Ua lilo ka ʻenehana X-ray i mea hana koʻikoʻi i ka ʻoihana palekana. Hāʻawi nā mīkini X-ray palekana i kahi ala ʻaʻole e komohewa ai e ʻike i nā mea huna a i ʻole nā mea weliweli i loko o nā ukana, nā pūʻolo a me nā ipu. Ma ka puʻuwai o kahi mīkini x-ray palekana ʻo ia ka ʻōmole x-ray, ka mea e hana i nā x-ray ikehu kiʻekiʻe i hoʻohana ʻia i ka scan.
Nā ʻōmole kukuna Xhoʻohana ʻia i nā ʻano hana like ʻole i ka radiography, ke kiʻi lapaʻau, ka ʻepekema mea, a me ka loiloi ʻoihana. Eia nō naʻe, i ka ʻoihana palekana, he kuleana koʻikoʻi nā ʻōmole X-ray i ka hōʻoia ʻana i ka palekana o ka lehulehu, ka pale ʻana i ka hana hoʻoweliweli a me ka hoʻoikaika ʻana i ka palekana.
An ʻŌmole kukuna Xhe mea uila ia e hoʻololi i ka ikehu uila i nā kukuna X-ikehu kiʻekiʻe no ke kiʻi ʻana. Aia ka ʻōmole i kahi cathode a me kahi anode i hoʻopaʻa ʻia i loko o kahi keʻena vacuum. Ke hele ke au ma o ka cathode, hoʻokuʻu ia i kahi kahawai o nā electrons, kahi e hoʻolalelale ʻia i ka anode. Kuʻi nā electrons me ka anode, e hana ana i nā kukuna X i kuhikuhi ʻia i ka mea e kālailai ʻia nei.
Hoʻohana nā mīkini X-ray palekana i ʻelua ʻano paipu X-ray: nā paipu metala seramika (MC) a menā paipu anode wili (RA)ʻO ka paipu MC ka mea i hoʻohana pinepine ʻia no ka mea he haʻahaʻa ke kumukūʻai, paʻa a hilinaʻi hoʻi. Hoʻopuka ia i kahi kukuna X-ray paʻa a haʻahaʻa ka ikaika kūpono no ke kiʻi ʻana i nā mea o nā mea haʻahaʻa. Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka ikaika o nā paipu RA ma mua o nā paipu MC a hoʻopuka i kahi kukuna X-ray kiʻekiʻe aʻe. Kūpono no ka nānā ʻana i nā mea me nā mea kiʻekiʻe e like me ka metala.
Hoʻopilikia ʻia ka hana o kahi paipu X-ray i loko o kahi mīkini X-ray palekana e kekahi mau mea, me ke anakahi o ka paipu, ke au o ka paipu, a me ka manawa hōʻike. Hoʻoholo ka anakahi o ka paipu i ka ikehu o nā kukuna X i hana ʻia, ʻoiai ke au o ka paipu e hoʻomalu i ka nui o nā kukuna X i hana ʻia i kēlā me kēia manawa. Hoʻoholo ka manawa hōʻike i ka lōʻihi o nā kukuna X i kuhikuhi ʻia i ka mea e kālailai ʻia ana.
Hoʻohana kekahi mau mīkini X-ray palekana i ka ʻenehana kiʻi X-ray ikehu pālua, kahi e hoʻohana ai i ʻelua mau paipu X-ray me nā pae ikehu like ʻole. Hoʻopuka kekahi paipu i nā kukuna X-ray ikehu haʻahaʻa, aʻo kekahi e hoʻopuka i nā kukuna X-ray ikehu kiʻekiʻe. Hōʻike ke kiʻi hopena i nā kala like ʻole e hōʻike ana i ka nui a me ka helu atomika o kēlā me kēia mea i ke kiʻi i scan ʻia. Hiki i ka ʻenehana i nā mea hana ke hoʻokaʻawale ma waena o nā mea organik a me nā mea inorganic, e hoʻomaikaʻi ana i ka ʻike ʻana i nā mea huna.
I ka hōʻuluʻulu manaʻo, ʻo nā ʻōmole X-ray ke kumu o kahi mīkini X-ray palekana, e kōkua ana i ka ʻike ʻana i nā mea huna, nā mea pahū, a me nā mea weliweli. Hāʻawi lākou i kahi ala wikiwiki, kūpono a ʻaʻole hoʻopilikia e scan i nā ukana, nā pūʻolo a me nā ipu. Me ka ʻole o nā ʻōmole X-ray, he hana paʻakikī a hoʻopau manawa nā nānā palekana, e hoʻolilo ana i ka mālama ʻana i ka palekana o ka lehulehu a me ka pale ʻana i ka hana hoʻoweliweli. No laila, ʻo ka hoʻomohala ʻana i ka ʻenehana ʻōmole X-ray e mau ana ke koʻikoʻi no ka wā e hiki mai ana o nā mīkini X-ray palekana.
