ʻO ke kiʻi kiʻi ʻume mākenēki (MPI) kahi ʻano kiʻi hou me ka hiki no ke kiʻi kiʻekiʻe kiʻekiʻe ʻoiai e paʻa ana i ke ʻano noninvasive o nā ʻano hana o kēia wā e like me ke kiʻi resonance magnet (MRI) a me ka tomography emission positron (PET). Hiki iā ia ke nānā i kahi a me nā nui o nā nanoparticle hao hao superparamagnetic kūikawā me ka nānā ʻole ʻana i nā hōʻailona hope.

Hoʻohana ʻo MPI i nā ʻokoʻa, nā ʻaoʻao intrinsic o nā nanoparticle: pehea lākou e hana ai i ke alo o ka mākia mākia, a me ka huli aʻe o ka māla. ʻO ka hui o nā nanoparticle i kēia manawa e hoʻohana ʻia i MPI e loaʻa maʻamau no MRI. Ke hoʻomohala nei nā MPI kūikawā i ka hoʻomohala ʻia e nā hui he nui e hoʻohana i kahi kumu hao hao e hoʻopuni ʻia e nā uhi like ʻole. E hoʻonā ana kēia mau tracers i nā mea pale i kēia manawa ma ka hoʻololi ʻana i ka nui a me nā mea o nā nanoparticle i ka mea e koi ʻia e MPI.

Hoʻohana ka Magnetic Particle Imaging i kahi geometry kūikawā o nā magnetics e hana i kahi ʻāpana manuahi (FFR). Mālama kēlā kiko kiko i ka kuhikuhi o kahi nanoparticle. ʻOkoʻa loa kēia mai ka physics MRI kahi i hana ʻia ai kahi kiʻi mai kahi kahua like.
