Computed Tomography From Photon Statistics to Modern Cone-Beam CT [Paperback]

This volume provides an overview of X-ray technology and the historical development of modern CT systems. The main focus of the book is a detailed derivation of reconstruction algorithms in 2D and modern 3D cone-beam systems. A thorough analysis of CT artifacts and a discussion of practical issues such as dose considerations give further insight into current CT systems. Although written mainly for graduate students, practitioners will also benefit from this book.

Tis 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. Te basis of reconstr- 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. Terefore, the reader will ?nd a number of references to these basic disciplines together with a brief introd- tion to the underlying principles of CT. Tis book is structured to cover the basics of CT: from photon statistics to m- ern cone-beam systems. However, the main focus of the book is concerned with - 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 engine- ing science, medical physics, medicine (radiology), mathematics, electrical eng- eering, and physics, experienced practitioners in these ?elds will bene?t from this book as well.Fundamentals of X-ray Physics.- Milestones of Computed Tomography.- Fundamentals of Signal Processing.- Two-Dimensional Fourier-Based Reconstruction Methods.- Algebraic andls’
