- iblex=2?a/???,wherea is the characteristic size (radius for spheres), and the associated numerical codes become unstable and produce wrong answers. Yet another problem is due to the fact that particles in many turbid media (e. g. , dust clouds) cannot be characterized by a single shape. Often, refractive indices also vary. Because of problems with theoretical calculations, experimental (i. e. , la- ratory) investigations are important for the characterization and understanding of the optical properties of such types of particles. The ?rst paper in this volume, written by B. Gustafson, is aimed at the descr- tionofscaledanalogueexperimentsinelectromagneticscattering.

Book Description
Introduction to Biological Imaging Discover what biological imaging is able to accomplish in this up-to-date textbook One of the fundamental goals of biology is to understand how living organisms establish and maintain their spatiotemporal organization of the biochemical, cell biological and developmental biology processes that sustain life. Biological systems are inherently complex with a large number of components needed to sustain cellular function. In order to understand any complex system, one must determine its composition by identifying the components it is made of, how each of these components function and carry out their specific task, and how they interact with one another to function together. To grasp the link of such changes to physiological cell and tissue function and/or pathogenesis/disease progression, we need to understand how modifications alter macromolecular function, macromolecular interactions, and/or spatiotemporal distribution and overall supramolecular structural organization. Biological imaging holds the key to understanding spatiotemporal organization, and will thus be increasingly important for the next generations of biological and biochemical researchers. Introduction to Biological Imaging provides the first comprehensive textbook surveying this subject. It elucidates the fundamental principles underlying the capture and production of bioimages, the requirements of image analysis and interpretation, and some key problems and solutions in bioimaging. It includes everything experimental biologists need to incorporate appropriate bioimaging solutions into their work. Introduction to Biological Imaging readers will also find: Coverage of all major types of biological imaging, including medical imaging, cellular imaging, macromolecular imaging, and more Advice on preparing samples for various imaging methods Specific examples in each chapter connecting bioimaging process to the production of real experimental data Introduction to Biological Imaging is a valuable introduction for undergraduate or graduate students in courses relating to bioimaging, as well as scientists and researchers in the biological and medical fields who want a one-stop reference for the full range of imaging techniques.

Book Description
This book describes the Optical Immersion Clearing method and its application to acquire information with importance for clinical practice and various fields of biomedical engineering. The method has proved to be a reliable means of increasing tissue transparency, allowing the investigator or surgeon to reach deeper tissue layers for improved imaging and laser surgery. This result is obtained by partial replacement of tissue water with an active optical clearing agent (OCA) that has a higher refractive index and is a better match for the refractive index of other tissue components. Natural tissue scattering is thereby reduced. An exponential increase in research using this method has occurred in recent years, and new applications have emerged, both in clinical practice and in some areas of biomedical engineering. Recent research has revealed that treating ex vivo tissues with solutions containing active OCAs in different concentrations produces experimental data to characterize drug delivery or to discriminate between normal and pathological tissues. The obtained drug diffusion properties are of interest for the pharmaceutical and organ preservation industry. Similar data can be estimated with particular interest for food preservation. The free water content evaluation is also of great interest since it facilitates the characterization of tissues to discriminate pathologies. An interesting new application that is presented in the book regards the creation of two optical windows in the ultraviolet spectral range through the application of the immersion method. These induced transparency windows open the possibility to diagnose and treat pathologies with ultraviolet light. This book presents photographs from the tissues we have studied and figures that represent the experimental setups used. Graphs and tables are also included to show the numerical results obtained in the sequential calculations performed.

Book Description
This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.
