Fast imaging method for microwave tomography
一种快速微波断层成像方法的研究*

To facilitate the spread of 2D microwave tomography for breast cancer detection, proposed a fast imaging method in the realization of the personal computer, which used a coarse mesh to image and locate the site of target firstly, then built a locally refined fine mesh to image. It conducted imaging experiments using simulated and experimental data for breast cancer detection. The imaging results demonstrate that compared with the conventional imaging method using an overall fine mesh, the proposed twice imaging method can remarkably reduce the complexity of computation and save time-cost up to 80% while the equivalent image quality of target can be obtained.
