Kwinkalo yomfanekiso wezonyango, iityhubhu ze-X-reyi kunye nee-CT scanner zimbini iiteknoloji eziphambili ezitshintshe indlela yokuxilongwa. Nangona zombini izixhobo zisebenzisa iiX-reyi ukujonga izakhiwo zangaphakathi zomzimba womntu, zisebenza ngokwahlukileyo kwaye zinosetyenziso olwahlukileyo. Ukuqonda umahluko phakathi kweetyhubhu ze-X-reyi kunye nee-CT scanners kubalulekile kubo bobabini abasebenzi bezonyango kunye nezigulana kuba kuchaphazela ukhetho lwabo lobuchwepheshe bomfanekiso obufanelekileyo kwiimfuno zabo zeklinikhi.
Imibhobho ye-X-Ray: Iziseko
An Umbhobho weX-raysisixhobo esivelisa ii-X-reyi ngokukhawulezisa ii-elektroni nezizikhokelela kwinto ekujoliswe kuyo, edla ngokwenziwa nge-tungsten. Xa ezi electron zinamandla amakhulu zingqubana noko kujoliswe kuko, zivelisa iiX-reyi ezinokungena emzimbeni zize zenze umfanekiso kwifilimu okanye kwisixhobo sokubona idijithali. Imifanekiso yeX-reyi yesiNtu isetyenziselwa ukuxilonga amathambo, ukubona iindawo ezaphukileyo, kunye nokuxilonga iimeko ezifana nenyumoniya okanye amathumba esifuba.
Iinzuzo eziphambili zeetyhubhu ze-X-ray zisantya kunye nokusebenza kwazo. Uviwo oluqhelekileyo lweX-reyi luthatha imizuzu embalwa kuphela ukulugqiba, lulwenza lube lulungele iimeko zonxunguphalo. Ukongezelela, oomatshini beX-reyi ngokuqhelekileyo bafumaneka lula yaye bangabizi kakhulu kunee-CT scanner, nto leyo ebenza babe sisixhobo esiqhelekileyo, esingaphambili kumaziko onyango amaninzi.
CT scanners: inyathelo eliya phambili
I-Computed tomography (CT) scanners, kwelinye icala, ithathe iteknoloji ye-imaging kwinqanaba elitsha. I-CT scanners isebenzisa ityhubhu yeX-reyi ejikelezayo ukuze ibambe imifanekiso emininzi kwii-engile ezahlukeneyo zomzimba. Le mifanekiso icutshungulwa yikhompyuter ukuze yenze izilayi zomzimba ezinqamlezayo, zibonelela ngombono othe kratya wezakhiwo zangaphakathi kune-X-ray yendabuko.
Iinkcukacha eziphuculweyo ezibonelelwa yi-CT scans ziluncedo kakhulu ekuxilongeni iimeko ezinzima, ezinjengokwenzakala kwangaphakathi, umhlaza, kunye nezifo ezichaphazela izicubu ezithambileyo. I-CT scan inokutyhila ulwazi malunga namalungu, imithambo yegazi, kunye namathumba anokuthi angabonakali kwii-X-reyi eziqhelekileyo. Nangona kunjalo, oku kwanda kweenkcukacha kuza kwixabiso; I-CT scans ngokubanzi ibandakanya ukuvezwa kwemitha ephezulu kune-X-reyi yesiqhelo.
Umahluko omkhulu kwimifanekiso
Umgangatho womfanekiso kunye neenkcukacha: Omnye owona mahluko ubalulekileyo phakathi kweityhubhu zeX-reyi kunye ne-CT scanners linqanaba leenkcukacha kwimifanekiso eziyenzayo. Ii-X-rays zibonelela ngeembono ezimbini-dimensional, ngelixa ii-CT scans zibonelela ngemifanekiso emithathu-ntathu enokuthi iphinde ihlaziywe kwiindiza ezahlukeneyo, evumela ukuba kuhlolwe ngokubanzi indawo ekujoliswe kuyo.
Ukuba sesichengeni ngemithaNjengoko bekutshiwo ngaphambili, ii-CT scans zidla ngokubeka izigulana kumanqanaba aphezulu emitha yemitha kunee-X-reyi eziqhelekileyo. Lo mba ubalulekile xa kuqwalaselwa imingcipheko kunye neenzuzo zendlela nganye yokucinga, ngakumbi kubantu abasesichengeni njengabantwana okanye izigulana ezifuna iskeni ezininzi.
Iimpawu zokusetyenziswa: Iityhubhu zeX-reyi ziqhele ukusetyenziselwa uvavanyo olulula, olufana nokujonga amathambo aphukileyo okanye usulelo. Ngokwahlukileyo koko, i-CT scanners ifanelekele ngakumbi imingeni enzima yokuxilonga, njengokuvavanya iintlungu zesisu, ukufumanisa amathumba, okanye ukucwangcisa ungenelelo lotyando.
Iindleko kunye nokufikeleleka: Oomatshini be-X-ray ngokuqhelekileyo baxabisa kakhulu kwaye bafumaneka ngokubanzi kwiindawo ezahlukeneyo zokunakekelwa kwezempilo, kubandakanywa izigulane ezingaphandle kunye namasebe angxamisekileyo. Izikena ze-CT, ngelixa zibonelela ngezakhono eziphezulu zokujonga, zibiza kakhulu kwaye zisenokungafumaneki lula kuzo zonke iisetingi zempilo.
ukuququmbela
Ngamafutshane, zombiniImibhobho ye-X-raykunye ne-CT scanners zidlala indima ebalulekileyo kumfanekiso wezonyango, kwaye nganye ineengenelo kunye nemida yayo eyahlukileyo. Ukuqonda umahluko phakathi kwezi teknoloji zimbini kunokunceda ababoneleli bezempilo benze izigqibo ezinolwazi malunga nokuba yeyiphi indlela yokucinga eyona nto ilungele izigulane zabo. Njengoko iteknoloji iqhubeka nokuqhubela phambili, ukuhlanganiswa kwe-X-ray kunye ne-CT imaging kungenzeka ukuba iqhubeke nokuguquka, iphucula ngakumbi amandla okuxilonga kunye nokunyamekela isigulane.
