    UCT Seminar: Prof Karl Schilcher, University of Mainz, Germany

    Dear all,

    on Wednesday, Prof Karl Schilcher, University of Mainz, Germany, will give a presentation

    Electrical Impedance Tomography and Breast Cancer Diagnosis
    Breast cancer is presently routinely detected by palpation, by X-ray mammography and by ultrasound imaging. These classical diagnostic methods, however, yield rather unspecific results. Research is therefore aimed at developing alternatives imaging techniques to diagnose breast cancer more accurately and earlier. One approach is to make use of electrical impedance tomography (EIT). As the conductivity of malign tissues is up to four times higher than that of healthy tissues, imaging the electrical properties of breast tissues will yield important information which can improve the specificity of the diagnosis. However, progress in medical applications of EIT has so far been seriously hampered by non-controllable effects of the skin-electrode contact impedance. In Mainz a new EIT imaging system is being developed which eliminates such effects. These modifications require new electronic hardware and a new mathematical reconstruction algorithms based on an alternative boundary value problem. In this talk, the Mainz EIT System is introduced together with the essential theoretical formalism. Results for synthetic data and salt water tank data are presented.
    when: Wed, 9 March 2011, 12:00 to 13:00
    where: Duncan Elliott Seminar Room, RW James Building

    All welcome!
