We are in the midst of major advances in medical imaging, converting static pre sentation of anatomic information into near real-time interactive imaging and displays capable of depicting both structure and function. This will have pro found impact on diagnosis and image-guided therapies. These advances have been most notable in the modalities of computed tomog raphy and magnetic resonance. These technologies have become capable of ac quiring volumetric images in short periods of time. Speed gains in MRI were very significant in the early 1990s with the development of clinically usable pulse se quences for gradient-recalled and echo-planar imaging. It appears that further speed gains in MRI will be difficult to achieve. The development of spiral CT has ushered in an era in which major speed gains in CT are also possible. This has enabled creation of new types of applica tions such as CT angiography, which has already come to replace catheter angio graphy at many medical centers throughout the world. We are very pleased that the results from industrial and academic laboratories have been transferred to the bedside to improve patient care at a speed that may be faster than in any other area of medicine. Concurrent with advances in CT technology there have been dramatic strides in the performance characteristics and costs of computer hardware and software.

Significant development made in the Siemens CT scanner SOMATOM PLUS have opened new possibilities for diagnostic imaging in computed tomography. Spiral CT with a continously rotating X-ray tube and synchronous table increments for up to 60 cm in less than half a minute make radiological diagnosis more accurate. Blind gaps are no longer a major problem, and all structures, especially in the lungs, can be identified and diagnosed. The practical experience of an expert groupof clinical researchers and physicists is now made available in this book.

An imaging procedure that involves the use of computer-processed combinations of many X-ray measurements is known as computed tomography or X-Ray CT. These X-ray measurements are taken from different angles in order to create cross-sectional images. The measurement focuses on specific areas of the scanned object. This technique is beneficial as it helps users to see inside the object without cutting. The most common application of X-ray computed tomography is medical imaging. Cross section images of this procedure are utilized for diagnostic and therapeutic purposes in various medical disciplines. Apart from X-ray CT, there are some other types of computed tomography such as positron emission tomography and single photon emission computed tomography. CT is also used in various other fields, such as nondestructive materials testing. It also has archaeological uses such as imaging the contents of sarcophagi and ceramics. This book contains some path-breaking studies in the field of computed tomography. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. The book is appropriate for students seeking detailed information in this area as well as for experts.

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.

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.
