He aha te mea whatu kanohi arotau tomography?

tomography arotau Optical - he kore-urutomo (whakapā-kore) tikanga mō te ako i te hanganga o te kiko kanohi. āhei te reira ki a koutou te tango pikitia o taumira teitei rite whakaritea ki nga hua o ngā tukanga ultrasound. I roto i te meka, te tomography arotau whatu o te kanohi, ko te ahua o te unuhanga, anake hoki te tuatahi, kahore he hiahia mo te taiepa o te tauira kiko.

He hītori poto

Ko te ariā i runga i i whakamana hou tomography arotau whatu, whakawhanakehia e te kairangahau i te Institute o Technology Massachusetts i tawhiti i te 1980. I roto i te tahuri, whakaarohia te whakaaro o te whakauru i te parau tumu hou i roto i te Ophthalmology i roto i 1995 e te pūtaiao American Carmen Puliafito. He tau torutoru i muri, kua whakawhanakehia te kamupene Carl Zeiss Meditec te mea e tika ana, ka karanga te mainuku OCT.

I tēnei wā, me te tauira hou e kore e taea e ako anake te kiko tuaroa, engari ano hoki tomography arotau whatu o te iatuku pūngākau, te faatae te i te taumata mōkitokito.

te mau parau tumu rangahau

tomography arotau Optical ko ki te hanga i ngā whakaahua whakairoiro i runga i te pūtake o te wā inenga roa i roto i te kurupae whakaata marama i te kopa ako. Ko te huānga taketake o tenei kāwai o ngā pūrere mahi superluminescent ngōhiko, te whakamahi o nei hanga reira taea ki te hanga i te kurupae arotau marama iti. I roto i te mau parau te tahi atu, ka whakahohe te kurupae taputapu irahiko i ako te wehea ki te maha nga wahi. whakahaua Kotahi awa te ki te hanganga kiko ako, te tahi atu - ki te whakaata motuhake.

kupu ako, hihi kitea i te ahanoa. I muri, tuhia te raraunga kei te photodetector motuhake. I hanga i runga i te mōhiohio hōtaka taea te diagnostician ki whakatau e pā ana ki te reflectivity i ngā motuhake o te ahanoa uiui. A, no te te oho te wahi i muri o aromatawai tautoko kikokiko ki tetahi atu tūranga.

Optical tomography arotau o te etine hanga reira taea ki te whakaputa whakairoiro i runga i te mata rorohiko, i roto i te mau rave'a e rave rahi e rite ki te hua o te whakamātautau ultrasound.

Tuhinga mo te tukanga

e tūtohu teie mahana, ki te hanga tomography arotau whatu mo te tātaritanga o pathologies pērā i:

• Papahewa.
• ruptures kiko Macular.
• Thrombosis ara toto tuaroa.
• retinopathy mate huka.
• tukanga degenerative i roto i te hanganga kiko kanohi.
• edema Cystoid.
• Kōhikohiko i roto i te mahi o te karere whatu.

I tua atu, ko te tomography arotau whatu o te karere whatu faataahia te ki te aromatawai i te miramira o maimoatanga haumanu whakamahia. I roto i ngā, i te tikanga o te rangahau tavini mahuinga i roto i te whakatau i te kounga o te tāutanga o te pūrere waikeri, ngātahi nei i roto i te kiko kanohi i roto i te papahewa.

Āhuatanga o te tātaritanga

Optical tomography arotau o te tumu parau kau arotahi i runga i tohu motuhake. Ko te kupu i hanga te operator o te pūrere e he maha o te kopa scans ngā.

Nui koretake i rangahau, me te taea tātaritanga arai atu ngā tukanga pathological whai hua pērā i ngawhatanga o te taupoki io, toto auau, rerekē opacities.

E hanga e Hua arotau tomography i te puka o te kawa e whakamōhio ana ngā kairangahau e pā ana ki te mana o etahi wahi o te kikokiko i roto i te ataata me te ngā ine. Mai kei te tuhituhi te raraunga i roto i te mahara, muri kia kia whakamahia ratou ki whakarite te āhua o te kikokiko i mua i te maimoatanga, me te i muri i whakaora maimoatanga.

mātakitaki-ahu toru

hanga Modern tomography arotau whatu reira taea ki te whiwhi kore noa te whakairoiro e rua-ahu, engari ano hoki ki te whakaputa i te mātakitaki e toru-ahu o te taonga. Karapa wāhanga kikokiko i te tere tiketike taea hoki ki te torutoru hēkona hanga i te 50,000 whakapakoko rauemi pāngia. I runga i te pūtake o te ngā mōhiohio riro whakamahi pūmanawa motuhake te aroturuki hanganga toru-ahu o te ahanoa.

Ko te hanga 3D-image ko te pūtake mo te ako o te mahere whenua o nga kopa roto kanohi. Ko te kupu, riro te reira taea ki te tautuhi mārama rohe o pāpaka pathological, me te whakatika o nga akiakinga o ratou huringa i roto i te wa.

Painga arotau tomography

Ko te taputapu whai hua tino hoki e mau ana i roto i tomography pipiri whakaatu te tātaritanga o te papahewa. I roto i te take o waka o tenei kāwai e taea ki te tika te whakatau i ngā āhuatanga māuiuitanga i te tīmatanga o nga wāhanga, ki te tautuhi i te whānuitanga o te ahunga whakamua o te mate mātanga.

Ko mahuinga ia mo te tātaritanga o te taua mate whānui, pērā i e hōloa macular o kikokiko, i roto i nei rite ki te hua o te āhuatanga tau o te tinana o te manawanui tīmata ki te kite i te wahi pango i roto i te pokapū o te kanohi te tikanga o te rangahau.

Tomography pipiri whai hua i roto i te taha ki te tahi atu ngā tukanga tātaritanga, pērā i angiography, te tikanga fluorescence tuaroa. Mā te whakakotahi i ngā tukanga kairangahau whiwhi raraunga tino nui e whai wāhi ki te tātaritanga tika, te whakamāramatanga o te whīwhiwhi o te mate, me te kōwhiringa o te maimoatanga whai hua.

Hea e taea te mahi i tomography arotau whatu?

A amo i te tukanga he taea anake ki te reira ko te kōwae motuhake OCT. Hoki te tātaritanga o te mahere taua, ka taea e koe huihui ki pokapū rangahau hou. Nuinga o ngā wā, kua he tari ako kite, whare hauora ophthalmologic tūmataiti tenei momo o te taputapu.

utu take

E mau ana te arotau tomography titau te aronga o te rata haere, engari ka tonu noa, ki te tetahi tātaritanga te utua. Ko te utu o te ako whakatau te āhua o te māuiuitanga ki te tautuhi i rapu tātaritanga. Hei tauira, te whakamāramatanga o wehenga kiko macular tata i 600-700 moni. I pupuri i te wahi he mārōrō, o te atahanga kiko kanohi e taea te utu i te pokapū tātaritanga manawanui i 800 moni me te ake.

Ko te rangahau integrated e hāngai ana aromatawai i te mahi o te faatae te, weu tūnga tuaroa hanga he tauira e toru-ahu o te okana ataata, te utu mo te taua ratonga tenei ra tīmata i 1800 moni.
