Abstract：To propose a new ultrasonic -magnetoelectric imaging method with low frequency vibration , which is a dual modal func-tional imaging method combining acoustic and magneto -electric imaging methods .The basic principle of this method is to place a bio-logical tissue in a static magnetic field , and excite the tissue by a low frequency vibration to produce internal vibration .The elastic in-formation of the tissue can be obtained by detecting the shear wave by ultrasonic pulse echo method .The electrical conductivity infor-mation can be obtained by detecting the surface electrical signals .A test experiment was carried out using the QA phantom and copper wire.The experimental results showed that the experimental platform had feasibility and applicability .Then some preliminary experi-ments were performed which synchronously detected the elasticity and conductivity edge of the custom -made phantom .
