Artefact


 * Reference for term: Musculoskeletal ultrasound - Holsbeeck Van, M. et al.
 * Appearance in a sonogram which is not a true representation of the scanned object.
 * Reference for definition: Basic Ultrasound - Meire, H.B. &amp; Farrant, P.
 * Comment: Artefacts are not necessarily bad, some artefacts may facilitate making the correct diagnosis. A distinction has to be made between good and bad artefacts.
