Abstract

Breast cancer has become the first killer of urban women , early diagnosis is of decisive significance to control and reduce the mortality rate of breast cancer patients , so the early diagnosis of breast cancer technology become a focus of breast cancer research at home and abroad . , Ultra-wideband microwave imaging detection of breast cancer because of its high image resolution and high imaging contrast increasingly important early breast cancer is expected to become a safe and practical means of routine testing . This article is based on a hemispherical breast model using the finite difference time domain method numerical simulation of breast cancer ultra-wideband microwave imaging solutions . According to the actual characteristics of the breast detection imaging , paper consider the transceiver antenna separation , in order to reduce the demanding requirements of the system design of the transceiver common ultra-wideband antenna , then , in this paper , to explore the detection antenna configuration program , and developed appropriate for the program of early breast cancer imaging confocal algorithm , imaging results . The results show that the program can effectively detect early breast cancer of less than 10mm in diameter . For early breast cancer detection imaging requirements , the paper also studied the coupling medium between ultra-wideband antenna with breast imaging resolution and the principle of selecting the coupling medium , pointed out that the use of a coupling medium dielectric constant higher than 9.0 the necessary high resolution can be obtained in the early detection of breast cancer ultra-wideband microwave imaging . Against the actual breast may exist in the different positions of a plurality of tumor hemispherical breast model for the arrangement of the transmitting and receiving antennas , and to try a \missing rate . In addition, we further explore the ultra-wideband microwave of ductal and lobular breast tissue with random inhomogeneities in early breast cancer diagnosis , imaging results show that proposed by the authors of this article ultra-wideband microwave early breast cancer diagnosis detection programs and confocal imaging algorithm in random non-uniformity of ± 10% of the breast tissue can still be effective imaging .
