Plane Wave Imaging (PWI)

PWI is essentially a sectorial scan firing all the elements of the array with few angles for emission while receiving on all elements without delay laws for reception. Like FMC, Plane Wave Imaging (PWI) is designed to insonify the largest possible volume of the medium in a single shot. By using broad, unfocused plane waves instead of individual focused beams, PWI ensures wide-area coverage with each transmission. The goal is to fire less times than elementary FMC to increase productivity.
