Ultrasound probes chinhu chakakosha che ultrasound system.
Basa rayo rakanyanya kukosha nderekuwana shanduko yepakati pakati pesimba remagetsi uye acoustic simba, ndiko kuti, inogona kushandura ese emagetsi simba kuita acoustic simba uye acoustic simba kuita magetsi emagetsi.Chinhu chakakosha chinopedzisa iyi nhevedzano yeshanduko ndiyo Piezoelectric crystal.Iyo crystal imwe chete yakanyatsochekwa kuita chimwe chinhu (Element) uye yakarongedzwa muhurongwa hwejometri array.
Probe inogona kunge iine mashoma semakumi uye akawanda anosvika makumi ezviuru zvezvinhu zvakarongwa.Imwe neimwe array element ine 1 kusvika ku3 mauniti.
Kuti unakidze zvinhu zvakarongeka kugadzira mafungu e ultrasonic uye kutora masaini emagetsi emagetsi, waya dzinofanirwa kusungirirwa kune rimwe nerimwe boka rezvinhu zvakarongwa.
Kana akashandiswa zvisizvo, majoini e solder anogona kukanganiswa zviri nyore nekupinda couplant kana kutyorwa nekudengenyeka kwakanyanya.
Kuti utungamirire iyo ultrasonic beam kunze kwekuferefeta zvakanaka, iyo acoustic impedance (iyo dhigirii yekuvharira kune iyo ultrasonic wave) munzira yeacoustic beam inofanirwa kugadziridzwa kusvika padanho rakafanana neganda remunhu-pamberi pezvinhu zvakawanda. , wedzera akawanda akaturikidzana ezvakaumbwa zvinhu.Iyi layer ndiyo yatinoti matching layer.Chinangwa cheichi ndechekuve nechokwadi chepamusoro dhigirii reiyo ultrasound imaging mhando uye kubvisa zvigadzirwa zvinokonzerwa nepamusoro impedance ratios.Tichangobva kuona kubva kudhiyagiramu yemaitiro ekuongorora kuti iyo yekunze dhizaini ine zita risinganzwisisike rekuti Lenzi.Kana iwe ukafunga nezve kamera lens, wakarurama!
Kunyangwe isiri girazi, iyi layer yakaenzana negirazi lenzi yeiyo ultrasound danda (iyo inogona kufananidzwa nedanda) uye inoshanda chinangwa chimwechete-kubatsira ultrasound kutarisisa.Iyo element uye lens layer yakanyatso kuteedzerwa pamwechete.Hapafaniri kuva neguruva kana tsvina.Tisingatauri nezvemhepo.Izvi zvinoratidza kuti kuongorora kwatinobata mumaoko edu zuva rose chinhu chakapfava uye chakapfava!Zvibate zvinyoro.Iyo yekufananidza layer uye iyo lens layer inonyanya kukoshesa nezvazvo.Hazvifanirwe kungotsvaga mamwe ma sticker erabha.Pakupedzisira, kuitira kuti probe ishande zvakatsiga uye zvachose, inofanira kuiswa munzvimbo yakavharwa.Tungamira kunze waya uye ubatanidze kune socket.Sezvakangoita probe yatinobata mumaoko edu uye tinoishandisa mazuva ese.
Zvakanaka, zvino zvatava nekunzwisisa kwekutanga kwekuongorora, mukushandiswa kwezuva nezuva tinoedza kuumba tsika yakanaka yekumuda.Tinoda kuti ive nehupenyu hwakareba, hunobudirira, uye hushoma hushoma.Neshoko rimwe, tishandire isu.Saka, chii chatinofanira kungwarira zuva nezuva?Bata zvinyoro, usaputike, usaputse waya, usapeta, usaite Freeze kana isina kushandiswa Mumamiriro echando, mugadziri anodzima yakakwira voltage kune array element.Iyo crystal unit haisisiri oscillates uye probe inomira kushanda.Iyi tsika inogona kunonoka kuchembera kwekristaro unit uye kuwedzera hupenyu hweprobe.Isai probe isati yaitsiva.Kiya probe zvinyoro nyoro pasina kusiya couplant.Kana usingashandisi probe, pukuta couplant.Dzivirira kubuda, corrosion elements uye solder joints.Chengetedzo inofanira kutorwa mukuuraya utachiona Makemikari akadai semishonga inouraya utachiona uye maajenti ekuchenesa anogona kukonzera lenzi uye kutungamirira mashefu erabha kukwegura uye kuita brittle.Pakunyudza nekuuraya utachiona, dzivirira kubata pakati peprobe socket nemushonga wekuuraya utachiona.
