ʻO ka ʻimi kani kani (ultrasonic probe) he ʻāpana koʻikoʻi koʻikoʻi o ka mea kani kani ultrasonic.ʻAʻole hiki iā ia ke hoʻololi wale i nā hōʻailona uila i nā hōʻailona ultrasound, akā hoʻololi pū i nā hōʻailona ultrasound i nā hōʻailona uila, ʻo ia hoʻi, loaʻa iā ia nā hana ʻelua o ka hoʻouna ʻana a me ka hoʻokipa.

Ka hoʻokaʻawale ʻana o nā mea noiʻi ultrasound olakino

ʻO ke ʻano a me ke ʻano o ka ultrasound probe, a me nā kūlana o nā ʻāpana pulse excitation waho, ka hana a me ke ʻano o ka nānā ʻana, he pilina maikaʻi loa me ke ʻano o ke kukuna ultrasound e hoʻopuka ai, a he pilina maikaʻi hoʻi me ka hana. ka hana, a me ka maikaʻi o ka mea hana diagnostic ultrasound.He liʻiliʻi ka pilina o ka mea transducer element me ke ʻano o ke kukuna ultrasound;akā naʻe,ʻoi aku ka pili o ka piezoelectric pono, ke kani kani, ka ikaika o ke kani a me ka maikaʻi o ke kiʻi.

Pulse echo probe:

Hoʻokahi ʻimi noiʻi: E koho maʻamau ʻo ia i nā ceramics piezoelectric i hoʻopaʻa ʻia i loko o kahi diski lahilahi e like me ka transducer.Hoʻohana maʻamau ka nānā ʻana i ke kani ʻana i nā ʻano ʻelua: ʻo ka ʻili lahilahi spherical a i ʻole ke ʻano kīʻaha transducer hoʻoikaika i ka nānā ʻana a me ka nānā ʻana i nā lens leo-dating lens.Hoʻohana maʻamau i ka A-type, M-type, mechanical fan scan and pulse Doppler ultrasonic diagnostic equipment.

Mechanical Probe: Hiki ke hoʻokaʻawale ʻia ka helu o nā ʻāpana uila i kaomi ʻia a me ke ʻano neʻe i ʻelua ʻano: unit transducer reciprocating swing scanning a me multi-element transducer rotating switching scanning probe.E like me nā hiʻohiʻona o ka mokulele ʻokoʻa scan, hiki ke hoʻokaʻawale ʻia i ka ʻāpana scan, panoramic radial scan a me rectangular plane linear scan probe.

Electronic probe: Hoʻohana ia i kahi hoʻolālā multi-element a hoʻohana i ka loina o ka uila e hana i ka nānā ʻana i ke kani kani.E like me ke ʻano a me ka loina hana, hiki ke hoʻokaʻawale ʻia i ka laina laina, convex array a me phased array probe.

Intraoperative probe: Hoʻohana ʻia ia e hōʻike i ke ʻano o loko a me ke kūlana o nā mea hana i ka wā o ka hana.He kiʻekiʻe-frequency probe me ka alapine o kahi o 7MHz.Loaʻa iā ia nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi a me ka hoʻonā kiʻekiʻe.He ʻekolu ʻano: ʻano scanning mechanical, convex array type and wire control type.

Puncture probe: Hele ia ma ka lua o ke kino e pili ana, e pale ana i ke kinoea māmā, ke kinoea gastrointestinal a me ka ʻiʻo iwi e hoʻokokoke i ka ʻiʻo hohonu e nānā ʻia, e hoʻomaikaʻi ana i ka ʻike a me ka hoʻonā.I kēia manawa aia nā ʻimi transrectal,

ʻO ka ʻimi transurethral, ​​ka ʻimi transvaginal, ka ʻimi transesophageal, ka ʻimi gastroscopic a me ka ʻimi laparoscopic.ʻO kēia mau probes he mechanical, wire-controlled a convex array type;loaʻa i nā kihi ʻokoʻa like ʻole;ʻano mokulele hoʻokahi a me nā ʻano mokulele he nui.He kiʻekiʻe ke alapine, ma kahi o 6MHz.I nā makahiki i hala iho nei, ua hoʻomohala ʻia nā ʻimi transvascular me ke anawaena ma lalo o 2mm a me ke alapine ma luna o 30MHz.

Intracavitary probe: Hele ia i loko o ka lua o ke kino e pili ana, e pale ana i ke kinoea māmā, ke kinoea gastrointestinal a me ka ʻiʻo iwi e hoʻokokoke i nā ʻiʻo hohonu e nānā ʻia, e hoʻomaikaʻi ana i ka ʻike a me ka hoʻonā.I kēia manawa, aia nā probes transrectal, transurethral probes, transvaginal probes, transesophageal probes, gastroscopic probes a me laparoscopic probes.ʻO kēia mau probes he mechanical, wire-controlled a convex array type;loaʻa i nā kihi ʻokoʻa like ʻole;ʻano mokulele hoʻokahi a me nā ʻano mokulele he nui.He kiʻekiʻe ke alapine, ma kahi o 6MHz.I nā makahiki i hala iho nei, ua hoʻomohala ʻia nā ʻimi transvascular me ke anawaena ma lalo o 2mm a me ke alapine ma luna o 30MHz.

ʻImi Doppler

Hoʻohana nui ia i ka hopena Doppler e ana i nā ʻāpana kahe o ke koko, a me ka ʻike ʻana i nā maʻi cardiovascular, a hiki ke hoʻohana ʻia no ka nānā ʻana i ka fetal.Hoʻokaʻawale nui ʻia i ʻekolu mau ʻano:

1. Hoʻomau ka nalu Doppler probe: Ua hoʻokaʻawale ʻia ka hapa nui o ka mea hoʻouna a me ka mea hoʻokipa.I mea e loaʻa ai ka ʻike kiʻekiʻe o ka ʻimi Doppler hawewe mau, ʻaʻole i hoʻohui ʻia kahi poloka absorption.E like me nā hoʻohana ʻokoʻa, ʻokoʻa ke ala o ka hoʻokaʻawale ʻana i ka chip transmitting a me ka loaʻa ʻana o ka chip o ka nalu hoʻomau Doppler probe.

2. Pulse wave Doppler probe: Ua like ka hale me ka pulse echo probe, me ka hoʻohana ʻana i ka wafer kaomi hoʻokahi, me kahi papa hoʻohālikelike a me kahi poloka absorption.

3. ʻAno Plum-Plum Probe: Aia kona ʻano me ka hoʻokahi wale nō chip transmitter, a ʻeono mau ʻāpana a puni, i hoʻonohonoho ʻia i loko o kahi ʻano pua plum, i hoʻohana ʻia e nānā i ka ʻōpū a loaʻa ka puʻuwai o ka fetal.
