Txoj kev loj hlob ntawm cov tshuab computer niaj hnub no ua rau muaj kev vam meej ntawm kev kho mob digital imaging technology. Molecular imaging yog ib qho kev kawm tshiab uas tsim los ntawm kev sib txuas molecular biology nrog cov duab kho mob niaj hnub. Nws txawv ntawm classical kho mob imaging technology. Feem ntau, cov txheej txheem kev kho mob classical qhia txog qhov kawg ntawm cov kev hloov pauv ntawm molecular hauv tib neeg lub hlwb, kuaj pom qhov txawv txav tom qab hloov pauv anatomical. Txawm li cas los xij, kev kuaj pom molecular tuaj yeem kuaj pom cov kev hloov pauv hauv cov hlwb nyob rau theem pib ntawm cov kab mob los ntawm qee qhov kev sim tshwj xeeb los ntawm kev siv qee cov cuab yeej tshiab thiab cov tshuaj reagents yam tsis muaj kev hloov pauv anatomical, uas tuaj yeem pab cov kws kho mob nkag siab txog kev txhim kho ntawm cov neeg mob cov kab mob. Yog li ntawd, nws kuj yog ib qho cuab yeej pabcuam zoo rau kev tshuaj xyuas tshuaj thiab kev kuaj mob.
1. Kev nce qib ntawm cov thev naus laus zis thev naus laus zis thev naus laus zis
1.1Computer Radiography (CR)
CR thev naus laus zis sau X-rays nrog lub rooj tsav xwm duab, zoo siab rau cov duab board nrog lub laser, hloov cov teeb liab lub teeb tawm los ntawm cov duab board rau hauv kev sib txuas lus los ntawm cov cuab yeej tshwj xeeb, thiab thaum kawg cov txheej txheem thiab cov duab nrog kev pab ntawm lub computer. Nws txawv ntawm cov tshuaj hluav taws xob ib txwm siv nyob rau hauv uas CR siv IP tsis yog cov yeeb yaj kiab ua tus nqa khoom, yog li CR thev naus laus zis ua lub luag haujlwm hloov pauv hauv cov txheej txheem ntawm cov tshuaj hluav taws xob niaj hnub thev naus laus zis.
1.2 Direct Radiography (DR)
Muaj qee qhov sib txawv ntawm kev thaij duab xoo hluav taws xob ncaj qha thiab cov tshuab X-ray ib txwm muaj. Ua ntej, cov txheej txheem ntawm photosensitive imaging ntawm zaj duab xis yog hloov los ntawm kev hloov cov ntaub ntawv mus rau hauv lub teeb liab uas yuav tsum tau lees paub los ntawm lub computer los ntawm ib tug detector. Thib ob, siv cov haujlwm ntawm lub khoos phis tawj los ua cov duab digital, tag nrho cov txheej txheem yog kev ua haujlwm hluav taws xob tag nrho, uas muab kev yooj yim rau kev kho mob.
Linear radiography tuaj yeem muab faib ua peb hom raws li cov khoom sib txawv uas nws siv. Direct digital imaging, nws detector yog amorphous silicon phaj, piv nrog indirect zog hloov dua siab tshiab DR Nyob rau hauv spatial daws yog zoo dua; Rau indirect digital imaging, feem ntau siv detectors yog: cesium iodide, gadolinium oxide ntawm leej faj, cesium iodide / Gadolinium oxide ntawm leej faj + lens / optical fiber + CCD / CMOS thiab cesium iodide / Gadolinium oxide ntawm sulfur + CMOS; Duab intensifier Digital X yees duab system,
CCD detector tam sim no tau siv dav hauv cov kab mob plab hnyuv thiab cov kab mob angiography loj
2. Txoj kev loj hlob ntawm kev kho mob loj digital imaging technologies
2.1 Kev nce qib tshiab ntawm CR
1) Txhim kho cov duab kos duab. Cov khoom siv tshiab siv hauv cov qauv ntawm daim duab phaj zoo heev txo cov fluorescence tawg tshwm sim, thiab cov duab sharpness thiab nthuav dav kev daws teeb meem tau txhim kho, yog li qhov zoo ntawm cov duab tau zoo dua.
2) Txhim kho hom scanning. Siv kab scanning tshuab es tsis txhob ya qhov chaw scanning tshuab thiab siv CCD raws li cov duab sau, lub sij hawm scanning yog pom tseeb shortened.
