A method for detecting and reducing reverberation artifacts in ul-trasound image sequences is described. A reverberation artifact localization map is produced using local Rf-bandwidth estimation. To reduce the artifacts an ideal 3D (2D + time) Wiener filter function is computed by using the reverberation map to interactively produce an estimate of the noise(More)
OBJECTIVES/HYPOTHESIS To develop a clinical prognostic model to identify Bell's palsy patients with risk for nonrecovery at 12 months. STUDY DESIGN Data from a prospective, randomized, double-blind, placebo-controlled, multicenter study. METHODS There were 829 patients with Bell's palsy randomized in a factorial fashion to treatment with prednisolone or(More)
One of the most frequently occuring artifacts in ultrasound imaging is reverberations. These are multiple reflection echoes that result in ghost echoes in the ultrasound image. A method for reducing these unwanted artifacts using a three-dimensional (3D) Wiener filter is presented. The Wiener filter is a global filter and produces an estimate of the(More)
