X-ray computed tomography (CT) yakachinja mafungiro ekurapa, ichipa mifananidzo yakadzama yemuviri wemunhu. Chinhu chikuru pakushanda kwemaX-ray CT systems ichubhu yeX-ray, iyo inogadzira maX-ray anodiwa pamifananidzo. Kufambira mberi kwetekinoroji munguva pfupi yapfuura kwakaunza maVFDD anochinja-chinja muX-ray CT systems, zvichivandudza kunaka kwemifananidzo uye kugona kuongorora. Chinyorwa chino chinoongorora mabhenefiti eVFDD muX-ray CT systems uye kuti anoshanda sei nemaX-ray tubes kuti awedzere mhedzisiro yemurwere.
Kunzwisisa daro rekuona zvinoshanduka-shanduka
Chinoongorora zvinhu zvakasiyana-siyana chinoreva kugona kweX-ray CT system kugadzirisa daro riri pakati pechubhu yeX-ray nechinoongorora zvinhu. Masisitimu eCT echinyakare anowanzo shandisa chinhu chakagadziriswa, icho chinoganhurira kushanduka-shanduka kwemifananidzo uye kunaka kwayo. Nekutsigira chiono chakasiyana-siyana, masisitimu eCT emazuva ano anogona kugadzirisa maitiro ekutora mifananidzo zvichienderana nezvinodiwa zve scan yega yega.
Wedzera kunaka kwemufananidzo
Chimwe chezvakanakira zvikuru zveVFDD muma X-ray CT systems ndechekuvandudza zvakanyanya kunaka kwemufananidzo. Nekugadzirisa kureba kwefocal, system inogona kuwedzera kugona kwenzvimbo uye kusiyana, zvichikonzera mifananidzo yakajeka uye yakadzama. Izvi zvinobatsira zvikuru munzvimbo dzakaoma dzemuviri, uko mifananidzo chaiyo yakakosha kuti kuongororwa kwakarurama. X-ray chubhu inoita basa rakakosha mukuita uku, sezvo ichigona kuenzaniswa zvichienderana nehurefu hwakagadziridzwa kuti ipe mwero wemwaranzi wakakodzera, ichiva nechokwadi chekuti mhando yemufananidzo inochengetwa pasina kukanganisa kuchengetedzeka kwemurwere.
Kubudirira kwemushonga kwakavandudzwa
Imwe mukana wekuva neruzivo rwekuyera daro revariable focus detector ndeyekuvandudzika kwekushanda zvakanaka kwedose. Munzira dzechinyakare dze fixed-focus, dose yemwaranzi inowanzo fanana zvisinei nenzvimbo yekutora mifananidzo. Izvi zvinogona kukonzera kuratidzwa zvisina kufanira mune dzimwe nzvimbo uye kusaonekwa zvakakwana mune dzimwe. NeVFDD, chubhu yeX-ray inogona kugadzirisa kubuda kwemwaranzi zvichienderana nedaro kubva kune detector, zvichiita kuti kuendeswa kwedose kwakanyatsojeka. Izvi hazvingoderedzi chete kuratidzwa kwemwaranzi nemurwere asiwo zvinovandudza kuchengetedzeka kwese kwekutora mifananidzo.
Maitiro ekufungidzira anochinjika zvakanyanya
Kuunzwa kweVFDD kunoita kuti pave nekuchinjika kukuru muzvirongwa zvemifananidzo. Vanachiremba vanogona kugadzirisa urefu hwefocal zvichienderana nezvinodiwa nemurwere nenzvimbo yaanofarira. Semuenzaniso, kureba kwenguva refu kunogona kubatsira zvikuru pakutora mifananidzo yezvikamu zvikuru zvemuviri, nepo kureba kwenguva pfupi kunogona kukodzera zvivako zvidiki, zvakaoma kunzwisisa. Kuchinjika uku kunoita kuti maX-ray CT systems agone kuchinjika kune akasiyana mamiriro ekurapa, zvichiita kuti ave chishandiso chinoshanda pakutora mifananidzo.
Kuvandudzwa kwe3D kwakavandudzwa
Zvishandiso zvinoongorora zvinhu zvakasiyana-siyana zvinobatsirawo mukuvandudza kugona kwekuvakazve zvinhu zvine mativi matatu (3D). Nekutora mifananidzo padaro dzakasiyana-siyana, sisitimu iyi inogona kugadzira mamodheru e3D akanyatsojeka ezvimiro zvemuviri. Izvi zvinobatsira zvikuru mukuronga kuvhiya uye kuongororwa kwekurapa, uko mifananidzo ye3D chaiyo yakakosha kuti pave nemigumisiro inobudirira. Kuvimbika kwekugadzirwazve uku kunowedzerwa nekukwanisa kwechubhu yeX-ray kupa mifananidzo yakafanana, yepamusoro-soro padaro dzakasiyana.
mukupedzisa
Muchidimbu, kubatanidzwa kwezviyereso zvekutarisa kure (VFDDs) muX-ray CT systems kunomiririra kufambira mberi kukuru muhunyanzvi hwemifananidzo yekurapa. Nekuvandudza hukama huripo pakati pechubhu yeX-ray ne detector, VFDDs inowedzera kunaka kwemufananidzo, inovandudza kushanda zvakanaka kwedosi, uye inopa kuchinjika kukuru muzvirongwa zvemifananidzo. Sezvo ndima ye radiology ichiramba ichifambira mberi, izvi zvitsva pasina mubvunzo zvichatungamira kune kugona kwakasimba kwekuongorora uye kuvandudzwa kwekutarisira kwevarwere. Remangwana reX-ray CT systems rakajeka, uye VFDDs dzichagadzira nzira yemhinduro dzemifananidzo dzakanyatsojeka uye dzinoshanda.
