Yuav ua li cas yog kho qhov muag coherence tomography ob lub qhov muag?

Kho qhov muag coherence tomography - ib tug uas tsis yog-tus (uas tsis yog-hu rau) txoj kev rau kev kawm cov qauv ntawm lub qhov muag nqaij. Nws tso cai rau koj coj cov duab ntawm ntau dua kev daws teeb meem raws li muab piv nrog rau cov kev tshwm sim ntawm ultrasound cov txheej txheem. Nyob rau hauv qhov tseeb, tus kho qhov muag coherence tomography ntawm lub qhov muag yog ib yam ntawm cov kev kuaj, tsuas yog rau cov thawj tsis muaj yuav tsum tau rau ib tug laj kab ntawm ib tug cov ntaub so ntswg coj mus kuaj.

Ib tug nyuag cov keeb kwm

Lub tswvyim uas ua niaj hnub kho qhov muag coherence tomography, tsim los ntawm kev soj ntsuam ntawm lub Massachusetts koom haum ntawm Technology nyob rau hauv lub deb 1980s. Nyob rau hauv lem, lub tswv yim ntawm plaug ib tug tshiab hauv paus ntsiab lus nyob rau hauv Ophthalmology twb npaj siab nyob rau hauv 1995 los ntawm cov American paub txog Carmen Puliafito. Ib tug ob peb xyoos tom qab ntawd, lub tuam txhab Carl Zeiss Meditec tau tsim ib qho uas tsim nyog ntsuas, hu ua lub Stratus Oct.

Tam sim no, nrog rau qhov tseeb qauv yuav tsis tau tsuas yog kawm retinal ntaub so ntswg, tab sis kuj kho qhov muag coherence tomography ntawm lub coronary hlab ntsha, cov optic paj nyob rau me me theem.

kev tshawb fawb hauv paus ntsiab lus

Kho qhov muag coherence tomography yog tsim graphic cov dluab ntawm lub hauv paus ntawm kev ntsuas ncua lub sij hawm nyob rau hauv lub thiaj teeb beam ntawm lub kawm ntaub so ntswg. Cov yooj yim caij ntawm pawg no ntawm pab kiag li lawm ua superluminescent diode, kev siv ntawm cov uas yuav ua rau nws tau tsim ib tug tsis tshua muaj coherence teeb kab teeb. Nyob rau hauv lwm yam lus, thaum yuav tus them electron nqaj apparatus yog muab faib ua ob peb qhov chaw. Ib tug kwj yog raws kev coj kom lub tshawb nrhiav cov ntaub so ntswg qauv, lub lwm - rau qhov tshwj xeeb daim iav.

Rays reflected ntawm tus kwv yog summed. Tom qab, cov ntaub ntawv yog kaw tshwj xeeb photodetector. Tsim nyob rau hauv lub sij hawm cov lus qhia pub rau cov diagnostician mus rau kos xaus hais txog tus reflectivity ntawm kev cov ntsiab lus ntawm cov kev soj ntsuam no kwv. Thaum lub tom ntej no feem ntawm kev ntsuag cov ntaub so ntswg pab tsiv mus rau lwm txoj hauj lwm.

Kho qhov muag coherence tomography ntawm lub retina ua rau nws ua tau rau kom muaj graphics rau lub computer screen, uas nyob rau hauv ntau txoj kev uas yog zoo ib yam li cov ntsiab ntawm cov ultrasound xeem.

Indications rau cov txheej txheem

Niaj hnub no, yuav ua rau kho qhov muag coherence tomography yog pom zoo rau cov mob ntawm pathologies xws li:

• GLAUCOMA.
• Macular cov ntaub so ntswg ruptures.
• Thrombosis retinal ntshav paths.
• Ntshav qab zib retinopathy.
• Sib dab nyob rau hauv lub qhov muag cov ntaub so ntswg qauv.
• Cystoid edema.
• Anomalies nyob rau hauv hauj lwm ntawm lub optic paj.

Tsis tas li ntawd, tus kho qhov muag coherence tomography ntawm lub optic paj yog muab mus ntsuam xyuas cov miv nyuas siv zug ntawm kho kev kho mob siv. Nyob rau hauv kev, cov qauv ntawm cov kev tshawb fawb ua hauj lwm pab indispensable nyob rau hauv kev txiav txim zoo ntawm cov installation ntawm lub kua ntaus ntawv, uas yog kev nyob rau hauv lub qhov muag cov ntaub so ntswg nyob rau hauv glaucoma.

Nta ntawm diagnostics

Kho qhov muag coherence tomography ntawm cov kev kawm yuav tsom rau tshwj xeeb tias. Yog li cov neeg teb xov tooj ntawm tus dais no yog ua ib tug xov tooj ntawm successive soj ntaub so ntswg.

