Ke Optical momahana tomography mahlo ke efe?

Optical momahana tomography - bao e seng itaolang, (bao e seng ho ikopanya) mokhoa bakeng sa ho ithuta sebōpeho sa leihlo dinama tse nyenyane tse. E lumella hore o nka litšoantšo tsa qeto e phahameng ha li bapisoa le liphello tsa mekgwa ya tshebetso tsa ultrasound. Ha e le hantle, ho Optical momahana tomography leihlo la ke mofuta oa biopsy, feela bakeng sa ea pele ha ho hlokahale bakeng sa terata ya sampole dinama tse nyenyane tse.

A histori e khutšoanyane

ya kgopolo ya ho tseo a ileng ae etsa ea kajeno Optical momahana tomography, ntshetswa pele ke bafuputsi ba ka Institute ea Technology Massachusetts ka hōle bo 1980. Ka lehlakoreng le leng, khopolo ea ho kenyelletsa le molao-motheo o mocha oa ophthalmology ile sisintsweng ka 1995 ke le rasaense ea American Carmen Puliafito. A lilemo tse seng kae hamorao, khampani Carl Zeiss Meditec e ntshetswa pele seletsa loketseng, e bitsoang Stratus Oct.

Hona joale, le ea mohlala morao-rao ke ke feela ithuta dinama tse nyenyane tse retina, empa hape Optical momahana tomography tsa methapo gogoga, le methapo ea kutlo optic ka phahameng ka ho nyenyane haholo.

melao-motheo ea ho etsa lipatlisiso

Optical momahana tomography ke ho theha litšoantšo hlakileng ka lebaka la nako ea ho lekanya tieho toloki bonahatsa leseli le tsoang ho ka lisele ithutileng tsona. Karolo ea motheo ea sehlopha sena a maqheka sebetsang sebakeng sa hae superluminescent diode, tšebeliso ea e etsang hore ho be bonolo ho theha e tlaase momahana khanya libalaka.

Ha karolo e latelang ea lekola dinama tse nyenyane tse tšehetso e ba ile ba fallela sebakeng se seng.

Optical momahana tomography tsa retina e etsa ho ka khoneha ho hlahisa Grafiken ka k'homphieutheng, eo ka litsela tse ngata tse tšoanang le sephetho sa ultrasound maemong hlahloba.

Ho bonahala ho buuoa

Kajeno, ho etsa Optical momahana tomography buelloa bakeng sa fumanoe tsa pathologies tse kang:

• Glaucoma.
• Macular dinama tse nyenyane tse ruptures.
• Thrombosis litsela tsa mali retina.
• Lefu la tsoekere foufatsang.
