DOI: 10.1007/s11548-017-1698-y
Abstract: PurposeWe propose a novel framework for enhancement and localization of steeply inserted hand-held needles under in-plane 2D ultrasound guidance.MethodsDepth-dependent attenuation and non-axial specular reflection hinder visibility of steeply inserted needles. Here, we model signal transmission… read more here.
