In addition to producing high quality radiographs, the radiographer must also be skilled in radiographic interpretation.
Interpretation of radiographs takes place in three basic steps: (1) detection, (2) interpretation, and (3) evaluation.
All of these steps make use of the radiographer's visual acuity.
Visual acuity is the ability to resolve a spatial pattern in an image.
The ability of an individual to detect discontinuities in radiography is also affected by the lighting condition in the place of viewing, and the experience level for recognizing various features in the image.
