X-ray tshuaj xyuas tshuab cia siab ntau rau lawv cov cuab yeej tshawb nrhiav thiab algorithms thaum sib txawv ntawm cov hlau thiab cov khoom txawv teb chaws. Piv txwv li, cov khoom siv hlau (nrog rau cov khoom siv hlau ntes, cov khoom siv hlau nplaum, cov khoom siv hlau nplaum, cov khoom siv hlau nplaum, cov khoom siv hlau nplaum, thiab lwm yam) feem ntau siv cov ntsiab lus ntawm electromagnetic induction los ntes cov khoom txawv teb chaws hlau. Thaum ib qho khoom siv hlau nkag mus rau qhov chaw kuaj pom ntawm lub ntsuas hlau, nws cuam tshuam qhov sib npaug ntawm cov hlau nplaum tsim los ntawm lub transmitter thiab receiver, tsim lub teeb liab hloov ntawm lub receiver uas ua rau lub tswb thiab qhia tias muaj cov khoom txawv teb chaws hlau.
Txawm li cas los xij, rau cov khoom siv txawv teb chaws uas tsis yog xim hlau xws li pob zeb, iav, pob txha, yas, thiab lwm yam, cov khoom siv hlau tsis tuaj yeem ntes lawv ncaj qha. Hauv qhov no, lwm hom kev kuaj lub cev txawv teb chaws, xws li X-ray kuaj tshuab (tseem hu ua X-ray txawv teb chaws lub cev tshuaj xyuas tshuab lossis X-ray txawv teb chaws lub cev tshuaj xyuas tshuab) yuav tsum tau ua qhov kev tshuaj xyuas.
X-ray tshuaj xyuas lub tshuab siv lub peev xwm nkag mus ntawm X-rays los txheeb xyuas thiab paub qhov txawv ntawm cov hlau thiab cov hlau tsis yog hlau txawv teb chaws hauv cov khoom los ntawm kev ntsuas qhov degree ntawm attenuation ntawm X-rays tom qab nkag mus rau cov khoom soj ntsuam, thiab sib txuas cov duab ua technology. X-rays tuaj yeem nkag mus rau feem ntau cov khoom tsis yog xim hlau, tab sis muaj zog attenuation tshwm sim thaum ntsib cov khoom siv high-density xws li hlau, yog li ua kom pom qhov sib txawv ntawm daim duab thiab ua kom pom tseeb ntawm cov hlau txawv teb chaws lub cev.
Yog li ntawd, qhov sib txawv ntawm cov hlau thiab cov khoom txawv teb chaws nyob rau hauv txawv teb chaws lub cev detectors txawv nyob ntawm seb cov cuab yeej siv thiab algorithm siv. Cov khoom siv hlau feem ntau yog siv los kuaj xyuas cov khoom txawv teb chaws hlau, thaum lub x-ray detectors muaj peev xwm ntes tau ntau yam khoom txawv teb chaws, ob qho tib si hlau thiab tsis yog xim hlau, ntau dua.
Tsis tas li ntawd, raws li thev naus laus zis txuas ntxiv mus, qee qhov kev kuaj xyuas lub cev txawv teb chaws kuj tseem tuaj yeem siv kev sib txuas ntawm ntau yam kev tshawb nrhiav thev naus laus zis kom ua tiav ntau qhov tseeb thiab kev tshawb nrhiav ntau yam ntawm txawv teb chaws lub cev. Piv txwv li, qee cov khoom siv tuaj yeem ua ke ob qho tib si kev tshawb nrhiav hlau thiab X-ray nrhiav kom muaj peev xwm txhim kho qhov raug thiab kev ntseeg tau ntawm kev tshuaj xyuas.
