Conference Paper Description

Lung ultrasonography (LUS) is a recent evaluation method for many thoracic diseases. Thoracic acoustic mismatch produces some artifact patterns in the ultrasound B-mode imaging that can be related to specific types of lung diseases. In this study, a simulation method of a LUS phantom was proposed to evaluate artifacts origins. Five configurations of LUS phantom were implemented using the k-wave MATLAB toolbox. The first simulation aimed to achieve A-lines images and the others aimed to achieve B-lines images. A-lines could be seen as reverberation artifacts and B-line as an artifact probably originated by an acoustic trap for the signal.
