Аннотация:To reveal the nature of artifacts in ultrasound images of human lungs (so-called B-lines), experimental phantoms were created consisting of a silicone layer for acoustic imitation of intercostal muscles, a layer formed with finely pored foam burn dressing imitating healthy or edematous lung tissue, a foam dressing fragment, a mandarin juice sac, and a drop of ultrasound gel imitating the structures of the lung tissue. Ultrasound (US) images were recorded with a linear ultrasonic probe L7-4 connected to a Verasonics V-1 scanner. Additionally, an image of a mandarin juice sac located on the surface of the water was constructed using the synthetic aperture method with an Olympus focused piezoelectric transducer. The resulting echograms were compared with images recorded in clinical cases of pulmonary pathologies. It is shown that the appearance of B-lines is associated with the effects of multiple reverberation in liquid-filled structures imitating lung tissue, while their brightness and width on the echogram depend on the characteristic size of the internal structure of the phantom.
