What is an image artifact and how can it be minimized?

An image artifact is an unintended irregularity on a radiographic image that does not reflect the actual anatomy. It can be caused by patient motion, hardware in the imaging chain, or processing factors. To minimize artifacts, focus on immobilizing the patient to prevent movement, using proper technique for correct positioning and appropriate exposure, and maintaining the equipment and software to prevent calibration or processing errors. Deliberate features, or the idea of an image being always perfect, don’t describe artifacts, and artifacts can arise from more than just computer errors, so addressing motion, hardware, and processing covers the common sources.
