Hoton barbashi na Magnetic (MPI) wani sabon yanayin hoto ne tare da yuwuwar ɗaukar hoto mai ƙima yayin riƙe yanayin da ba shi da haɗari na wasu halaye na yanzu kamar su resonance magnetic (MRI) da tomography emit positron (PET). Yana iya bin diddigin wuri da yawa na nanoparticles superparamagnetic iron oxide nanoparticles ba tare da bin diddigin siginar baya ba.

MPI yana amfani da keɓaɓɓun, abubuwan ciki na abubuwan nanoparticles: yadda suke amsawa a gaban filin magnetic, da kuma kashe filin daga baya. Ƙungiyar nanoparticles na yanzu da ake amfani da su a MPI galibi ana samun kasuwanci don MRI. Masu binciken MPI na musamman suna cikin ci gaba ta ƙungiyoyi da yawa waɗanda ke amfani da murfin baƙin ƙarfe-oxide wanda yashafi daban-daban. Waɗannan masu bin diddigin za su warware matsalolin yanzu ta hanyar canza girman da kayan nanoparticles zuwa abin da MPI ke buƙata.

Hoto Barbashi na Magnetic yana amfani da geometry na musamman na magnetic don ƙirƙirar yanki kyauta (FFR). Wannan mahimmin batu yana sarrafa alƙawarin nanoparticle. Wannan ya sha bamban da kimiyyar lissafi na MRI inda aka ƙirƙiri hoto daga filin daidaitawa.
