High-Resolution Laser-Assisted Magnetic Nanoparticle Imaging Using a High-TC SQUID Magnetometer

A new type of magnetic nanoparticle imaging (MPI) system has been proposed and developed. The spatial resolution of MPI systems is generally determined and limited by the size of the magnetic sensors used and the magnetic properties of the nanoparticles detected. Here, high-resolution imaging of mag...
