X-ray Imaging Principple

X-ray Imaging Principple

X-ray yog ib hom hluav taws xob hluav taws xob hluav taws xob, thiab nws muaj lub wavelength luv dua li pom lub teeb kom nws tuaj yeem nkag mus rau cov khoom thiab cov duab hauv cov qauv thiab thaj chaw hauv txoj kev tsis muaj kev cuam tshuam.

X-ray attenuation sib txawv nrog cov khoom ntom thiab muaj pes tsawg leeg

Thaum lub beam ntawm x-ray yog npaj rau ib yam khoom, raws li qhov ceev thiab muaj pes tsawg leeg ntawm cov chaw sib txawv ntawm cov khoom, ib tug variation ntawm x-ray xa los ntawm cov khoom yog ntes los ntawm detectors, thiab ces cov x-ray teeb liab yog. digitalized thiab reconstructed rau hauv ib tug 2-dimentional x-ray duab, uas qhia tag nrho cov superimposed lug nyob rau hauv cov khoom. Cov hauv qab no yog cov duab x-ray ntawm lub hnab nqa khoom:
