TDOA-based microwave imaging algorithm for real-time microwave ablation monitoring

An Improved Time-Reversal-Based Target Localization for Through-Wall Microwave Imaging

Recently, time reversal (TR) method, due to its high functionality in heterogeneous media has been widely employed in microwave imaging (MI) applications. One of the applications turning into a great interest is through-wall microwave imaging (TWMI). In this paper, TR method is applied to detect and localize a target obscured by a brick wall using a numerically generated data. Regarding this, i...

Microwave Imaging Algorithms Based on Genetic Algorithm

In this thesis, the GA-based reconstruction algorithms were optimized by various techniques, the choice of the best setting, acceleration by custom hardware, and by taking advantages of the problem nature (i.e., if a high contrast exists). Those techniques are applied for 1D and 2D only. We showed that the choice of the appropriate settings for the GA parameters for 1D inverse scattering proble...

Thermographic real-time-monitoring of surgical radiofrequency and microwave ablation in a perfused porcine liver model

Radiofrequency ablation (RFA) and microwave ablation (MWA) are currently the dominant modalities to treat unresectable liver tumors. Monitoring the ablation process with b-mode-sonography is often hampered by artefacts. Furthermore, vessels may cause cooling in the adjacent tumor target (heat-sink-effect) with risk of local recurrence. The present study evaluated infrared-thermography to monito...

Microwave Imaging Using SAR

Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
