Ua hoʻomohala ʻia ka ʻenehana hōʻike kiʻi kani kani kani no ka hapalua haneli ma Kina.Me ka hoʻomau mau ʻana o ka ʻenehana ʻike uila a me ka ʻenehana kiʻi kamepiula, ua hoʻomohala hou ʻia nā lako diagnostic ultrasonic no nā manawa he nui, mai ka hōʻailona analog / ʻeleʻele a keʻokeʻo ultrasound / harmonic contrast / artificial recognition, i ka hōʻailona kikohoʻe / kala ultrasound / elastic imaging / ʻike akamai.Ke hoʻomau nei ka hoʻonui ʻia ʻana o nā hana hou a me nā pae noi, a ke hoʻomau nei nā mea hana diagnostic imaging ultrasonic i nā mea hou a wāwahi, e koi ana i ka ʻoihana olakino e loaʻa i kahi koi nui no ia.
01. Hoʻokaʻawale kumu o nā mea hana diagnostic imaging maʻamau
ʻO nā mea hana diagnostic imaging ultrasonic kahi ʻano o nā lako diagnostic clinical i hoʻomohala ʻia e like me ke kumu o ka ultrasound.Ke hoʻohālikelikeʻia me nā mea lapaʻau nui e like me CT a me MRI, he haʻahaʻa loa kona kumukūʻai nānā, a loaʻa iā ia nā mea maikaʻi o ka non-invasive a me ka manawa maoli.No laila, ʻoi aku ka nui o ka noi lapaʻau.I kēia manawa, hoʻokaʻawale ʻia ka nānā ʻana i ka ultrasound i ke ʻano A-type ultrasound (hoʻokahi-dimensional ultrasound), B-type ultrasound (ʻelua-dimensional ultrasound), ʻekolu-dimensional ultrasound a me ʻehā-dimensional ultrasound.
ʻO ka mea maʻamau i kapa ʻia ʻo B-ultrasound, pili maoli ia i ka ʻeleʻele a me ke keʻokeʻo ʻelua-nui B-ultrasound, ʻo ke kiʻi i hōʻiliʻili ʻia he mokulele ʻeleʻele a keʻokeʻo ʻelua, a ʻo ka ultrasound kala ka hōʻailona koko i hōʻiliʻili ʻia, ma hope o ka hoʻopaʻa ʻana o ka kala kala ma luna. ke kiʻi ʻelua-dimensional i ka superposition manawa maoli, ʻo ia hoʻi, ka hoʻokumu ʻana o ke kala Doppler ultrasound kiʻi koko.
Hoʻokumu ʻia ka ʻike kani ultrasonic ʻekolu-dimensional ma ka kala Doppler ultrasonic diagnostic instrument, ua hoʻonohonoho ʻia ka ʻikepili acquisition device, a ua lawe ʻia ke kūkulu hou ʻana o ke kiʻi ma o nā polokalamu ʻekolu-dimensional, i mea e hana ai i kahi lāʻau lapaʻau e hiki ke hōʻike i ka hana kiʻi kiʻi ʻekolu. Hiki ke hōʻike ʻia nā kino kanaka i ʻoi aku ka stereoscopic a hiki ke ʻike ʻia nā ʻeha.Hoʻokumu ʻia ka ultrasound kala ʻehā ma luna o ka ultrasound kala ʻekolu a me ka vector manawa o ka ʻehā ʻāpana (ka hoʻohālikelike waena).
02. ʻO nā ʻano a me nā noi ʻana o ka ultrasonic probe
I ke kaʻina o ka ultrasonic kiʻi hōʻoia, ultrasonic probe he mea nui o ka ultrasonic diagnostic lako, a he mea ia e hoʻouna a loaʻa i nā hawewe kani ultrasonic i ke kaʻina o ka ultrasonic detection a me ka maʻi.Hoʻopili pololei ka hana o ka probe i nā hiʻohiʻona o ka ultrasonic a me ka ultrasonic detection performance, no laila he mea koʻikoʻi ka probe i ka ʻike kiʻi ultrasonic.
ʻO kekahi mau ʻimi maʻamau i loko o ka ʻimi kani ultrasonic ka mea nui: hoʻokahi aniani convex array probe, phased array probe, linear array probe, volume probe, cavity probe.
1, sʻO ka ʻimi hoʻonaʻauao ʻano aniani ʻeleʻele
ʻO ke kiʻi kani ultrasonic ka huahana o ka hui kokoke o ka probe a me ka ʻōnaehana ʻōnaehana, no laila ma ka mīkini hoʻokahi, pono ka lako polokalamu a me ka lako pono e hoʻokō i nā koi o ka probe kristal hoʻokahi.
Hoʻohana ʻia ka mea hoʻoheheʻe aniani convex hoʻokahi i ka mea hoʻopaʻapaʻa kristal hoʻokahi, convex ka ʻili o ka ʻili, liʻiliʻi ka ʻili pili, ʻano peʻa ke kahua kiʻi, a hoʻohana nui ʻia i ka ʻōpū, obstetrics, māmā a me nā ʻāpana pili ʻē aʻe. nā ʻōpū hohonu.
Nānā maʻi maʻi ʻaʻai
2, ka hoʻopololei ʻana i ka papa kuhikuhi
He pālahalaha ka ʻili o ka ʻimi, he liʻiliʻi ka ʻili pili, he liʻiliʻi ke kahua kokoke, he nui ka māla mamao, a he ʻano peʻahi ke kahua kiʻi, kūpono i ka puʻuwai.
Hoʻokaʻawale ʻia nā ʻimi naʻau i ʻekolu mau ʻāpana e like me ka heluna kanaka noi: nā mākua, nā keiki, a me nā keiki hānau hou: (1) loaʻa i nā pākeke ke kūlana o ka puʻuwai hohonu a me ka wikiwiki o ka hahau ʻana;(2) He pāpaʻu ke kūlana o ka puʻuwai hānau hou a ʻo ka wikiwiki o ke kuʻi ʻana ka wikiwiki loa;(3) Aia ke kūlana o ka puʻuwai o nā keiki ma waena o nā keiki hānau hou a me nā mākua.
Nānā naʻau
3, linear array probe
Palahalaha ka ʻili o ka ʻimi, nui ka ʻili pili, ʻehā ke kahua kiʻi, kiʻekiʻe ka hoʻonā kiʻi, haʻahaʻa haʻahaʻa ke komo ʻana, a kūpono ia no ka nānā ʻana i nā kīʻaha koko, nā ʻāpana liʻiliʻi, musculoskeletal a pēlā aku.
ʻO ka nānā ʻana i ka thyroid
4, volume probe
Ma ke kumu o ke kiʻi ʻelua-dimensional, e hōʻiliʻili mau ka probe volume i ke kūlana hoʻohele spatial, ma o ka algorithm reconstruction computer, i loaʻa ai ke ʻano spatial piha.He kūpono no: alo fetal, iwi kuamoʻo a me nā lālā.
ʻO ka nānā ʻana i ke keiki
5, ka ʻimi ʻana
Loaʻa i ka probe intracavitary nā ʻano o ke alapine kiʻekiʻe a me ka hoʻonā kiʻi kiʻekiʻe, ʻaʻole pono e hoʻopiha i ka ʻōpū.Kokoke ka ʻimi i ka wahi i nānā ʻia, no laila aia ka ʻōpū pelvic ma kahi kokoke i ke kahua o ke kukuna kani, a ʻoi aku ka maopopo o ke kiʻi.
Ka nānā ʻana i nā ʻāpana endovascular
