Integrable Magnetic Fluid Hyperthermia Systems for 3D Magnetic Particle Imaging

Nanotheranostics
Background: Combining magnetic particle imaging (MPI) and magnetic fluid hyperthermia (MFH) offers the ability to perform localized hyperthermia and magnetic particle imaging-assisted ther-mometry of hyperthermia treatment. This allows precise regional selective heating inside the body without invasive interventions.
