摘　　要：以人体乳腺组织电阻抗特性为依据的乳腺电阻抗扫描成像技术的出现,为乳腺癌的早期检查与辅助诊断开辟了一个新的方向。人体乳腺组织的电阻抗特性反映了乳腺组织的病理生理状态,而对它的测量成为乳腺电阻抗扫描成像技术的前提和基础。主要讨论了人体乳腺组织电阻抗特性的测量方法、测量结果以及存在的问题,对乳腺电阻抗成像技术的应用前景进行了展望。Breast cancer is one of the most common malignant turnouts in women. It threatens the health and life of women. The imaging technology of breast electrical impedance scanning based on the dielectric properties of breast tissues develops a new aspect of early detection and auxiliary diagnosis of the breast cancer. The dielectric properties of human breast tissues reflect the pathological and physiological state of breast tissues and the measurement of these properties serves as the basis for electrical impedance scanning（EIS） technology. In this paper, the measurements and results of dielectric properties of human breast tissues are discussed, and the problems of measurement and the application perspective of the EIS are also explored.
