Umuntu uthanda ukwazi, ngisho nakwabesifazane abakhulelwe. Ngaphandle kokungabaza, wonke umama wesikhathi esizayo ubuzwa nsuku zonke ngemibuzo mayelana nokuthi ingane yakhe izwa kanjani emathunjini, ukuthi kubonakala kanjani, ukuthi yenzani ngesikhathi esithile, njll. Ngenhlanhla, isayensi nobuchwepheshe abukami, futhi, ukuze kulondolozwe ukuthula kwengqondo, izimpendulo kuzo zonke imibuzo ezithandekayo kwabesifazane abakhulelwe futhi hhayi nje kuphela ezakhiwe nge-ultrasound ultrasound.
Ngokungafani nendawo evamile futhi ephephile emibili ngesimo somfanekiso omnyama omnyama nesigcwele esibukweni, okungenakuqondakala isiguli, i-4 d ultrasound ye-fetus iyinhlobo ye-ultrasound ngesimo se-3 d. Ngakho-ke, ivame ukubizwa ngokuthi i-3d video ultrasound. Futhi uma i-3D ultrasound, umthamo nesithombe sombala we-fetus ngezilinganiso ezintathu "ubude / ukuphakama / ukujula," ku-static, bese-4 d ultrasound ekukhulelweni kunesilinganiso sesine - "isikhathi", okungekho ngaphezu kwemininingwane encane yokubukeka kwengane, phakathi neseshini I-Ultrasound ingacatshangwa ngokuhamba kwayo ku-inthanethi. Ngaphezu kwalokho, ukurekhodwa kwedatha ye-ultrasound ekukhulelweni kwamafomethi e-3d no-4d ku-disk noma ikhadi le-flash ngesimo sevidyo kliphu noma ngisho nesithombe esilula kuzoqinisekisa ukuthi abazali abazayo nezihlobo zabo bazothola futhi balondoloze ukubonakala okugqamile kokuqala kwemihlangano ngemivimbo isikhathi eside.
Kodwa umsebenzi we-4d ultrasound we-fetus, njengezinhlobonhlobo ze-ultrasound ezintathu-dimensional, ngaphandle kwesifiso sokuvinjelwa kanye nesifiso somama ukuze wazi kangane nengane yakhe esibelethweni, futhi kulamaphuzu abalulekile okuxilongwa:
- ukuhlonza izinkinga ezingaphandle zentuthuko yangaphandle ("umlomo wempuphu", "hare lip", izinkinga nomthambo womgogodla);
- okungafani kakhulu, okunembile futhi okusheshayo okungafani ne-2d ultrasound, ukutholakala kokungafani kwe-chromosomal ye-embryo (ukugwema iphutha lokuxilonga ekulinganisweni kwefolda yomlomo wesibeletho, ukuhlolwa kwethambo lomzimba);
- ukutholakala kwezimo eziphuthumayo zesimiso sezinzwa ezisemkhatsini ngenxa yokuthi kungenzeka ukuvuselela ama-ventricles obuchopho bombungu kakade ku-trimester yokuqala;
- ukuxilongwa kweziphambeko zenhliziyo ezibangelwa ukuzalwa (ukwethembela okuncane kokusebenza komdokotela kunokwenziwa kwe-ultrasound evamile, i-on-line mode ivumela ukuhlola umsebenzi wenhliziyo esigabeni ngasinye somjikelezo wenhliziyo);
- ukuboniswa kwemininingwane yamathambo e-fetal, ubude, ukulinganisa kwamalungu, isisindo somgogodla, imifino neminwe kanye nezinzwani ngokukhetha ukuvuselelwa kwamathambo;
- ukubuka ubuso obusweni bomntwana, okubonisa ukuthi khona / ukungabikho kwezinkinga ekuthuthukiseni kwayo;
- ukuzimisela okungenakunqunywa kobulili bomntwana ngenxa yokubonakala okuphezulu kwezitho zangasese.
Okusemandleni okuqhuba i-4d ultrasound ngesikhathi sokukhulelwa kuyisikhathi samasonto angu-10-28. Phakathi nalesi sikhathi, umntwana osencane angakwazi ukuhamba ngokukhululekile emanzini amniotic esibelethweni sikamama, okuvumela ukuba ngeso lengqondo ngeso lengqondo futhi umsebenzi wezinhlelo zawo. Lapho "ukuguga" okungaphezulu, ngokuvamile bekulungisa isikhundla sabo ngeminyango yabo ensikeni, ukuthola isithombe sekhwalithi semvuthu kungabangela inkinga.
