Outline of Final Research Achievements

Breast cancer incidence and mortality increase every year. It becomes important to detect early stage tumors for healing. We focus on the advances in biological measurement, such as, imaging for breast cancer detection use of the ultrashort-pulse radar techniques. We have developed the broadband antennas for the measurement system. We have improved the system by reduction of the unnecessary reflected signal, and we have also performed the imaging diagnostics using confocal microwave imaging for the breast cancer detection using phantom model which is approximate to the actual breast tissue. We have detected the dimension of the target as the tumor is 3 x 3 x 2.5 [mm], which is located at around 10 mm depth from the top of the phantom model.
