| 摘 要： | 利用电阻抗扫描技术,研究人体乳腺在疾病状态下电导参数随激励频率的变化规律,为进一步的乳腺疾病检查打下基础。获得了浸润性导管癌、瘤样增生和乳腺腺病等三种乳腺疾病的电导参数的频率特性曲线,并与病变周围正常组织进行了对比,可以得出病变组织具有与正常组织不同的频率特性,而且上述三种不同种类疾病的频率特性也各有差异。因此提示可以根据频率特性的特征,来辨别病变的种类。

| Abstract: | The rules of conductance parameters on diseased breast tissue,which change with the driven frequency,are studied by use of electrical impedance scanning.This work is intended to provide a basis for further examination of breast.We have obtained conductance parameters' frequency characteristic of three kinds of breast diseases,i.e.invasive ductal carcinoma,neoplastic hyperplasia,and mastopathia.And by comparison,we find that the frequency characteristic of the diseased breast tissues is different from that of the peripheral normal tissues,and the frequency characteristic shows differences among the three kinds of diseased breast tissues.So,we are able to identify the kind of breast disease by its frequency characteristic. |
