Covduab intensifieryug hauv xyoo 1950 thiab yog ib yam khoom zoo heev.Nws zoo nkaus li xaus keeb kwm ntawm kev tshuaj ntsuam duab.Nws ua rau X-ray fluoroscopy koob tshuaj txo qis heev nyob rau lub sijhawm ntawd, qhov yooj yim ntawm tus kws kho mob tau zoo heev, thiab tus neeg mob thiab cov kws kho mob tau txais kev tiv thaiv ntau dua.
Ib yam li ntawd, nrog rau txoj kev loj hlob ntawm cov cuab yeej technology, cov duab intensifiers tau los txog niaj hnub no, thiab lawv tau maj mam nkag mus rau cov laus, thiab txoj hmoo ntawm kev hloov tau ntev tau teem tseg.Nrog rau kev tawg ntawm ntau yam duab dynamic duab technologies, duab intensifier imaging technology yog maj tshem tawm.
Niaj hnub no, kuv yuav tsis cherish lub cim xeeb ntawm daim duab intensifier ntawm no, tab sis tsuas yog txheeb xyuas vim li cas cov duab intensifier raug tshem tawm nrog txhua tus.Kuv xav tias muaj qee qhov laj thawj tseem ceeb:
Ua ntej: daim duab hom yog me me, thiab nws yog ib qho yooj yim kom nco thiab misdiagnose.
Raws li tuaj yeem pom los ntawm daim duab hauv qab no, sab laug yog ib qho duab tsim los ntawm cov duab augmentation ntawm tag nrho cov plab hnyuv siab raum, uas tuaj yeem tsuas muaj ib feem ntawm cov tshuaj ntsuam xyuas hauv ib lub thav duab;sab xis yog tam sim no mainstream loj-scale imaging, uas muaj peev xwm muaj tag nrho Cov chaw soj ntsuam tag nrho ntawm lub plab zom mov yuav yooj yim dua rau kev soj ntsuam thiab kuaj mob.
Nyob rau hauv ib txwm muaj xwm txheej, thaum siv kev sib piv ua kev xav tau, ua raws li kev soj ntsuam ntawm tus neeg saib xyuas kev sib txawv, yog li ua kom muaj qhov zoo tshaj plaws ntes lub qhov txhab, tab sis rau kev tshuaj xyuas nrog tus neeg saib xyuas qhov sib txawv nrawm nrawm, nws yooj yim rau Cov cuab yeej tsis tuaj yeem khaws nrog lub zog, yog li nws tsis tuaj yeem pom.Piv txwv li, nyob rau hauv esophagography, nws yog ib qho yooj yim los tshwm sim qhov tshwm sim ntawm qhov sib txawv nce thiab dislocation ntawm contrast agent.
Daim duab me me tau dhau los ua qhov laj thawj tseem ceeb heev rau kev txwv kev txhim kho cov duab augmentation.Yog li, nws puas tuaj yeem ua tus duab ntxoov ntxoo loj dua?Qhov tseeb, nws tuaj yeem pom los ntawm lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm tus duab ntxoov ntxoo nce ntxiv tias nrog kev nce ntawm cov duab duab, qhov ntim ntawm tag nrho cov duab ntxoov ntxoo kuj hloov pauv ntau, thiab thaum kawg nws tsis tuaj yeem siv hauv kev sib koom tes nrog tag nrho lub tshuab, yog li ntawd. Tam sim no tus duab ntxoov ntxoo loj tshaj plaws tuaj yeem ncav cuag 12 ntiv tes, feem ntau siv Cov tseem ceeb yog 7/9inch.
Qhov thib ob, nws yog ib qho yooj yim rau distorted thiab distorted, thiab nws yog ib qho yooj yim kom tsis nco qab thiab misdiagnosed.
