Abstract
A system and method of imaging based on the interaction of ultrasonic pulses with a magnetic field. A static magnetic field is applied to an object having conductive properties. An ultrasound pulse is propagated into the object, and an electrical signal is detected which is related to the interaction of the ultrasound pulse local displacement of the conductive object and the magnetic field. Alternatively, and equivalently, an electrical pulse is propagated into the object, and an ultrasound signal is detected which is related to the interaction of the electrical pulse generated in the conductive object and the magnetic field. The acquired acoustic signals or the acquired electrical signals are processed to provide an image of the object. The acquired signals are dependent on local conductivity as well as local acoustic properties.
