Description

The use of radioscopy (real-time radiography in which film is replaced by an electronic imaging system) is limited by the availability of appropriate image quality indicators (IQIs). Available indicators (plaque and wire type [1,21) were designed for radiographic imaging where the source, imaging system (film), and specimen are stationary and the IQI plane is oriented normal to the flux of radiation. The improvement in productivity made possible by rotating the object during inspection in real-time is inhibited by the lack of an indicator that evaluates image quality as the specimen (and the associated IQI’s) are rotated.