Vim nws txoj hauv kev ua haujlwm, cov duab intensifiers muaj feem cuam tshuam thiab distortion.Distortion Muaj ob lub ntsiab ntawm distortion: ib qho yog ncig sib npaug geometric distortion;Lwm qhov yog asymmetrical, feem ntau hu ua S-distortion.
Yog vim li cas rau qhov geometric distortion yog tias qhov projection ntawm X-ray duab mus rau ib qho chaw nkhaus ua rau cov duab loj dua ntawm ib qho khoom ntawm lub dav hlau nkag ntawm cov npoo ntawm lub vijtsam input tshaj qhov nruab nrab.Qhov kev tsis sib haum xeeb no muaj feem xyuam nrog lub geometry ntawm lub vijtsam nkag thiab qhov hloov pauv ntawm X-ray qhov chaw.txoj hauj lwm-dependent, yog li nws yog hu ua geometrical distortion.Lub lens nrog qhov tsis zoo distortion yuav ib feem them rau qhov zoo distortion vim qhov curvature ntawm lub vijtsam input, yog li txo qhov kev cuam tshuam tag nrho ntawm cov duab tso zis, tab sis qhov distortion tsis tuaj yeem zam.
Lwm hom distortion yog hu ua S-distortion, uas yog vim tus yam ntxwv S-zoo li tus duab ntawm cov khoom rectilinear, ib tug tshwm sim los ntawm kev cuam tshuam los ntawm lub ntiaj teb no magnetic teb los yog stray magnetic teb los ntawm ib puag ncig cov khoom.
Nws yog precisely vim hais tias ntawm distortion thiab distortion (raws li qhia nyob rau hauv daim duab hauv qab no) tias nws cuam tshuam nrog kev soj ntsuam soj ntsuam ntawm cov duab X-ray, uas tej zaum yuav yooj yim ua rau tsis tau kuaj thiab misdiagnosis.
Thib peb, cov duab zoo sib xws yog qhov tsawg, uas yooj yim rau kev nco thiab tsis pom zoo.
Tam sim no, dynamic ntau yam ntawm mainstream X-ray duab yog 14-ntsis los yog 16-ntsis, thaum lub dynamic ntau yam ntawm cov duab intensifier tsuas yog 10-ntsis.Nyob rau hauv lwm yam lus, dynamic ntau yam ntawm cov khoom siv tam sim no dynamic imaging khoom yog 16 zaug los yog 32 npaug ntawm cov yeeb yaj kiab.
Lub dynamic ntau yam txawv, thiab qhov tshwm sim yog raws li qhia hauv daim duab hauv qab no.Lub dynamic ntau ntawm sab laug yog pom tseeb ntau dua qhov ntawm sab xis, yog li qhov zoo thiab xim ntawm cov duab sib txawv heev.
Daim duab ntawm tus duab ntxoov ntxoo nce yog qhia hauv daim duab hauv qab no.Qhov dynamic ntau ntawm 10 cov khoom yuav tsis muaj txiaj ntsig hauv kev soj ntsuam cov kab mob nrog qhov sib txawv me me hauv cov duab ntom ntom, tshwj xeeb tshaj yog nyob rau hauv exudative thiab diffuse imaging pathological hloov xws li thaum ntxov SARS lub ntsws hloov.Nws tsis tuaj yeem kuaj xyuas kom raug, uas tuaj yeem yooj yim ua rau kev kuaj mob tsis raug thiab tsis pom zoo.
Technology hloov nrog txhua hnub dhau mus, thiab cov khoom hloov pauv yog lub ntiaj teb co.Duab intensifierstau dhau los ntawm lawv cov hnub ci ntsa iab thiab tau mus txog qhov kawg ntawm lawv lub neej.Yuav tsum muaj kev sib tw ntau dua hauv kev kuaj pom kev kho mob.Nco ntsoov yav dhau los thiab tos ntsoov rau yav tom ntej, txhua yam yuav dhau los ua keeb kwm.
Yog tias koj txaus siab rau peb cov khoom, txais tos los tham.
