He hoahoa motuhake te huihuinga karāhe mō te Tomography Rorohiko (CT) e whakamahia ana i roto i te ao hauora hei mahi i ngā matawai tino tika me te tika o te tinana tangata. Ko te matawai CT tētahi o ngā whanaketanga hangarau tino nui i roto i te ao whakaahua hauora, nā te mea ka taea e ngā tākuta te tātari tika i ngā momo mate hauora. Ka whakamahia e ngā taputapu whakaahua mō ngā matawai CT te hangarau hihi-X hei hanga i tētahi ahua 3D o te tinana, e taea ai e ngā tākuta te kimi me te tautuhi i ngā tipu rerekē, ngā whara, me ngā mate me te iti rawa o te whakaekenga.
Ko te huihuinga karāhe mō te CT he mea hanga ki ngā wāhanga e rua: te tārewa karāhe me te papa tēpu karāhe. Ko te tārewa te kawenga mō te pupuri i ngā taputapu whakaahua me te hurihuri huri noa i te tūroro i te wā e matawaihia ana. He rerekē, ko te papa tēpu te tautoko i te taumaha o te tūroro, ā, ka whakarite kia pumau, kia kore e nekeneke i te wā e matawaihia ana. He mea hanga ēnei wāhanga mai i te karāhe kounga teitei, he pakari, he āhuatanga pai hei karo i ngā hapa i puta mai i ngā rerekētanga taiao, pērā i ngā huringa pāmahana me te haumākū.
Kua hangaia te angaanga karāhe hei whakauru i ngā wāhanga rerekē e hiahiatia ana mō te matawai CT, pērā i te ngongo hihi-X, te huinga taputapu kite, me te pūnaha whakakotahi. Kei roto i te angaanga te ngongo hihi-X, ka tukuna ngā hihi-X e uru ana ki te tinana hei hanga i tētahi ahua 3D. Ko te huinga taputapu kite, kei roto hoki i te angaanga, ka hopu i ngā hihi-X e tika ana mā roto i te tinana, ka tukuna atu ki te pūnaha rorohiko hei hanga anō i te ahua. Ko te pūnaha whakakotahi he tikanga e whakamahia ana hei whakawhāiti i te hihi hihi-X hei whakaiti i te nui o te irahiko e pāngia ana e ngā tūroro i te wā o te matawai.
He wāhanga nui anō hoki te papa tēpu karāhe o te pūnaha CT. He tūāpapa tēnei hei tautoko i te taumaha o ngā tūroro i te wā e matawai ana, ā, ka whakarite kia mau tonu te tūnga pumau, kore e nekeneke i te wā katoa o te tukanga. Kei te papa tēpu anō hoki ngā āwhina tūnga motuhake, pērā i ngā whitiki, ngā urunga, me ngā taputapu ārai, e whakarite ana kia tika te tūnga o te tinana mō te matawai. Me maeneene, me papatahi, me te kore he āhua rerekē, he whanoke rānei o te papa tēpu hei ārai i ngā āhuatanga o ngā whakaahua i hangaia.
Hei whakamutunga, he mea nui te huihuinga kōhatu mō te matawai CT ki te tika me te pūmau o te tukanga whakaahua hauora. Mā te whakamahinga o te kōhatu kounga teitei i roto i ngā taputapu hauora ka whakarei ake i te pumau ā-pūkaha, te pumau wera, me ngā āhuatanga whakawhanui wera iti o ngā taputapu, he mea nui ēnei hei whakatutuki i ngā hua whakaahua pai rawa atu. Mā te mārama ake ki ngā āhuatanga hoahoa me te whakaurunga o ngā whanaketanga hou ki roto i ngā wāhanga, ka mārama ake te heke mai o te matawai CT, ā, ka iti ake te whakaekenga mō ngā tūroro.
