Kwicandelo lemifanekiso yezonyango, iityhubhu ze-X-ray kunye nee-CT scanners ziiteknoloji ezimbini eziphambili eziye zaguqula indlela yokuxilongwa. Nangona zombini ezi zixhobo zisebenzisa ii-X-ray ukujonga izakhiwo zangaphakathi zomzimba womntu, zisebenza ngokwahlukileyo kwaye zinemisebenzi eyahlukileyo. Ukuqonda umahluko phakathi kweetyhubhu ze-X-ray kunye nee-CT scanners kubalulekile kubasebenzi bezonyango nakwizigulane kuba kuchaphazela ukukhetha kwabo iteknoloji efanelekileyo yokufota kwiimfuno zabo zeklinikhi.
Iityhubhu ze-X-ray: Iziseko
An Ityhubhu ye-X-reyisisixhobo esivelisa ii-X-reyi ngokukhawulezisa ii-electron size siziqondise kwizinto ezijoliswe kuzo, ezidla ngokwenziwa nge-tungsten. Xa ezi electron zinamandla aphezulu zingqubana nethagethi, zivelisa ii-X-reyi ezinokungena emzimbeni kwaye zenze umfanekiso kwifilimu okanye kwisixhobo sokufumanisa ngedijithali. Imifanekiso ye-X-reyi yendabuko isetyenziselwa ikakhulu ukuhlola amathambo, ukubona ukwaphuka, kunye nokuxilonga iimeko ezifana ne-pneumonia okanye iithumba zesifuba.
Iingenelo eziphambili zeetyhubhu ze-X-ray kukukhawuleza kwazo nokusebenza kakuhle. Uvavanyo oluqhelekileyo lwe-X-ray luthatha imizuzu embalwa kuphela ukugqitywa, nto leyo eyenza ukuba lube lolona lufanelekileyo kwiimeko ezingxamisekileyo. Ukongeza, oomatshini be-X-ray ngokubanzi bafumaneka lula kwaye bangabizi kakhulu kunee-CT scanners, nto leyo eyenza ukuba zibe sisixhobo esiqhelekileyo, esiphambili somfanekiso kwiindawo ezininzi zonyango.
Ii-CT scanners: inyathelo eliya phambili
Kwelinye icala, ii-scanner ze-computed tomography (CT) ziye zayinyusa iteknoloji yokufota ziye kwinqanaba elitsha. Ii-CT scanners zisebenzisa ityhubhu ye-X-ray ejikelezayo ukufota imifanekiso emininzi kwiikona ezahlukeneyo zomzimba. Le mifanekiso emva koko icutshungulwa yikhompyutha ukwenza iziqwenga zomzimba ezinqamlezileyo, zibonelela ngembono eneenkcukacha ngakumbi yezakhiwo zangaphakathi kune-X-ray yemveli yokufota.
Iinkcukacha eziphuculweyo ezibonelelwa zii-CT scans ziluncedo kakhulu ekuxilongeni iimeko ezinzima, ezifana nokwenzakala kwangaphakathi, umhlaza, kunye nezifo ezichaphazela izicwili ezithambileyo. Ii-CT scans zinokutyhila ulwazi malunga namalungu omzimba, imithambo yegazi, kwaneethumba ezisenokungabonakali kwi-X-rays eqhelekileyo. Nangona kunjalo, olu nyuko lweenkcukacha luza nexabiso; ii-CT scans ngokubanzi zibandakanya ukuvezwa okukhulu kwimitha kune-X-ray imaging yesiqhelo.
Umahluko omkhulu kwimifanekiso
Umgangatho womfanekiso kunye neenkcukacha: Omnye womahluko obalulekileyo phakathi kweetyhubhu ze-X-ray kunye nee-CT scanners linqanaba leenkcukacha kwimifanekiso eziyivelisayo. Ii-X-rays zibonelela ngombono oneemilinganiselo ezimbini, ngelixa ii-CT scans zibonelela ngemifanekiso enemilinganiselo emithathu enokwakhiwa ngokutsha ibe ziindlela ezahlukeneyo, nto leyo evumela uvavanyo olupheleleyo lwendawo ekujoliswe kuyo.
Ukuvezwa kwimithaNjengoko bekutshiwo ngaphambili, ii-CT scans zihlala zibeka izigulane kumanqanaba aphezulu emitha kunee-X-rays eziqhelekileyo. Le nto ibaluleke kakhulu xa kujongwa iingozi kunye neenzuzo zendlela nganye yokufota, ingakumbi kubantu abasesichengeni njengabantwana okanye izigulane ezifuna ii-scan ezininzi.
Iimpawu zokusetyenziswaIityhubhu ze-X-ray zihlala zisetyenziselwa uvavanyo olulula, njengokujonga amathambo aphukileyo okanye usulelo. Ngokwahlukileyo koko, ii-CT scanners zilungele ngakumbi imingeni enzima yokuxilonga, njengokuvavanya iintlungu zesisu, ukufumanisa amathumba, okanye ukucwangcisa utyando.
Ixabiso kunye nokufikeleleka: Oomatshini be-X-reyi ngokubanzi baxabisa kancinci kwaye bafumaneka ngokubanzi kwiindawo ezahlukeneyo zonyango, kuquka amagumbi okulaliswa kunye namasebe ongxamiseko. Ii-CT scanners, nangona zibonelela ngezakhono zokuthatha imifanekiso ezikumgangatho ophezulu, zibiza kakhulu kwaye zisenokungafumaneki lula kuzo zonke iindawo zonyango.
ukuququmbela
Ngamafutshane, zombiniIityhubhu ze-X-raykunye nee-CT scanners zidlala indima ebalulekileyo kwimifanekiso yezonyango, kwaye nganye ineenzuzo zayo kunye nemida yayo eyahlukileyo. Ukuqonda umahluko phakathi kwezi teknoloji zimbini kunokunceda ababoneleli bezempilo ukuba benze izigqibo ezinolwazi malunga nokuba yeyiphi indlela yokufota efanelekileyo kwizigulane zabo. Njengoko iteknoloji iqhubeka ihambela phambili, ukuhlanganiswa kwe-X-ray kunye ne-CT imaging kusenokwenzeka ukuba kuqhubeke nokukhula, okuphucula ngakumbi amandla okuxilonga kunye nokhathalelo lwezigulane.
