Abstract:
A magnetic resonance imager (MRI) controllably propels at least one magnetic field responsive body within a subject. The MRI comprises a bore magnet producing an intense magnetic field sufficient to magnetically saturate the magnetic field responsive body. A magnetic field gradient generator is configured to apply variable magnetic gradients to at least a portion of the subject containing the magnetically-saturated body. A controller instructs the magnetic field gradient generator to acquire image data of the magnetically-saturated body within the subject and to apply a calculated magnetic gradient that will propel the magnetically-saturated body towards a target location in the subject. A tracking unit of the MRI provides position feedback information of the magnetically-saturated body within the subject.
