Abstract:For high-frame-rate ultrasound imaging, it remains challenging to implement on compact systems as a sparse imaging configuration with limited array channels. One key issue is that the resulting image quality is known to be mediocre not only because unfocused plane-wave excitations are used, but also because grating lobes would emerge in sparse array configurations. In this paper, we present the design and use of a new channel recovery framework to infer fullarray plane-wave channel datasets for periodically sp… Show more
