Ukuhlukaniswa kwama-probes we-ultrasound yezokwelapha

I-Ultrasonic probe (i-ultrasonic probe) iyingxenye esemqoka ebalulekile yethuluzi lokuxilonga nge-ultrasonic.Awukwazi nje ukuguqula amasignali kagesi abe amasignali e-ultrasound, kodwa futhi uguqule amasignali e-ultrasound abe amasignali kagesi, okungukuthi, inemisebenzi emibili yokudluliselwa kwe-ultrasound nokwamukela.

Ukuhlukaniswa kwama-probes we-ultrasound yezokwelapha

Isakhiwo kanye nohlobo lwe-ultrasound probe, kanye nezimo zemingcele ye-pulse excitation yangaphandle, imodi yokusebenza kanye nemodi yokugxila, inobudlelwane obuhle nokuma kwe-ultrasound beam ephumayo, futhi futhi ibe nobuhlobo obuhle nokusebenza, umsebenzi, kanye nekhwalithi yemishini yokuxilonga ye-ultrasound.I-transducer element impahla inobudlelwano obuncane nokuma kwe-ultrasound beam;kodwa-ke, ukusebenza kahle kwe-piezoelectric, ukucindezela komsindo, ukushuba komsindo kanye nekhwalithi yokucabanga yokuphuma kwayo nokwamukela kuhlobene kakhulu.

I-Pulse echo probe:

I-probe eyodwa: Ivamise ukukhetha i-piezoelectric ceramics egaywe ibe yidiski eliyisicaba elincanyana njenge-transducer.Ukugxila kwe-Ultrasound kuvame ukusebenzisa izindlela ezimbili: igobolondo elincanyana eliyindilinga noma i-transducer emise okwesitsha esebenzayo egxilile kanye nelensi eyisicaba ye-disc yokuqomisana egxile.Okuvame ukusetshenziswa kuhlobo lwe-A, uhlobo lwe-M, ukuskena kwabalandeli bemishini kanye nemishini yokuxilonga ye-Doppler ye-pulse.

I-Mechanical probe: Inombolo yama-chips kagesi acindezelwe kanye nemodi yokunyakaza ingahlukaniswa ngezinhlobo ezimbili: i-unit transducer ephindaphindayo iskena sokushwiba kanye ne-multi-elementi ye-transducer ejikelezayo eshintshayo yokuskena uphenyo.Ngokuya ngezici zendiza yomehluko wokuskena, ingahlukaniswa ngeskena somkhakha, iskena se-panoramic radial kanye nendiza engunxande ehlola umugqa wokuhlola.

I-Electronic probe: Yamukela ukwakheka kwezinto eziningi futhi isebenzisa umgomo we-elekthronikhi ukwenza ukuskena kwensimbi yomsindo.Ngokuya ngesakhiwo kanye nomgomo wokusebenza, ingahlukaniswa yaba umugqa womugqa, i-convex kanye ne-probe yohlu olunezigaba.

I-Intraoperative probe: Isetshenziselwa ukubonisa isakhiwo sangaphakathi kanye nesimo sezinsimbi zokuhlinza ngesikhathi sokuhlinzwa.Kuyi-high-frequency probe enemvamisa ecishe ibe ngu-7MHz.Inezici zobukhulu obuncane kanye nokulungiswa okuphezulu.Inezinhlobo ezintathu: uhlobo lokuskena komshini, uhlobo lwe-convex array kanye nohlobo lokulawula izintambo.

I-Puncture probe: Idlula emgodini womzimba ohambisanayo, igwema igesi yamaphaphu, igesi yamathumbu kanye nezicubu zethambo ukuze isondele esicutshini esijulile ukuze ihlolwe, ithuthukise ukutholakala nokuxazulula.Njengamanje kukhona ama-transrectal probes,

I-Transurethral probe, i-transvaginal probe, i-transesophageal probe, i-gastroscopic probe kanye ne-laparoscopic probe.Lawa ma-probe awumshini, olawulwa ngocingo noma uhlobo lwe-convex;babe nama-engeli ahlukene amise okwefeni;uhlobo lwendiza eyodwa kanye nohlobo lwezindiza eziningi.Imvamisa iphakeme kakhulu, ngokuvamile i-6MHz.Eminyakeni yakamuva, ama-transvascular probes anobubanzi obungaphansi kuka-2mm kanye nemvamisa engaphezu kuka-30MHz nawo athuthukile.

I-Intracavitary probe: Idlula emgodini womzimba ohambisanayo, igwema igesi yamaphaphu, igesi yamathumbu kanye nezicubu zamathambo ukuze isondele ezicubu ezijulile ezizohlolwa, ithuthukise ukutholakala nokuxazulula.Njengamanje, kukhona ama-transrectal probes, ama-transrethral probes, ama-transvaginal probes, ama-transesophageal probes, ama-gastroscopic probes kanye nama-laparoscopic probes.Lawa ma-probe awumshini, olawulwa ngocingo noma uhlobo lwe-convex;babe nama-engeli ahlukene amise okwefeni;uhlobo lwendiza eyodwa kanye nohlobo lwezindiza eziningi.Imvamisa iphakeme kakhulu, ngokuvamile i-6MHz.Eminyakeni yakamuva, ama-transvascular probes anobubanzi obungaphansi kuka-2mm kanye nemvamisa engaphezu kuka-30MHz nawo athuthukile.

I-Doppler probe

Ngokuyinhloko isebenzisa umphumela we-Doppler ukukala imingcele yokugeleza kwegazi, kanye nokuxilongwa kwezifo zenhliziyo, futhi ingasetshenziselwa ukuqapha ingane.Ihlukaniswe kakhulu ngezinhlobo ezintathu ezilandelayo:

1. I-wave wave Doppler probe: Iningi lama-transmitter nama-receiver chips ahlukene.Ukuze wenze i-wave wave Doppler probe ibe nokuzwela okuphezulu, ngokuvamile awekho ibhulokhi yokumuncwa engeziwe.Ngokusetshenziswa okuhlukile, indlela yokuhlukanisa i-chip yokudlulisa kanye ne-chip yokwamukela ye-wave wave Doppler probe nayo ihlukile.

2. I-Pulse wave Doppler probe: Isakhiwo ngokuvamile sifana ne-pulse echo probe, kusetshenziswa iwafa yokucindezela okukodwa, enongqimba oluhambisanayo kanye nebhulokhi yokumunca.

3. I-probe emise okwepulamu: Isakhiwo sayo sigxile kucwecwe olulodwa kuphela oludluliselayo, kanye nama-chips ayisithupha owamukelayo nxazonke, ahlelwe ngendlela ye-plum blossom, asetshenziselwa ukuhlola umbungu nokuthola ukushaya kwenhliziyo komntwana.