Tshuam hamper kev tshawb fawb thiab diagnostics yuav es zoo pathological dab xws li o ntawm lub cornea, profuse hemorrhage, txawv opacities.

Tau coherence tomography yog tsim nyob rau hauv daim ntawv ntawm cov kev cai uas qhia soj ntsuam txog cov xwm txheej ntawm tej qhov chaw ntawm cov ntaub so ntswg nyob rau hauv lub nrig txog kev pom zoo li ua ntau yam lus. Txij li thaum cov ntaub ntawv yog kaw nyob rau hauv lub cim xeeb, tom qab uas lawv yuav tau siv los sib piv rau lub xeev cov ntaub so ntswg ua ntej kev kho mob thiab tom qab kev kho mob kev kho mob.

Peb-dimensional visualization

Niaj hnub nimno kho qhov muag coherence tomography ua rau nws tau mus nrhiav tau tsis tsuas ib tug ob-dimensional graphics, tab sis kuj yuav ua ib tug peb-dimensional visualization ntawm cov khoom. PP cov ntaub so ntswg seem ntawm ib tug kub ceev tso cai rau ib tug ob peb lub vib nas this mus ua ib lub 50,000 dluab thiaj paub hais tias cov ntaub ntawv uas. Nyob rau lub hauv paus ntawm cov ntaub ntawv tau txais tshwj xeeb software reproduces tus saib peb-dimensional qauv ntawm cov kwv.

Lub generated 3D-daim duab yog lub hauv paus rau txoj kev tshawb no ntawm lub topography ntawm lub puab qhov muag ntaub so ntswg. Yog li, nws yuav tau los txhais tau meej thaj tsam ntawm pathological txhab, raws li zoo raws li kho ntawm lub zog ntawm lawv cov kev hloov nyob rau hauv lub sij hawm.

Zoo coherence tomography

Qhov zoo tshaj apparatus rau nqa tawm coherent tomography qhia qhov mob ntawm glaucoma. Nyob rau hauv cov ntaub ntawv ntawm cov tsheb ntawm pawg no tshwj xeeb yog tau los yog txiav txim yam pathology nyob rau hauv thaum ntxov ua sawv, los qhia tias cov twg muaj mob ntawm tus kab mob no.

Cov kev tshawb fawb yog indispensable rau qhov mob ntawm xws li ib tug ntau yam kab mob, xws li macular degeneration ntawm cov ntaub so ntswg, nyob rau hauv uas raws li ib tug tshwm sim ntawm lub hnub nyoog cov yam ntxwv ntawm tus neeg mob lub cev pib mus pom ib tug dub nqaij ntawd nyob rau hauv qhov chaw ntawm lub qhov muag.

Coherent Tomography zoo nyob rau hauv nrog lwm yam diagnostic cov txheej txheem, xws li angiography, lub retinal fluorescence txoj kev. Los ntawm combining cov txheej txheem soj ntsuam tau txais tshwj xeeb nqi ntaub ntawv uas pab txhawb rau lub tseeb mob, lub ntsiab txhais ntawm lub complexity ntawm tus kab mob thiab cov kev xaiv ntawm ib tug zoo kev kho mob.

Qhov twg yuav ua tau kho qhov muag coherence tomography?

Nqa tawm ntawm txoj kev no tsuas yog tau yog hais tias muaj yog ib tug tshwj xeeb chav tsev Oct. Rau cov mob ntawm xws li ib tug lub tswv yim, koj muaj peev xwm chaw uasi mus rau niaj hnub tshawb fawb chaw. Feem ntau cov feem ntau, qhov no hom ntawm cov khoom muaj ib lub zeem muag kho chaw ua hauj lwm, lwm ophthalmologic lub tsev kho mob.

qhov teeb meem nqi

Nqa coherence tomography yuav tsum tau cov kev taw qhia ntawm cov kws kho mob, tiam sis txawm yog hais tias muaj mob yuav tsum them. Tus nqi ntawm txoj kev tshawb txiav txim rau qhov xwm ntawm cov pathology kom paub tias uas nrhiav diagnostics. Piv txwv li, lub ntsiab txhais ntawm macular cov ntaub so ntswg so kwv yees li ntawm 600-700 rubles. Thaum tuav lub anterior ib feem ntawm lub qhov muag cov ntaub so ntswg imaging yuav raug nqi ib tug neeg mob diagnostic chaw nyob 800 rubles thiab tshaj.

Raws li rau integrated tshawb fawb aimed ntawm kev ntsuag hauj lwm ntawm lub optic paj, retinal raws li txoj cai fibers txoj kev ib tug peb-dimensional qauv ntawm lub nrig txog kev pom hloov khoom nruab nrog, tus nqi rau cov kev pab hnub no yog pib los ntawm 1800 rubles.
