Negatoscopes yog ib qho ntawm cov cuab yeej siv kho mob tseem ceeb uas tuaj yeem pom hauv kev ua yeeb yaj kiab, chav kho mob xwm txheej ceev lossis chaw kho mob. Kev nyeem cov duab xoo hluav taws xob los ntawm cov kws kho hluav taws xob, kws tshaj lij lossis kws tshaj lij yog cov kauj ruam tseem ceeb hauv kev teeb tsa kev kuaj mob thiab ua tus saib xyuas cov kab mob tseem ceeb.

Cov negatoscopes yog cov teeb pom kev zoo rov qab uas ua rau nws muaj peev xwm nyeem X-duab los ntawm kev ua kom pom tseeb. Diffused teeb pom kev zoo ib yam li lub teeb pom kev zoo. Kev nyeem qhov tseeb ntawm X-duab duab thiab qhov tseeb ntawm kev kuaj mob tshwm sim ncaj qha rau qhov zoo ntawm qhov teeb pom kev zoo no.

Muaj pes tsawg leeg

Kev tsis pom zoo ib txwm yog cov thawv, ib qho ntawm ob sab ntev uas yog lub iav ci ci rov qab. Lub pane no tso cai rau lub teeb kom sib npaug thoob plaws nws qhov chaw.

Cov negatoscopes muaj nyob hauv ntau qhov sib txawv nrog rau 1 txog 4 qib kev nyeem ntawv, uas tuaj yeem hloov pauv ua ke lossis cais. Lawv qhov loj me haum rau feem ntau xoo hluav taws xob ntawm cov neeg laus lossis menyuam yaus. Lub zog tau muab los ntawm lub hauv paus los ntawm lub pob nyem rau / tawm. Ntawm qee tus qauv, lub teeb pom kev tuaj yeem hloov kho los ntawm lub teeb pom kev zoo tso cai rau hloov kho lub teeb pom kev zoo. Cov xim kub ntawm cov raj roj fluorescent yog nruab nrab ntawm 6100 thiab 7220 Kelvins. Cov negatoscopes muaj nyob hauv cov qauv ntsug kom dai ntawm phab ntsa lossis hauv tus qauv kab rov tav los tso rau ntawm lub rooj sawv ntsug.

Kev xoo hluav taws xob yog ib qib uas nquag siv los tsim lossis lees paub qhov kev kuaj mob. Nov yog cov ntawv xeem nrawm thiab yooj yim los ua. Tus neeg mob tau raug nqaj ntawm X-ray. Cov hluav taws xob, uas dhau los ntawm lub cev, ntau dua lossis tsawg dua raws li qhov ntom ntom ntawm cov ntaub so ntswg lossis lub cev hla.

Nyeem xoo hluav taws xob

• Cov ntaub so ntswg tuab heev, xws li cov pob txha, ua rau cov kab xoo hluav taws xob hla dhau mus: lawv pom cov xim dawb hauv daim duab;
• Cov ntaub so ntswg nruab nrab, xws li cov leeg, ua kom qis qis X-rays: lawv pom greyish ntawm X-ray;
• Cov ntaub so ntswg qis, xws li dej lossis huab cua, tsis yooj yim ua rau xoo hluav taws xob: lawv pom cov xim tsaus rau ntawm daim duab.

Cov duab ntawm cov ntaub so ntswg sab hauv tau sau rau ntawm x-ray zaj duab xis tuaj yeem sib piv lub hlwb mus rau "duab ib txwm". Ib qho txawv txav tam sim no stain yuav muaj feem cuam tshuam nrog pathology.

Kev txhais cov duab hluav taws xob

Hauv kev phais orthopedic, xoo hluav taws xob ua rau nws muaj peev xwm hais txog ntau yam ua rau mob ntawm cov leeg musculoskeletal:

• pob txha puas;
• puas tsuaj rau pob txha mos ntawm cov pob qij txha;
• tawg ntawm cov leeg;
• thiab lwm yam

X-rays kuj tuaj yeem kuaj pom:

• lub plawv dhia;
• mob ntsws;
• qog nqaij hlav;
• pulmonary emphysema;
• txoj hnyuv tu;
• ntau yam mob;
• thiab lwm yam

Cov theem ntawm kev ua haujlwm

Tus kws kho mob tso daim duab X-duab duab uas nws xav nyeem ntawm lub phaj ntawm X-ray saib thiab tig rau ntawm lub phaj uas sib haum. Nyob rau hauv cov ntaub ntawv ntawm ntsug negatoscopes, cov duab "clipped" rau hauv qhov zawj nyob rau saum lub iav. Kev nyeem ntawv tau ua tiav los ntawm kev ua kom pom kev ua tsaug rau teeb pom kev zoo los ntawm cov hlab roj fluorescent uas nthuav tawm lub teeb zoo ib yam li lub teeb pom kev.

