Book Description
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 Description
Computed tomography (CT) is a widely used x-ray scanning technique. In its prominent use as a medical imaging device, CT serves as a workhorse in many clinical settings throughout the world. It provides answers to urgent diagnostic tasks such as oncology tumor staging, acute stroke analysis, or radiation therapy planning. Spectral Computed Tomography provides a concise, practical coverage of this important medical tool. The first chapter considers the main clinical motivations for spectral CT applications. In Chapter 2, the measurement properties of spectral CT systems are described. Chapter 3 provides an overview of the current state of research on spectral CT algorithms. Based on this overview, the technical realization of spectral CT systems is evaluated in Chapter 4. Device approaches such as DSCT, kV switching, and energy-resolving detectors are compared. Finally, Chapter 5 summarizes various algorithms for spectral CT reconstructions and spectral CT image postprocessing, and links these algorithms to clinical use cases

Book Description
X-ray computed tomography (CT) has been one of the most popular diagnostic imaging modalities for decades in the clinic for saving patients’ lives or improving their quality of life. This book is an introductory one-stop shop for technological and clinical topics in multi-detector computed tomography (MDCT). Starting with MDCT’s fundamentals in physics and mathematics, the book provides an in-depth introduction to its system architecture and imaging chain, signal detection via energy-integration and photon-counting mechanisms, clinical application-driven scan modes and protocols, analytic and iterative image reconstruction solutions, and spectral imaging – the latest technological advancement in MDCT. The book extends its coverage on image quality assessment under the theory of signal detection and statistical decision. In recognition of its clinical relevance for conspicuity enhancement in angiographic and parenchymal imaging applications, the book features a chapter dedicated to the fundamental (chemical, physical and physicochemical) properties and clinical administration of iodinated contrast agent. The book ends with an outlook of the contrast agents that are novel in material and delivery, and their synergy with spectral MDCT to elevate CT’s contrast resolution in cardiovascular, neurovascular and oncologic applications. This book will be an invaluable reference for researchers, engineers, radiological physicians and technologists, and graduate and senior undergraduate students. Features Provides an accessible introduction to the subject Up to date with the latest advances in emerging technologies and procedures Provides a historical overview of CT technology Xiangyang Tang, PhD, is an imaging scientist with extensive research and development experience in industry (GE Healthcare), academia (Emory University School of Medicine) and the clinic (Emory Healthcare).

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.

Book Description
Multidetector-row CT has dramatically improved the results of computed tomography in all clinical applications, but its beneficial impact has been most striking in vascular imaging. The simplicity of acquisition and the wide availability of equipment make this modality especially suitable for routine clinical application. In this book the basic aspects of multidetector-row CT angiography are comprehensively reviewed. Individual chapters are included on technical principles, image processing techniques and contrast agent administration. All clinical applications are then discussed in depth, with lucid descriptions of the examination technique for particular clinical indications and of the findings that characterize specific diseases. Limitations and advantages in comparison with other imaging modalities are considered. A large number of high-quality black and white and color illustrations help to explain the clinical findings.

Book Description
Biomedical Engineering in Gastrointestinal Surgery is a combination of engineering and surgical experience on the role of engineering in gastrointestinal surgery. There is currently no other book that combines engineering and clinical issues in this field, while engineering is becoming more and more important in surgery. This book is written to a high technical level, but also contains clear explanations of clinical conditions and clinical needs for engineers and students. Chapters covering anatomy and physiology are comprehensive and easy to understand for non-surgeons, while technologies are put into the context of surgical disease and anatomy for engineers. The authors are the two most senior members of the Institute for Minimally Invasive Interdisciplinary Therapeutic Interventions (MITI), which is pioneering this kind of collaboration between engineers and clinicians in minimally invasive surgery. MITI is an interdisciplinary platform for collaborative work of surgeons, gastroenterologists, biomedical engineers and industrial companies with mechanical and electronic workshops, dry laboratories and comprehensive facilities for animal studies as well as a fully integrated clinical "OR of the future". - Written by the head of the Institute of Minimally Invasive Interdisciplinary Therapeutic Intervention (TUM MITI) which focusses on interdisciplinary cooperation in visceral medicine - Provides medical and anatomical knowledge for engineers and puts technology in the context of surgical disease and anatomy - Helps clinicians understand the technology, and use it safely and efficiently
