Background:

Acousto-Electric Interaction (AEI) is a phenomenon with potential for non-invasive imaging of biological tissue electrical conductivity.
Differences in electrical conductivity between healthy and pathological breast tissues suggest AEI's utility for breast tumor detection.
Imaging heterogeneous structures like the breast using AEI presents significant technical instrumentation challenges.

Purpose of the Study:

To present an experimental setup designed to overcome instrumentation challenges for Acousto-Electric Interaction (AEI) imaging.
To demonstrate the feasibility of AEI for imaging biological tissues, specifically addressing breast tumor detection.

Main Methods:

Development and testing of a novel experimental setup for Acousto-Electric Interaction (AEI) measurements.
Characterization of ultrasonic vibration potential (Debye effect) and AEI signals using the developed setup.

Main Results:

Successful recording and presentation of Acousto-Electric Interaction (AEI) signals.
Demonstration of the ultrasonic vibration potential (Debye effect).
Preliminary analysis indicating the potential to measure cavitation effects using the AEI technique.

Conclusions:

The presented experimental setup addresses key instrumentation challenges for applying AEI in complex biological structures.
AEI shows potential as a non-invasive method for detecting differences in tissue conductivity, relevant for breast tumor diagnosis.
Further research may explore AEI's capability for cavitation effect measurement and its diagnostic implications.
