Economical sponge phantom for teaching, understanding, and researching A- and B-Line reverberation artifacts in lung ultrasound


Blüthgen, Christian; Sanabria, Sergio; Frauenfelder, Thomas; Klingmüller, Volker; Rominger, Marga (2017). Economical sponge phantom for teaching, understanding, and researching A- and B-Line reverberation artifacts in lung ultrasound. Journal of Ultrasound in Medicine, 36(10):2133-2142.

Abstract

This project evaluated a low-cost sponge phantom setup for its capability to teach and study A- and B-line reverberation artifacts known from lung ultrasound and to numerically simulate sound wave interaction with the phantom using a finite-difference time-domain (FDTD) model. Both A- and B-line artifacts were reproducible on B-mode ultrasound imaging as well as in the FDTD-based simulation. The phantom was found to be an easy-to-set up and economical tool for understanding, teaching, and researching A- and B-line artifacts occurring in lung ultrasound. The FDTD method-based simulation was able to reproduce the artifacts and provides intuitive insight into the underlying physics.
