Abstract :
Confocal microwave imaging (CMI) is a recently introduced method of breast tumor detection that utilizes techniques adapted from ground penetrating radar for mine detection. Initial feasibility studies performed with simulated data indicate that CMI is a promising method for tumor detection and localization. In this paper, we explore the detection ability and resolution of the system. The detection ability is examined by imaging tumors of small diameter, while resolution is investigated by imaging 2 tumors located in dose proximity. Results indicate that tumors located 3 cm deep and of 3-mm diameter and greater are detected. Resolution is estimated to be 1 cm for two 6-mm diameter tumors.
