Abstract
This chapter describes the physical principles and instrumentation of computed tomography (CT) and outlines several recent advances in CT technology. First, the history of CT is presented. Secondly, the essential physical principles are described. Thirdly, the technology of CT including image post-processing such as windowing is explained in detail. The elements of spiral/helical CT principles and technology are also outlined. Finally, multislice CT applications are reviewed followed by a radiation protection overview.
