Nyob rau hauv cov pa radiography, qhov sib txawv nyob ntawm seb qhov loj ntawm cov nplej, lub sij hawm ntawm kev loj hlob, qhov concentration thiab kub ntawm cov kev daws teeb meem, thiab tag nrho cov zaj duab xis. ceev.

Ib yam li ntawd, tib neeg nug, plaub yam dab tsi cuam tshuam rau qhov zoo ntawm qhov sib txawv radiographic?

PIB #132647

Lus nug Teb
Dab tsi cuam tshuam cov duab receptor (zaj duab xis) sib piv? Cov yam ntxwv ntawm cov yeeb yaj kiab thiab kev ua haujlwm
Dab tsi txiav txim siab qhov sib txawv? qhov loj, zoo, thiab attenuating yam ntxwv ntawm cov khoom raug irradiated
Qhov twg ntawm 2 qhov sib txawv ntawm qhov yuav tsum tau ua qauv? Duab receptor (film) sib piv

Qhov thib ob, dab tsi yog qhov tseem ceeb tswj hwm radiographic ceev? Ob peb yam tuaj yeem cuam tshuam txog kev muaj peev xwm ntawm kev kuaj mob hluav taws xob duab xws li kVp, lub sij hawm raug, mA, pom, collimation, daim phiaj, thiab hom ntawm txoj hauj lwm qhia ntaus ntawv.

Tom qab ntawd, ib tus tuaj yeem nug, vim li cas thiaj xav tau qhov sib txawv hauv daim duab radiographic?
