The Digitization of NDT Radiographs Using a Laser Scanner for Improved Productivity

  • W. A. GraemeJr.


To properly begin a discussion on the improvement of productivity using radiographs, we must define three terms. First, an NDT radiography is defined as the image of an object on an NDT x-ray film. Second, productivity is defined as the output of the system measured as a percent of effort or what comes out of a system as compared to what was put in. Third, a bottleneck or the limiting factor to productivity, is a facility, function or workstation where jobs arrive faster than they leave. Having defined these terms, we know that eliminating bottlenecks in the radiographic process should increase output and improve productivity. The bottlenecks that occur using radiographs are shown in Table 1.
