Ngā mātāpono o te whakaahua oro-ataata

Ko te Whakaahua Whakaahua-ā-Ao (PAI) he tikanga whakaahua hauora e whakakotahi ana i ngāngā tirohangame te oro hei whakaputa tohu ultrasonic mā te whakamahi i te taunekeneke omāramame te kiko hei tiki whakaahua kiko tino taumira. He whānuitia te whakamahinga i roto i ngā mara hauora, inā koa i roto i te kimi pukupuku, te whakaahua toto, te whakaahua kiri me ētahi atu mara.

Mātāpono:
1. Te mimiti mārama me te whakawhanui wera: – Ka whakamahia e te whakaahua whakaahua-oro te pānga wera i puta mai i te mimiti mārama. Ka mimitihia e ngā ngota tae i roto i te kiko (hei tauira, te hemoglobin, te melanin) ngā photon (te nuinga o te wā he mārama tata-whero), ka hurihia hei pūngao wera, ka piki ake te pāmahana o te rohe.
2. Ka hua ake te whaanuitanga wera i te orooro: – Ka hua ake te whaanuitanga wera iti o te kiko i te pikinga o te pāmahana, ka puta ai ngā ngaru pēhanga (arā, te orooro).
3. Te kimi i te orooro: – Ka horapa ngā ngaru orooro i hangaia i roto i te kiko, ā, ka riro mai ēnei tohu i ngā pūoko orooro (pērā i ngā pūoko orooro).
4. Te hanga anō i te ahua: ka tatauhia, ka tukatukahia te tohu ultrasonic kua kohia hei hanga anō i te ahua hanganga me te mahi o te kiko, ka taea te whakarato i ngā āhuatanga mimiti whatu o te kiko. Ngā painga o te whakaahua photoacoustic: Te rerekētanga teitei: Ka whakawhirinaki te whakaahua photoacoustic ki ngā āhuatanga mimiti mārama o ngā kiko, ā, he rerekē ngā kaha o ngā kiko rerekē (pēnei i te toto, te ngako, te uaua, me ētahi atu) ki te mimiti mārama, nō reira ka taea te whakarato i ngā ahua rerekētanga teitei. Te taumira teitei: Mā te whakamahi i te taumira ā-wāhi teitei o te ultrasound, ka taea e te whakaahua photoacoustic te whakatutuki i te tika o te whakaahua mirimita, tae noa ki raro iho i te mirimita. Kore-whakaeke: Ko te whakaahua photoacoustic ehara i te mea whakaeke, kāore te mārama me te oro e kino ki te kiko, he tino pai mō te tātaritanga hauora tangata. Te kaha o te whakaahua hohonu: Ki te whakatauritea ki te whakaahua whatu tuku iho, ka taea e te whakaahua photoacoustic te uru ki roto i ētahi henimita ki raro i te kiri, he pai mō te whakaahua kiko hohonu.

Taupānga:
1. Whakaahua toto: – Ka taea e te whakaahua photoacoustic te kite i ngā āhuatanga mimiti mārama o te hemoglobin i roto i te toto, kia taea ai te whakaatu tika i te hanganga me te āhua o te hāora o ngā toto hei aroturuki i te tohanga moroiti me te aromatawai i ngā mate.
2. Te kimi i te puku: – He tino nui te angiogenesis i roto i ngā kiko puku, ā, ka taea e te whakaahua photoacoustic te āwhina i te kimi wawe i ngā puku mā te kimi i ngā rerekētanga o te hanganga toto.
3. Whakaahua mahi: – Ka taea e te whakaahua whakaahua-oro te aromatawai i te tuku hāora ki ngā kiko mā te kite i te kukū o te hāora me te deoxyhemoglobin i roto i ngā kiko, he mea tino nui tēnei mō te aroturuki mahi o ngā mate pēnei i te mate pukupuku me te mate manawa.
4. Whakaahua kiri: – Nā te mea he tino tairongo te whakaahua photoacoustic ki ngā kiko o waho, he mea pai mō te kimi wawe i te mate pukupuku kiri me te tātari i ngā āhuatanga rerekē o te kiri.
5. Whakaahua roro: Ka taea e te whakaahua orooro te tiki i ngā mōhiohio e pā ana ki te rere o te toto roro i roto i tētahi huarahi kore-whakaekenga hei ako i ngā mate roro pēnei i te whiu me te mate haurangi.

Ngā wero me ngā huarahi whanaketanga o te whakaahua oro-ataata:
Pūtake māramakōwhiringa: He rerekē te urunga o te mārama ki ngā roangaru rerekē, he wero te whiriwhiri i te taurite o te roangaru tika me te hohonu o te urunga. Tukatuka tohu: Ko te whiwhi me te tukatuka i ngā tohu ultrasonic me whai rauropi tere me te tika, ā, he mea nui anō hoki te whakawhanake i te hangarau hanga whakaahua. Whakaahua maha-ara: Ka taea te whakakotahi i te whakaahua photoacoustic me ētahi atu momo whakaahua (pēnei i te MRI, CT, te whakaahua ultrasound) hei whakarato i ngā mōhiohio hauora whānui ake.

He hangarau whakaahua koiora hou, maha-mahi hoki te whakaahua whakaahua ā-pūoro, he āhuatanga o te rerekētanga teitei, te taumira teitei, me te kore e pokanoa. Nā te whanaketanga o te hangarau, he whānui ngā tono o te whakaahua whakaahua ā-pūoro ki te tātaritanga hauora, te rangahau koiora taketake, te whakawhanaketanga rongoā me ētahi atu mara.
