Musanganiswa wegranite weComputed Tomography (CT) idhizaini yakasarudzika inoshandiswa mune zvehutano kuita scan dzakarurama uye dzakanyatsojeka dzemuviri wemunhu. CT scanning ndeimwe yekufambira mberi kukuru kwetekinoroji mune zvekurapa, sezvo ichigonesa vanachiremba kuona zvirwere zvakasiyana-siyana nemazvo. Midziyo yemifananidzo yeCT scans inoshandisa tekinoroji yeX-ray kugadzira mufananidzo we3D wemuviri, izvo zvinobvumira vanachiremba kuwana nekuona kukura kusingawanzoitiki, kukuvara, uye zvirwere zvisina kupindira zvakanyanya.
Musanganiswa wegranite weCT une zvikamu zviviri: granite gantry negranite tabletop. Gantry ine basa rekuisa michina yemifananidzo uye kutenderera murwere panguva yekuskena. Kusiyana neizvi, tabletop inotsigira huremu hwemurwere uye inoita kuti agare akadzikama uye arege kufamba panguva yekuskena. Zvinhu izvi zvakagadzirwa negranite yemhando yepamusoro, yakasimba, ine hunhu hwakanaka hwekudzivirira kukanganisa kunokonzerwa nekusiyana kwezvakatipoteredza, senge shanduko dzetembiricha nehunyoro.
Gantry yegranite yakagadzirwa kuti isanganise zvinhu zvakasiyana zvinodiwa pakuongorora CT, zvakaita sechubhu yeX-ray, detector array, uye collimation system. Chubhu yeX-ray iri mukati megantry, uko inoburitsa maX-ray anopinda mumuviri kuti igadzire mufananidzo we3D. Detector array, iyo iriwo mukati megantry, inotora maX-ray anopfuura nemumuviri uye inoatumira kucomputer system kuti ivandudzwezve. Sisitimu yecollimation inzira inoshandiswa kutetepa mwenje weX-ray kuderedza huwandu hwemwaranzi iyo varwere vanosangana nayo panguva yekuskena.
Tebhureti yegranite chinhu chakakoshawo muCT system. Inopa puratifomu inotsigira huremu hwevarwere panguva yekuskena uye inoita kuti nzvimbo yavo igare yakagadzikana, isina kufamba-famba mukati mese. Tebhureti inewo zvinhu zvinobatsira pakumisa, zvakaita setambo, macushion, uye michina yekumisa kufamba, izvo zvinoita kuti muviri uve panzvimbo yakakodzera yekuskena. Tebhureti inofanira kunge yakatsetseka, yakati sandara, uye isina chero kuchinja kana kukanganisa kudzivirira chero zvinhu zvakagadzirwa mumifananidzo inogadzirwa.
Mukupedzisa, kuunganidza granite yeCT scanning kunoita basa rakakosha mukururama uye kunyatsoita kwemaitiro ekurapa emifananidzo. Kushandiswa kwegranite yepamusoro mumidziyo yekurapa kunowedzera kugadzikana kwemuchina, kugadzikana kwekupisa, uye hunhu hwekuwedzera husina kupisa zvakanyanya hwemidziyo, izvo zvakakosha kuti uwane mhedzisiro yemifananidzo yakanakisa. Nekunzwisisa kuri nani kwemaitiro ekugadzira uye kubatanidzwa kwekufambira mberi kutsva muzvikamu, ramangwana reCT scanning rinotaridzika rakajeka uye risingapindiri zvakanyanya kune varwere.
