Yintoni okubonakalayo emehlweni kuhambelana Itomography?

ukubumbana Optical Itomography - a non-invasive test (non-contact) indlela ukufunda isakhiwo ijwabu. It ikuvumela ukuba uthathe imifanekiso isisombululo eliphezulu xa kuthelekiswa neziphumo iinkqubo ultrasound. Enyanisweni, lo namathelwano Itomography woqondo ye iliso luhlobo biopsy, kuphela ngenxa yokuqala akukho mfuneko elucingweni kwaso isampuli kwithishyu.

Imbali emfutshane

Ingcamango kuyo eyenziwa mihla lokunamathelana enombala Itomography, eziphuhliswe abaphandi kwi Massachusetts Institute of Technology in kude 1980. Ngenxa yoko, ingcamango yokuqalisa umgaqo omtsha zamehlo yaphakanyiswa ngo-1995 yi-nzulu American Carmen Puliafito. Kwiminyaka embalwa kamva, inkampani Carl Zeiss Meditec kuphuhliswe isixhobo esifanelekileyo, ebizwa ngokuba Stratus uOCT.

Okwangoku, kunye imodeli entsha ayikwazi kuphela ukufunda izihlunu semehlo, kodwa enombala namathelwano Itomography kwemithambo yenhliziyo, i-luvo optic kwinqanaba ezincane.

izimiso zophando

Optical kunamathelwano Itomography kukuba ukwenza imifanekiso graphic ngokusekelwe kwexesha womlinganiselo ukulibaziseka umqadi yokukhanya okuvela emzimbeni bafunda. Into engundoqo yolu didi kwezixhobo izenzo superluminescent diode, ukusetyenziswa leyo yenza kube lula ukwenza i imiqadi namathelwano ekukhanyeni low. Ngamanye amazwi, xa isebenze ebizwayo electron umqadi izixhobo yahlulwe eziliqela. Okukodwa sibhekiswe isakhiwo inyama behlolisisa, enye - ukuya esipilini ekhethekileyo.

Rays kubonakala ukusuka kwinto nje bubonke. Emva koko, lo Idatha irekhodwa photodetector okhethekileyo. Kwakheka kwi ulwazi kwishedyuli ye kuvumela diagnostician ukuze bafikelele kwizigqibo malunga reflectivity kwiindawo ezithile into uphando. Xa ingxenye elandelayo yokuvavanya inkxaso inyama siyasuswa sibekwe kwenye indawo.

Optical yokuvumelana Itomography le retina yenza kube lula ukwenza imizobo kwi computer, apho ngeendlela ezininzi ezifanayo iziphumo zeemviwo ultrasound.

Izinto ezibonisa ukuba inkqubo

Namhlanje, ukuze ibone Itomography enombala nekucetyiswa ukuba lokufunyaniswa ezimbi ezifana:

• Glaucoma.
• ugqabhuka zeethishu Macular.
• Thrombosis iindlela igazi semehlo.
• retinopathy seswekile.
• iinkqubo sisiba mandundu kubume ijwabu.
• nokudumba Cystoid.
• Mgaqweni ekusebenzeni kwi-luvo optic.

Ngaphezu koko, lo namathelwano Itomography woqondo le-luvo optic lwanziwa ukuvavanya ukusebenza unyango zonyango ezisetyenziswayo. Ngokukodwa, indlela yophando isebenza buyafuneka ekumiseleni umgangatho ukufakelwa isixhobo amanzi, nto leyo ihlanganiswe emehlweni esikule glaucoma.

Iimpawu noxilongo

Optical yokuvumelana Itomography isifundo kuquka ugxininise ngeempawu ezithile. Ngaloo nomsebenzisi ifowuni wenza inani izicwili scan ezilandelelanayo.

Kakhulu ziphazamise uphando yaye uxilongo elingama iinkqubo ezisebenzayo zophendlo lwezifo ezifana ukudumba i inwebu, Ukopha lweenkcukacha, opacities ezahlukeneyo.

Iziphumo kunamathelwano Itomography akhiwa kule fom ye applet ukwazisa abaphandi malunga nemeko iinxalenye ezithile esikule ezibonakalayo kwakunye amagama oluninzi. Ekubeni data zibhalwa kwimemori, kamva ukuze zingasetyenziswa ukuthelekisa imeko yethishyu phambi kokuba unyango kunye nasemva amakhambi unyango.

ngeso-ntathu

Modern ukubumbana optical Itomography yenza kube lula ukufumana indlela yemizobo ezikumila kumacala mabini kuphela, kodwa ukuvelisa nokuthelekelela-ntathu iinjongo. Ukuhlolisisa amacandelo zeethishu ngesantya esiphezulu kuvumela imizuzwana embalwa ukwenza imifanekiso 50,000 impahla isifo. Ngenxa yolwazi efunyenweyo software eyodwa izalana esweni isakhiwo-ntathu le into.

I-3D-umfanekiso eyenziwe sisiseko isifundo isimo se ancedisana iliso embilwini. Ngoko, kuba nokwenzeka ukuchaza imida ecacileyo izilonda lwezidumbu, kwakunye ukulungiswa malunga nemiba zotshintsho zazo kwangethuba.

Izinto eziluncedo kuhambelana Itomography

Izixhobo ngokukuko ekuqhubeni Itomography inonamathelwano ukubonisa lokufunyaniswa glaucoma. Kwimeko iimoto kolu didi iingcali bayakwazi ukukhangela izinto ngezifo ngokuchanekileyo usaqala, ukuchonga kangangoko ukuqhubeka kwesifo.

Indlela yophando buyafuneka ukuze lokufunyaniswa a izifo kangaka, ezifana yamehlo macular kwithishyu, apho ngenxa iimpawu ubudala emzimbeni wakhe eqala ukubona ibala elimnyama embindini iliso.

Itomography inonamathelwano ngempumelelo kunye nezinye iindlela zokuxilonga, ezifana angiography, indlela fluorescence semehlo. Ngokuhlanganisa iinkqubo umphandi ifumana data ngokukodwa ezixabisekileyo enegalelo uxilongo echanekileyo, inkcazelo ukuntsonkotha sifo kunye nokukhethwa wonyango olusebenzayo.

Phi na ukwenza enombala kuhambelana Itomography?

Ukufeza le nkqubo kunokwenzeka kuphela xa kukho iyunithi ezizodwa uOCT. Kuba lokufunyaniswa eso sicwangciso, uyakwazi ukubhenela kwamaziko ophando mihla. Amaninzi, olu hlobo inazo umbono ofisi ukulungiswa, iklinikhi ophthalmologic.

ixabiso udaba

Siphethe yokuvumelana Itomography kufuna ulwalathiso gqirha ukuya, kodwa ukuba Uxilongo iya kusoloko kuhlawulwa. Iindleko phando limisela uhlobo ngezifo ukuchonga efuna uxilongo. Umzekelo, inkcazelo okuphumla zeethishu macular kuqikelelwa kwi 600-700 engange. Ngexesha ubambe i inxalenye Icipande mishini ijwabu zinokubiza iziko nomonde diagnostic kwi engange-800 nangaphezulu.

Ke zona izifundo ezihlangeneyo ojonge ukuvavanya ukusebenza luvo optic, ubume imicu semehlo ngokuvula umfuziselo-ntathu welungu ezibonakalayo, ixabiso iinkonzo ezinjalo namhlanje iqala 1800 engange.
