The book offers an in-depth look at computed tomography and its clinical aspects. Computed tomography is a crucial imaging method in clinical practice, especially, multi-detector-row computed tomography (MDCT). It is an important non-invasive imaging device and has numerous advantages over other such devices. It was the first non-invasive imaging technique to examine internal human body not biased by superimposition of different anatomical structures. It was introduced in 1970s and since then, it has advanced and improved to a great extent. For instances, the introduction of helical systems has allowed the development of "volumetric CT" concept. This book deals with applications of CT not just in medical imaging but also in the fields of physics, archaeology and computer aided diagnosis. Also, in the past few years, anthropomorphic, forensic, paleontological and archeological applications of CT have emerged. Such applications make it a versatile diagnostic technology for non-destructive material testing and 3D imaging, beyond its medical use.
