Ukufunyanwa kweMRI

Isiseko somzimba we-imaging resonance imaging (MRI) yinto ye-nuclear magnetic resonance (NMR). Ukuze kuthintelwe igama elithi "inyukliya" ekubangeleni uloyiko lwabantu kunye nokuphelisa umngcipheko wemitha yenyukliya ekuhlolweni kwe-NMR, uluntu lwangoku lwezemfundo luye lwatshintsha i-nuclear magnetic resonance ukuya kwi-magnetic resonance (MR). I-MR phenomenon yafunyanwa nguBloch weYunivesithi yaseStanford kunye nePurcell yeYunivesithi yaseHarvard ngo-1946, kwaye bobabini bawongwa ngeBhaso leNobel kwiFiziksi ngo-1952. Ngo-1967, uJasper Jackson waqala wafumana iimpawu ze-MR zezicubu eziphilayo kwizilwanyana. Ngowe-1971, uDamian weState University of New York eUnited States wenza isindululo sokuba kunokwenzeka ukuba kusetyenziswe imagnethi ukuxilonga umhlaza. Ngo-1973, uLauterbur wasebenzisa i-gradient magnetic fields ukusombulula ingxaki yokubeka indawo yeempawu ze-MR, kwaye wafumana umfanekiso we-MR wokuqala we-MR wemodeli yamanzi, owabeka isiseko sokusetyenziswa kwe-MRI kwintsimi yezonyango. Umfanekiso wokuqala wemagnethi womzimba womntu wazalwa ngo-1978.

Ngo-1980, iskena se-MRI sokuxilongwa kwezifo saphuhliswa ngempumelelo, kwaye ukusetyenziswa kweklinikhi kwaqala. I-International Magnetic Resonance Society yasekwa ngokusesikweni ngo-1982, ikhawulezisa ukusetyenziswa kobu buchwepheshe butsha ekuxilongweni kwezonyango kunye neeyunithi zophando lwezenzululwazi. Ngo-2003, uLauterbu kunye noMansfield ngokudibeneyo baphumelele iBhaso leNobel kwiPhysiology okanye iMedicine ekuqapheliseni oko bakufumanisileyo kuphando lokucinga ngemagnethi.
