When viewing a particular region <strong>of</strong> interest, techniques such as using a small<br />
light source and moving the radiograph over the small light source, or<br />
changing the intensity <strong>of</strong> the light source will help the radiographer identify<br />
relevant indications. Magnifying tools should also be used when appropriate<br />
to help identify and evaluate indications. Viewing the actual component being<br />
inspected is very <strong>of</strong>ten helpful in developing an understanding <strong>of</strong> the details<br />
seen in a radiograph.<br />
Interpretation <strong>of</strong> radiographs is an acquired skill that is perfected over time.<br />
By using the proper equipment and developing consistent evaluation<br />
processes, the interpreter will increase his or her probability <strong>of</strong> detecting<br />
defects.<br />
