Outline of Final Research Achievements

We have established the novel tomographic theory capable of visualizing materials as scatters using the signal of scattering wave, and developed the technology of microwave subsurface imaging for breast cancer. Heretofore, we have succeeded in the imaging of breast phantoms, pig breasts and human breast cancers, and made the essential improvement of element technologies. In this study, we have contributed to development of the array antenna module for the multi-static microwave imaging, measurements of dielectric properties on breast specimen, and novel scattering tomography theory for the degradation problem of spatial resolution due to the finite size of antenna. In near future, we have a plan to develop a product model of the microwave breast cancer imaging system and establish the basis of its breast cancer detecting in the viewpoint of condensed matter physics.
