  • 3D FDTD modeling of a clinical system for microwave imaging
  • 2010
  • In: 2010 IEEE International Conference on Wireless Information Technology and Systems, ICWITS 2010. - 9781424470914
  • Conference paper (other academic/artistic)abstract
    • There is a need for novel breast cancer detection systems to overcome the limitations with today's modalities. Microwave based system has the potential to become both sensitive and specific in this application. We have studied and evaluated a possible design for a clinical system as well as developed an accurate image reconstruction algorithm to work with this system. © 2010 IEEE.

  • 2011
  • In: 7th Loughborough Antennas and Propagation Conference, LAPC 2011, Loughborough, 14 November through 15 November 2011. - 9781457710155
  • Conference paper (peer-reviewed)abstract
    • In this paper we describe a microwave based measurement setup and a signal processing algorithm for stroke detection and diagnostics. We conclude that the technique is feasible and clinical studies show promising results and encourage further investigations.

  • Antenna Modeling and Reconstruction Accuracy of Time Domain-Based Image Reconstruction in Microwave Tomography
  • 2013
  • In: International Journal of Biomedical Imaging. - : Hindawi Limited. - 1687-4188 .- 1687-4196. ; 2013
  • Journal article (peer-reviewed)abstract
    • Nonlinear microwave imaging heavily relies on an accurate numerical electromagneticmodel of the antenna system. The model is used to simulate scatteringdata that is compared to its measured counterpart in order to reconstruct the image. In this paper an antenna system immersed in water is used to image differentcanonical objects in order to investigate the implication of modeling errors on thefinal reconstruction using a time domain-based iterative inverse reconstruction algorithmand three-dimensional FDTD modeling. With the test objects immersedin a background of air and tap water, respectively, we have studied the impact ofantenna modeling errors, errors in the modeling of the background media, and madea comparison with a two-dimensional version of the algorithm. In conclusion evensmall modeling errors in the antennas can significantly alter the reconstructed image. Since the image reconstruction procedure is highly nonlinear general conclusions arevery difficult to make. In our case it means that with the antenna system immersedin water and using our present FDTD-based electromagnetic model the imagingresults are improved if refraining from modeling the water-wall-air interface andinstead just use a homogeneous background of water in the model.
