Abstract:Cancer is the main killing disease and breast cancer is the most common tumor among women. Compared to other cancers, the survival rate in case of breast cancer is high when detected early. Therefore intense screening programs are initiated. The standard for detection of breast cancer is mammography, which has several disadvantages such as ionizing radiation, high false-positive and false-negative rates. Ultrasound or magnetic resonance imaging can be applied to find tumors too, but both are not suited for largescale screenings. Researchers at Dartmouth college have shown that ultra-wideband (UWB) can be a solution as a complementary method. However, the principles on which their prototype relies are not explicitly mentioned. Their applied frequency range of 300 MHz to 3 GHz is not the one ruled by the Federal Communications Commission (FCC) or European Telecommunications Standards Institute (ETSI). The FCC ruled that UWB has to operate roughly in the band of 3.1 to 10.6 GHz, whereas the European regulation is somewhat more limited. The aim of this master thesis is to experimentally verify whether medical imaging is possible at the frequencies ruled by the FCC for UWB, whereas the power limitation was not taken into account.
