What does artifact mean on ultrasound?
Artifacts are any alterations in the image which do not represent an actual image of the examined area.
They may be produced by technical imaging errors or result from the complex interaction of the ultrasound with biological tissues..
What are physical artifacts?
Artifacts are physical objects created and used by humans. Artifacts may include such items as eating utensils, tools, clothing, and coins. When written records are scarce, these items help researchers discover how people lived.
Can a person be an artifact?
If humans are the products of deliberate design, either humans are artifacts or (if we’re sufficiently uncomfortable with that classification) the definition of artifacts needs to be revisited/revised. If humans are not designed, we cannot be artifacts.
What is the best example of an artifact?
An artifact can be anything and will be different for each person. Some examples may be: trophy or medals, pictures, family heirlooms, a favorite book, a favorite toy from when you were little, jewelry, clothing, sports equipment, any other object that reminds you of something important.

What is the concept of artifact for you?
Artifact is a combination of two Latin words, arte, meaning “by skill” and factum which means “to make.” Usually when you use the word artifact, you are describing something crafted that was used for a particular purpose during a much earlier time. …
What causes mirror image artifact?
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. … It is reflected off into surrounding soft tissue (angle of incidence = angle of reflection).
What does artifact mean?
1a : a usually simple object (such as a tool or ornament) showing human workmanship or modification as distinguished from a natural object especially : an object remaining from a particular period caves containing prehistoric artifacts.
What is an example of an artifact?
Examples include stone tools, pottery vessels, metal objects such as weapons and items of personal adornment such as buttons, jewelry and clothing. Bones that show signs of human modification are also examples.
What are different types of artifacts?
4 Types of ArtifactHistorical & Cultural. Historic and cultural items such as a historic relic or work of art.Media. Media such as film, photographs or digital files that are valued for their creative or information content.Knowledge. … Data.
What is acoustic shadowing in ultrasound?
The phenomenon of acoustic shadowing (sometimes, somewhat tautologically, called posterior acoustic shadowing) on an ultrasound image is characterized by a signal void behind structures that strongly absorb or reflect ultrasonic waves. It is a form of imaging artifact.
How do you avoid ultrasound artifacts?
One can simply avoid this artifact by shielding or turning off all elec- trical equipment to ensure that the artifact does not hinder proper examination of the cardiac anatomy. Cauterization artifact is another example of how external electrical equipment can cause distorted ultrasound images.
What is an artifact on an image?
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.
