Tus Inventor ntawm X-ray tshuab

Xyoo 1895, kev tshawb pom ntawm X-rays los ntawm German physicist Wilm Konrad Roentgen coj mus rau qhov tshwm sim ntawm cov cuab yeej kuaj mob tshiab siv los ntawm cov kws kho mob. Ob peb lub hlis tom qab nws pom X-rays, Russell Reynolds tau ua lub tshuab X-ray no. Qhov no yog ib lub tshuab X-ray qub tshaj plaws nyob hauv lub ntiaj teb, tso cai rau tib neeg los saib sab hauv ntawm tib neeg lub cev yam tsis muaj kev phais.
Keeb kwm kev loj hlob
Txij li xyoo 1895, X-ray kuaj thiab kho tshuab tau ua tiav sai, uas tuaj yeem muab faib ua cov theem hauv qab no:
(1) Ion X-ray raj theem (1895-1912)
Qhov no yog theem pib ntawm cov khoom siv X-ray. Lub sijhawm ntawd, cov qauv ntawm lub tshuab X-ray yog qhov yooj yim heev. Cov roj uas muaj txias cathode ion X-ray raj nrog kev ua haujlwm qis tau siv los ua kom muaj hluav taws xob siab los ntawm kev siv lub tshuab loj induction coil. Cov khoom siv hluav taws xob raug pom zoo tsis tau nruab nrog cov cuab yeej tswj kom raug. X-ray tshuab ntaus ntawv muaj peev xwm me me, tsis muaj kev ua haujlwm zoo, tsis muaj zog nkag mus, tsis pom cov duab pom tseeb, thiab tsis muaj kev tiv thaiv. Raws li cov ntaub ntawv sau tseg, kev noj cov duab X-ray pelvic xav tau lub sij hawm nthuav tawm ntawm 40-60 feeb. Txawm li cas los xij, tom qab thaij duab, tus neeg mob daim tawv nqaij raug hlawv los ntawm X-ray.
(2) Electronic X-ray raj theem (1913-1928)
Nrog rau txoj kev loj hlob ntawm electromagnetism, lub tshuab nqus tsev siab thiab lwm yam kev qhuab qhia, xyoo 1910, American physicist WD Coolidge tau luam tawm ib daim ntawv qhia txog kev ua tiav ntawm tungsten filament X-ray raj. Txij li thaum nws cov tswv yim siv nyob rau hauv 1913, nws biggest feature yog tungsten filament yog rhuab mus rau ib tug incandescent lub xeev los muab cov electrons xav tau rau lub raj tam sim no. Yog li ntawd, kev kho cov cua kub ntawm cov filament tuaj yeem tswj lub raj tam sim no, kom lub raj hluav taws xob thiab tam sim no tuaj yeem hloov kho ntawm nws tus kheej, uas yog qhov xav tau los txhim kho cov duab zoo.
Lub invention ntawm lim daim phiaj nyob rau hauv 1913 ib feem tshem tawm tawg ri niab rays thiab txhim kho cov duab zoo. Hauv xyoo 1914, lub tshuab hluav taws xob cadmium tungstate fluorescent tau tsim, uas tau pib siv X-ray fluoroscopy. Xyoo 1923, nws tau tsim dual tsom x-ray raj, uas daws qhov kev xav tau ntawm radiography. Lub hwj chim ntawm X-ray raj tuaj yeem ncav cuag ntau txhiab watts, thiab sab ntev ntawm lub teeb pom kev zoo tsuas yog ob peb millimeters, txhim kho cov duab X-ray zoo heev. Nyob rau tib lub sijhawm, maj mam thov cov neeg ua haujlwm sib txawv tau txuas ntxiv nthuav dav qhov kev kuaj mob ntawm X-ray. Nws tsis yog ib qho cuab yeej yooj yim rau kev ntes cov duab pob txha, tab sis tau dhau los ua qhov chaw kuaj mob tseem ceeb uas tuaj yeem kuaj xyuas cov kab mob plab, bronchi, cov hlab ntsha, ventricles, ob lub raum, zais zis, thiab lwm yam kev sib txawv (x-ray nqus me me. sib txawv) hauv tib neeg cov ntaub so ntswg thiab lub cev. Tib lub sijhawm, X-rays kuj tau pib siv rau hauv kev kho mob.
