Available in PDF, EPUB and Kindle. Book excerpt: Spectral, Photon Counting Computed Tomography is a comprehensive cover of the latest developments in the most prevalent imaging modality (x-ray computed tomography (CT)) in its latest incarnation: Spectral, Dual-Energy, and Photon Counting CT. Disadvantages of the conventional single-energy technique used by CT technology are that different materials cannot be distinguished and that the noise is larger. To address these problems, a novel spectral CT concept has been proposed. Spectral Dual-Energy CT (DE-CT) acquires two sets of spectral data, and Spectral Photon Counting CT (PC-CT) detects energy of x-ray photons to reveal additional material information of objects by using novel energy-sensitive, photon-counting detectors. The K-edge imaging may be a gateway for functional or molecular CT. The book covers detectors and electronics, image reconstruction methods, image quality assessments, a simulation tool, nanoparticle contrast agents, and clinical applications for spectral CT.

Book excerpt: The current single energy concept has run its course, the notion that atomic-energy is all there is to reality. Since the proof of dark-energy, we have struggled to discern what it is. This book states it is a non-atomic form of energy. By doing so, all the Quantum Mechanics and Relativistic equations that have defied physical explanation in the past now make simple, logical sense. Yes, Quantum Mechanics can be understood logically. All it takes is another energy form in the mix. No longer must our theories violate laws of physics. With the Dual Energy Concept, we can explain quantum behavior in a way that is easily understood. Relativity takes a familiar form, and the Cosmos, in all its grand glory, comes into sharp focus. The exciting thing about the Dual Energy Concept is that it uses the Classical Quantum Mechanics equations to do the job! Yes, Schr�dinger, de Broglie, and a host of others were right. The waves they associated with their wave equations are real. They just could not explain how at the time. With the advent of dark-energy, we can. Now, things we thought we knew take on new shape, a deeper comprehension of what is real. Quantum MechanicsWhat is a photon?How does a photon move through space?Is a photon a wave or a particle?What is the difference between a particle and a photon?Is mass a property of atomic-energy as well? What about spin? What is a quanta?Why do particles group together?How is a photon created out of nothing?How do the different classes of energy interact?So what is this location node you keep talking about?What are virtual particles?How do particles interact?What is leeching?Do matter waves really exist?Why do particles want to shed mass?Why do particles decay?How are atomic particles created out of the Medium?How does an electron jump from one place to another - without appearing between?How can an electron be everywhere at once?How are the four forces of Nature explained using the Dual Energy Concept? RelativityHow does gravity warp space-time? How does the Dual Energy Concept explain gravity? How does the Dual Energy Concept explain length dilation?Why does a photon slow down in a gravity field? What is an energy (photon) shroud? Why does mass increase as speed increases?What is time?Why does time slow down as a particle accelerates? Why does time slow down in a gravitational field? Is there a common reference plane? The UniverseWas there really a Big Bang?Why isn't there a center to the Universe?Why is the Universe expansion accelerating?What really goes on inside a black hole?What is a dark hole?Are super massive black holes actually dark holes?Do dark holes reside at the center of galaxies?What goes on inside a dark hole?Why do planets and galaxies form around dark matter?Are there also dark suns and dark planets?Will the Universe die?

Book excerpt: This book is a comprehensive and richly-illustrated guide to cardiac CT, its current state, applications, and future directions. While the first edition of this text focused on what was then a novel instrument looking for application, this edition comes at a time where a wealth of guideline-driven, robust, and beneficial clinical applications have evolved that are enabled by an enormous and ever growing field of technology. Accordingly, the focus of the text has shifted from a technology-centric to a more patient-centric appraisal. While the specifications and capabilities of the CT system itself remain front and center as the basis for diagnostic success, much of the benefit derived from cardiac CT today comes from avant-garde technologies enabling enhanced visualization, quantitative imaging, and functional assessment, along with exciting deep learning, and artificial intelligence applications. Cardiac CT is no longer a mere tool for non-invasive coronary artery stenosis detection in the chest pain diagnostic algorithms; cardiac CT has proven its value for uses as diverse as personalized cardiovascular risk stratification, prediction, and management, diagnosing lesion-specific ischemia, guiding minimally invasive structural heart disease therapy, and planning cardiovascular surgery, among many others. This second edition is an authoritative guide and reference for both novices and experts in the medical imaging sciences who have an interest in cardiac CT.

