In this paper, an efficient and robust image reconstruction algorithm for breast cancer detection by ultra-wide band microwave imaging system is presented. To test the efficacy of this approach, a three-dimensional model of the breast organisms is numerically carried out by the FDTD method. The PML absorption boundary condition is developed in the computer system. The norm constrained capon beamforming...
A study of the Ultra-Wideband (UWB) microwave imaging via the finite difference time domain method (FDTD) with perfectly matched layer absorption boundary condition (PML ABC) for detecting the early malignant tumor in the human breast is presented. In this study, the principle of the microwave imaging is presented in detail. The tumor detection in a two dimensional breast model with dispersive characteristic...
Ultra-wideband (UWB) microwave imaging is a very promising method for the early breast cancer detection physically based on the large contrast of electromagnetic parameters between the malignant tumor and the normal breast tissues. In this study, the tumor detection in a two dimensional breast model with dispersive characteristic properties of the breast organisms is carried out numerically by the...
A study on the Ultra-Wideband (UWB) microwave imaging for detecting the malignant tumor in the human breast is presented. The planer two-dimensional breast model is used to simulate the microwave propagation in the breast by the Finite Difference Time Domain method (FDTD). The confocal algorithm is employed to reconstruct the breast image to show the tumor information involving its size and the location...
