Magnetic particle imaging (MPI) nuburyo bushya bwo gufata amashusho hamwe nubushobozi bwo gufata amashusho menshi cyane mugihe hagumanye imiterere idahwitse yubundi buryo bugezweho nka magnetic resonance imaging (MRI) na positron emission tomografiya (PET). Irashoboye gukurikirana ahantu hamwe nubunini bwa superparamagnetic idasanzwe ya okiside nanoparticles idakurikiranye ibimenyetso byerekana inyuma.

MPI ikoresha ibintu byihariye, byimbere muri nanoparticles: uko bitwara imbere yumurima wa magneti, hanyuma bikazimya umurima. Itsinda ryubu rya nanoparticles rikoreshwa muri MPI mubusanzwe riraboneka kubucuruzi bwa MRI. Imashini zidasanzwe za MPI ziri gutezwa imbere nitsinda ryinshi rikoresha intoki ya fer-oxyde ikikijwe nimpuzu zitandukanye. Izi tracers zakemura inzitizi zubu muguhindura ingano nibikoresho bya nanoparticles kubisabwa na MPI.

Magnetic Particle Imaging ikoresha geometrie idasanzwe ya magnetique kugirango ikore umurima wubusa (FFR). Iyo ngingo yunvikana igenzura icyerekezo cya nanoparticle. Ibi bitandukanye cyane na fiziki ya MRI aho ishusho ikozwe mumurima umwe.
