Book Description
Existing and Potential Standoff Explosives Detection Techniques examines the scientific techniques currently used as the basis for explosives detection and determines whether other techniques might provide promising research avenues with possible pathways to new detection protocols. This report describe the characteristics of explosives, bombs, and their components that are or might be used to provide a signature for exploitation in detection technology; considers scientific techniques for exploiting these characteristics to detect explosives and explosive devices; discusses the potential for integrating such techniques into detection systems that would have sufficient sensitivity without an unacceptable false-positive rate; and proposes areas for research that might be expected to yield significant advances in practical explosives and bomb detection technology in the near, mid, and long term.

Book Description
This is the first book to cover all aspects of the development of imaging biomarkers and their integration into clinical practice, from the conceptual basis through to the technical aspects that need to be considered in order to ensure that medical imaging can serve as a powerful quantification instrument capable of providing valuable information on organ and tissue properties. The process of imaging biomarker development is considered step by step, covering proof of concept, proof of mechanism, image acquisition, image preparation, imaging biomarker analysis and measurement, detection of measurement biases (proof of principle), proof of efficacy and effectiveness, and reporting of results. Sources of uncertainty in the accuracy and precision of measurements and pearls and pitfalls in gold standards and biological correlation are discussed. In addition, practical use cases are included on imaging biomarker implementation in brain, oncologic, cardiovascular, musculoskeletal, and abdominal diseases. The authors are a multidisciplinary team of expert radiologists and engineers, and the book will be of value to all with an interest in the quantitative imaging of biomarkers in personalized medicine.

Book Description
Photonics is a term often used in relation to light-based circuits, but it is actually more inclusive, including the generation, emission, transmission, modulation and signal processing of light. Biophotonics is therefore a term which can be used to describe the development and application of optical techniques for the study of biological molecules, cells and tissues.This book presents some of the most promising new image-based and related technologies which have evolved in the last few years for the study, visualization, characterisation and analysis of abnormal cells and tissues, and discusses their current and potential applications in experimental pathology and clinical pathological diagnosis. The book contains more than a dozen papers contributed by experts in the field, and the technology is described in a manner accessible to an audience of pathologists, cell biologists and biochemists as well as biomedical engineers.Subjects covered include: advanced methods in fluorescence microscopy, automated image interpretation and computer-assisted diagnostics, magnetic resonance microscopy, impedence measurements in the biomedical sciences and raman scattering in pathology, among others.There is an increasing convergence of radiology and pathology, and although this book has been written from the perspective of pathology, it demonstrates a confluence of methodologies similar to those applied in radiology with morphological analysis at the cellular and tissue level, and will also be of interest to radiologists, as well as to other scientists and engineers working in overlapping areas.

Book Description
Biomolecular imaging enables localization and characterization of biomolecules at the cellular and tissue levels in order to better understand their roles in biological organisms. Although a plethora of imaging techniques is available, there is a need to improve current imaging methodologies and apply them for selective analyses of complex biological specimens. The work described in this thesis is related to development and applications of spectral imaging and imaging mass spectrometry (IMS) methodologies. Spectral imaging uses either labeling dyes or native chromophores to visualize biomolecules in cells and tissues under a specialized light microscope, while IMS provides direct detection and analysis of biomolecules on tissue surfaces with preserved spatial distribution. In this initial study, multimodal spectral imaging of cells, cellular organelles, and tissues was performed on a light microscope upon the addition of a transmission diffraction grating. The instrument concurrently recorded spectral images by fluorescence, darkfield, brightfield, and differential interference contrast (DIC) spectral microscopy. Fluorescence signals originating from fluorescently labeled biomolecules in cells were collected through triple or single filter cubes, separated by the grating, and were imaged using a charge-coupled device (CCD) camera. Cellular components such as nuclei, cytoskeleton, and mitochondria were spatially separated by the fluorescence spectra of the fluorophores present in them, providing detailed multi-colored spectral images of cells. Additionally, the grating-based spectral microscope enabled measurement of scattering and absorption spectra of unlabeled cells and stained tissue sections using darkfield and brightfield spectral microscopy, respectively. In the second project, matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) was utilized to visualize the protein spatial distribution on tissue surfaces. Our study has been focused on imaging of proteins in kidney tissue sections originating from apparently healthy (normal) mice and mice with polycystic kidney disease (PKD). Reconstruction of protein ion maps and identification of proteins by on-tissue enzymatic digestion were performed. MALDI-MS images were correlated with histological features obtained by hematoxylin and eosin staining, providing localization of peptides in different parts of the kidney (renal pelvis, medulla, and cortex). Nano-HPLC was coupled with imaging mass spectrometry to identify proteins in kidney tissue sections. Statistical analyses such as principle component analysis (PCA) was employed to achieve tissue classification and differentiate between healthy and diseased tissues. Experiments are underway to discover and validate proteins that can become potential biomarkers of PKD. In summary, we demonstrated that fluorescence, scattering, and absorption spectral images of cells can be acquired by incorporation of a transmission diffraction grating into a light microscope. The present spectral imaging methodology provides a readily affordable approach for multimodal spectral characterization of biological cells and other specimens. A reproducible MALDI-IMS workflow was established and resulted in protein mass distribution maps of normal and PKD kidney tissues. Statistical comparison of MALDI-MS images provides classification of healthy and diseased tissues. Several proteins were localized in tissues and their identity will be further confirmed by HPLC combined with tandem mass spectrometry (MS/MS).
