X-rays: Lub Qhov Muag Ntxiv Ntawm Tib Neeg

X-rays: lub qhov muag txuas ntxiv ntawm tib neeg

X-rays ua tau dab tsi? Piv nrog rau cov cuab yeej tshawb fawb loj no, tib neeg paub ntau dua nrog kev kuaj X-ray ua hauv tsev kho mob. Interestingly, qhov kev tshawb pom ntawm "X-rays" ntau dua 100 xyoo dhau los yog qhov tsis sib xws, thiab nws qhov kev tshawb pom tau ua rau muaj kev hloov pauv rau kev kuaj mob thiab kev nyab xeeb.

Thaum lub Kaum Ib Hlis 8, 1895, tus naas ej German physicist Wilhelm Konrad Roentgen tau npaj los kawm txog lub peev xwm nkag mus ntawm cathode rays. Roentgen thawj zaug rov ua qhov kev sim yav dhau los. Txawm li cas los xij, txhawm rau kom tsis suav nrog kev sib cuam tshuam ntawm cathode rays thiab lub ntiaj teb sab nraud, Roentgen nruj nreem kaw lub cathode ray tube nrog cov duab los qhia dub thiab cov ntawv ci, kom pom lub teeb pom kev hauv lub raj yuav tsis xau tawm ntawm lub raj.

(William Conrad Roentgen)

Lub chaw kuaj mob yog ib chav tsaus nti nrog ua tiav shading. Hauv kev sim txuas nrog lub zog hluav taws xob high-voltage, Roentgen tau pom tias lub vijtsam fluorescent nyob deb li ib 'meter' emissions faint flash. Thaum lub hwj chim raug txiav tawm, fluorescence ploj tam sim ntawd. Nws tau xaiv ntau yam khoom siv rau cov teeb meem, suav nrog nws tus ntiv tes. Roentgen tuav ib qho ntawm cov hlau lead ntawm nws tus ntiv tes ntiv tes thiab ntiv tes xoo thiab muab tso rau qhov chaw uas lub teeb dhau mus. Nws xav tsis thoob thaum pom ib daim duab ntawm nws tus ntiv tes rau ntawm cov hlau lead. Cov pob txha ntawm tus ntiv tes tsim cov duab ntxoov ntxoo tsaus dua li cov ntaub so ntswg nyob ib puag ncig.

Tom qab sim thiab ua yuam kev, Roentgen tau ntseeg tias qhov no yog ib hom kab hluav taws xob tshiab uas tseem tsis tau lees paub, thiab nws qhov xwm txheej tsis meej rau ib ntus, yog li nws tau hu ua "X-ray". Tsis ntev, Mrs. Roentgen tuaj rau hauv chav kuaj, thiab nws lub nplhaib hnav ntiv tes tau X-ray, tawm hauv daim duab keeb kwm.

Vim yog qhov kev tshawb pom no, Roentgen tau txais thawj Nobel nqi zog hauv Physics hauv xyoo 1901. Nyob rau hauv kev hwm ntawm Roentgen, X-rays yog hu ua Roentgen rays.

X-rays tiag tiag yog luv-wavelength electromagnetic tsis, nrog ib tug wavelength ntawm li 0 01--10 nanometers. Vim nws qhov luv wavelength thiab siab zog, nws tuaj yeem yooj yim dhau los ntawm cov duab los qhia, cov leeg nqaij thiab lwm yam ntaub so ntswg, tab sis tuaj yeem thaiv los ntawm cov khoom ntom ntom xws li hlau thiab pob txha. Yog li ntawd, X-rays yuav siv tau rau fluoroscopic imaging nyob rau hauv cov tshuaj, uas yog siv los soj ntsuam cov kab mob. lus txhais tau tias. Thaum X-rays nrog qhov tshwj xeeb penetrability yog siv los ua haujlwm rau tib neeg lub cev, cov duab ntawm cov qauv anatomical ntawm cov ntaub so ntswg thiab cov kabmob hauv lub cev tuaj yeem tau txais, yog li yooj yim muab cov ntaub ntawv tseem ceeb uas xav tau rau kev kuaj mob ntawm cov kab mob. Tsis tas li ntawd, thaum X-rays irradiated rau lub cev lom, cov kab mob lom tuaj yeem cuam tshuam, rhuav tshem lossis txawm tias necrotic, uas ua rau muaj ntau yam kev hloov pauv ntawm lub cev, kab mob thiab biochemical hauv lub cev.

X-rays yog lub qhov muag txuas ntxiv ntawm tib neeg, ua rau tib neeg pom lub ntiaj teb microscopic thiab cov qauv sab hauv uas pom tsis tau ntawm qhov muag liab qab. Ntxiv rau cov ntawv thov hauv kev kho mob, X-rays kuj tau siv dav hauv kev tsom xam cov qauv siv lead ua thiab hauv kev lag luam.
