What term is used to describe unwanted markings on a radiographic image?

The term used to describe unwanted markings on a radiographic image is "artifacts." In radiography, artifacts can result from various sources, such as equipment malfunction, improper technique, or external influences that affect the image quality. These unwanted features can obscure important details, leading to misinterpretation and potentially impacting diagnosis. Recognizing and identifying artifacts is crucial in medical imaging to differentiate them from genuine anatomical structures or pathological conditions, ensuring accurate readings and assessments. The focus on artifacts emphasizes the importance of maintaining quality control and proper imaging practices in radiographic procedures.
