To develop image logging technology, this paper studies array magnetoacoustic tomography with magnetic induction(MAT-MI) on the basis of contrasting the research of home and abroad. Through design, computer simulation and experiment studies on generating system of pulsed magnetic field, we demonstrated that the pulsed power supply can realize narrow width, high peak and repeat pulsed current with inductive load, then pulsed magnetic field is generated in the coil. Magnetoacoustic tomography with magnetic induction combines the technology of Electrical Impedance Tomography and ultrasonic imaging, it can provide an impedance image with good accuracy and high spatial resolution, the method has a good prospect of application and extension in geophysical prospecting, medical imaging and other fields.
