Abstract
This work tries to achieve the image quality of TFM and M-PWI with a single plane-wave insonification to provide ultra-fast imaging at frame rates of tens of KHz. This is achieved by weighting the plane wave image with a phase coherence factor that keeps in-focus indications and suppresses spurious signals. The bases of the new Plane Wave with Phase Coherence Imaging (PWPCI) are described. Experimental work is also carried out to contrast the image quality with that provided by the well established gold standard TFM. This work demonstrates that the proposed PWPCI technique provides similar or superior image quality than TFM at significantly higher frame rates.
