Ko te tomography coherence tomography (OCT) he hangarau whakaahua matatau kua huri i ngā momo mara, ā, he mea nui te mārama ki te putanga OCT hei whakamahi i ōna āheinga. Ko te putanga OCT e pā ana ki ngā raraunga me ngā whakaaturanga tirohanga i hangaia e tētahi pūnaha OCT, e whakamahia ana hei whakarato i ngā whakaahua taipitopito, whakawhiti-wāhanga o ngā kiko koiora, ngā wāhanga whatu, me ētahi atu rauemi.
I tōna pūtake, ka mahi te OCT i runga i te mātāpono o te ine ine taurite-iti. Ka tukuna e te pūnaha OCT te mārama tata-whero ki te tauira e tirohia ana. Ina tūtaki tēnei mārama ki ngā hanganga rerekē i roto i te tauira, ka whakaatahia tetahi wāhanga o taua mārama. Kātahi ka ine te pūnaha OCT i te whakaroa wā me te kaha o ngā ngaru mārama whakaata. Mā te whakataurite i te mārama tohutoro me te mārama whakaata-tauira, ka hangaia he ahua 2D, 3D rānei o te hanganga o roto o te tauira.
Ko te momo putanga OCT tino kitea ko te whakaahua whakawhiti-wāhanga, e rite ana ki te tirohanga moroiti o ngā paparanga o roto o te tauira. E whakaatu ana ēnei whakaahua i ngā kiko rerekē, i ngā rauemi rānei me ngā taumata rerekē o te rerekētanga, e āhei ai te wehewehe mārama i waenga i ngā hanganga. Hei tauira, i roto i ngā tono hauora, ka taea e te whakaahua putanga OCT o te retina te whakaatu mārama i ngā paparanga rerekē o tēnei kiko ngawari, e āhei ai ngā tākuta ki te tātaritanga i ngā mate pēnei i te mate kanohi e pā ana ki te koroheketanga, te mate huka retinopathy, me te glaucoma. Ko te āhua whakataunga teitei o te putanga OCT, me ngā whakataunga axial mai i te 1 ki te 15 micrometers, e whakarato ana i ngā mōhiohio taipitopito he mea tino nui mō te tātaritanga tika.
Haunga ngā whakaahua whakawhiti-wāhanga 2D, ka taea hoki e ngā pūnaha OCT hou te whakaputa i ngā huinga raraunga rōrahi 3D hei putanga. Mā ēnei putanga 3D ka kitea he tirohanga whānui ake o te tauira, ka taea ai te tātari hohonu mai i ngā koki maha. Ka taea e ngā kairangahau te whakamahi i te putanga OCT 3D hei ako i te hoahoa o ngā kiko koiora matatini, pērā i te roro, i ngā oko toto rānei, me te tirotiro me pēhea te huri i roto i te wā. I roto i te mara o te pūtaiao rauemi, ka taea te whakamahi i te putanga OCT 3D hei tātari i te hanganga o roto o ngā rauemi hiato, te kimi hapa, me te aromatawai i te kounga o ngā tukanga hanga.
Ka taea hoki e te putanga OCT te whakauru i ngā raraunga tau e pā ana ki ngā āhuatanga whatu i inehia o te tauira. Tērā pea kei roto i ēnei raraunga ngā mōhiohio e pā ana ki te taupū whakaata, te tauwehenga marara, me te tauwehenga mimiti o ngā rohe rerekē i roto i te tauira. He mea nui ēnei raraunga tau mō te tātari tauanga, e āhei ai ngā kaipūtaiao me ngā tākuta ki te mahi i ngā inenga me ngā whakatairite tika i waenga i ngā tauira rerekē, i ngā wā rerekē rānei.
Ko tētahi atu āhuatanga nui o te putanga OCT ko tōna kaha ki te whakauru atu ki ētahi atu momo whakaahua, ki ngā taputapu tātari raraunga rānei. Hei tauira, ka taea te whakakotahi i te putanga OCT me te whakaahua fluorescence hei whakarato i ngā mōhiohio hanganga me ngā mōhiohio mahi mō te tauira. Hei tāpiri, ka taea te whakamahi i ngā pūmanawa matatau hei tukatuka me te tātari i ngā raraunga putanga OCT, te tango i ngā āhuatanga whai tikanga, me te whakaputa pūrongo mō ngā kaupapa haumanu, rangahau rānei.
Hei whakarāpopototanga, he puna mōhiohio nui te putanga OCT e kapi ana i ngā whakaahua taipitopito, ngā raraunga tau, me te kaha ki te whakauru atu ki ētahi atu hangarau. Ka horapa ōna tono puta noa i te rongoā, te koiora, te pūtaiao rauemi, me te maha atu o ngā mara, e akiaki ana i ngā whanaketanga i roto i te tātaritanga, te rangahau, me te whakahaere kounga. I te whanaketanga tonu o te hangarau OCT, e tumanakohia ana ka pai ake te kounga me te whānui o te putanga OCT, ka whakatuwhera i ngā huarahi hou mō te kimi pūtaiao me te maimoatanga hauora.
