Ukuhlelwa kweeprobes ze-ultrasound zonyango

Iprobe ye-Ultrasonic (iprobe ye-ultrasonic) yinxalenye ebalulekileyo yesixhobo sokuxilonga se-ultrasonic.Ayinakuguqula kuphela imiqondiso yombane kwimiqondiso ye-ultrasound, kodwa iphinde iguqule imiqondiso ye-ultrasound ibe yimiqondiso yombane, oko kukuthi, inemisebenzi emibini yokuhanjiswa kwe-ultrasound kunye nokwamkela.

Ukuhlelwa kweeprobes ze-ultrasound zonyango

Ubume kunye nohlobo lweprobe ye-ultrasound, kunye neemeko zeparameters ye-pulse excitation yangaphandle, umsebenzi kunye nemowudi yokugxila, ube nobudlelwane obukhulu kunye nokuma kwe-ultrasound beam ephumayo, kwaye kwakhona ube nobudlelwane obukhulu kunye nokusebenza, umsebenzi, kunye nomgangatho wezixhobo zokuxilonga ze-ultrasound.Isixhobo se-transducer sinobudlelwane obuncinci kunye nokumila kwe-ultrasound beam;nangona kunjalo, ukusebenza kakuhle kwe-piezoelectric, uxinzelelo lwesandi, ukuqina kwesandi kunye nomgangatho wokucinga wokukhutshwa kwayo kunye nokwamkelwa kunxulumene ngakumbi.

I-Pulse echo probe:

Iprobe enye: Idla ngokukhetha iiseramikhi zepiezoelectric eziphantsi kwecwecwe elicaba njenge-transducer.Ugxininiso lwe-Ultrasound ludla ngokuthatha iindlela ezimbini: iqokobhe elibhityileyo elingqukuva okanye i-transducer emise okwesitya esebenzayo egxile kunye necwecwe elicwengileyo lediskhi yokuthandana ligxile.Ngokuqhelekileyo isetyenziswe kuhlobo lwe-A, uhlobo lwe-M, i-fan mechanical scan kunye ne-pulse Doppler ultrasonic diagnostic equipment.

Mechanical probe: Inani leetshiphusi zombane ezicinezelweyo kunye nemowudi yentshukumo inokwahlulwa ibe ziindidi ezimbini: iyunithi ye-transducer ebuyisela ukuskena ujingi kunye ne-multi-element transducer ejikelezayo yokutshintsha ukuskena probe.Ngokweempawu zomahluko wendiza yokuskena, inokwahlulwa ngokwecandelo lokuskena, iskena se-panoramic radial kunye ne-rectangular plane yelinear scan probe.

Iprobe ye-elektroniki: Yamkela ubume bezinto ezininzi kwaye isebenzisa umgaqo wobuchwephesha ukwenza iskena se-beam yesandi.Ngokwesakhiwo kunye nomgaqo-nkqubo wokusebenza, unokwahlulwa kumgca womgca, umgca we-convex kunye neprobe yoluhlu olunezigaba.

I-Intraoperative probe: Isetyenziselwa ukubonisa isakhiwo sangaphakathi kunye nesikhundla sezixhobo zotyando ngexesha lokusebenza.Yiprobe ye-frequency ephezulu ene-frequency ye-7MHz.Ineempawu zobukhulu obuncinci kunye nesisombululo esiphezulu.Ineentlobo ezintathu: uhlobo lokuskena koomatshini, uhlobo lwe-convex uluhlu kunye nohlobo lolawulo lwengcingo.

I-Puncture probe: Idlula kwi-cavity yomzimba ehambelanayo, inqanda igesi yemiphunga, igesi yesisu kunye nezicubu zethambo ukuze usondele kwizicubu ezinzulu ukuze zihlolwe, ziphucule ukubonwa kunye nesisombululo.Okwangoku, kukho iiprobes ze-transrectal.

I-Transurethral probe, i-transvaginal probe, i-transesophageal probe, i-gastroscopic probe kunye ne-laparoscopic probe.Ezi probe ziyi-mechanical, wire-controlled okanye uhlobo lweconvex;zineengile ezahlukeneyo ezimile okwefeni;uhlobo lwenqwelomoya enye kunye nodidi lweenqwelomoya ezininzi.I-frequency iphezulu kakhulu, ngokubanzi malunga ne-6MHz.Kwiminyaka yakutshanje, iiprobes ze-transvascular ezinobubanzi obungaphantsi kwe-2mm kunye ne-frequency ngaphezulu kwe-30MHz ziye zaphuhliswa.

I-Intracavitary probe: Idlula kwi-cavity yomzimba ehambelanayo, igwema i-gas ye-lung, i-gas yesisu kunye ne-bone tissue ukuze isondele kwizicubu ezinzulu ukuze zihlolwe, ziphucule ukubonwa kunye nesisombululo.Okwangoku, kukho i-transrectal probes, i-transrethral probes, i-transvaginal probes, i-transesophageal probes, i-gastroscopic probes kunye ne-laparoscopic probes.Ezi probe ziyi-mechanical, wire-controlled okanye uhlobo lweconvex;zineengile ezahlukeneyo ezimile okwefeni;uhlobo lwenqwelomoya enye kunye nodidi lweenqwelomoya ezininzi.I-frequency iphezulu kakhulu, ngokubanzi malunga ne-6MHz.Kwiminyaka yakutshanje, iiprobes ze-transvascular ezinobubanzi obungaphantsi kwe-2mm kunye ne-frequency ngaphezulu kwe-30MHz ziye zaphuhliswa.

I-Doppler probe

Ikakhulu isebenzisa isiphumo se-Doppler ukulinganisa iiparamitha zokuhamba kwegazi, kunye nokuxilongwa kwezifo zentliziyo, kwaye ingasetyenziselwa ukubeka iliso kumntwana.Ikakhulu yahlulwe kwezi ntlobo zintathu zilandelayo:

1. Continuous wave Doppler probe: Uninzi lwe-transmitter kunye ne-receiver chips ziyahlukana.Ukuze wenze i-Doppler probe eqhubekayo ibe novakalelo oluphezulu, ngokubanzi akukho bloko lokufunxa liyongezwayo.Ngokokusetyenziswa okwahlukileyo, indlela yokwahlula i-chip kunye ne-chip yokufumana i-Doppler probe eqhubekayo nayo yahlukile.

2. I-Pulse wave Doppler probe: Ulwakhiwo ngokuqhelekileyo lufana ne-pulse echo probe, usebenzisa i-wafer yoxinzelelo olulodwa, kunye nomgca ohambelanayo kunye nebhloko yokufunxa.

3. Iprobe emile okwePlum: Ubume bayo bugxile kwitshiphu enye kuphela, kunye neetshiphusi ezintandathu ezisingqongileyo, zicwangciswe ngokwemilo yentyatyambo yeplam, esetyenziselwa ukujonga umntwana ongekazalwa kunye nokufumana ukubetha kwentliziyo yomntwana.
