Munhu anenge achida kuziva, uye kunyange kuvakadzi vane pamuviri. Pasina mubvunzo, amai vese vemangwana vanobvunzwa zuva rega nemibvunzo pamusoro pezvinoita mwana wavo mumumhino, zvinoratidzika sei, zvavanoita pane imwe nguva, nezvimwe. Nenzira yakanaka, sayenzi uye teknolojia hazvimire, uye, kuitira kuchengetedza runyararo rwepfungwa, kune mhinduro dzemibvunzo yose inofarira vakadzi vane pamuviri uye kwete chete yakagadzirwa ne-dimensional ultrasound.
Kusiyana neinoyevedza uye yakachengetedzwa maviri-dimensional mufananidzo wepachena mutsvuku nemufananidzo mutsvuku, pasingafungi kumurwere, 4 d ultrasound ye fetus ishoko re ultrasound muchimiro che 3 d. Saka, inowanzozonzi 3d video ultrasound. Uye kana iyo 3D ultrasound, ivhu uye mufananidzo we fetus muhupamhi hutatu "urefu / urefu / kukwirira," iine static, uye 4 d ultrasound pakuberekwa ine chechina-"nguva", iyo, kunze kwezvinhu zviduku zvikuru zvekuoneka kwechecheche, panguva Ultrasound inogonawo kufungwa nezvekufamba kwayo pa-line. Uyezve, kurekodzwa kwemashoko e-ultrasound pakuberekwa mu 3d ne 4d mafomu pa diski kana kadi yekutsvaga iri mufananidzo wevhidhiyo kana kunyange mufananidzo wakajeka uchaita kuti vabereki vekupedzisira uye hama dzavo vagamuchire uye vachengetedze maonero akajeka emisangano yekutanga nemakumbo kwenguva refu.
Asi basa 4d ultrasound ye fetus, semhando dzakasiyana-siyana-tatu-dimensional ultrasound, kunze kwechibvumirano chechibvumirano uye chido chaamai kuti vazive mwana wavo muchizvaro, zvakare mune zvinotevera zvinoratidzirwa pfungwa:
- chizivo chekunze kwekukurumidza anomalies ("mhumhi muromo", "hare lip", zvinetso nemutsara wemutsara);
- iyo inoshanda zvikuru, yakarurama uye yakatsanya isina kufanana ne2d ultrasound, kuonekwa kwechromosomal kusagadzikana kwemu embryo (kudzivisa kuongororwa kwepfungwa muchiyero chemuviri wechiberekero, kuongororwa kwepfupa remapfupa);
- kuonekwa kwekusaziva kwepakati yenheyo yepamusoro nekuda kwekwaniso yekugadzirisa mhepo yeuropi yeuropi yekembryo yakatova mumutatu wekutanga;
- kuongororwa kwepenital heart defects (kusaderera pane unyanzvi hwechiremba kudarika neyakakurumbira ultrasound, on-line mode inobvumira kuongorora basa remwoyo mune chimwe chikamu chemuviri wepfungwa);
- kuonekwa kwemashoko e fetal bones, kureba, kuenzanisa kwemakumbo, maruva emasana, masaya neminwe uye zvigunwe zvine chisarudzo chekuvakazve masaga;
- kutarisa kwechitarisiko chemaziso emucheche, zvichiratidza kuvapo / kusavapo kwematambudziko mukugadzirwa kwayo;
- kusarudza kusinganzwisisiki kwehupombwe hwemucheche nekuda kwekuonekwa kwakanyanya kwepabonde.
Iyo yakanakisisa yekuitisa 4d ultrasound pakuberekwa inguva yevhiki 10-28. Munguva iyi, mwana muduku akadaro anogona kuramba achifamba akasununguka mumvura yeamniotic mudumbu raamai, iyo inobvumira kugadzirisa maonero uye basa rehurongwa hwayo. Pane imwe "kukwegura", kazhinji kugadzirisa nzvimbo yavo nemasana avo kune sensor, kuwana chimiro chakanaka chemakumbo kunogona kuoma.
