What are artifacts in radiographic images?

Artifacts in radiographic images refer to unwanted imperfections that can obscure defects in the material being examined. These artifacts can arise from various sources, such as equipment malfunction, improper exposure settings, or even environmental factors. They can manifest as streaks, spots, or irregularities in the image and can distract from or completely hide critical information necessary for accurate interpretation. Understanding and identifying these artifacts is crucial for ensuring the integrity and reliability of radiographic testing results.

In contrast, digital enhancements aimed at improving clarity generally work to refine the image rather than impart imperfections. Standard features of radiographic images are expected characteristics related to the imaging process, and enhancements for brightening dark images serve a different purpose entirely — they are intended to optimize visibility, rather than presenting flaws. Thus, recognizing the nature of artifacts is fundamental for maintaining the quality of radiographic assessments.
