What common error can lead to the visualization of ghost images?

The visualization of ghost images in radiography is primarily caused by the presence of radiopaque objects that are not removed before taking the x-ray, such as jewelry. When a radiograph is taken with these objects still in place, they can cast a shadow or an image that appears as a "ghost" on the final film, leading to confusion during diagnosis and treatment planning.

In this context, failing to remove jewelry results in image artifacts that can obscure important anatomical details or misrepresent the true structure of the area being examined. It is essential for clinicians and patients to ensure that any extraneous objects are removed to achieve the clearest possible image and accurate diagnostic results.
