Kev kho mob imaging yog dab tsi?
Nuclear kev kho mob imaging (tseem hu ua radionuclide scanning) yog ib qho kev kuaj mob zoo vim nws qhia tsis tau tsuas yog lub cev nqaij daim tawv (cov qauv) ntawm lub cev lossis lub cev, tab sis kev ua haujlwm ntawm lub cev thiab.Qhov "cov ntaub ntawv ua haujlwm" ntxiv no tso cai rau cov tshuaj nuclear txhawm rau kuaj xyuas qee yam kab mob thiab ntau yam kev kho mob sai dua li lwm yam kev kuaj mob uas muab cov ntaub ntawv tseem ceeb ntawm lub cev (cov qauv) txog lub cev lossis lub cev.Cov tshuaj Nuclear tuaj yeem muaj txiaj ntsig zoo hauv kev kuaj mob thaum ntxov, kev kho mob, thiab kev tiv thaiv ntau yam kev kho mob thiab txuas ntxiv loj hlob raws li cov cuab yeej kho mob muaj zog.
RAU LUB TSEV KAWM NTAWV HEALTHCARE INSTITUTIONS uas muab kev tswj xyuas kev kuaj mob uas yog ib feem ntawm lawv lub neej txhua hnub rau kev siv hluav taws xob dav dav (xws li, CT, MR, X-ray, PET, SPECT, thiab lwm yam).Txawm li cas los xij, cov kws tshaj lij hauv cov tsev kawm ntawv no, los ntawm cov kws kho mob, cov kws tshaj lij, thiab cov thawj coj, mus rau PACS / IT cov neeg ua haujlwm, kuj tau hnov qhov mob ntawm qhov tsis muaj PACS cov kev daws teeb meem rau ntau qhov sib txawv.Cov kev ua haujlwm tsis zoo tshaj plaws los ntawm PACS yog cov qauv kev kuaj pom ntawm lub cev, suav nrog PET-CT, SPECT-CT, nuclear cardiology, thiab cov tshuaj nuclear dav dav.
Txawm hais tias qhov kev ntsuam xyuas ntawm cov khoom siv hluav taws xob yog qhov me me los ntawm cov kev kuaj xyuas ib xyoos twg, nws qhov tseem ceeb tsis yog qhov tseem ceeb, ob qho tib si kho mob thiab nyiaj txiag.PET-CT tau raug pov thawj tias yog qhov kev hloov pauv ntawm qhov tseeb thaum nws los txog rau kev kuaj mob qog noj ntshav.Nuclear cardiology tau yog qhov kev xaiv ntawm kev xaiv rau cov tsis muaj kab mob plawv.General nuclear tshuaj muab ntau daim ntawv thov kev ua haujlwm uas tsis muaj lwm yam kev hloov pauv tau.Nyiaj txiag, PET-CT thiab nuclear cardiology tseem yog cov txheej txheem them rov qab siab tshaj plaws hauv kev kuaj pom.
Dab tsi ua rau nuclear kev kho mob molecular imaging txawv ntawm cov radiology modalities yog cov qub dluab lub zog ntawm lub cev, thaum lub tom kawg dluab lub anatomy ntawm lub cev.Qhov no yog vim li cas nuclear molecular imaging qee zaum kuj hu ua metabolic imaging.Txhawm rau txheeb xyuas cov haujlwm ntawm lub cev los ntawm cov duab tau txais, yuav tsum tau saib tshwj xeeb thiab tshuaj xyuas cov cuab yeej.Cov cuab yeej no yog qhov uas ploj lawm los ntawm feem ntau ntawm PACS niaj hnub no.
Hais txog qhov no, Ntau thiab ntau lub tuam txhab kev kho mob imaging technology xav tsim lub cim tshiab PET, SPECT.
Vim li cas thiaj xaiv Kinheng:
1.Minimal pixel dimension muaj
2.Txo optical crosstalk
3.Zoo uniformity ntawm pixel rau pixel / Array rau array
4.TiO2/BaSO4/ESR/E60 reflectors muaj
5.Pixel Gap: 0.08, 0.1, 0.2, 0.3mm
6.Kev ntsuas kev ua tau zoo muaj

Mechanical tsim rau assembling:
Raws li qhov kawg ntawm kev siv cov array sib dhos, muaj ntau hom kev tsim kho tshuab los ntawm Kinheng kom tau raws li kev kho mob thiab kev soj ntsuam kev lag luam.
1D Liner array yog tsuas yog siv rau kev soj ntsuam kev ruaj ntseg industy, xws li Bagger scanner, Aviation scanner, 3D scanner thiab NDT.Cov ntaub ntawv suav nrog CsI (Tl), GOS: Tb / Pr Zaj Duab Xis, GAGG: Ce, CdWO4 scintillator thiab lwm yam. Lawv feem ntau txuas nrog Silicon Photodiode kab array rau nyeem tawm.
2D array feem ntau yog siv rau kev kos duab, suav nrog Kev Kho Mob (SPECT, PET, PET-CT, ToF-PET), SEM, Gamma lub koob yees duab.Cov 2D array no feem ntau ua ke nrog SIPM array, PMT array nyeem tawm.Kinheng muab 2D array suav nrog LYSO, CsI(Tl), LSO, GAGG, YSO, CsI(Na), BGO scintillator thiab lwm yam.
Hauv qab no yog kinheng feem ntau tsim cov duab kos rau 1D Thiab 2D array rau kev lag luam.
