  • Use of magnetic field of magnetic resonance imaging devices as the source of the magnetic field of electromagnetic transducers
    Patent number: 5131392
    Abstract: A magnetic resonance imaging device is used to provide the static magnetic field for transducers. The static magnetic field in combination with electric current pulses energize phased arrayed transducers to generate acoustic waves or motion. The transducers can be arranged in the magnetic resonance imaging device static magnetic field to focus acoustic shock waves for the disintegration of target calculi in extracorporeal shock wave lithotripsy. The magnetic resonance imaging device is also used for target localization and monitoring of the mechanical energy effects of the transducers. In further embodiments, the transducers include coils that are implantable within a subject body and can be moved in the magnetic resonance imaging device's static magnetic field.
