Discovery ntawm MRI

Lub hauv paus ntawm lub cev ntawm magnetic resonance imaging (MRI) yog qhov tshwm sim ntawm nuclear magnetic resonance (NMR). Txhawm rau tiv thaiv lo lus "nuclear" los ntawm kev ua rau tib neeg ntshai thiab tshem tawm txoj kev pheej hmoo ntawm hluav taws xob hluav taws xob hauv NMR kev soj ntsuam, lub zej zog kev kawm tam sim no tau hloov pauv nuclear magnetic resonance rau magnetic resonance (MR). Qhov tshwm sim MR tau tshawb pom los ntawm Bloch ntawm Stanford University thiab Purcell ntawm Harvard University hauv xyoo 1946, thiab ob leeg tau txais txiaj ntsig Nobel nqi zog hauv Physics hauv xyoo 1952. Xyoo 1967, Jasper Jackson thawj zaug tau txais MR cov cim ntawm cov ntaub so ntswg nyob hauv cov tsiaj. Xyoo 1971, Damian ntawm State University of New York hauv Tebchaws Meskas tau hais tias nws muaj peev xwm siv qhov tshwm sim ntawm magnetic resonance los kuaj mob qog noj ntshav. Nyob rau hauv 1973, Lauterbur siv gradient magnetic teb los daws qhov teeb meem ntawm spatial positioning ntawm MR signals, thiab tau txais thawj ob-dimensional MR duab ntawm ib tug qauv dej, uas nteg lub hauv paus rau daim ntawv thov ntawm MRI nyob rau hauv kev kho mob teb. Thawj daim duab magnetic resonance ntawm tib neeg lub cev tau yug los hauv 1978.

Xyoo 1980, MRI scanner rau kev kuaj mob tau tsim tiav, thiab kev siv tshuaj kho mob tau pib. Lub International Sib Nqus Resonance Society tau tsim tsa hauv xyoo 1982, ua kom nrawm rau daim ntawv thov ntawm cov cuab yeej tshiab no hauv kev kuaj mob thiab kev tshawb fawb txog kev tshawb fawb. Xyoo 2003, Lauterbu thiab Mansfield koom ua ke yeej Nobel nqi zog hauv Physiology lossis Tshuaj hauv kev lees paub ntawm lawv qhov kev tshawb pom loj hauv kev tshawb fawb magnetic resonance imaging.
