Chii Manyiminya coherence tomography maziso?

Optical coherence tomography - asiri invasive (non-kuonana) nzira yokudzidza sechivako ziso tishu. Kunoitawo kuti kutora mifananidzo dzakakwirira chisarudzo sezvo kuenzaniswa nemigumisiro Ultrasound maitirwe ezvinhu. Kutaura zvazviri, Manyiminya coherence tomography ziso rudzi biopsy, chete wokutanga pasina kudikanwa fence imwe tishu waungapa.

Nhoroondo Pfupi

Pfungwa iri iyo akaita ano Manyiminya coherence tomography, yakataurwa vatsvakurudzi panguva iri Massachusetts Institute of Technology ari kure 1980s. Zvadaro, pfungwa Pakusuma musimboti itsva ophthalmology akanga aronga muna 1995 neAmerican musayendisiti Carmen Puliafito. Makore mashomanana gare gare, kambani Carl Zeiss Meditec kwakasimbiswa rakakodzera mudziyo, yainzi Stratus Oct.

Pari pamwe azvino womuenzaniso havagoni chete kudzidza retinal rinenge asiwo Manyiminya coherence tomography pamusoro coronary arteries, ari optic etsinga panguva nemaziso chechetere.

tsvakurudzo misimboti

Optical coherence tomography kuti aumbe zvakajeka mifananidzo pahwaro yakayerwa kunonoka nguva kuratidzwa chiedza danda kubva aidzidza munyama. The chinokosha muchikwata ichi mano anoita superluminescent diode, kushandiswa izvo zvinoita kuti tikwanise kuumba pasi coherence chiedza matanda. Nemamwe mashoko, kana simba iri mhosva Erekitironi danda midziyo rakakamurwa akawanda nhengo. Mumwe Rwizi inoendeswa kudzidzwa zvinyama mamiriro, mumwe - chaihwo girazi.

Mwaranzi zvinooneka kubva chinhu zviri muchidimbu. Zvadaro, humboo yakanyorwa chinokosha photodetector. Akaumba pamusoro purogiramu mashoko anobvumira diagnostician kuti vafunga pamusoro reflectivity panguva chaiyo pfungwa yacho kuongororwa chinhu. iri kana rinotevera chikamu dzinoongorora zvinyama rutsigiro vakatamira kune imwe nzvimbo.

Optical coherence tomography of the retina runoita kuti vaunze Graphics pamusoro pakombiyuta, izvo munzira dzakawanda dzakafanana migumisiro Ultrasound bvunzo.

Zvairatidza kuti nzira

Nhasi, kuti Manyiminya coherence tomography pachii nechirwere kuti pathologies akadai:

• Yemaziso.
• Macular tishu ruptures.
• Thrombosis retinal nzira ropa.
• Shuga retinopathy.
• Chinopedza pezvakaitwa muziso tishu mamiriro.
• Cystoid edema.
• Anomalies vari kushanda optic etsinga.

Uyezve, Manyiminya coherence tomography pamusoro optic etsinga iri basa rokuongorora efficacy pakati kuchirapa nokurapwa kushandiswa. Kunyanya, nzira kutsvakurudza kushumira hunokosha kuona kunaka kugadzwa abudise mudziyo, riri revatema muziso rinenge riri yemaziso.

Zvinoumba Diagnostics

Optical coherence tomography pamusoro penyaya kunosanganisira kutaura dzinokosha mavanga. Saka opareta ari mudziyo anoitwa inoverengeka anotevedzana Scans munyama.

Substantially kungatadzisa tsvakurudza uye Diagnostics ringamisa zvinobudirira pathological pezvakaitwa akadai mumatenhere ari cornea, kunonyengedza ropa, zvakasiyana opacities.

Results coherence tomography vari akaumba muchimiro protocols kuti vaudze vatsvakurudzi pamusoro mamiriro zvimwe zvikamu zvinyama iri kutarisana uyewo quantitative mazwi. Sezvo mashoko akanyorwa ndangariro, vakabva aitwe kuenzanisa mamiriro zvinyama vasati kurapwa uye pashure kurapwa kurapa.

Three-dimensional Visualization

Modern Manyiminya coherence tomography runoita kuti vawane kwete chete mbiri-dimensional Graphics, asiwo kuti pave-dimensional matatu Visualization of zvinhu. Kushanda pakuvheneka zvinyama zvikamu kumhanya chaizvo kunoita kuti masekondi mashoma kuti vaumbe 50,000 mifananidzo chirwere zvinhu. Pahwaro mashoko akapiwa Software rinokosha reproduces ari tarisisa-dimensional matatu nemamiriro chinhu.

The vanowanika 3D-mufananidzo ndiyo hwaro adzidze kwakaita nzvimbo yacho yomukati ziso munyama. Saka, zvinovawo zvinobvira kurondedzera miganhu zvakajeka pathological maronda, uyewo kutara simba rinomutsa kuchinja zvavo nenguva.

Advantages coherence tomography

Inobudirira zvikuru midziyo yokuita coherent tomography inoratidza chirwere kuti yemaziso. Kana motokari ose muchikwata ichi vanachiremba vanogona zvakarurama kuona zvinhu zvokurwara mukuvamba mumatanho, kuziva mwero kunoita chirwere chacho.

Nzira kutsvakurudza hunokosha kuti chirwere zvakadaro kwakapararira zvirwere, zvakadai macular degeneration kuti rinenge iyo nemhaka nemakore zvatariswa muviri murwere anotanga kuona dema gwapa pakati ziso.

Coherent Tomography kunobudirira pachiimbwa dzimwe chirwere dzokuvhiya, akadai angiography, ari retinal fluorescence nzira. Nokuva Matanho mutsvakurudzi anowana mashoko kunyanya zvinokosha kuti pave zvakarurama nechirwere, tsanangudzo kunzwisisa chirwere uye kusarudzwa anobudirira kurapwa.

Ndokupi kuita Manyiminya coherence tomography?

Kuita nzira zvinogoneka chete kana pane unyanzvi chikwata Oct. Nokuti nechirwere hurongwa hwakadaro, unogona kushandisa ano tsvakurudzo nzvimbo. Kakawanda, kwakadai midziyo ine chiratidzo kururamiswa mahofisi, private ophthalmologic kiriniki.

nyaya mutengo

Akatakura coherence tomography zvinoda peDare kupinda chiremba, asi kunyange kana paine chirwere achagara kubhadharwa. Mari pakudzidza kunotema yezvakaita zvokurwara kuziva inotsvaka Diagnostics. Somuenzaniso, tsanangudzo macular zvinyama musisiri vanofungidzirwa 600-700 rubles. Apo akabata Anterior chikamu ziso rinenge kuri hungada murwere chirwere muzinda pa 800 rubles uye zvakawanda.

Kana zvidzidzo Integrated zvainanga dzinoongorora kushanda optic etsinga, retinal mamiriro fibers wezvamatongerwe-dimensional matatu muenzaniso kuona nhengo, mutengo mabasa akadai nhasi rinotanga kubva 1800 rubles.
