ʻO ka ʻike ʻana i nā mea haumia ʻo ia ka hoʻohana mua ʻana o nā ʻōnaehana nānā X-ray i ka meaʻai a me ka hana lāʻau lapaʻau, a he mea nui ia e hōʻoia i ka wehe ʻia ʻana o nā mea poke a pau me ka nānā ʻole i ke ʻano o ka noi a me ke ʻano o ka pahu e hōʻoia ai i ka palekana o ka meaʻai.
ʻO nā ʻōnaehana X-ray o kēia manawa he mea kūikawā, kūpono a holomua, a hoʻohana ʻia i nā ʻano ʻoihana ākea no ka nānā ʻana, me nā diagnostics lapaʻau, nā meaʻai a me nā huahana pharmaceutical inspection, construction (structural, mining and engineering), a me ka palekana. Ma ke kahua palekana, hoʻohana ʻia lākou e "ʻike" i loko o nā ukana a i ʻole nā ​​pūʻolo. Ke hilinaʻi pū nei nā mea hana meaʻai a me nā lāʻau lapaʻau i nā ʻōnaehana X-ray e ʻike a wehe i nā huahana i hoʻohaumia ʻia mai nā laina hana e pale aku i nā mea kūʻai aku, e hōʻemi i ka hopena o ka hoʻomanaʻo ʻana o nā huahana a mālama i kā lākou mau hōʻailona.
Akā, pehea e ʻike ai nā ʻōnaehana X-ray i nā mea haumia? Hōʻike kēia ʻatikala i ke ʻano o nā kukui X a pehea e hana ai nā ʻōnaehana nānā X-ray.
1. He aha ka X-ray?
ʻO nā kukuna X kekahi o nā radiation kūlohelohe maoli a he ʻano ʻike ʻole ʻia o ka radiation electromagnetic, e like me nā hawewe lekiō. ʻO nā ʻano like ʻole o ka radiation electromagnetic he hoʻokahi continuum i ka spectrum electromagnetic, i hoʻonohonoho ʻia e like me ke alapine a me ka lōʻihi o ka nalu. Hoʻomaka ia me nā hawewe lekiō (lōʻihi hawewe lōʻihi) a pau me nā kukuna gamma (lōʻihi hawewe pōkole). ʻO ka lōʻihi hawewe pōkole o nā kukui X e hiki ai iā lākou ke komo i nā mea opaque i ka mālamalama ʻike ʻia, akā ʻaʻole pono lākou e komo i nā mea āpau. ʻO ka hoʻouna ʻana o kahi mea e pili pono ana i kona mānoanoa - ʻo ka ʻoi aku ka nui o ia mea, ʻoi aku ka liʻiliʻi o nā kukui X i hoʻouna ʻia. Hōʻike ʻia nā mea haumia huna, e like me ke aniani, ka iwi calcified a me ka metala, no ka mea, ʻoi aku ka nui o nā kukui X ma mua o ka huahana a puni.
2. X-ray Inspection Loin Nā Manaʻo Nui
I ka pōkole, hoʻohana ka ʻōnaehana X-ray i kahi mea hana X-ray e hoʻolālā i kahi kukui X-ray haʻahaʻa haʻahaʻa ma luna o kahi mea ʻike a ʻike paha. Ke hele nei ka huahana a i ʻole ka pūʻolo ma ke kukui X-ray a hiki i ka mea ʻike. ʻO ka nui o ka ikehu X-ray i hoʻopaʻa ʻia e ka huahana e pili ana i ka mānoanoa, density a me ka helu atomika o ka huahana. Ke hele ka huahana ma ka X-ray beam, ʻo ke koena o ka ikehu e hiki i ka mea ʻike. ʻO ke ana ʻana i ka ʻokoʻa o ka absorption ma waena o ka huahana a me ka mea haumia ke kumu o ka ʻike kino haole ma ka nānā ʻana i ka X-ray.
