Itekhnoloji ye-ultrasound yezonyango ibone inkqubela phambili eqhubekayo kwaye ngoku idlala indima ebalulekileyo ekuxilongeni nasekunyangeni izigulana. Ukuphuhliswa kobuchwepheshe be-ultrasound busekelwe kwimbali enomdla ethatha iminyaka engama-225. Olu hambo lubandakanya iminikelo evela kubantu abaninzi kwihlabathi liphela, kuquka abantu nezilwanyana.
Makhe siphonononge imbali ye-ultrasound kwaye siqonde ukuba amaza omsindo abe sisixhobo esibalulekileyo soxilongo kwiiklinikhi nasezibhedlele kwihlabathi jikelele.
Ukuqala kwe-Echolocation kunye ne-Ultrasound
Umbuzo oqhelekileyo ngowokuba, ngubani owasungula i-ultrasound kuqala? Isazi sebhayoloji sase-Italiya uLazzaro Spallanzani sihlala sigqalwa njengovulindlela wovavanyo lwe-ultrasound.
ULazzaro Spallanzani (1729-1799) wayeyingcali yomzimba, unjingalwazi, kunye nomfundisi onovavanyo oluninzi lwaba nefuthe elikhulu kufundo lwebhayoloji ebantwini nakwizilwanyana.
Ngo-1794, uSpallanzani wafunda amalulwane waza wafumanisa ukuba ahambahamba esebenzisa isandi endaweni yokubona, inkqubo ngoku eyaziwa ngokuba yi-echolocation. I-echolocation iquka ukukhangela izinto ngokubonisa amaza esandi kuzo, umgaqo oxhasa ubugcisa bale mihla bezonyango beultrasound.
Iimvavanyo ze-Ultrasound zakwangoko
Kwincwadi kaGerald Neuweiler ethi *Bat Biology,* ubalisa ngamalinge kaSpallanzani ngezikhova, ezazingakwazi ukubhabha ebumnyameni kungekho mthombo wokukhanya. Nangona kunjalo, xa kwakwenziwa uvavanyo olufanayo ngamalulwane, ngokuzithemba abhabha ejikeleza igumbi, ephepha imiqobo nokuba kumnyama.
USpallanzani wada wenza novavanyo apho wawamfamekisayo amalulwane ngokusebenzisa “iinaliti ezibomvu ezishushu,” sekunjalo aqhubeka eyiphepha imiqobo. Wazimisela oku kuba ezi ngcingo zazinentsimbi ezincanyathiselwe emacaleni azo. Kwakhona wafumanisa ukuba xa evala iindlebe zamalulwane ngemibhobho yobhedu evaliweyo, ayengakwazi ukuhamba kakuhle, nto leyo eyabangela ukuba agqibe kwelokuba amalulwane axhomekeke kwisandi ukuze akwazi ukuhambahamba.
Nangona uSpallanzani engazange aqonde ukuba izandi ezazisenziwa ngamalulwane zezenzelwe ukuqhelaniswa nabantu, wayenyanisile wathi amalulwane ayesebenzisa iindlebe zawo ukuze akwazi ukubona izinto eziwangqongileyo.
I-Evolution ye-Ultrasound Technology kunye neeNzuzo zayo zonyango
Ukulandela umsebenzi wobuvulindlela kaSpallanzani, abanye bakhela phezu koko akufumanisileyo. Ngo-1942, ugqirha wemithambo-luvo uCarl Dusik waba ngowokuqala ukusebenzisa i-ultrasound njengesixhobo sokuxilonga, ezama ukudlulisa amaza e-ultrasound kukhakhayi lomntu ukuze abone amathumba ebuchotsheni. Nangona eli yayilinqanaba lokuqala kwi-sonography yezonyango, ibonise amandla amakhulu obu buchwepheshe bungangeneleliyo.
Namhlanje, iteknoloji ye-ultrasound iyaqhubeka nokuguquka, kunye nokuqhubela phambili okuqhubekayo kwezixhobo kunye neenkqubo. Kutshanje, ukuphuhliswa kweeskena ze-ultrasound eziphathekayo kwenze ukuba kube lula ukusebenzisa le teknoloji kwiindawo ezahlukeneyo kunye nezigaba zokunyamekela isigulane.
