Magnetic particle imaging (MPI) ndi njira yatsopano yojambulira yomwe imatha kujambula zithunzi zowoneka bwino ndikusunga mawonekedwe osasokoneza azinthu zina zamakono monga kujambula kwa maginito (MRI) ndi positron emission tomography (PET). Imatha kutsata malo ndi kuchuluka kwa ma superparamagnetic iron oxide nanoparticles osatsata chizindikiro chilichonse chakumbuyo.

MPI imagwiritsa ntchito mawonekedwe apadera, amkati mwa nanoparticles: momwe amachitira pamaso pa maginito, ndi kuzimitsa kwamunda. Gulu lapano la nanoparticles lomwe limagwiritsidwa ntchito mu MPI nthawi zambiri limapezeka pamalonda a MRI. Ma tracer apadera a MPI akupangidwa ndi magulu ambiri omwe amagwiritsa ntchito chitsulo chachitsulo chozunguliridwa ndi zokutira zosiyanasiyana. Otsatirawa amatha kuthetsa zopinga zomwe zilipo posintha kukula ndi zinthu za nanoparticles zomwe zimafunikira ndi MPI.

Magnetic Particle Imaging amagwiritsa ntchito geometry yapadera ya maginito kuti apange dera laulere (FFR). Mfundo yovutayi imayendetsa njira ya nanoparticle. Izi ndizosiyana kwambiri ndi MRI physics pomwe chithunzi chimapangidwa kuchokera kumunda wofanana.
