Makina ojambulira a Computed Tomography (CT) ndi zida zapamwamba zojambulira zithunzi zomwe zimapereka zithunzi zatsatanetsatane za kapangidwe ka mkati mwa thupi. Pogwiritsa ntchito ma X-ray ndi ukadaulo wa makompyuta, makinawa amapanga zithunzi zokhala ndi zigawo kapena "zidutswa" zomwe zitha kusonkhanitsidwa kukhala chithunzi cha 3D. Njira ya CT imagwira ntchito poyendetsa kuwala kwa X-ray m'thupi kuchokera mbali zosiyanasiyana. Kenako kuwala kumeneku kumazindikirika ndi masensa omwe ali mbali inayo, ndipo detayo imakonzedwa ndi kompyuta kuti ipange zithunzi zapamwamba za mafupa, minofu yofewa, ndi mitsempha yamagazi. Kujambula kwa CT ndikofunikira kwambiri pozindikira matenda osiyanasiyana, kuyambira kuvulala mpaka khansa, chifukwa cha kuthekera kwake kupereka zithunzi zomveka bwino komanso zatsatanetsatane za kapangidwe ka mkati.
Makina ojambulira a CT amagwira ntchito polola wodwalayo kugona patebulo lokhala ndi injini lomwe limasunthira mu chipangizo chachikulu chozungulira. Pamene chubu cha X-ray chikuzungulira wodwalayo, makina ojambulira amajambula ma X-ray omwe amadutsa m'thupi, omwe amasinthidwa kukhala zithunzi pogwiritsa ntchito ma algorithms apakompyuta. Opaleshoniyi ndi yachangu komanso yosavulaza, ndipo ma scan ambiri amachitidwa mkati mwa mphindi zochepa. Kupita patsogolo kwakukulu muukadaulo wa CT, monga kuthamanga kwa kujambula zithunzi mwachangu komanso kuchepa kwa kuwala kwa dzuwa, kumapitilizabe kupititsa patsogolo chitetezo cha wodwala komanso magwiridwe antchito ozindikira matenda. Mothandizidwa ndi makina ojambulira amakono a CT, asing'anga amatha kuchita angiography, virtual colonoscopy, ndi kujambula kwa mtima, pakati pa njira zina.
Makampani otsogola pamsika wa CT scanner ndi GE Healthcare, Siemens Healthineers, Philips Healthcare, ndi Canon Medical Systems. Mtundu uliwonse wa makampaniwa umapereka mitundu yosiyanasiyana yopangidwira kukwaniritsa zosowa zosiyanasiyana zachipatala, kuyambira kujambula zithunzi zapamwamba mpaka kujambula mwachangu thupi lonse. Mndandanda wa GE's Revolution CT, mndandanda wa Siemens' SOMATOM, mndandanda wa Philips' Incisive CT, ndi mndandanda wa Canon's Aquilion zonse ndi njira zodziwika bwino zomwe zimapereka ukadaulo wapamwamba. Makina awa amapezeka kuti mugule mwachindunji kuchokera kwa opanga kapena kudzera mwa ogulitsa zida zamankhwala ovomerezeka, ndipo mitengo imasiyana kwambiri kutengera mtundu, luso lojambula zithunzi, ndi dera.
Jakisoni wa CTs: Injekitala imodzi ya CTndiJakisoni wa Mutu Wawiri wa CT
Majakisoni a CT, kuphatikizapo njira za Single-Head ndi Dual-Head, amagwira ntchito yofunika kwambiri popereka mankhwala osiyanitsa panthawi ya CT scan. Majakisoni awa amalola kuwongolera bwino jakisoni wa zinthu zosiyanitsa, zomwe zimapangitsa kuti mitsempha yamagazi, ziwalo, ndi zina ziwoneke bwino pazithunzi zomwe zatuluka. Majakisoni a Single-Head amagwiritsidwa ntchito popereka mankhwala osiyanitsa mosavuta, pomwe majakisoni a Dual-Head amatha kupereka mankhwala kapena mayankho awiri osiyana motsatizana kapena nthawi imodzi, zomwe zimapangitsa kuti kusinthasintha kwa kuperekedwa kwa mankhwala osiyanitsa kukhale kovuta kwambiri pakufunika kwa zithunzi zovuta.
