Abstract: Null subtraction imaging (NSI) is a non-linear beamformer that aims to improve the spatial resolution of ultrasound images. NSI incoherently combines three delay-and-sum (DAS) outputs from ...
Abstract: In this paper, a approach with a tunable null width of the radiation pattern is proposed and validated on a linear patch antenna array. The optimal excitation distribution (OED) is optimized ...
