Apparatus and method for imaging currents using nanoparticles and low-field magnetic resonance imaging (MRI)

摘要

A system and method for imaging in connection with electrical currents includes nanoparticles introduced into a region in which the electrical currents are present. A low-field magnetic resonance imaging (MRI) scanner detects an effect of a magnetic field generated by interaction of the nanoparticles with the electrical currents in the region. The MRI scanner operates at a magnetic field intensity below a level at which the nanoparticles would be magnetically saturated.
