Acousto-electric interaction signal (AEI signal) resulting from interaction of acoustic pressure wave and electrical current field has received recent attention in biomedical field for detection and registration of bioelectrical current. The signal is very of small value and brings about several challenges when detecting it. Several observations has been done in saline solution and on nerves and tissues under controlled condition that give optimistic indication about its utilization. Ultrasound Current Source Density Imaging (UCSDI) has been introduced, that uses the AEI signal to image the current distribution. This review provides an overview of the investigations on the AEI signal and USCDI imaging that has been made, their results and several considerations on the limitations and future possibilities on using the acousto-electric interaction signal.
由声压波与电流场相互作用产生的声电相互作用信号（AEI信号），近年来在生物医学领域受到关注，用于生物电流的检测与记录。该信号值非常小，检测时带来了诸多挑战。在生理盐水以及受控条件下的神经和组织上已进行了多项观察，这些观察对其应用给出了乐观的迹象。超声电流源密度成像（UCSDI）已被引入，它利用AEI信号对电流分布进行成像。本综述概述了对AEI信号和UCSDI成像的研究、其结果以及关于使用声电相互作用信号的局限性和未来可能性的若干思考。
