Abstract
To determine the nature of artifacts on the ultrasound image 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 fine-pored anti-burn sponge imitating healthy or edematous lung tissue, a sponge fragment, a mandarin juice pouch and a drop of ultrasound gel imitating the structures of the lung fabrics. Ultrasonic (US) images were recorded by a linear ultrasonic probe L7-4 connected to a Verasonics V-1 ultrasound scanner. Additionally, an image of a tangerine juice sac located on the surface of the water was constructed based on the synthesized aperture method using a focused piezoelectric transducer Olympus V307. The resulting echograms were compared with images recorded in clinical cases of pulmonary pathologies. It is shown that the appearance of artificial 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.
