Describe the components of the CT imaging system, and differentiate between conventional and spiral/helical CT scanning. List the CT computer data processing steps, and name the functions of the array processor used for image reconstruction. At the same time define the term "algorithm" and explain its impact on image scan factors and reconstruction and define the terms "raw data" and "image data.", and explain the difference between reconstructing and reformatting an image. Also describe the application of data acquisition and process terms to CT and identify the types and appearance of artifacts most commonly affecting CT images and explain how artifacts can be reduced or eliminated. This course list and describe current data storage techniques used in CT and name the radiation protection devices that can be used to reduce patient dose in CT and describe the correct application of each.
