  • Diffraction Tomography

    There are several kinds of diffraction tomography (DT) relationships in relationship with the measurement configuration, but this chapter focuses on the common offset configuration. In general, a DT relationship requires more approximations than does the linearization provided by the BA. The effective maximum view angle is difficult to be predicted in a theoretical way, but in general it can be heuristically evaluated from the data. The chapter demonstrates the calculation of the available horizontal resolution, although the horizontal resolution cannot be separated from the vertical one, because the two quantities are correlated within the DT relationships. DT also provides an approximated but powerful tool to calculate the spatial step needed for taking GPR measurements correctly. The chapter also shows that GPR data can be processed either in the frequency domain or in the time domain.

  • Three-Dimensional Diffraction Tomography

    The (first-order) Born approximation (BA) in 3D can be introduced in the same way as done in 2D, namely approximating the internal field with the incident one. It is important to outline that the spectral weight tends to zero all over the bound of the visible circle, so that the ?>actual?> retrievable spectral set is never equal to the ideal one, in the sense that it would not be equal to the ideal set even if the measurement plane surface were unlimited, analogously to what happened in 2D. The spatial step and the transect or, in other terms, the spatial needed steps along the direction of the movement of the antennas and along the horizontal direction orthogonal to this are driven by the Nyquist criterion. In order to estimate the horizontal (and then the vertical) resolution, the same steps as implemented in the 2D case can be followed.

  • XRay Imaging and Computed Tomography

  • Ionospheric Tomography

    Proposals for tomographic-reconstruction techniques, using ?>differential Doppler?> data gained from the signals of polar-orbiting navigation satellites, began to appear around 1980. The reconstruction results are two- dimensional electron-density distributions, e.g., in height and geographic latitude. In mid- and high latitudes, the height range from about 200 to 600 km is covered; in the surroundings of the equatorial anomaly, the upper limit can be considerably higher. The horizontal range depends on the number and the spacing of the receiving stations. A typical range is 15 degrees. In recent years, several different reconstruction methods have been worked out. Some of them are have found practical application and are used in the production of two-dimensional electron-density profiles. All techniques suffer from the inherent problem that the data set available for the reconstruction is necessarily incomplete. Therefore, additional information has to be used, and it is not possible to select only one reconstruction method that should give the most plausible results under all conditions. Most of the reconstruction methods that have been published fall into the categories of ?>pixel?> methods (matrix reconstruction) or ?>model?> methods (fitting of model parameters). The main differences are found in the inversion techniques, and in the way a p riori information about plausible electron- density distributions is incorporated. Incoherent-scatter radars can give the height dependence of electron density over the height range covered by ionosphere tomography. In general, such profiles are not available for the locations and observation times of satellite passes. The second-best way to gain additional information is the use of true height profiles from ionosondes, or, at least, the use of ionogram parameters. If no additional data exist from observations, one has to fall back to model considerations. (The large experience with ionospheric data and ionospheric physics that is now available allows filling in for missing information in a consistent way, and assessing the plausibility of the two- dimensional electron-density distributions from different reconstruction methods by inspecting the results.) The newest developments in observation possibilities allow one to overcome the inherent weakness of ground-based ionospheric tomography by using the global Navigation Satellite Systems (GNSS: the Global Positioning System, GPS, and/or its Russian equivalent, GLONASS), and reception of the navigation-beacon signals from satellites in low-Earth orbits. Shortly before Earth occultation of the signals, the rays connecting transmitters and receivers are nearly horizontal, and provide the information missing in ground-based tomography. Presently, one receiving satellite exists, and several more will be launched in the near future. Of course, the electron content along near-horizontal rays is only one part of the data system for tomographic reconstruction. It provides information about the average height distribution of ionization. Classical inversion techniques allow retrieval of just this information. Ground-based reception of satellite- beacon signals can provide complimentary information about the horizontal distribution of ionization. The old navigation systems are fading out, but their satellites in low polar orbits will continue to transmit signals for several years, and can provide th...

