Ubuvuzi Ultrasound

Twese tuzi ko igikoresho cyo gusuzuma ultrasonic gitanga ibyabaye ultrasonic waves (ikwirakwiza imiraba) kandi ikakira imiraba ya ultrasonic (echo waves) ikoresheje iperereza.Nigice cyingenzi cyibikoresho byo gusuzuma, nkamaso yimashini ya B-ultrasound, kandi ihujwe numubiri wumuntu nibikoresho.giciriritse.

Inshingano ya ultrasound probe nuguhindura ibimenyetso byamashanyarazi mubimenyetso bya ultrasonic cyangwa ubundi.Iperereza rirashobora kwanduza no kwakira ultrasound, no gukora electro-acoustic na signal ihinduka.Irashobora guhindura ibimenyetso byamashanyarazi byoherejwe na nyirarureshwa mu kimenyetso cyinshi cya oscillating signal ultrasonic signal, kandi irashobora kandi guhindura ibimenyetso bya ultrasonic bigaragarira inyuma mubice hamwe ningingo mubimenyetso byamashanyarazi.kuri monitor ya mudasobwa yakiriye.Ultrasonic probe ikorwa hifashishijwe iri hame ryakazi.Muri rusange, ihindura ibimenyetso byamashanyarazi bitangwa na ultrasound mumajwi yumurongo mwinshi kandi ikayinyuza mumubiri wumuntu, hanyuma igahindura ibimenyetso byerekanwe mubimenyetso byamashanyarazi ikabigaragaza kuri ecran yabakiriye, kimwe na baleine.Imirasire ya ultrasonic isohoka mu nyanja ni nkibibabi byerekana intera yibintu byerekana imiraba yijwi nijoro.

Wafer imbere muri probe irashobora kubyara ibintu byoroshye munsi yumuriro, bityo bikabyara amajwi ya ultrasonic;muburyo bunyuranye, iyo ultrasonic amajwi yumurongo inyuze muri wafer, irashobora kandi gutera ihinduka rya elastique, nayo igatera impinduka za voltage, hanyuma ikanyura mu kibaho cyo gutunganya ibimenyetso gitunganya ibimenyetso byamashanyarazi bihuye kugirango irangize ishusho yikintu cyamenyekanye. .Ubu buryo bwo gutunganya bwitwa ingaruka za piezoelectric (ingaruka nziza kandi zinyuranye za piezoelectric).

Ikoreshwa rya ultrasound zisanzwe mubice bitandukanye ：

Gukoresha convex array probe (3.5MHz) mubyara no kubyara ndetse na hepatobiliary, pancreas, impyiko nimpyiko

Umurongo wa array array (3.5MHz) kugirango ukoreshe imiyoboro y'amaraso n'ingingo nto
