On the feasibility of multi-characteristic parameter imaging of tissues

Abstract

Ultrasound plays a crucial role in medical examination and treatment. Based on the different effects of tissues excited by focused ultrasound, a novel imaging method of being able to provide multi-characteristic information of tissue is explored. The principles of Acousto-electric (AE) effect and acoustic radiation force (ARF) are introduced respectively. The feasibility of obtaining multi-characteristic information of tissue by combining ultrasound modulated electrical impedance tomography (UMEIT) and acoustic radiation force impulse (ARFI) imaging is verified by theoretical analysis and simulation experiments. In addition, the preliminary system is proposed, and the reconstructed images confirm that this method is effective. This method is expected to provide much more information of tissue for diagnosis, and break the limitation of medical diagnosis from a single characteristic imaging to gain a result with high accuracy and efficient.
