Artefacts in Thoracic Ultrasound

Today, technological evolution increasingly in,proves the quality of ultrasound i1nages, 1nak­ing artefacts less visible; the sonographer thus risks not paying enough attention to the1n. ln generai te1ms, artefacts in n1edical imaging often hamper the diagnostic process since, by definiti on, they are altered representations of ana­tomical reality. In ultrasound, however, this is not always true because by understanding artefacts we are provided with infor1nation on the type of interaction that ultrasounds have with anatomi­cal structures and this can help us to interpret i1nages correctly [I]. In particular, in thoracic ultrasound (TUS) son1e artefacts are responsible for funda1nental sen1iological signs (e.g. B-lines).
