qhov nkag mus ntawm X-ray beam hu ua X-ray zoo. … ib nrab nqi txheej, lub thickness ntawm absorbing khoom tsim nyog los txo cov X-ray siv mus rau ib nrab ntawm nws thawj tus nqi. HVL raug cuam tshuam los ntawm tus kVp thiab ntxiv pom hauv cov kab muaj txiaj ntsig.
Yuav ua li cas tswj kev nkag mus ntawm lub nqaj?
- Ua kom X-ray beam zoo ua rau ntau dua nkag mus rau X-ray beam -kVp yog thawj tswj ntawm x-ray beam zoo thiab yog li beam penetrability.
Dab tsi cuam tshuam rau beam zoo?
Beam zoo nyob ntawm: kVp, cov khoom siv thiab cov kab pom ua ntej tus neeg mob.
Yuav ua li cas cuam tshuam rau attenuation?
Cov yam ntxwv uas cuam tshuam rau kev txo qis yog cuam tshuam nrog qhov xwm txheej X-ray beam thiab cov khoom ntawm cov khoom siv hluav taws xob hla dhau. Cov yam tseem ceeb no suav nrog xwm txheej beam zog, thickness, atomic naj npawb thiab ceev ntawm cov khoom.
Ob yam dab tsi cuam tshuam rau beam zoo?
Yam cuam tshuam rau x-ray zoo suav nrog:
- peak voltage (kVp)
- voltage waveform: txo ripple nce qhov zoo.
- beam filtration: nce filtration nce zoo los ntawm beam hardening.
- anode khoom: photon zog nyob ntawm kev khi lub zog ntawm cov plhaub hauv cov khoom siv anode.
