Kuthiwani Uyini umshini we-Ultrasound? --- https://hv-caps.biz
I-Ultrasound noma i-ultrasonography iyindlela yezithombe yezokwelapha esebenzisa amagagasi omsindo aphakeme kakhulu nama-echoes awo. Le ndlela ifana nokwenziwa kwesikhumba okusetshenziswa amalulwane, imikhomo namahlengethwa, kanye ne-SONAR esetshenziswa yimikhumbi-ngwenya.
Ku-ultrasound, izehlakalo ezilandelayo ziyenzeka:
Umshini we-ultrasound udlulisa imiphimbo yomsindo ophezulu (1 kuye ku-1 megahertz) emzimbeni wakho usebenzisa iphenyo.
Amagagasi omsindo angena emzimbeni wakho ashaye umngcele phakathi kwezicubu (isb. Phakathi kwezicubu ezinamanzi nezithambile, izicubu ezithambile nethambo).
3. Amanye amaza omsindo akhonjiswa emuva kuphenyo, kanti amanye aqhubeka aze afike komunye umngcele futhi abonakale.
Amagagasi akhonjisiwe athathwa yiphenyo futhi adluliselwe emshinini.
5.Umshini ubala ibanga ukusuka kuphenyo kuya ezicutshini noma esithweni (imingcele) kusetshenziswa ijubane lomsindo kuzicubu (5,005 ft / s noma1,540 m / s) nesikhathi sokubuya kwe-echo ngayinye (imvamisa ku-oda of millionths womzuzwana).
6.Umshini ukhombisa amabanga namandla we-echoes esikrinini, kwakheke isithombe sobukhulu obufana nalona oboniswe ngezansi.
Ku-ultrasound ejwayelekile, izigidi zamapulse nama-echoes ziyathunyelwa futhi zamukelwe umzuzwana ngamunye. Uphenyo lungahanjiswa ebusweni bomzimba bese lubekwe engele ukuthola ukubukwa okuhlukahlukene.
