Itomography siba ngekhompyutha zobuchopho, isifuba kwisisu, imiphunga, amalungu esiswini

Ukusebenza konyango uxhomekeke ngokupheleleyo ukuchaneka uxilongo. Kudla ngokuba njalo-"iimposiso yonyango" xa umntu uqalisa ukuphilisa sisifo eyahlukileyo ngokupheleleyo nokumenza okubi noqhekeko umzimba. unyango phosakeleyo ezimiselweyo kukhokelela kwindlela esinganyangekiyo isifo okanye ukufa. Kuthelekiswa kutsha nje amayeza lalisetyenziswa Itomography siba ngekhompyutha, evumela ukuxilongwa.

le nqubo

Yintoni na loo Itomography ngekhompyutha? Le ndlela eliphezulu-zobugcisa luphawulwa ziluncedo olukhulu kwaye ngendlela ekhethekileyo. Kulo mzekelo, ngesiphumo ugqirha ngokukhawuleza kakhulu ngexesha iinkqubo ezisemgangathweni.

yindlela kwezinto ngekhompyutha Itomography? Ngexesha yakhe etafileni isigulane kufuneka ulele kuwo luqala ihamba kakuhle kwaye ngokucotha. Ngeenxa zonke ngendlela efanayo ukutshintsha ityhubhu X-ray kunye detectors abekwe akwimiganyana kumphezulu wayo.

Izixhobo iyakwazi yokuqaphela yamathumba ubungakanani elincinane kakhulu, ukuya ku-1 mm. Oku kukuvumela ukuba ukuchonga ngokukhawuleza kunye nonyango somhlaza. Uvavanyo omnye kummandla yokwakheka yenziwa ukuba imizuzu emi-5, yaye laser camera owenza imifanekiso esibanzi.

ukusebenza okuphawuleka ziphunyelelwe ngesantya esiphezulu-64 benga yabavavanyi mihla - radiation kwinqanaba elisezantsi wavelisa imifanekiso emacala-mabini ze-ntathu eliphezulu kakhulu.

ubungqina

Itomography Ukonakala iyafuneka kwezi meko zilandelayo:

• uphando Brain, apho ugqirha uyakwazi ukubona izabelo stroke kunye imithambo yegazi owenzakeleyo;
• efumanise ukudumba kwi sinuses paranasal;
• ukumisela ukubunjwa kubangela iindawo entanyeni nkovu;
• isiqinisekiso kwesifo phambi utyando esiswini;
• efumanise utshintsho emiphungeni;
• isifo Ithemba intervertebral.

buhle

Ukonakala CT kuneengenelo ezithile phezu iindlela eziqhelekileyo zophando:

• Uvavanyo (ingcaciso) ikhawuleza kakhulu. Xa ixesha elifutshane ixesha ukuyilwa yomfanekiso ethile kummandla yokwakheka, apho umgangatho umfanekiso liphezulu kakhulu.
• imifanekiso Spatial 3D zichanile ngakumbi, yaye imifuziselo-ntathu zibonisa indawo oluthile ngezifo. Ukusebenzisa ubuchule scan helical ehlola Umthambo kwemithambo ukuchonga ezityeni, ubude bawo, nokunciphisa.
• Non-invasive kuthelekiswa ne myelography, ventriculography.
• Imifanekiso ayibekwanga nezinto ezibonakalayo ukusuka yegazi.
• Xa kuthelekiswa ne Itomography yesiqhelo kuncitshiswa sesichengeni nomonde ku-X-reyi.

Njani na indlela?

iiyure ezi-4 phambi kokuba Uvavanyo lwenziwa, awukwazi ukusela nidle. Ngamanye amaxesha isigulane kufuneka phambi koviwo amalungu ezithile sisele arhente umahluko.

Ukwenza bahlolwa ezijikeleze CT, isigulane kufuneka ulale phantsi etafileni, leyo ezinokususwa, ngoko ke ezityikitywe kwitonela ekhethekileyo. Ukuba ziphandwe kakuhle ngakumbi, itafile axhotyiswe iirholithi ezizodwa kunye pads. Oku kunceda ngethuba loviwo ukuba anciphise intshukumo yalo imifanekiso baphuma hayi kufiphale okanye grainy.

