Super-resolution in high contrast media
Habib Ammari, Hai Zhang
A mathematical theory is developed to explain the super-resolution and super-focusing in high contrast media. The approach is based on the resonance expansion of the Green function…
Multi-frequency acousto-electromagnetic tomography
Giovanni S. Alberti, Habib Ammari, Kaixi Ruan
This paper focuses on the acousto-electromagnetic tomography, a recently introduced hybrid imaging technique. In a previous work, the reconstruction of the electric permittivity of…
Magnetic resonance-based reconstruction method of conductivity and permittivity distributions at the Larmor frequency
Habib Ammari, Hyeuknam Kwon, Yoonseop Lee +2
Magnetic resonance electrical property tomography is a recent medical imaging modality for visualizing the electrical tissue properties of the human body using radio-frequency magn…
Stability Analysis for Magnetic Resonance Elastography
Habib Ammari, Alden Waters, Hai Zhang
We consider the inverse problem of finding unknown elastic parameters from internal measurements of displacement fields for tissues. The measurements are made on the entirety of a…
Electrical impedance tomography-based pressure-sensing using conductive membrane
Habib Ammari, Kyungkeun Kang, Kyounghun Lee +1
This paper presents a mathematical framework for a flexible pressure-sensor model using electrical impedance tomography (EIT). When pressure is applied to a conductive membrane pat…
Viscoelastic modulus reconstruction using time harmonic vibrations
Habib Ammari, Jin Keun Seo, Liangdong Zhou
This paper presents a new iterative reconstruction method to provide high-resolution images of shear modulus and viscosity via the internal measurement of displacement fields in ti…