  • Negative Quantum Channels:An Introduction to Quantum Maps that are Not Completely Positive

    This book is a brief introduction to negative quantum channels, i.e., linear, trace-preserving (and consistent) quantum maps that are not completely positive. The flat and sharp operators are introduced and explained. Complete positivity is presented as a mathematical property, but it is argued that complete positivity is not a physical requirement of all quantum operations. Negativity, a measure of the lack of complete positivity, is proposed as a tool for empirically testing complete positivity assumptions. Table of Contents: Preface / Acknowledgments / Introduction and Definition of Terms / Tomography / Non-Positive Reduced Dynamics / Complete Positivity / Physical Motivation of Complete Positivity / Measures of Complete Positivity / Negative Channels / Negative Climates with Diagonal Composite Dynamics / Rabi Channels / Physical Motivations for Sharp Operations / Negative Qubit Channel Examples with Multi-Qubit Baths / Proposed Experimental Demonstration of Negativity / Implicatio s of Negative Channels / Uses for Negative Channels / Conclusions / Bibliography / Author's Biography

  • Introductory Medical Imaging

    This book provides an introduction to the principles of several of the more widely used methods in medical imaging. Intended for engineering students, it provides a final-year undergraduate- or graduate-level introduction to several imaging modalities, including MRI, ultrasound, and X-Ray CT. The emphasis of the text is on mathematical models for imaging and image reconstruction physics. Emphasis is also given to sources of imaging artefacts. Such topics are usually not addressed across the different imaging modalities in one book, and this is a notable strength of the treatment given here. Table of Contents: Introduction / Diagnostic X-Ray Imaging / X-Ray CT / Ultrasonics / Pulse-Echo Ultrasonic Imaging / Doppler Velocimetry / An Introduction to MRI

  • Landmarking and Segmentation of 3D CT Images

    Segmentation and landmarking of computed tomographic (CT) images of pediatric patients are important and useful in computer-aided diagnosis (CAD), treatment planning, and objective analysis of normal as well as pathological regions. Identification and segmentation of organs and tissues in the presence of tumors are difficult. Automatic segmentation of the primary tumor mass in neuroblastoma could facilitate reproducible and objective analysis of the tumor's tissue composition, shape, and size. However, due to the heterogeneous tissue composition of the neuroblastic tumor, ranging from low-attenuation necrosis to high-attenuation calcification, segmentation of the tumor mass is a challenging problem. In this context, methods are described in this book for identification and segmentation of several abdominal and thoracic landmarks to assist in the segmentation of neuroblastic tumors in pediatric CT images. Methods to identify and segment automatically the peripheral artifacts and tissu s, the rib structure, the vertebral column, the spinal canal, the diaphragm, and the pelvic surface are described. Techniques are also presented to evaluate quantitatively the results of segmentation of the vertebral column, the spinal canal, the diaphragm, and the pelvic girdle by comparing with the results of independent manual segmentation performed by a radiologist. The use of the landmarks and removal of several tissues and organs are shown to assist in limiting the scope of the tumor segmentation process to the abdomen, to lead to the reduction of the false-positive error, and to improve the result of segmentation of neuroblastic tumors.

  • Biomedical EM, Optics, and Ultrasound

    This chapter discusses some key formulations in biomedical electromagnetics (EM). Extensive work has been reported on static through terahertz coupling to bodies near fields, cell phones, specific absorption rate (SAR), narrow and UWB pulse in biological systems. The chapter considers specific absorption rate (SAR) and heat diffusion in tissues. It describes the diffusion approximation of the radiative transfer theory. In the diffusion approximation, the specific intensity has a broad angular spectrum and therefore the diffused wave cannot be focused into a small volume. There is a way to focus the diffused wave, but the focusing requires constructive interference near the focal point and destructive interference elsewhere. The chapter also discusses fundamentals of ultrasound scattering and imaging of tissues and blood. Optical coherence tomography (OCT) was introduced to obtain noninvasive images of biological images of biological tissues with resolutions of 1‐15 μm.
