Cov khoom siv kho vajtse ntawm lub tshuab kuaj xyuas kev ruaj ntseg suav nrog: (1) X-ray tiam maub los (2) X-ray detector (3) cov ntaub ntawv nrhiav tau (4) mechanical device (5) X-ray qhov chaw tsim hluav taws xob hauv cov duab ntawm kev lag luam tswj lub computer thiab cov cuab yeej tso saib yuav tsum xyuas kom meej tias cov hluav taws xob tsawg tsawg thaum nws nyob ze rau tus neeg teb xov tooj. Ua ntej, nws nyob ntawm seb lub hom ntawm X-ray qhov chaw xaiv los ntawm cov chaw tsim tshuaj ntsuam kev ruaj ntseg raws li lub teb chaws tus qauv, Thaum American Spellman ray qhov chaw siv thiab sab ntawm lub tshuab yog 5cm rau 10cm deb los ntawm lub tshuab nto ntawm lub tshuab soj ntsuam kev ruaj ntseg, cov ntaub ntawv tshawb pom los ntawm cov neeg ua haujlwm nrog cov cuab yeej tuav yog 0.1 μ Sv / h txog 0.2 μ Sv / h, thiab cov hluav taws xob ntau ntawm tib neeg lub cev rau hauv siab X -ray yog kwv yees li 1.1msv ib zaug, suav nrog 2msv rau lub taub hau CT, 8msv rau hauv siab CT, 10msv rau plab CT thiab 10msv rau pelvis CT. Tus nqi hluav taws xob ntawm lub tshuab kuaj xyuas kev ruaj ntseg zoo ib yam li qhov ntsuas hauv ib puag ncig ntuj, uas yog hais tias, tsis muaj hluav taws xob los ntawm sab ntawm lub tshuab siv lub teb chaws tus qauv X-ray qhov chaw. Qhov thib ob, X-ray kev ruaj ntseg tshuaj xyuas lub tshuab yuav tsum muaj kev ua haujlwm ntawm kev tshuaj xyuas txhua yam khoom uas tsis txaus ntseeg. Cov cuab yeej tsim nyog
Rau qhov kev ua haujlwm zoo li no, ua ntej ntawm tag nrho cov, nws nyob ntawm seb daim npav yuav khoom ntawm lub tshuab kuaj xyuas kev ruaj ntseg puas tuaj yeem sau cov duab siab, kom cov neeg saib xyuas kev ruaj ntseg tuaj yeem txheeb xyuas cov khoom txaus ntshai. X-ray cov ntaub ntawv acquisition system yog ib tug multi-channel cov ntaub ntawv nrhiav tau system siv nyob rau hauv lub teb ntawm dual lub zog X-ray duab, nrog rau cov detector analog teeb liab acquisition board (tom qab no hu ua analog board, hauv qab sab laug) thiab digital processing board (tom qab no xa mus. mus ua digital board, hauv qab txoj cai). Txhua lub rooj sib tham analog muaj 128 qhov chaw ntes, uas tuaj yeem siv los ua kom phim cov cuab yeej nrog 1.6 hli pixel qhov sib nrug. Txhua lub rooj tsav xwm digital tuaj yeem nruab nrog 32 lub rooj sib tham hauv feem ntau, thiab txhua qhov kev tshuaj xyuas kev ruaj ntseg tshuab tuaj yeem nruab nrog 3 lub rooj tsav xwm digital feem ntau, txhawb nqa cov ntaub ntawv tau txog li 12288 ntes channel 1.
