Itondekanya ryubuvuzi ultrasound

Ultrasonic probe (ultrasonic probe) nigice cyingenzi cyingenzi mugikoresho cyo gusuzuma ultrasonic.Ntishobora guhindura ibimenyetso byamashanyarazi gusa mubimenyetso bya ultrasound, ahubwo irashobora no guhindura ibimenyetso bya ultrasound mubimenyetso byamashanyarazi, ni ukuvuga ko ifite imirimo ibiri yo kohereza ultrasound no kwakira.

Itondekanya ryubuvuzi ultrasound

Imiterere nubwoko bwa ultrasound probe, kimwe nuburyo ibintu byimbere yimpimbano yo hanze, akazi nuburyo bwo kwibandaho, bifitanye isano ikomeye nimiterere yibiti bya ultrasound isohora, kandi bifite isano ikomeye nibikorwa, imikorere, hamwe nubuziranenge bwibikoresho byo gusuzuma ultrasound.Ibikoresho bya transducer bifitanye isano rito nuburyo bwa ultrasound;icyakora, piezoelectric ikora neza, umuvuduko wijwi, ubukana bwijwi hamwe nubwiza bwamashusho yibisohoka no kwakirwa bifitanye isano.

Impanuka ya echo probe:

Probe imwe: Mubisanzwe ihitamo piezoelectric ceramics yubutaka muri disiki yoroheje nka transducer.Ultrasound yibanda mubisanzwe ikoresha uburyo bubiri: igishishwa cyoroshye cyangwa isahani isa na transducer ikora yibanda cyane hamwe na disiki yoroheje ya disiki yerekana amajwi-yo gukundana yibanda.Bikunze gukoreshwa muburyo bwa A, M-ubwoko, imashini yumukanishi scan hamwe na pulse Doppler ultrasonic ibikoresho byo gusuzuma.

Ubushakashatsi bwa mashini: Umubare wibikoresho byamashanyarazi bikanda hamwe nuburyo bwo kugenda birashobora kugabanywa muburyo bubiri: transducer yingingo isubiza swing scanning hamwe nibintu byinshi-transducer bizunguruka guhinduranya scanning probe.Ukurikije ibiranga indege itandukanya scan, irashobora kugabanywamo ibice byo gusikana, panoramic radial scan hamwe nindege y'urukiramende umurongo wa scan probe.

Ubushakashatsi bwa elegitoronike: Ifata ibintu byinshi kandi ikoresha ihame rya elegitoroniki kugirango ikore amajwi ya scan.Ukurikije imiterere nihame ryakazi, birashobora kugabanywa kumurongo ugizwe umurongo, umurongo wa convex hamwe nicyiciro cya array probe.

Intraoperative probe: Ikoreshwa mukugaragaza imiterere yimbere nu mwanya wibikoresho byo kubaga mugihe cyo kubaga.Nubushakashatsi bwihuse cyane hamwe na 7MHz.Ifite ibiranga ubunini buto kandi bukomeye.Ifite ubwoko butatu: ubwoko bwa scanning scan, ubwoko bwa convex array nubwoko bwo kugenzura insinga.

Iperereza rya poncure: Rinyura mu cyuho cyumubiri gihuye, rikirinda gaze ibihaha, gaze gastrointestinal na tissue yamagufa kugirango wegere urugingo rwimbitse rugomba gusuzumwa, rutezimbere kandi rukemurwe.Kugeza ubu hariho iperereza ryihuse,

Transurethral probe, transvaginal probe, transesophageal probe, gastroscopic probe na laparoscopic probe.Iperereza ni imashini, igenzurwa ninsinga cyangwa ubwoko bwa convex array;ufite impande zitandukanye zisa nabafana;ubwoko bumwe bw'indege n'ubwoko bwinshi bw'indege.Inshuro ni ndende, muri rusange hafi 6MHz.Mu myaka yashize, ubushakashatsi bwakozwe na transvasculaire ifite diameter iri munsi ya 2mm hamwe numurongo uri hejuru ya 30MHz.

Ipracavitar probe: Iranyura mu cyuho cyumubiri gikwiranye, ikirinda gaze ibihaha, gaze gastrointestinal na tissue yamagufa kugirango yegere ingirangingo zimbitse zigomba gusuzumwa, zinonosore imenyekanisha no gukemura.Kugeza ubu, hariho inzira ya transrectal, transurethral probes, transvaginal probes, transesophageal probes, gastroscopic probes na laparoscopic.Iperereza ni imashini, igenzurwa ninsinga cyangwa ubwoko bwa convex array;ufite impande zitandukanye zisa nabafana;ubwoko bumwe bw'indege n'ubwoko bwinshi bw'indege.Inshuro ni ndende, muri rusange hafi 6MHz.Mu myaka yashize, ubushakashatsi bwakozwe na transvasculaire ifite diameter iri munsi ya 2mm hamwe numurongo uri hejuru ya 30MHz.

Doppler probe

Ikoresha cyane cyane ingaruka ya Doppler mugupima ibipimo byamaraso, hamwe no gusuzuma indwara zifata umutima, kandi birashobora no gukoreshwa mugukurikirana uruhinja.Ahanini ugabanijwemo ubwoko butatu bukurikira:

1. Umuhengeri uhoraho Doppler probe: Byinshi mu byuma byohereza no kwakira imashini biratandukanye.Kugirango ukore umuraba uhoraho Doppler probe ifite sensibilité yo hejuru, mubisanzwe ntakabuza kongeramo.Ukurikije imikoreshereze itandukanye, uburyo bwo gutandukanya chip yohereza hamwe na chip yakira yumurongo wikurikiranya Doppler probe nayo iratandukanye.

2. Impanuka ya pulse Doppler probe: Imiterere muri rusange ni kimwe na pulse echo probe, ukoresheje wafer yumuvuduko umwe, hamwe nigice gihuye nikibuza.

3. Ipima rimeze nk'ibibyimba: Imiterere yacyo ishingiye kuri chip imwe imwe yanduza, hamwe na bitandatu byakira imashini irizengurutse, bitunganijwe mu buryo bw'ururabyo, bikoreshwa mu gusuzuma uruhinja no kubona umuvuduko w'umutima.
