What is artifact in X-ray?
An artifact on an image is a feature that does not correlate with the physical properties of the subject being imaged and may confound or obscure interpretation of that image. In this article, examples of artifacts from flat-panel detector–based digital radiographic systems are presented.
What is an artifact in the lung?
Conclusion. Lung atelectasis, consolidation, and/or pleural effusion may create a mirror image, intracardiac artifact in mechanically ventilated patients. The latter was termed the ‘cardiac-mass lung’ artifact, to emphasize the important diagnostic role of both echocardiography and lung echography in these patients.
What is the most common type of artifact in radiography?
Common artifacts (all forms of radiography) radiopaque objects on/external to the patient (e.g. jewelry (e.g. necklaces, piercings), clothing (e.g. buttons), hair (e.g. ponytail, hair braids etc.)
What are artifacts in images?
An image artifact is any feature which appears in an image which is not present in the original imaged object. An image artifact is sometime the result of improper operation of the imager, and other times a consequence of natural processes or properties of the human body.

What are Monitor artifacts?
Visual artifacts are graphical imperfections in digital imaging. Within the context of computers, the term is most commonly associated with glitchy visuals that accompany some sort of hardware or software problem. These artifacts can take a myriad of forms depending on what’s causing the issue.
What causes mirror image artifact?
Mirror image artefacts. Mirror image artefact is one of the beam path artefacts. These occur when an ultrasound beam is not reflected directly back to the transducer after hitting a reflective surface, but rather takes an indirect return journey. With mirror image artefact the interrogating ultrasound beam hits an angled, highly reflective
Who invented the X ray machine first?
Medical X-Rays. X-rays are capable of penetrating some thickness of matter.
What is an artifact in radiology?
Radiographic Artifacts. 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.
