Fig. 1. Illustrations of drive mechanisms for real-time radiographie inspection
of pipeline welds for the source outside the pipe (upper view, double
wall technique) and for the source inside the pipe (lower view, single wall
technique). Photo from ref. 11; courtesy Southwest Research Institute.
Fig. 2. A microfocus, real-time X-ray image of a ceramic spinel disc
across the diameter showing images of dark inclusions in the size range 50
to 100 um. Geometric magnification was 14X.
Fig. 3. Examples of film and real-time neutron images taken with a mobile,
accelerator-based neutron system. The dark areas show neutron attenuation
due to corrosion in the upper and lower views; test pieces, including a modified
ASTM E545 Type A IQI (middle, left) are visualized in the middle region.

Fig. 4. Two neutron radiographs of an engine, a static view at the left and
a dynamic view at the right. Differences can be seen such as the pipe full
of oil (in the middle of the lower part) in the static view while the dynamic
view at the left shows much less neutron attenuation showing aeration of the
oil in the scavenger pipe. Reference 31, courtesy NDT Centre, Harwell.
Fig. 5. Tomographie image of the tip of a turbine blade showing thinning of
the wall at the left lower region. Wall thinning in the order of 0.05 mm can
be detected. Courtesy, Scientific Measurement Systems, Inc.