Ntchito yajekeseni ya CTImafunika kuigwira bwino komanso kuikonza mosamala. Asanagwiritse ntchito, akatswiri ayenera kuyang'ana jekeseniyo kuti aone ngati pali zizindikiro zilizonse zosagwira ntchito bwino ndikuwonetsetsa kuti jekeseniyo yayikidwa bwino kuti apewe kutsekeka kwa mpweya. Kusunga malo opanda banga mozungulira malo obayira jakisoni ndikutsatira njira zoyenera zotetezera ndikofunikira. Kuphatikiza apo, ndikofunikira kuyang'anira wodwalayo nthawi yonse yobayira jakisoniyo kuti aone ngati pali zotsatirapo zoyipa kwa jekeseniyo. Majekeseni a Mutu umodzi ndi osavuta ndipo nthawi zambiri amakondedwa pakupanga ma scan nthawi zonse, pomwe majekeseni a Mutu umodzi ndi oyenera kwambiri kujambula zithunzi zapamwamba, komwe kumafunika kupereka jekeseni wamitundu yambiri.
Mitundu yotchuka ya ma injector a CT ikuphatikizapo MEDRAD (yopangidwa ndi Bayer), Guerbet, ndi Nemoto, omwe amapereka mitundu ya single-Head komanso dual-Head. Mwachitsanzo, MEDRAD Stellant injector imagwiritsidwa ntchito kwambiri ndipo imadziwika chifukwa cha kudalirika kwake komanso mawonekedwe ake osavuta kugwiritsa ntchito, pomwe mndandanda wa Nemoto's Dual Shot umapereka mphamvu zapamwamba zojambulira dual-Head. Ma injector awa nthawi zambiri amagulitsidwa kudzera mwa ogulitsa ovomerezeka kapena mwachindunji kuchokera kwa opanga ndipo adapangidwa kuti azigwira ntchito bwino ndi mitundu yosiyanasiyana ya CT scanner, kuonetsetsa kuti ikugwirizana komanso magwiridwe antchito abwino pazosowa za zithunzi zachipatala.
Kuyambira mu 2019, LnkMed yakhazikitsa Honor C-1101 (Injector ya CT ya Mutu Umodzi) ndi Honor C-2101 (Jakisoni wa CT wa Mitu Yawiri), zonse zili ndi ukadaulo wodzipangira wokha wopangidwira kuthandiza njira za wodwala payekha komanso zosowa zojambula zomwe zakonzedwa.
Majekeseni awa adapangidwa kuti azitha kusintha ndikuwonjezera magwiridwe antchito a CT. Ali ndi njira yokhazikitsira mwachangu yokweza zinthu zosiyanitsa ndi kulumikiza mzere wa wodwala, ntchito yomwe imatha kumalizidwa mu mphindi zosakwana ziwiri. Mndandanda wa Honor umagwiritsa ntchito sirinji ya 200-mL ndipo umaphatikizapo ukadaulo wowunikira bwino madzi ndi kulondola kwa jakisoni, zomwe zimapangitsa kuti ogwiritsa ntchito azitha kuphunzira mosavuta popanda maphunziro ambiri.
LnkMed'sMakina ojambulira a CTamapereka maubwino osiyanasiyana kwa ogwiritsa ntchito, monga kukonza kwa sitepe imodzi kuti aone kuchuluka kwa madzi, voliyumu, ndi kuthamanga, komanso kuthekera kojambula zinthu mopitirira muyeso kawiri kuti zisunge kuchuluka kwa zinthu zosiyanitsa zinthu kukhala kokhazikika mu multi-slice spiral CT scans. Izi zimathandiza kuwulula zambiri zokhudza mitsempha ndi zilonda. Zopangidwa ndi kulimba m'maganizo, ma injectors ali ndi mapangidwe osalowa madzi kuti awonjezere kukhazikika komanso kuchepetsa chiopsezo cha kutuluka kwa madzi. Zowongolera pazenera logwira ntchito ndi ntchito zodziyimira pawokha zimawonjezera magwiridwe antchito, zomwe zimapangitsa kuti chipangizocho chisamawonongeke pakapita nthawi, zomwe zimapangitsa kuti chikhale chotsika mtengo.
Kwa akatswiri azaumoyo, njira yopangira jakisoni wa mutu umodzi imalola jakisoni wosiyanitsa ndi wa saline nthawi imodzi pamlingo wosiyanasiyana, zomwe zimapangitsa kuti zithunzi ziwoneke bwino m'ma ventricle onse awiri. Izi zimapangitsa kuti pakati pa ma ventricle akumanja ndi akumanzere pakhale kuchepetsedwa kwabwino, zimachepetsa zinthu zakale, komanso zimathandiza kuti mitsempha ya mtima ndi ma ventricle akumanja aone bwino bwino mu scan imodzi, zomwe zimapangitsa kuti kulondola kwa matenda kukhale kolondola.
