Interpolated Plane Wave Imaging (IPWI): Overcoming Spatial Aliasing

Abstract

This paper introduces an approach to addressing the challenges posed by sub-Nyquist spatial sampling in ultrasound image generation, particularly in the context of Plane Wave Imaging (PWI). Sub-Nyquist sampling can lead to artifacts that compromise image accuracy. To overcome this, we present an interpolation technique for PWI, which resolves the limitations imposed by the sampling theorem. This technique not only improves image quality but also enhances acquisition speed, offering a valuable solution for real-time inspections.
