Technique 2010

tomography a radiographic technique that employs motion to show anatomical structures lying in a plane of tissue while blurring or eliminating the detail in images of structures above and below the plane of interest
fulcrum the pivot point around which the x-ray tube and image receptor pivot during the exposure in tomography
tomographic amplitude the total distance the tube travels during tomography
exposure amplitude the total distance the tube travels during the exposure during tomography
blur the streaking or smearing that results in the loss of nearly all recorded detail of objects outside the focal plane
focal plane the region within which the image exhibits satisfactory recorded detail during the tomographic exposure and is controlled by the level of the fulcrum
section thickness the width of the focal plane and is controlled by the exposure angle
Ed Jerman the "father of radiologic technology"; developed a variable kvp exposure system
Arthur Fuchs developed a fixed kvp system
caliper a device used to measure a body part
optimal kvp the maximum kvp level that will produce images with appropriate contrast that are consistantly within acceptance limits.
