Component Based Modeling of Ultrasound Signals
Yael Yankelevsky, Zvi Friedman, Arie Feuer
This work proposes a component based model for the raw ultrasound signals acquired by the transducer elements. Based on this approach, before undergoing the standard digital proces…
Stable Support Recovery of Stream of Pulses with Application to Ultrasound Imaging
Tamir Bendory, Avinoam Bar-Zion, Dan Adam +2
This paper considers the problem of estimating the delays of a weighted superposition of pulses, called stream of pulses, in a noisy environment. We show that the delays can be est…
Super-resolution on the Sphere using Convex Optimization
Tamir Bendory, Shai Dekel, Arie Feuer
This paper considers the problem of recovering an ensemble of Diracs on a sphere from its low resolution measurements. The Diracs can be located at any location on the sphere, not…
Exact recovery of non-uniform splines from the projection onto spaces of algebraic polynomials
Tamir Bendory, Shai Dekel, Arie Feuer
In this work we consider the problem of recovering non-uniform splines from their projection onto spaces of algebraic polynomials. We show that under a certain Chebyshev-type separ…
Exact recovery of Dirac ensembles from the projection onto spaces of spherical harmonics
Tamir Bendory, Shai Dekel, Arie Feuer
In this work we consider the problem of recovering an ensemble of Diracs on the sphere from its projection onto spaces of spherical harmonics. We show that under an appropriate sep…
Sparse Sampling in Helical Cone-Beam CT Perfect Reconstruction Algorithms
Tamir Bendory, Arie Feuer
In the current paper we consider the Helical Cone Beam CT. This scanning method exposes the patient to large quantities of radiation and results in very large amounts of data being…
