Book Description
Instrumentation with clinical implications for imaging the human oculus was developed, based upon the hyperspectral imaging modality. The novel, non invasive, microscopic multi-modal hyperspectral imaging system, which operates in the visible as well as near infrared region, is capable of generating images illustrating spatial distribution of oxyhemoglobin contributions. The device principally comprises of a liquid crystal tunable filter and a focal plane array detector that is integrated to the slit lamp microscope. A proof of principle clinical study involving ten healthy subjects was undertaken to image the microvascular structure within the dermal tissue within the near infrared region, however these results are not validated. The spectral range used in the study was 650--1050nm, with a spectral resolution of 5nm, magnification of 10X to obtain a 35 ms acquisition time and a spatial resolution of 0.054 mm at binning of 1 x 1. The successful dermal microvascular study paved way for imaging the human eye using the visible region, wherein the anterior scleral surface was visualized in seven healthy subjects to spatially map the oxyhemoglobin contributions in the microvasculature perfusing the sclera. The spectral range used in the human eye study was 520--602nm, with a spectral resolution of 2nm, magnification of 10X to obtain a 5 ms acquisition time and a spatial resolution of 0.038 mm at binning of 2 x 2.

Book Description
Techniques and Applications of Hyperspectral Image Analysis gives an introduction to the field of image analysis using hyperspectral techniques, and includes definitions and instrument descriptions. Other imaging topics that are covered are segmentation, regression and classification. The book discusses how high quality images of large data files can be structured and archived. Imaging techniques also demand accurate calibration, and are covered in sections about multivariate calibration techniques. The book explains the most important instruments for hyperspectral imaging in more technical detail. A number of applications from medical and chemical imaging are presented and there is an emphasis on data analysis including modeling, data visualization, model testing and statistical interpretation.

Book Description
This book is a guide to biomedical visualization in microscopy, a new method of computer-aided three-dimensional imaging. Aspects of computer graphics, image analysis, specimen preparation, and microscopy technology are combined in this multiauthored work to provide thorough coverage of the most important biomedical applications of visualization. Examples include three-dimensional imaging of serial mechanical sections in light and electron microscopy as well as non-invasive sections in microtomography and confocal microscopy. Special emphasis is placed on advanced 3-D imaging with laser scanning microscopes. An exciting new technique presented here is four-dimensional visualization: the time- resolved imaging of in-vivo microstructures. Serving as an excellent introductory text and reference source for microscopists, computer scientists, and researchers in biology and clinical medicine, this book also contains over 150 illustrations, many in color, as well as a fold-out poster of a computer-generated image of cell mitosis.
