B - Luam theej duab - hais txog cov duab tsim thaum cov ntaub ntawv sau los ntawm ib qho Kev tshuaj xyuas ultrasonic yog plotted rau ib tug cross-sectional saib ntawm lub Cheebtsam. Cov ntawv thov raug pom muaj nyob hauv ultrasonic Phaj array kev tshuaj xyuas.
Koj ua li cas thiaj kuaj B?
Txoj kev ua tau zoo tshaj plaws los tshuaj xyuas qhov dav ntawm cov retina thaum lub sijhawm B - scan yog siv cov txheej txheem limbus-rau-fornix. Rau ua Cov txheej txheem no, tus kws kho mob ultrasound yuav tsum maj mam glide qhov kev sojntsuam los ntawm lub limbus ntawm lub qhov muag mus rau fornix nyob rau hauv ib qho kev cheb cheb kom ntau npaum li cas ntawm retina pom thaum lub sij hawm lub sij hawm. scan.
