Me ka holomua o ka ʻepekema a me ka ʻenehana a me ka hoʻomohala ʻana i ka ʻenehana lapaʻau, ua hoʻonui nui ʻia ka manawa o ka poʻe i ʻike ʻia i nā kukui X ke hele lākou i ka haukapila.Ua ʻike nā kānaka a pau e hiki i nā pahu X-ray, CT, color ultrasound a me nā mīkini X-ray ke hoʻopuka i nā kukui X e komo i ke kino o ke kanaka e nānā i ka maʻi.Ua ʻike nō hoʻi lākou e hoʻopuka ana nā kukuna X, akā ʻehia ka poʻe i maopopo maoli i nā mīkini X-ray.Pehea e pili ana i nā kukuna i hoʻokuʻu ʻia?
ʻO ka mea mua, pehea ka X-ray i kahiMīkini X-rayhanaia?ʻO nā kūlana i koi ʻia no ka hana ʻana i nā kukui X i hoʻohana ʻia i ka lāʻau lapaʻau penei: 1. X-ray tube: he paipu aniani ʻeleʻele ʻelua mau electrodes, cathode a me anode;2. ʻO ka pā tungsten: hiki ke hoʻohana ʻia ka tungsten metala me ka helu atomic kiʻekiʻe e hana i nā paipu X-ray ʻO ka anode ka pahuhopu no ka loaʻa ʻana o ka pōkā electron;3. E neʻe ana nā electrons i ka wikiwiki kiʻekiʻe: e hoʻopili i ka uila kiʻekiʻe ma nā ʻaoʻao ʻelua o ka paipu X-ray i mea e neʻe ai nā electrons i ka wikiwiki kiʻekiʻe.Hoʻonui nā mea hoʻololi kūikawā i ka volta ola i ka volta kiʻekiʻe i koi ʻia.Ma hope o ka paʻi ʻana o ka pā tungsten e nā electrons e neʻe ana i ka wikiwiki kiʻekiʻe, hiki ke hoʻokaʻawale ʻia nā atom o tungsten i nā electrons e hana i nā kukui X.
ʻO ka lua, he aha ke ʻano o kēia X-ray, a no ke aha e hiki ai ke hoʻohana ʻia e nānā i ke kūlana ma hope o ke komo ʻana i ke kino kanaka?Loaʻa kēia ma muli o nā waiwai o nā kukui X, nona nā waiwai nui ʻekolu:
1. Ke komo ʻana: ʻO ke komo ʻana e pili ana i ka hiki o nā kukui X ke hele i loko o kahi mea me ka ʻole o ka komo ʻana.Hiki i nā kukui X ke komo i nā mea i hiki ʻole i ke kukui ʻike maka.He lōʻihi ka nalu ʻike maka, a he liʻiliʻi ka ikehu o nā photon.Ke kuʻi ʻo ia i kahi mea, ʻike ʻia kekahi hapa o ia mea, ʻo ka hapa nui o ia mea e komo i ka mea, ʻaʻole hiki ke hele i loko o ka mea;ʻOiai ʻaʻole nā kukui X, no ka lōʻihi o ka nalu pōkole, ka ikehu Ke hoʻomālamalama ʻo ia i ka mea, hoʻopili wale ʻia kahi hapa e ka mea, a ʻo ka hapa nui o ia mea e hoʻouna ʻia ma o ka ʻāpana atomic, e hōʻike ana i kahi hiki ke komo ikaika.ʻO ka hiki o nā kukui X ke komo i ka mea pili i ka ikehu o nā kiʻi X-ray.ʻOi aku ka pōkole o ka nalu o nā kukui X, ʻoi aku ka nui o ka ikehu o nā photon a ʻoi aku ka ikaika o ka mana komo.ʻO ka mana komo o nā kukui X e pili pū ana me ka nui o ka mea.ʻO ka mea ʻoi aku ka ʻoi aku ka nui o nā X-ray a hoʻouna liʻiliʻi;ʻoi aku ka liʻiliʻi o ka mea ʻoi aku ka paʻa a hoʻouna hou aku.Ma ka hoʻohana ʻana i kēia waiwai o ka absorption ʻokoʻa, hiki ke ʻike ʻia nā ʻiʻo palupalu e like me nā iwi, nā ʻiʻo, a me nā momona me nā ʻano like ʻole.ʻO kēia ke kumu kino o X-ray fluoroscopy a me ke kiʻi.
