A Theoretical Model for Targeting Therapy With the Particles of the Paramagnetic Nanometers-iron Nuclide Guided by Outside Magnetic Field / 中国医学物理学杂志

ABSTRACT

A theoretical model for the magnetic forces on ferromagnetic drug particles in a guiding magnetic field is established with the consideration of the electromagnetic field theory. Our model shows that the ferromagnetic drug particles can concentrate on the targeted area with the guidance of the outside magnetic field. Both the distribution of the intensity of the guiding magnetic field and the forces on ferromagnetic drug particles are studied numerically. The theoretical results are in good agreement with the experimental results reported recently.
