Optical coherence tomography (OCT) inyanzvi yekuona mifananidzo yepamusoro yakachinja nzvimbo dzakasiyana-siyana, uye kunzwisisa OCT output kwakakosha pakushandisa kugona kwayo. OCT output inoreva data uye mifananidzo inoonekwa inogadzirwa neOCT system, iyo inoshandiswa kupa mifananidzo yakadzama, yakapatsanurwa yematishu ehupenyu, zvikamu zveoptical, nezvimwe zvinhu.
Pakati payo, OCT inoshanda zvichibva papfungwa yekubatana kwakaderera. Sisitimu yeOCT inoburitsa chiedza cheinfrared chiri pedyo nesampuro chiri kuongororwa. Kana chiedza ichi chikasangana nemaumbirwo akasiyana mukati mesampuro, chikamu chacho chinodzoserwa kumashure. Sisitimu yeOCT inobva yayera kunonoka kwenguva uye simba remafungu echiedza adzoserwa. Nekuenzanisa chiedza chereferensi nechiedza chemuenzaniso chadzoserwa, inovaka mufananidzo we2D kana 3D wechimiro chemukati mesampuro.
Chimiro chinowanzoonekwa cheOCT output mufananidzo wechikamu, uyo wakafanana nekuona kwemukati memuenzaniso ne microscope. Mifananidzo iyi inoratidza matishu akasiyana kana zvinhu zvine mwero wakasiyana, zvichibvumira kusiyanisa kwakajeka pakati pezvimiro. Semuenzaniso, mukushandiswa kwekurapa, mufananidzo weOCT output we retina unogona kuratidza zvakajeka matishu akasiyana enyama iyi yakapfava, zvichigonesa vanachiremba kuongorora zvirwere zvakaita sekuora kwemacular zvine chekuita nezera, chirwere cheshuga retinopathy, uye glaucoma. Hunhu hweOCT output hwakanyanya, neaxial resolutions inowanzo bva pa1 kusvika ku15 micrometers, inopa ruzivo rwakadzama runokosha pakuongorora kwakarurama.
Kuwedzera kumifananidzo ye2D cross-sectional, masisitimu emazuva ano eOCT anogonawo kugadzira data re3D volumetric sets se output. Izvi zvinobuda mu3D zvinopa maonero akazara emuenzaniso, zvichibvumira kuongororwa kwakadzama kubva kumakona akasiyana-siyana. Vaongorori vanogona kushandisa 3D OCT output kudzidza magadzirirwo ematishu akaomarara ebhayoloji, akadai seuropi kana mitsipa yeropa, uye kuona kuti anochinja sei nekufamba kwenguva. Mumunda wesainzi yezvinhu, 3D OCT output inogona kushandiswa kuongorora chimiro chemukati chezvinhu zvakasanganiswa, kuona zvikanganiso, uye kuongorora mhando yemaitiro ekugadzira.
OCT output inogonawo kusanganisira data renhamba rine chekuita nemaonero ekuona emuenzaniso. Data iri rinogona kusanganisira ruzivo nezve refractive index, scattering coefficient, uye absorption coefficient yenzvimbo dzakasiyana mukati memuenzaniso. Data renhamba rakadaro rinokosha pakuongorora huwandu, zvichigonesa masayendisiti nevanachiremba kuita zviyero zvakarurama uye kuenzanisa pakati pemasampuli akasiyana kana panguva dzakasiyana.
Chimwe chinhu chakakosha cheOCT output kugona kwayo kubatanidzwa nedzimwe nzira dzekufungidzira kana maturusi ekuongorora data. Semuenzaniso, OCT output inogona kubatanidzwa ne fluorescence imaging kuti ipe ruzivo rwechimiro uye mashandiro emuenzaniso. Pamusoro pezvo, software yakaoma inogona kushandiswa kugadzirisa nekuongorora data reOCT output, kubvisa zvinhu zvine musoro, uye kugadzira mishumo yezvinangwa zvekiriniki kana zvekutsvagisa.
Muchidimbu, OCT output inzvimbo yakapfuma yeruzivo inosanganisira mifananidzo yakadzama, data renhamba, uye mukana wekubatanidzwa nemamwe matekinoroji. Mashandisirwo ayo anosanganisira mushonga, biology, sainzi yezvinhu, nedzimwe nzvimbo dzakawanda, zvichitungamira kufambira mberi mukuongorora, kutsvagisa, uye kudzora mhando. Sezvo tekinoroji yeOCT ichiramba ichichinja, mhando uye kushanduka-shanduka kweOCT output zvinotarisirwa kuwedzera kuvandudzika, zvichivhura mikana mitsva yekuwana sainzi uye kurapwa.
