Outline of Final Research Achievements

We developed a microwave mammography with the radar technology, and carried out clinical trials. While successful detecting early cancers with clear boundary, it is not possible to accurately reconstruct the shape of the cancer that occurred within the glandular tissue. To overcome this problem, it is essential to realize a microwave tomography that can reconstruct the relative dielectric constant and conductivity distribution in the breast. Suction fixed-type imaging sensor, multi-polarization for various scattering data collection, and use of commercial electromagnetic simulator for accurate modeling and analysis are effective means to reduce the size of the imaging sensor.
