X-RAY IMAGING: COMPUTED TOMOGRAPHY

Beginning with a brief history of CT scanner development through the 1970s and 1980s, this programcovers the technical aspects of x-radiation, image processingand construction, as well as, the Hounsfield unit scale. We discuss safety protocols, including use of CT in pregnancy and in patients with implanted devices.Contrast agents are explained, along with a section on general useage protocols. The Interpretation segment of the program covers windowing along with artifacts and the means of minimizing them. The program concludes with a brief overview of new technology in computed tomography scanning.
