CT This book provides an overview of X-ray technology, the historic developmental milestones of modern CT systems, and gives a comprehensive insight into the main reconstruction methods used in computed tomography. The basis of reconstruc- tion is, undoubtedly, mathematics. However, the beauty of computed tomography cannot be understood without a detailed knowledge of X-ray generation, photon– matter interaction, X-ray detection, photon statistics, as well as fundamental signal processing concepts and dedicated measurement systems. Therefore, the reader will find a number of references to these basic disciplines together with a brief introduc- tion to the underlying principles of CT. This book is structured to cover the basics of CT: from photon statistics to mod- ern cone-beam systems. However, the main focus of the book is concerned with de- tailed derivations of reconstruction algorithms in D and modern D cone-beam systems. A thorough analysis of CT artifacts and a discussion of practical issues, such as dose considerations, provide further insight into modern CT systems. While mainly written for graduate students in biomedical engineering, medical engineer- ing science, medical physics, medicine (radiology), mathematics, electrical engin- eering, and physics, experienced practitioners in these fields will benefit from this book as well.
