Sonography. He aha te mea te reira me aha ko te pūtake o te tikanga rangahau

A, no te pā he rata te manawanui ki te ultrasound, e kore e te nuinga o whakatika maha rawa ngā pātai. Otiia ki te mea i te whakarite o whakamahia ngaro kupu "ultrasound", te mau uiraa ringihia ano he pī. Na, he tika te reira ki te matau, sonography - he aha te mea te reira? A i roto i ētahi wā, i homai te manawanui ko te ohipa rite.

Association

Ko te rōpū manawanui tuatahi hono ki moe, engari kahore ki te mahi ki a reira ultrasound kua. Ultrasound me sonography - rerekē ingoa mo te tukanga taua. Hoki te rangahau taua kei te te tahi mau taime whakamahia te ingoa o te sonography. I runga i tenei, ka taea e tatou te utu i te mutunga ohie: ultrasound, ultrasound, ultrasound - he aha te mea te reira? Ko tēnei ultrasound hua aromatawai o ngā tawhā morphological me mahi o okana me te kopa tangata.

I te mea ko te tikanga

tikanga Ultrasound i runga i nga āhuatanga o nga ngaru ultrasonic roto i te tinana ngaro. I roto i tetahi ora ngā te tinana o te kopa o te kiato rerekē, me te ātete. Ki te kitea tenei ultrasound te, refracted, marara whenumi ranei. Ka rite ki te hua, puta te whakapakoko pūrere tangohanga. Ko mau te tuhi o tohu vanavanaiki ultrasound kitea i te taonga.

taputapu Medical mō te ultrasound (sonography) whakamahi i te auautanga o 1.5 ki te 29 MHz. Ko te ware mōrahi e taea te mohio a e te taringa tangata, 20 kHz. Ko te whakapakoko hua - e kore e tika i te aratau o te ā-okana wheua ranei wahi rite x-hihi, me te mahere o ngā hanganga ā-.

whakamārama poto o mīhini ultrasound

Ki te whakahaere i te rangahau mā te whakamahi i mīhini ultrasound hauora. Sonography - he aha te mea te reira? Ahakoa ko te taua whakaaro katoa? He aha e nga mea timatanga ngā ratou o? Ko te mea pai i roto i te ultrasound taputapu pūrere kia matau ahupūngao. matau ratou he aha te mea te pānga piezoelectric, matau i roto i roa, wiri me iarere. manawanui noa nui ki te mohio e ngā te pūrere o te huānga e whai ake nei:

• he generator o ngaru ultrasonic, i.e. pini generator emitting me te wā kotahi te fariiraa i te tohu kitea;
• ultrasonic pūoko-transdyusora, e whare he maha nui o transducers pezokristallicheskih i roto i te pūoko reira ko te arotahi arotahi e taea ki a koe te arotahi ki runga i te hohonu e hiahiatia ana.

transdyusorov Types (pūoko)

whakamana ana te wehenga tuatahi kei i runga i te whakaaro mīhini, me te hiko. Matawai pūoko aunoa whakamana e te kaupapa o te pūmotu marama (hurihanga nekeneke ranei). Ko te drawback matua - iti taumira pikitia, wiri me te mahi e ngangau. sonography ultrasound Modern whakarere te tauira tawhito, hiahia ki te whakamahi i te putanga hiko.

pūoko Electronic he taputapu atu hou. whakapakoko scan whakaputaina e te tikanga hiko. Ko atu mārama, me te oti te pikitia. Noise me te wiri, ka mahi i te ngaro taputapu.

Kei te wehea matawai ultrasonic ki te momo rārangi, koropuku, me te rängai. Nä, ko te tono 3 momo o pūoko:

1. Paerangi. whakamahi te reira i te auau o 5-15 MHz. Ngä te rohe image uiui, ki te whakapakoko taumira teitei, hāngai uara okana ki te whanui o te pūoko, engari te matawai hohonu o kore ake atu i te 11 cm. He uaua ki te whakarato i te pūoko whakapā ōrite whānui ki te whiwhi i te whakapakoko kounga teitei. Whakamahia ki te matawai i te thyroid, uma, reo-rahi hononga, me te uaua kiko.
2. Koropuku. 1,9-7,5 MHz auau. Matawai i te mata o te roa iti atu i te pūoko raina. Whakarite he ōrite whakapā raru ki te kiri. E horo'a te pikitia kuiti, ahua mio'i i te rahi, engari hōhonu tirohanga ki te 25 cm. Kei te whakamahia te reira mo te whakamātautau o te kōhao puku, me te retroperitoneal, pūnaha urogenital, hononga nui (huha, hei tauira).
3. Rängai. whakamahi te reira i te auau o 1.5-5 MHz. Image nui tūturu. homai te reira i te kaha ki te matawai i i te hohonu nui. Nuinga o ngā wā e whakamahia ana mō te echocardiography.

momo rerekē o pūoko whakamahia ki te titiro i te puku whekau, ngakau, thyroid, uma, tuaiwi me hononga. I tua atu, i reira he microsensors mō endoscopy me te unuhanga ngira.

whakamātautau o te wahine hapu

whakaaro te kōwhiringa pai mo te whakamātautau tonu o te wahine hapu ki te waiho i te sonography rorohiko. Taua taputapu taea te whakaaro tino tupato ki nga whekau kāwanatanga o te kukune, mai te rahi chetyrehsantimetrovogo. He haumaru rawa te rangahau. e tauturu te reira ki te wha o wiki o te hapūtanga whakarongo ki te mokowhiti, ki te tautuhi me te whakakore i te riri o te materoto, gestational whakamārama, te tāutu i takaroa whanaketanga, me te tahi atu ine.

Patency o nga korere kākano

Ko te hiahia ki te aromatawai i patency o nga korere kākano puta i roto i nga wahine, e kore e taea e te tangata e hapu mo te wā roa. Sonography o nga korere kākano - he tikanga o te aromātai i te take e kore hoki e taea te whakatau i te hua manu i te parāoa.

Tuatahi, tirohia te tākuta te āhua o te kōhao uterine, kia tino te wahine e kore he hapu, me te he kahore adhesions, polyps me pae. I tua atu, e whakahaeretia ana te awa waha te saline me arotakea te whakamahi i sonography korere kākano. Ki te mea ko watea nga putorino, ringihia te wai kei te i ngā taha e rua o nga whekau i roto i te puku. Ki te kore te mea tukua te wai, a ka whakakiia ana he wāhanga o te pūkano me kōpū, he reira putorino nanakia. tika e taea e Ultrasound te whakatau i te wāhi o te poraka.

Ki te matau te manawanui te tikanga o te wā "ultrasound", he aha te mea te reira, a kua whakaritea he aha koutou tākuta whakamātautau, e kore e ite i te reira wehi, rite ki te whakarite i nga whakaritenga e tika ana o te tākuta, me te tika e pā ana ki te tukanga. Mai i tenei, tei reira ki runga ki nga mea maha. Ka rite ki maha, hei utu o te whakamātautau me te maimoatanga o te tūroro wehi tahuri ki Herekiu me "tohunga", ngaro wa utu nui.
