Helitaanka MRI

Saldhigga jireed ee sawir-qaadista magnetic resonance (MRI) waa ifafaalaha resonance magnetic nuclear (NMR). Si looga hortago ereyga "Nukliyeerka" inuu keeno cabsida dadka oo meesha laga saaro khatarta shucaaca nukliyeerka ee kormeerka NMR, bulshada tacliinta ee hadda jirta waxay bedeshay resonance nukliyeerka magnetka (MR). Dhacdada MR waxaa daahfuray Bloch oo ka tirsan jaamacadda Stanford iyo Purcell oo ka tirsan jaamacadda Harvard sannadkii 1946kii, waxaana labadooda la guddoonsiiyey abaalmarinta Nobel Prize ee Fiisigiska 1952. 1967, Jasper Jackson ayaa markii ugu horreysay helay calaamadaha MR ee unugyada noolaha ee xayawaanka. Sannadkii 1971-kii, Damian oo ka tirsan Jaamacadda Gobolka New York ee dalka Mareykanka ayaa soo jeedisay in ay suurtagal tahay in la isticmaalo ifafaale ka mid ah falcelinta magnet-ka si loo ogaado kansarka. Sanadkii 1973, Lauterbur wuxuu isticmaalay dhulal magnetic gradient si uu u xalliyo dhibaatada meelaynta boosaska ee calaamadaha MR, waxayna heshay sawirka MR ee ugu horreeya ee laba-geesoodka ah ee qaabka biyaha, taas oo aasaas u ah codsiga MRI ee goobta caafimaadka. Sawirkii ugu horreeyay ee magnetic resonance ee jirka bini'aadamka wuxuu dhashay 1978.

Sannadkii 1980-kii, iskaanka MRI ee lagu ogaanayo cudurrada ayaa si guul leh loo sameeyay, waxaana la bilaabay codsi caafimaad. International Magnetic Resonance Society waxa si rasmi ah loo aasaasay 1982, iyada oo dedejisay adeegsiga tignoolajiyadan cusub ee baadhitaanka caafimaadka iyo qaybaha cilmi-baarista sayniska. 2003, Lauterbu iyo Mansfield waxay si wada jir ah ugu guulaysteen abaalmarinta Nobel Prize ee Physiology ama Medicine iyagoo aqoonsanaya daahfurnaantooda waaweyn ee cilmi-baarista sawir-qaadista magnetka.
