Journal ArticleDOI
Elastography: ultrasonic estimation and imaging of the elastic properties of tissues.
Jonathan Ophir,S.K. Alam,Brian S. Garra,Faouzi Kallel,Elisa E. Konofagou,Thomas A. Krouskop,Tomy Varghese +6 more
TL;DR: The strain filter formalism and its utility in understanding the noise performance of the elastographic process is given, as well as its use for various image improvements.
Journal ArticleDOI
A least-squares strain estimator for elastography
Faouzi Kallel,Jonathan Ophir +1 more
TL;DR: It is demonstrated that the LSQSE results in an increase of the elastographic sensitivity (smallest strain that could be detected), thereby increasing the strain dynamic range and reducing the strain contrast and spatial resolution.
Journal ArticleDOI
Elastography: Imaging the elastic properties of soft tissues with ultrasound

TL;DR: This paper summarizes the work in the field of elastography over the past decade, and discusses the basic principles and limitations that are involved in the production ofElastography of biological tissues.
Journal ArticleDOI
Elastographic characterization of HIFU-induced lesions in canine livers.
Raffaella Righetti,Raffaella Righetti,Faouzi Kallel,R. Jason Stafford,Roger E. Price,Thomas A. Krouskop,John D. Hazle,Jonathan Ophir +7 more
TL;DR: Elastography has the potential to become a reliable and accurate modality for HIFU therapy monitoring and a high correlation between the damaged areas as depicted by the elastograms and the corresponding areas as measured from the gross pathology photographs was found.

The Future of Biomedical UltrasoundElastographic imaging
Jonathan Ophir,Brian S. Garra,Faouzi Kallel,Elisa E. Konofagou,Thomas A. Krouskop,Raffaella Righetti,Tomy Varghese +6 more
TL;DR: Tissue may exhibit viscoelastic and poroelastic behavior such as hysteresis, fluid flow, stress relaxation and creep, and describing the mechanical behavior of tissue mathematically requires considerable simplification, if the model is to be useful in a real-time or nearly real- time situation.
