Acousto-Electric Interaction (AEI) is a physical phenomenon identified in the literature as potentially useful for imaging the electrical conductivity of biological tissues. AEI could lead to a non-invasive technique for detecting breast tumors, since the conductivity of pathological tissues differs significantly from the conductivity of healthy breast tissues. Applying AEI to image heterogeneous structures of the size of the breast represents a major technical challenge. We present in this paper an experimental setup designed to address the various instrumentation issues of AEI. Tests results are presented showing the ultrasonic vibration potential (also known as the Debye effect) and the AEI signals. A preliminary analysis of the AEI signal we recorded suggests that cavitation effects can be measured with this technique.
声电相互作用（AEI）是一种在文献中被认定为对生物组织电导率成像可能有用的物理现象。由于病理组织的电导率与健康乳腺组织的电导率有显著差异，AEI可能会带来一种检测乳腺肿瘤的非侵入性技术。将AEI应用于对乳房大小的异质结构进行成像面临着重大技术挑战。我们在本文中展示了一个旨在解决AEI各种仪器问题的实验装置。给出了测试结果，展示了超声振动电位（也称为德拜效应）和AEI信号。我们对记录的AEI信号进行的初步分析表明，可以用这种技术测量空化效应。
