Mai i tōna tīmatanga, he mea nui te mahi a ngā ngongo hihi-X hauora i roto i te hurihanga whakaahua tātaritanga. He wāhanga nui ēnei ngongo o ngā mīhini hihi-X e taea ai e ngā tākuta te kite i roto i ngā tūroro me te tātaritanga i ngā momo mate hauora. Mā te mārama ki ngā mahi o roto o ngā ngongo hihi-X hauora ka taea te whakarei ake i tō tātou māramatanga ki ngā whanaketanga hangarau e pana ana i te whakaahua tātaritanga ki ngā taumata hou.
Ko te uho o tētahingongo hihi-X hauoraE rua ngā wāhanga matua o tēnei rauemi: he katote me he anote, e mahi tahi ana hei whakaputa i tētahi hihi hihi-X. Ko te katote te pūtake o ngā irahiko, ko te anote te pūtake mō ēnei irahiko. Ina tukuna te pūngao hiko ki te ngongo, ka tukuna e te katote he rerenga irahiko, ka arotahihia, ka whakaterea ki te anote.
Ko te katote he miro wera, he mea hanga i te tungsten, e tuku ana i ngā irahiko mā te tukanga e kiia nei ko te tukunga thermionic. Ka whakamahanahia te miro e te iahiko kaha, ka puta ngā irahiko mai i tōna mata, ka hanga he kapua o ngā matūriki utu kino. Kātahi ka hangaia he kapu arotahi i hangaia ki te nikara hei kapua o ngā irahiko hei hihi whaiti.
I tērā taha o te ngongo, ka mahi te anode hei ūnga mō ngā irahiko e tukuna ana e te katote. Ko te anode he mea hanga i te tungsten, i tētahi atu rauemi tau ngota rānei teitei nā te mea he teitei te ira rewa me tōna kaha ki te tu atu i te wera nui e puta mai ana i te pupuhi irahiko. Ina tukinga ngā irahiko tere-teitei ki te anode, ka tere te puhoi, ka tukuna te pūngao i roto i te ahua o ngā photon hihi-X.
Ko tētahi o ngā mea tino nui i roto i te hoahoa o ngā ngongo hihi-X ko te kaha ki te tohatoha i te nui o te wera e puta ana i te wā e whakamahia ana. Hei whakatutuki i tēnei, kua whakauruhia te ngongo hihi-X ki tētahi pūnaha whakamatao matatau hei ārai i te wera nui me te pirau o te anode. Ko te tikanga o ēnei pūnaha whakamatao ko te rere o te hinu, te wai rānei huri noa i te anode, kia mimiti ai, kia marara ai hoki te wera.
Ko te hihi X-ray e tukuna ana e te ngongo ka hangaia anōtia, ka arahina hoki e ngā collimator, e whakahaere ana i te rahi, te kaha me te āhua o te mara hihi X-ray. Mā tēnei ka taea e ngā tākuta te arotahi tika i ngā hihi X-ray ki ngā wāhi e hiahiatia ana, ka whakawhāiti i te pānga o te irahiko koretake ki ngā tūroro.
Nā te whanaketanga o ngā ngongo hihi-X hauora i huri te whakaahua tātaritanga mā te hoatu ki ngā tākuta he taputapu kore-whakaeke hei tiro i ngā hanganga o roto o te tinana. Kua kitea he mea nui ngā hihi-X ki te kimi i ngā whati wheua, te tautuhi i ngā pukupuku me te tirotiro i ngā mate maha. Hei tāpiri, kua whanake te hangarau hihi-X ki te whakauru i te tomography rorohiko (CT), te fluoroscopy, me te mammography, ā, kua whānui ake ōna āheinga tātaritanga.
Ahakoa ngā painga maha o ngā ngongo hihi-X, me whakaae ngā tūponotanga mōrearea e pā ana ki te pānga o te hihi-X. Kua whakangungua ngā tohunga hauora ki te whakataurite i ngā painga o te whakaahua hihi-X me ngā kino pea o te taikaha o te hihi. Mā ngā tikanga haumaru pakari me te aroturuki i te horopeta hihi ka whakarite kia whiwhi ngā tūroro i ngā mōhiohio tātaritanga e tika ana, me te whakaiti i te pānga o te hihi.
Hei whakarāpopototanga,ngā ngongo hihi-X hauorakua hurihia te whakaahua tātaritanga mā te tuku i ngā tākuta ki te tūhura i ngā mahi o roto o te tinana tangata me te kore he tikanga whakaeke. Ko te hoahoa uaua o te ngongo hihi-X me tōna katote, anote me te pūnaha whakamatao ka puta he whakaahua hihi-X kounga teitei hei āwhina i te tātaritanga tika. I te haere tonu o te whanaketanga o te hangarau, ka taea e tātou te tumanako kia whakapai ake i te whakaahua hihi-X hei painga mō ngā tūroro me ngā tohunga hauora.