3) Tom qab ua tiav software tau ntxiv dag zog thiab txhim kho. Nrog rau kev txhim kho ntawm computer technology, ntau manufacturers tau qhia ntau yam software. Los ntawm kev siv cov software no, qee qhov chaw tsis zoo ntawm cov duab tuaj yeem txhim kho tau zoo, lossis qhov poob ntawm cov duab nthuav dav tuaj yeem txo qis, kom tau txais daim duab ntau toned.
4) CR txuas ntxiv txhim kho nyob rau hauv cov kev taw qhia ntawm kev kho mob ua haujlwm zoo ib yam li DR. Zoo ib yam li kev ua haujlwm ntawm DR, CR tuaj yeem nruab ib tus nyeem ntawv hauv txhua chav radiography lossis kev khiav haujlwm console; Zoo ib yam li cov duab tsis siv neeg tsim los ntawm DR, cov txheej txheem ntawm kev tsim kho duab thiab laser scanning tau ua tiav.
2.2 Kev tshawb fawb kev kawm ntawm DR Technology
1) Kev nce qib hauv cov duab digital ntawm non-crystalline silicon thiab amorphous selenium ca vaj huam sib luag ntes. Qhov kev hloov pauv tseem ceeb tshwm sim hauv cov qauv ntawm cov qauv siv lead ua, raws li kev tshawb fawb, koob thiab columnar qauv ntawm amorphous silicon thiab amorphous selenium tuaj yeem txo cov xoo hluav taws xob tawg, yog li ntawd lub sharpness thiab clarity ntawm daim duab zoo dua.
2) Kev nce qib hauv cov duab digital ntawm CMOS ca vaj huam sib luag ntes. Cov kab fluorescent txheej txheej ntawm CM0S lub ntsuas ntsuas lub tiaj tus tuaj yeem tsim cov kab fluorescent sib raug rau qhov xwm txheej X-ray beam, thiab cov teeb liab fluorescent raug ntes los ntawm CMOS nti thiab thaum kawg nthuav dav thiab ua tiav. Yog li ntawd, qhov kev daws teeb meem spatial ntawm M0S planar detector yog siab li 6.1LP / m, uas yog lub ntsuas qhov ntsuas siab tshaj plaws. Txawm li cas los xij, qhov kev ntsuas qeeb qeeb ntawm lub kaw lus tau dhau los ua qhov tsis muaj zog ntawm CMOS ca vaj huam sib luag ntes.
3) CCD digital imaging tau ua tiav. CCD cov duab hauv cov khoom, qauv, thiab cov duab ua tau zoo dua qub, peb dhau los ntawm cov qauv tshiab siv koob ntawm X-ray scintillator khoom, siab clarity thiab siab zog optical ua ke daim iav thiab filling coefficient ntawm 100% CCD nti rhiab heev, duab clarity thiab kev daws teeb meem tau raug txhim kho.
4) Daim ntawv thov kev kho mob ntawm DR muaj kev cia siab dav. Kev siv tshuaj tsawg, hluav taws xob tsawg tsawg rau cov neeg ua haujlwm kho mob thiab kev pabcuam lub neej ntev ntawm cov cuab yeej yog txhua yam zoo ntawm DR Imaging technology. Yog li, DR Imaging muaj qhov zoo hauv lub hauv siab, pob txha thiab lub mis kuaj thiab tau siv dav. Lwm qhov tsis zoo yog tus nqi siab.
3. Kev siv thev naus laus zis ntawm kev kho mob digital imaging - molecular imaging
Molecular imaging yog siv cov kev ntsuas kom nkag siab txog qee cov molecules ntawm cov ntaub so ntswg, cellular thiab subcellular theem, uas tuaj yeem pom kev hloov pauv ntawm qib molecular hauv lub xeev nyob. Nyob rau tib lub sijhawm, peb tseem tuaj yeem siv cov thev naus laus zis no los tshawb txog cov ntaub ntawv ntawm lub neej hauv tib neeg lub cev uas tsis yooj yim pom, thiab tau txais kev kuaj mob thiab lwm yam kev kho mob thaum ntxov ntawm tus kab mob.
4. Txoj kev loj hlob ntawm kev kho mob digital imaging technology
Molecular imaging yog qhov kev tshawb fawb tseem ceeb ntawm kev kho mob digital imaging thev naus laus zis, uas muaj peev xwm los ua qhov kev txhim kho ntawm kev kho mob imaging technology. Nyob rau tib lub sij hawm, classical imaging raws li lub mainstream technology, tseem muaj zoo peev xwm.
