Abstract:

The radar based UWB microwave imaging techniques have shown great potential for the localization of embedded dielectric targets in breast phantoms [1], [2]. In practical UWB microwave imaging systems, antennas play a key role in determining the characteristics of the received signals. The antennas behave as spatial-temporal filters as they have to radiate narrow pulses and thus the radiated signal may be distorted. Besides, the multipath effects and dispersion can also affect the reconstruction process. With this aim, in this paper, we investigate the effects of UWB antenna array on the image reconstruction for early stage breast cancer detection. A full-scale radar based microwave imaging system was reported in the literature that employed a small slot antenna with copper cage that was positioned into a hemispherical array to illuminate the breast [1]. Different types of horn antennas were also investigated for breast imaging [2], [3]. In this paper, we investigate the problem of breast tumor detection in an inhomogeneous breast phantom using a Vivaldi antenna array. We first investigate the experimental UWB characterization of the prototype-Vivaldi antenna element. Later, we perform FDTD simulations with a 7-element Vivaldi antenna array that is placed in a semi-circle arc around the numerical 3-D breast phantom. We employ the time-of-arrival calibration [6] and use the signal processing methods to reconstruct suspicious regions to localize the presence of tumor. We present results on image reconstruction using FDTD simulations. © 2012 IEICE.
