X-ray artifacts can present in a variety of ways including abnormal shadows noted on a radiograph or degraded image quality, and have been produced by artificial means from hardware failure, operator error and software (post-processing) artifacts.
Aug 2, 2016 · Since the early days of radiology, artifacts have appeared on radiographs. Actually, the first radiograph ever taken had an artifact present, a metallic ring on the patient’s hand. Artifacts are a common cause of repeat radiographs; they often occur in unexpected places, with many peculiar internal objects being detected.
Artifactual appearances seen on a chest X-ray may be due to radiographic technique, patient factors, or the presence of external or internal non-anatomical objects. Artifact is often unavoidable, but some artifact can lead to misinterpretation of the image.
May 10, 2010 · This document discusses various types of artifacts that can appear on radiographic images, grouping them into categories of processing artifacts, exposure artifacts, and artifacts related to handling and storage. Processing artifacts include hypo retention, pi-lines, guide shoe marks, and static caused by the film development process.
Apr 20, 2018 · This article provides examples of image artifacts found with flat-panel detector–based digital radiography systems, along with an explanation for their appearance, to help radiologists identify, resolve, or prevent their occurrence.

Digital Radiography Image Artifacts. Figure 1 shows a lateral chest image with an unusual superimposed pattern on the anatomy. This is an example of a CR image obtained with cassette reversed, where the tube side of cassette is pointed away from the x-ray tube source and toward the patient.
