Sawir-qaadayaasha la soo saaray (CT) waa qalab sawir-baadhiseed oo horumarsan oo bixiya sawirro tafatiran oo qaybaha gudaha ah ee jidhka. Isticmaalka raajada iyo tignoolajiyada kombiyuutarka, mashiinadani waxay abuuraan sawirro lakab ah ama "jeex" kuwaas oo la isugu geyn karo matalaad 3D ah. Habka CT-gu wuxuu u shaqeeyaa isagoo ka hagaya raajada raajada ee jirka iyadoo laga eegayo dhinacyo badan. Laydhkan ayaa markaa lagu ogaanayaa dareemayaasha dhinaca ka soo horjeeda, xogtana waxaa lagu farsameeyaa kombuyuutar si ay u abuuraan sawirro heer sare ah oo lafaha, unugyada jilicsan, iyo xididdada dhiigga. Sawirka CT-ga ayaa muhiim u ah ogaanshaha xaalado caafimaad oo kala duwan, laga bilaabo dhaawacyo ilaa kansar, sababtoo ah awoodda ay u leedahay inay bixiso muuqaalo cad oo faahfaahsan ee anatomy gudaha ah.
Sawir-qaadayaasha CT-du waxay ku shaqeeyaan iyagoo bukaanka ku seexanaya miis matoorka leh oo u wareegaya qalab wareeg ah oo weyn. Marka tuubada raajada ay ku wareegeyso bukaanka, baarayaashu waxay qabtaan raajooyinka jirka dhex mara, kuwaas oo loo beddelo sawirro by algorithms kombuyuutar. Qalliinku waa mid degdeg ah oo aan waxba tarayn, iyadoo inta badan baaritaannada lagu dhammeeyo daqiiqado gudahood. Horumarka muhiimka ah ee tignoolajiyada CT-ga, sida xawaaraha sawiridda degdega ah iyo hoos u dhigista soo-gaadhista shucaaca, waxay sii wadaan hagaajinta badbaadada bukaanka iyo waxtarka ogaanshaha. Iyada oo la kaashanayo iskaanka CT-ga casriga ah, dhakhaatiirtu waxay samayn karaan angiography, colonoscopy-ga, iyo sawirka wadnaha, iyo hababka kale.
Noocyada ugu horreeya ee suuqa CT scanner waxaa ka mid ah GE Healthcare, Siemens Healthineers, Philips Healthcare, iyo Canon Systems Medical Systems. Mid kasta oo ka mid ah noocyadan ayaa bixiya noocyo kala duwan oo loogu talagalay in lagu daboolo baahiyaha caafimaad ee kala duwan, laga bilaabo sawir-qaadista xallinta sare ilaa si degdeg ah, sawirka jirka oo dhan. Taxanaha GE's Revolution CT, Siemens 'SOMATOM series, Philips' Inciive CT, iyo Canon's Aquilion series waa xulashooyin si wanaagsan loo tixgaliyo oo bixiya tignoolajiyada casriga ah. Mashiinadan waxaa si toos ah looga iibsan karaa soosaarayaasha ama iibiyeyaasha qalabka caafimaadka ee idman, iyadoo qiimahoodu aad u kala duwan yahay iyadoo ku xiran nooca, awooda sawirida, iyo gobolka.
CT Injectors: CT Single InjectoriyoCT Dual Head Injector
Cirbadaha CT-ga, oo ay ku jiraan hal-Head iyo xulashooyinka laba-madax, ayaa door muhiim ah ka ciyaara maamulida wakiilada isbarbardhigga inta lagu jiro CT scans. Cirbadahani waxay u oggolaanayaan in si sax ah loo xakameeyo duritaanka warbaahinta isbarbardhigga, taas oo kor u qaadeysa caddaynta xididdada dhiigga, xubnaha, iyo qaababka kale ee sawirada natiijada. Injectors Single-Head waxaa loo isticmaalaa maamulka isbarbardhiga tooska ah, halka dual-Head injectors ay si isku xigta ama isku mar u keeni karaan laba wakiil ama xalal kala duwan, hagaajinta dabacsanaanta bixinta isbarbardhigga shuruudaha sawir-qaadista ee kakan.
