乳腺癌是妇女常见的恶性肿瘤，全世界每年约有120万妇女患乳腺癌，50万人死于乳腺癌。在西欧、北美等发达国家，乳腺癌发病率占女性恶性肿瘤首位。因此，及早的发现乳腺癌并对其进行治疗成为当务之急。目前诊断乳腺癌的常规手段是乳房X光造影技术（X－mammography），对早期乳腺癌检测率较低，且受检者有安全忧虑。

   我们所介绍的是一种以聚焦微波成像系统用于探测乳腺癌并使其图像生动再现的运算法则。为了测试这一方法的功效，我们在FDTD的模型之上发展出一个乳腺癌的三维空间生物超宽带微波成像系统。这一生物成像算法用于FDTD对于反馈信号的估算，得到微波成像从而明确地识别出癌变是否存在及其所在位置。这些仿真证明了这种新的方法对于早期乳房肿瘤探测及成像的可行性。

       The mammary glands cancer is a familiar malignant tumor of women，whole world every year is roughly to reach 120 ten thousand women get the mammary glands cancer, 50 myriad peoples die in the mammary glands cancer. Mammary glands cancer hair disease the rate occupy the female malignant tumor first Prosper the nation in Western Europe, North America...etc.

So early of detection mammary glands the cancer combine as to it's proceed the treatment become the urgent matter of the moment. The normal regulations means of the mammary glands cancer of current diagnosis is X－mammography. To earlier period mammary glands cancer examination the rate is lower, and accept to Examiner contain worried safety.

Its diagram that our what introduce is a kind of focuse the microwave resemble the system to used for to probe into the mammary glands cancer also make the calculation rule resemble the vivid emersion。For the sake of the test the effect of this method，We are in the FDTD model on develop to out a mammary glands cancer of  3D space living creature the breadth takes the wide microwave resemble the system。This whole life thing resemble the calculate way to used for the FDTD for return the signal's estimation，Get the microwave resemble from but clearly identify out the cancer to change if exsit and position of its place，These imitated the true proof this kind of new method for the earlier period breast the tumor probe into and like of possibility。
