I teie mahana, kua rongo tata katoa o tomography rorohiko, e tika ana ki tona rongonui. Otira kua whakaritea reira te hunga ki nei, he mea nui ki te mohio i roto i te taipitopito te mea he CT me te parau tumu o tona mahi.

Overview

tomography computed (CT) karapa - he ako papanga hou o te tinana tangata. Kei te hāngai te reira i runga i ruri rorohiko, me te tukatuka i te rerekētanga i roto i te attenuation o papanga X-radiation, rerekē i roto i to ratou kiato. tātarihia Mā te computed Tomography tinana kite i koki rerekē, na ko reira taea ki te whiwhi i te whakapakoko i roto i nga haurangi katoa me te puka e toru-ahu.

whakamahi ki te kawe i roto i CT te X-ray CT matawai motuhake. Kei roto te reira i te tepu turanga, tomo te manawanui ki te whakatuwheratanga o te kōwae matawai, he radiation me ai pūoko X-ray ngongo.

X-hihi haere i roto i te ako o te radiation tinana tangata riro kahakore rite haere te reira i roto i te kiko. Tītaka i te koki o te 360 nekehanga a tawhio noa te manawanui, X-ray kaituku matawai te wahi o tona tinana i koki rerekē. I tenei wa nga tikanga pūoko i roto i te tahi atu taha o te manawanui whai wāhi i roto i te faafariuraa o te iraruke pūngao ponana hiko. Na ka haere ratou i roto i te tukatuka rorohiko, ka taea te kite i te hua o nei i runga i te aroturuki. Ko te whiwhi rangahau whakapakoko, me te tātari i te radiologist, ka tuhi ki te reo tuhi , me te ka tā ratou i runga i te rīpene. kore e te tukanga rangahau katoa neke atu i te 10 meneti, engari ki runga ki te matawai rānei ka hiahiatia te rohe pāngia motuhake te me ki runga ki te hawhe haora.