Hawlgalka acirbadeynta CTwaxay u baahan tahay maarayn iyo habayn taxadar leh. Kahor intaan la isticmaalin, farsamayaqaanadu waa inay ka hubiyaan cirbadeeyaha wax kasta oo calaamado ah oo cillad ah oo ay xaqiijiyaan in wakiilka isbarbardhiga si sax ah loo raray si looga fogaado caabuqa hawada. Joogitaanka goobta nadiifka ah ee agagaarka aagga duritaanka iyo raacitaanka borotokoolka badbaadada ee habboon waa lama huraan. Intaa waxaa dheer, waxaa muhiim ah in lala socdo bukaanka inta lagu jiro duritaanka wixii falcelin xun ah ee wakiilka ka soo horjeeda. Duriyaasha hal-madaxa ah ayaa ka fudud oo inta badan door bida baarista caadiga ah, halka dual-Head injectors ay aad ugu habboon yihiin sawiridda horumarsan, halkaasoo maamulka isbarbardhigga ee wajiyada badan uu lagama maarmaan yahay.
Noocyada caanka ah ee cirbadaha CT-ga waxaa ka mid ah MEDRAD (by Bayer), Guerbet, iyo Nemoto, kuwaas oo bixiya moodooyinka hal-hal iyo laba-madaxa ah. Tusaalaha MEDRAD Stellant, tusaale ahaan, waa mid si weyn loo isticmaalo oo caan ku ah isku halaynta iyo is-dhex galka saaxiibtinimo ee adeegsadaha, halka Nemoto's Dual Shot taxane uu bixiyo awood dual-Head heer sare ah. Duritaannadan waxaa sida caadiga ah lagu iibiyaa qaybiyeyaasha la oggol yahay ama si toos ah wax-soo-saarayaasha waxaana loogu talagalay inay si aan kala go 'lahayn ula shaqeeyaan noocyo kala duwan oo CT scanner ah, hubinta in la waafajiyo iyo waxqabadka la hagaajiyay ee baahiyaha sawirka caafimaadka.
Ilaa 2019, LnkMed wuxuu soo bandhigay Honor C-1101 (Hal Head CT Injectoriyo Honor C-2101 (Durida Madax-Labada ah ee CT-ga), labaduba waxay muujinayaan tignoolajiyada tooska ah ee loogu talagalay inay taageerto borotokoolka bukaanka ee gaarka ah iyo baahiyaha sawirida ee ku habboon.
Duriyaashan waxaa loo farsameeyay si ay u hagaajiyaan una wanaajiyaan socodka shaqada CT. Waxay ka kooban yihiin hab-habayn degdeg ah oo loogu talagalay rarista walxaha ka soo horjeeda iyo isku xirka khadka bukaanka, hawl lagu dhammayn karo wax ka yar laba daqiiqo. Taxanaha Maamuuska waxa uu isticmaalaa 200-mL sirinji waxana uu ku daraa tignoolajiyada muuqaalka dareeraha saxda ah iyo saxnaanta duritaanka, taas oo u sahlaysa isticmaalayaasha in ay wax ku bartaan tababbarka ugu yar.
LnkMed'sNidaamyada duritaanka CTu soo bandhig faa'iidooyin kala duwan oo loogu talagalay isticmaaleyaasha, sida qaabeynta hal-tallaabo ee heerka socodka, mugga, iyo cadaadiska, iyo sidoo kale awoodda baaritaannada joogtada ah ee laba-xawaaraha ah si loo ilaaliyo xoojinta wakiilka isbarbardhigga ee xasilloonida baarista CT-ga ee wareegyada badan. Tani waxay kaa caawinaysaa muujinta sifada halbowlaha iyo dhaawaca oo faahfaahsan. Iyadoo maskaxda lagu hayo waarta, cirbadaha ayaa leh naqshado aan biyuhu lahayn oo loogu talagalay xasilloonida dheeraadka ah iyo hoos u dhigista khatarta daadinta. Xakamaynta shaashadda taabashada iyo hawlaha otomaatiga ah waxay kor u qaadaan hufnaanta socodka shaqada, taas oo keenta in qalabku yaraado waqti ka dib, iyaga oo ka dhigaya maalgashi dhaqaale.
Xirfadlayaasha daryeelka caafimaadka, nooca dual-head injector model wuxuu u oggolaanayaa isbarbardhigga isku mar ah iyo irbado milix ah oo leh saamiyo kala duwan, taasoo kor u qaadaysa hufnaanta sawirka ee labada halbowle. Habkani waxa uu hubinayaa in dheelli tiran ee u dhexeeya hawo-mareenada midig iyo bidix, waxa ay yaraynaysaa artifacts, waxa ayna u ogolaataa in si cad loo arko halbowlayaasha wadnaha iyo halbowlayaasha saxda ah ee hal sawir, hagaajinta saxnaanta ogaanshaha.
