Itekhnoloji ye-ultrasound yezonyango iqhubele phambili kwaye okwangoku idlala indima ebalulekileyo ekuxilongeni nasekunyangeni izigulana. Uphuhliso lwetekhnoloji ye-ultrasound lusekelwe kwimbali enomdla ethatha iminyaka engaphezu kwama-225. Olu hambo lubandakanya igalelo labantu abaninzi kwihlabathi liphela, kuquka abantu kunye nezilwanyana.
Masihlolisise imbali ye-ultrasound size siqonde indlela amaza esandi abe sisixhobo esibalulekileyo sokuxilonga ngayo kwiikliniki nakwizibhedlele kwihlabathi liphela.
Ukuqala Kwasekuqaleni Kwe-Echolocation kunye ne-Ultrasound
Umbuzo oqhelekileyo ngulo, ngubani owasungula i-ultrasound? Isazi sebhayoloji sase-Itali uLazzaro Spallanzani udla ngokubizwa ngokuba nguvulindlela wovavanyo lwe-ultrasound.
ULazzaro Spallanzani (1729-1799) wayengusosayensi wefiziyoloji, uprofesa, kunye nomfundisi oye wenza iimvavanyo ezininzi ezachaphazela kakhulu uphando lwebhayoloji ebantwini nakwizilwanyana.
Ngo-1794, uSpallanzani wafunda ngamalulwane waza wafumanisa ukuba ayesebenzisa isandi endaweni yokubona, inkqubo ngoku eyaziwa ngokuba yi-echolocation. I-Echolocation ibandakanya ukufumana izinto ngokubonakalisa amaza esandi kuzo, umgaqo oxhasa ubuchwepheshe be-ultrasound yezonyango zanamhlanje.
Iimvavanyo zokuqala ze-Ultrasound
Kwincwadi kaGerald Neuweiler ethi *Bat Biology,* ubalisa ngovavanyo lukaSpallanzani ngeempungutye, ezazingenakubhabha ebumnyameni ngaphandle komthombo wokukhanya. Nangona kunjalo, xa kwakwenziwa uvavanyo olufanayo ngeempungutye, zabhabha ngokuzithemba zijikeleza igumbi, ziphepha imiqobo nokuba kumnyama bhuqe.
USpallanzani wade wenza iimvavanyo apho wayebamfamekisa khona amalulwane ngokusebenzisa “iinaliti ezishushu kakhulu,” kodwa aqhubeka nokuphepha imiqobo. Wagqiba oku kuba iingcingo zazineentsimbi ezinamathele eziphelweni zazo. Wafumanisa nokuba xa wayevala iindlebe zamalulwane ngeetyhubhu zethusi ezivaliweyo, ayelahlekelwa kukwazi kwawo ukuhamba ngendlela efanelekileyo, nto leyo eyamenza wagqiba kwelokuba amalulwane ayexhomekeke kwisandi sokuhamba.
Nangona uSpallanzani wayengaqondi ukuba izandi ezenziwa ziintaka zazizezokuqondisa kwaye zazingaphaya kokuviwa ngabantu, wagqiba ngokuchanekileyo ukuba iintaka zazisebenzisa iindlebe zazo ukuqonda indawo ezikuyo.
Uphuhliso lweTekhnoloji ye-Ultrasound kunye neeNzuzo zayo zonyango
Emva komsebenzi kaSpallanzani wokuqala, abanye bakha phezu kweziphumo zakhe. Ngo-1942, ingcali yezifo zengqondo uCarl Dusik waba ngowokuqala ukusebenzisa i-ultrasound njengesixhobo sokuxilonga, ezama ukudlulisa amaza e-ultrasound kwi-skull yomntu ukuze abone iithumba zobuchopho. Nangona eli yayilinqanaba lokuqala kwi-sonography yezonyango yokuxilonga, yabonisa amandla amakhulu obu buchwepheshe obungenalo uhlaselo.
Namhlanje, iteknoloji ye-ultrasound iyaqhubeka nokukhula, kunye nophuhliso oluqhubekayo kwizixhobo kunye neenkqubo. Kutshanje, uphuhliso lwee-scanner ze-ultrasound eziphathekayo zenze kwaba nokwenzeka ukusebenzisa obu buchwepheshe kwiindawo ezahlukeneyo kunye nezigaba zokhathalelo lwezigulane.
