本文提出了一种新的随机微波方法的检测，定位和重建的电气特性的乳腺癌在一个简化的乳房体模。该方法是基于时间域数据的反演。通过定义一个合适的代价函数，然后使用一个有效的进化算法使之最小化，将问题转化为一个优化问题。选择的简化的三维乳房模型和现实的数字幻影的基础上磁共振图像（MRI）的数值模拟进行评估的方法的能力。所得到的结果表明，所提出的方法是能够重建的肿瘤状夹杂物的性质，以合理的准确度。
This paper presents a novel stochastic microwave method for the detection, location and reconstruction of electric properties of breast cancer in a simplifled breast phantom. The method is based on the inversion of time domain data. The problem is recast as an optimization one by deflning a suitable cost function which is then minimized using an e-cient evolutionary algorithm. Selected numerical simulations of a simplifled three dimensional breast model and a realistic numerical phantom based on magnetic resonance images (MRIs) are carried out to assess the capabilities of the method. The results obtained show that the proposed method is able to reconstruct the properties of a tumor-like inclusion to a reasonable degree of accuracy.