2. Ionization: Ke hoʻomālamalama ʻia kahi mea e nā kukui X, hoʻoneʻe ʻia nā electron extranuclear mai ka orbit atomika.Kapa ʻia kēia hopena i ka ionization.Ma ke kaʻina hana o ka hopena photoelectric a me ka hoʻopuehu ʻana, ʻo ke kaʻina hana i hoʻokaʻawale ʻia ai nā photoelectrons a me nā electrons recoil mai kā lākou mau mana i kapa ʻia ʻo ka ionization mua.Kūleʻa kēia mau photoelectrons a i ʻole recoil electrons me nā ʻātoma ʻē aʻe i ka wā e hele ana, no laila ua kapa ʻia nā electrons mai nā ʻātoma paʻa i ka ionization lua.i loko o nā mea paʻa a me nā wai.E hui hou nā ionized maikaʻi a maikaʻi ʻole a ʻaʻole maʻalahi e hōʻiliʻili.Eia naʻe, maʻalahi ka hōʻiliʻili ʻana i ka uku ionized i loko o ke kinoea, a hiki ke hoʻohana ʻia ka nui o ka uku ionized e hoʻoholo ai i ka nui o ka hoʻolaha ʻana i ka X-ray: Hana ʻia nā mea ana X-ray ma muli o kēia kumu.Ma muli o ka ionization, hiki i nā kinoea ke alakaʻi i ka uila;hiki i kekahi mau mea ke komo i nā hopena kemika;hiki ke hoʻoulu ʻia nā hopena olaola like ʻole i loko o ke kino.ʻO ka Ionization ke kumu o ka pōʻino X-ray a me ka mālama ʻana.
3. Fluorescence: Ma muli o ka lōʻihi hawewe pōkole o nā kukui X, ʻaʻole ʻike ʻia.Eia nō naʻe, i ka wā e hoʻomālamalama ʻia ai i kekahi mau pūhui e like me ka phosphorus, platinum cyanide, zinc cadmium sulfide, calcium tungstate, a me nā mea ʻē aʻe, aia nā atoms i kahi kūlana hauʻoli ma muli o ka ionization a i ʻole excitation, a hoʻi nā atoms i ka ʻāina i ke kaʻina hana. , ma muli o ka hoʻololi pae ikehu o nā electrons valence.Hoʻopuka ia i ke kukui ʻike ʻia a i ʻole ultraviolet, ʻo ia ka fluorescence.ʻO ka hopena o nā kukui X e hoʻoulu ai i nā mea i kapa ʻia ʻo fluorescence.ʻO ka ikaika o ka fluorescence e like me ka nui o nā kukui X.ʻO kēia hopena ke kumu no ka noi ʻana o nā kukui X i ka fluoroscopy.Ma ka hana diagnostic X-ray, hiki ke hoʻohana ʻia kēia ʻano fluorescence e hana i ka pale fluorescent, ka hoʻoikaika ʻana i ka pale, ka pale hoʻokomo i ka intensifier kiʻi a pēlā aku.Hoʻohana ʻia ka pale fluorescent e nānā i nā kiʻi o nā kukui X e hele ana i loko o ke kino kanaka i ka wā fluoroscopy, a hoʻohana ʻia ka pale hoʻoikaika e hoʻonui i ka naʻau o ke kiʻiʻoniʻoni i ka wā kiʻi.ʻO ka mea i luna nei he hoʻolauna maʻamau i nā kukui X.
