  • Convergence and stability assessment of Newton-Kantorovich reconstrutin algorithms for microwve tomography 

    Joachimowicz, N.; Mallorquí Franquet, Jordi Joan; Bolomey, J. C. (Jean-Charles); Broquetas Ibars, Antoni (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1998-08-31)
    Article
    Open Access
    For newly developed iterative Newton-Kantorovitch reconstruction techniques, the quality of the final image depends on both experimental and model noise. Experimental noise is inherent to any experimental acquisition scheme, ...
  • Database of "in vivo" measurements for quantitative microwave imaging and reconstruction algorithms available 

    Mallorquí Franquet, Jordi Joan; Joachimowicz, N.; Bolomey, J. C. (Jean-Charles); Broquetas Ibars, Antoni (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1995-10-01)
    Article
    Open Access
    Reconstruction algorithms and equipment have been developed for microwave imaging, with emphasis on noninvasive control of deep hyperthermia treatments. Tomographic reconstruction algorithms have also been developed for ...
  • Planar and cylindrical active microwave temperature imaging: numerical simulations 

    Rius Casals, Juan Manuel; Pichot du Mezeray, Christian Yves Dominique; Jofre Roca, Lluís; Bolomey, J. C. (Jean-Charles); Joachimowicz, N.; Broquetas Ibars, Antoni; Ferrando Bataller, Miguel (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1992-12-02)
    Article
    Open Access
    A comparative study at 2.45 GHz concerning both measurement and reconstruction parameters for planar and cylindrical configurations is presented. For the sake of comparison, a numerical model consisting of two nonconcentric ...
  • Quantitative images of large biological bodies in microwave tomography by using numerical and real data 

    Mallorquí Franquet, Jordi Joan; Joachimowicz, N.; Broquetas Ibars, Antoni; Bolomey, J. C. (Jean-Charles) (IEE-INST ELEC ENG, 1996-11-01)
    Article
    Open Access
    A new inverse microwave imaging algorithm is presented which has the ability to obtain quantitative dielectric maps of large biological bodies. By using a priori information, obtained with a first order algorithm, the final ...
