Outline of Final Research Achievements

The aim of this research is to develop an imaging system which can generate both ultrasound and electrical conductivity images for early detection of breast tumor. In this research, an electrical and ultrasonic imaging system which a thin film with sixteen electrodes was arranged on the surface of the commercial ultrasonic scanner was developed. In the simulation and the model experiment, the electrical conductivity distributions in the simple breast model including the tumor were reconstructed with and without the ultrasound image as the initial information. As results, it was presented that the proposed system was usefulness since the electrical conductivity distribution was clearly improved by using ultrasonic image although there were some problems should be solved for practical application.
