Early Detection of Breast Cancer Using Microwave Imaging

Abstract

Microwave imaging for medical applications is mapping the electrical property distributions in the body which have been paid close attention for several years. Breast cancer detection with microwave imaging is based on the contrast in electrical properties of cancerous tissues compared to normal tissues. A previously designed PCMA antenna has been used here along with its enhanced version SCPCMA antenna. Both antennas have been used with a hemisphere shape breast phantom model consisting with two models; skin & fatty phantoms. The skin & fat tissue are used as a simulation for normal tissues, and muscle tissue as a simulation for malignant tissues or tumors. Simulation results shown improved results of SAR analysis in detecting more cases due to the higher values of max SAR for SCPCMA antenna as compared with PCMA antenna, and this is back to the fact that SCPCMA has higher gain compared to PCMA antenna.
