Magnetic particle imaging was introduced in 2005 as a new tomographic medical imaging modality and is still under development. Magnetic particle imaging determines the spatial distribution of magnetic nanoparticles by their interaction with an external excitation magnetic field. Therefore, there is no ionizing radiation dose in this trace-based modality. Magnetic nanoparticle imaging provides characteristics, including high spatial and temporal resolution, high sensitivity, expected from an ideal imaging method, and it is also an inherently quantitative method.
In this paper, the properties of magnetic fields and particles used in Magnetic particle imaging, as well as its applications are discussed.
