Microwave Imaging of Brain Stroke : Contributions to Modeling and Inverse Problem Resolution

Mina Bjelogrlic

Brain stroke is an age-related illness which has become a major issue in our ageing societies. Early diagnosis and treatment are of high importance for the full recovery of the patient, as reminded in Anglo-Saxon countries by the abbreviation FAST (Face, A ...

Experimental verification of optimal frequency range for microwave head imaging

Jean-Philippe Thiran, Juan Ramon Mosig, Michael Mattes, Mina Bjelogrlic, Benjamin Fuchs

This work presents the experimental verification of the power transmission of a radiating field into the human head for Microwave Imaging (MWI) applications. We aim at finding the range of frequencies that optimize the power scattered by any anomalies from ...

On the born approximation for differential microwave imaging using volume integral equation formulation

Juan Ramon Mosig, Michael Mattes, Mina Bjelogrlic, Benjamin Fuchs

The Degree of Non-Linearity (DNL) of scattering problems and specifically of differential Microwave Imaging (dMWI) problems is addressed in this paper. The quantification of the DNL amounts to evaluate the validity range of the Born first order (linear) ap ...

Contributions to 3D differential microwave imaging

Michael Mattes, Mina Bjelogrlic, Benjamin Fuchs

This paper presents new contributions to forward and inverse problems in 3D differential microwave imaging. This technique is well suited to monitor a pathological evolution, for instance the brain stroke of a patient. The forward problem is solved using a ...

Numerical Assessment of Brain Stroke Follow-Up via Differential Microwave Imaging

Juan Ramon Mosig, Michael Mattes, Mina Bjelogrlic

This paper proposes a numerical assessment of brain stroke follow-up via differential Microwave Imaging. The aim is to follow the evolution of the patient’s stroke growth and location, in order to support decisions in the clinical treatment. We present a f ...
