Computed Tomography gives a detailed overview of various aspects of computed tomography. It discusses X-ray CT tomography from a historical point of view, the design and physical operating principles of computed tomography apparatus, the algorithms of image reconstruction and the quality assessment criteria of tomography scanners. Algorithms of image reconstruction from projections, a crucial problem in medical imaging, are considered in depth. The author gives descriptions of the reconstruction methods related to tomography scanners with a parallel X-ray beam, trough solutions with fan-shaped beam and successive modifications of spiral scanners. Computed Tomography contains a dedicated chapter for those readers who are interested in computer simulations based on studies of reconstruction algorithms. The information included in this chapter will enable readers to create a simulation environment in which virtual tomography projections can be obtained in all basic projection systems. This monograph is a valuable study on computed tomography that will be of interest to advanced students and researchers in the fields of biomedical engineering, medical electronics, computer science and medicine.

X-ray computed tomography has been used for several decades as a tool for measuring the three-dimensional geometry of the internal organs in medicine. However, in recent years, we have seen a move in manufacturing industries for the use of X-ray computed tomography; first to give qualitative information about the internal geometry and defects in a component, and more recently, as a fully-quantitative technique for dimensional and materials analysis. This trend is primarily due to the ability of X-ray computed tomography to give a high-density and multi-scale representation of both the external and internal geometry of a component, in a non-destructive, non-contact and relatively fast way. But, due to the complexity of X-ray computed tomography, there are remaining metrological issues to solve and the specification standards are still under development. This book will act as a one-stop-shop resource for students and users of X-ray computed tomography in both academia and industry. It presents the fundamental principles of the technique, detailed descriptions of the various components (hardware and software), current developments in calibration and performance verification and a wealth of example applications. The book will also highlight where there is still work to do, in the perspective that X-ray computed tomography will be an essential part of Industry 4.0.

Medical Setting Considerations for the Speech-Language Pathologist is the first volume in the “Medical Speech-Language Pathology” book series. The series provides graduate students, clinicians, and clinical researchers with functional, comprehensive material to enhance practice in a medical setting. This first book in the series will foster an appreciation of the unique skill set and knowledge base needed by a medical speech-language pathologist. The chapters contain information applicable to a broad range of medical and rehabilitation settings, while delving deeper into complex topics that merit extra attention, such as neuroimaging methods and medication side effects. Readers will come to appreciate the many roles and responsibilities of the speech-language pathologist in the medical setting, across the continuum of care. They will gain familiarity with broader organizational issues, such as accreditation, billing, and medical team members, as well as the specific clinical populations often encountered in medical settings, such as individuals with Parkinson’s disease, delirium, or tongue cancer. Throughout the book, case studies are used to highlight the role of the medical SLP, and to underscore the remarkably dynamic and complex caseloads encountered by the medical SLP. Medical Setting Considerations for the Speech-Language Pathologist is authored by experienced professionals and content experts who transform the research literature into clinically applicable and digestible information, with the series editors Kristie A. Spencer and Jacqueline Daniels leading the cohort.

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

Bone substitute biomaterials are fundamental to the biomedical sector, and have recently benefitted from extensive research and technological advances aimed at minimizing failure rates and reducing the need for further surgery. This book reviews these developments, with a particular focus on the desirable properties for bone substitute materials and their potential to encourage bone repair and regeneration. Part I covers the principles of bone substitute biomaterials for medical applications. One chapter reviews the quantification of bone mechanics at the whole-bone, micro-scale, and non-scale levels, while others discuss biomineralization, osteoductivization, materials to fill bone defects, and bioresorbable materials. Part II focuses on biomaterials as scaffolds and implants, including multi-functional scaffolds, bioceramics, and titanium-based foams. Finally, Part III reviews further materials with the potential to encourage bone repair and regeneration, including cartilage grafts, chitosan, inorganic polymer composites, and marine organisms. Provides a detailed and accurate overview of the bone substitute biomaterials, a fundamental part of the biomaterials and biomedical sector Provides readers with the principles of bone substitute biomaterials Reviews biomaterials for bone regeneration
