Application of additive manufacturing for the adaptive design of ultrasound phantoms

Frontiers in Physics
IntroductionThe image formation process of conventional pulse-echo Ultrasound mainly uses the backscattered amplitude and assumes constant attenuation and speed of sound in the penetrated media.
