Imaging for Detecting Breast Cancers Using UWB Radar Technology

Ultra wide band (UWB) microwave imaging has recently been proposed for detecting small malignant breast tumors and is expected to detect breast tumors with safety, comfort and precision for high resolution of UWB pulse. In this paper, we propose a new imaging method that uses circle approximation to detect the cancer in order for automatically detection without doctors’ analysis. Our proposal method measures a radius of a cancer, and decides the center point of cancers on the circumference. The method is simulated by 2D FDTD method. As the result, our method showed higher detection accuracy of a center position and a radius of a circle formed cancer than conventional method.
