Xoo hluav taws xob duab yog a txoj hau kev txheej txheem, thiab duab kev tsim tawm yuav siv qhov chaw ib txwm muaj ntawm cov yeeb yaj kiab photosensitive, txawm hais tias ncaj qha xoo hluav taws xob duab yog ua ntau thiab ntau dua. Hauv nws daim ntawv feem ntau, X-ray duab yog kev coj ua zoo.

Hauv qhov no, Qhov Kev Tshaj Tawm txhais li cas hauv radiology?

Kev kwv yees hais txog txoj kev xoo hluav taws xob nqaj, zoo li xub, hla lub cev thaum tus neeg nyob hauv txoj haujlwm ntawd. Nco ntsoov, tus xub tuaj yeem hla dhau thiab ua haujlwm pem hauv ntej mus rau tom qab, rov qab rau pem hauv ntej, ib sab mus rau ib sab, thiab lwm yam.

Ntxiv mus, dab tsi yog kev xa duab? kis duab Txhawm rau tsim cov duab nrog xoo hluav taws xob, suav tomography (CT) kuaj, thiab tshuaj fluoroscopy, cov kws kho hluav taws xob xa kab teeb ntawm lub zog loj photons los ntawm lub cev qauv uas lawv tau kawm.

Tom qab ntawd, ib tus tuaj yeem nug, uas yog hom kev ntsuas hluav taws xob li cas?

Dab tsi yog thawj nqaj hauv radiology?

Thaum ua qhov raug, xoo hluav taws xob tawm ntawm lub raj raws li qhov paub tias yog thawj nqaj . Thaum lub thawj nqaj dhau los ntawm lub cev, qee qhov hluav taws xob tau nqus rau hauv cov txheej txheem hu ua attenuation.