Thaum twg siv nws?

Xoo hluav taws xob tau siv los nyeem X-duab duab hauv ntau lub tsev kho mob thiab hauv kws kho mob lub chaw haujlwm.

Kev saib xyuas ntawm tus xoo hluav taws xob saib

Txhawm rau ua kom X-ray saib ua haujlwm tau zoo thiab txhawm rau kom nyeem tau zoo tshaj plaws ntawm X-duab, ntau qhov ntsuas yuav tsum tau tshuaj xyuas tas li:

• qhov huv ntawm iav;
• qhov ci ntsa iab, uas yuav tsum nyob twj ywm sib xws thoob plaws saum npoo ntawm lub lauj kaub;
• qhov kub ntawm cov hlab, uas yuav tsum tau tshuaj xyuas tas li txhawm rau txhawm rau txheeb xyuas cov teeb pom kev tsis sib xws.

Cov qauv sib txawv ntawm negatoscope

• X-ray xoo hluav taws xob zoo ib yam: qhov no yog tus qauv pom nyob hauv tsev kho mob lossis kws kho mob lub chaw haujlwm. Nws tau qhib ua haujlwm ntawm tus kheej los ntawm ib lossis ntau qhov hloov pauv uas pab kom nyeem tau ntau yam kom raug qhib. Cov kab no tuaj yeem teeb cais lossis ib txhij. Qee cov qauv tau nruab nrog lub dimmer;
• Tus qauv-tiaj ntxiv muaj hom teeb pom kev zoo sib xws uas tsis muaj qhov cuam tshuam stroboscopic (ua kom pom kev ntawm lub teeb). Nws muaj 1 txog 4 qib thiab muaj qhov dimmer;
• Lub tshuab xoo hluav taws xob tsis siv neeg: qhov hloov pauv tau ua tiav thaum muab daim duab tso rau. Lub teeb tuaj ntawm ib tus zuj zus;
• Tus kws kho hniav xoo hluav taws xob tso cai rau cov kws kho hniav thiab kws kho hniav nyeem tau zoo heev ntawm xoo hluav taws xob: panoramic x-rays, retro-alveolar x-rays, ntsuas ntev-lub khob hliav qab;
• Cov "neeg tiam tshiab" kev kho mob X-ray saib tau lees tias muaj zog thiab zoo ib yam nkaus xwb. Nws cov ntaub ntawv muaj zog heev thiab nws txoj kev ua neej nyob ntev yuav luag tsis kawg. Nws cov khoom siv hluav taws xob ua tau raws cov qauv nruj heev. Tag nrho cov no ua rau nws lub thawv teeb ruaj khov heev. Ntawm qee tus qauv, lub teeb pom kev tuaj yeem hloov kho los ntawm lub dimmer. Cov qauv nrog cov duab sib xyaw ua ke muaj lub thawv ergonomic thiab tsim nyog. Kev teeb tsa tuaj yeem yog kab rov tav, ntsug, thiab ntawm cov hlau sawv ntsug.

Cov txheej txheem rau xaiv tus saib raug

• Tus naj npawb ntawm txoj kab: los ntawm 1 txog 4 txoj kab feem ntau, tab sis muaj cov qauv mus txog 12 txoj kab thiab ntau dua;
• qhov zoo ntawm lub teeb;
• pib hais kom ua;
• ua raws li cov qauv kev nyab xeeb;
• CE npav.

Lwm yam kev siv X-ray saib

Peb siv negatoscopes hauv lwm qhov tsis yog kev kho mob:

• hauv kev yees duab los nyeem qhov tsis zoo lossis swb;
• nyob rau hauv luam ntawv rau mounting offset films los yog nyob rau hauv screen luam ntawv;
• hauv cov duab kos kom taug qab cov duab lossis ua montages.