Book excerpt: This cross-disciplinary book documents the key research challenges in the mathematical sciences and physics that could enable the economical development of novel biomedical imaging devices. It is hoped that the infusion of new insights from mathematical scientists and physicists will accelerate progress in imaging. Incorporating input from dozens of biomedical researchers who described what they perceived as key open problems of imaging that are amenable to attack by mathematical scientists and physicists, this book introduces the frontiers of biomedical imaging, especially the imaging of dynamic physiological functions, to the educated nonspecialist. Ten imaging modalities are covered, from the well-established (e.g., CAT scanning, MRI) to the more speculative (e.g., electrical and magnetic source imaging). For each modality, mathematics and physics research challenges are identified and a short list of suggested reading offered. Two additional chapters offer visions of the next generation of surgical and interventional techniques and of image processing. A final chapter provides an overview of mathematical issues that cut across the various modalities.

Available in PDF, EPUB and Kindle. Book excerpt: X-ray computed tomography (CT) continues to experience rapid growth, both in basic technology and new clinical applications. Seven years after its first edition, Computed Tomography: Principles, Design, Artifacts, and Recent Advancements, Second Edition, provides an overview of the evolution of CT, the mathematical and physical aspects of the technology, and the fundamentals of image reconstruction algorithms. Image display is examined from traditional methods used through the most recent advancements. Key performance indices, theories behind the measurement methodologies, and different measurement phantoms in image quality are discussed. The CT scanner is broken down into components to provide the reader with an understanding of their function, their latest advances, and their impact on the CT system. General descriptions and different categories of artifacts, their causes, and their corrections are considered at length. Given the high visibility and public awareness of the impact of x-ray radiation, the second edition features a new chapter on x-ray dose and presents different dose reduction techniques ranging from patient handling, optimal data acquisition, image reconstruction, and post-process. Based on the advancements over the past five years, the second edition added new sections on cone beam reconstruction algorithms, nonconventional helical acquisition and reconstruction, new reconstruction approaches, and dual-energy CT. Finally, new to this edition is a set of problems for each chapter, providing opportunities to enhance reader comprehension and practice the application of covered material.

Available in PDF, EPUB and Kindle. Book excerpt: Game-changing disruptions will likely unfold on your watch. Be ready. In Dual Transformation, Scott Anthony, Clark Gilbert, and Mark Johnson propose a practical and sustainable approach to one of the greatest challenges facing leaders today: transforming your business in the face of imminent disruption. Dual Transformation shows you how your company can come out of a market shift stronger and more profitable, because the threat of disruption is also the greatest opportunity a leadership team will ever face. Disruptive change opens a window of opportunity to create massive new markets. It is the moment when a market also-ran can become a market leader. It is the moment when business legacies are created. That moment starts with the core dual transformation framework: Transformation A: Repositioning today’s business to maximize its resilience, such as how Adobe boldly shifted from selling packaged software to providing software as a service. Transformation B: Creating a new growth engine, such as how Amazon became the world’s largest provider of cloud computing services. Capabilities link: Fighting unfairly by taking advantage of difficult-to-replicate assets without succumbing to the “sucking sound of the core.” Anthony, Gilbert, and Johnson also address the characteristics leaders must embrace: courage, clarity, curiosity, and conviction. Without them, dual transformation efforts can founder. Building on lessons from diverse companies, such as Adobe, Manila Water, and Netflix, and a case study from Gilbert’s firsthand experience transforming his own media and publishing company, Dual Transformation will guide executives through the journey of creating the next version of themselves, allowing them to own the future rather than be disrupted by it.