Abo izigulane ngenxa yesizathu esithile akanakuxoka cwaka ixesha elide yaye ixesha elifutshane ukubamba umoya, nadlamkisayo zabo elawulwa.

Kwelinye igumbi ke sisikhululo computer, emva enqamleza ugqirha-injineli, esebenzisa ikhusi umphathi isithwebuli kwaye unika isikhokelo nomonde.

Itomography siba ngekhompyutha kuqwalaselwa kakhulu ekhuselekileyo. Ngoxa inkqubo yoviwo isigulane lifumana imali encinane-X reyi, kodwa incinane kangangokuba ingabangeli nawuphi na umonakalo emzimbeni.

Izimo

Kukho amathuba uxabane nawo, xa isigulane ilawulwa yiarhente koko, okanye umthomalalisi.

Ukuba isigulane unesifo somoya, isifo seswekile, isifo sezintso, lengqula okanye isifo sentliziyo, umele qiniseka ukuba wazise ugqirha wakho.

Le nkqubo contraindicated abafazi abakhulelweyo. Ukuba wenziwa kwimeko kwesigubungelo isisu elikhokelayo sihlangu sibalulekile kuyimfuneko. Kwakhona Akuvunyelwe kulibhala abo izigulane kufuneka pacemakers, ukuxilongwa ferromagnetic nezinobunzima ngaphezu kwama-130 kg.

Uviwo lwe kwisisu

Ukonakala Itomography ngekhompyutha ze kwisisu sikuvumela ukuba ubone umfanekiso ocacileyo multi-umaleko amalungu ezifana udakada, isibindi, injeke kunye nabanye. Sisisebenzise kwimeko ukuba isigulane ikhalazela iintlungu kwi isinqe, isisu, kwaye kwezinye izifo emathunjini amancinci kunye colon.

Ukongeza, inkqubo eyimfuneko ukugula:

• appendicitis, diverticulitis, pyelonephritis, amatye esinyini kunye nezintso;
• isibindi kwesibindi, pancreatitis, ukopha ngaphakathi, polyp kunye nokudumba ethunjini;
• yamathumba umhlaza we kwisisu;
• izifo kwiindawo nkovu kunye imithambo yegazi.

Itomography siba ngekhompyutha ze esiswini lwenziwa nokusetyenziswa imbopheleleko yenu arhente umahluko.

loviwo lung

Le nkqubo iyimfuneko ukulungiselela ekufumanekeni umhlaza wemiphunga metastases. Ukonakala ngekhompyutha lung umfanekiso wabelwa ukuba kukho zonke iimpawu zomhlaza ezi amalungu, kunye X-ray akazange akwazi ukunika ulwazi oluchanekileyo malunga naloo nto. Ukongeza, uhlolo kumiselwe isifo sephepha, amathumba umphunga, cysts umphunga ekumfimfitheni, sarcoidosis, inyumoniya.

Phambi yokuphumeza inkqubo, isigulana ilawulwa yiarhente umahluko emthanjeni equlethe iodine. Ukuba kuthetha kukho nokwaliwa, kufuneka wazise ugqirha wakho.

Ukuhlolisisa yobuchopho

I helical Itomography ayifum zobuchopho isetyenziswa ngokubanzi moshilongo yokwenzakala kakhulu kwaye kakhulu kunene entloko, kunye noxinzelelo intracranial ophezulu, utshintsho kwegazi. Isixhobo uyakwazi ukubona iimeko lwezidumbu (nangezilonda, amathumba, ngomlomo), apho malunga tomograph eqhelekileyo ayibonakali. Ukusebenzisa le nkqubo kwandisa amathuba lokubhaqa nasekunqandeni kwamalungu omzimba nokuhlaselwa yintliziyo.

Ukongeza, i-scan helical iyafuneka kwezi meko zilandelayo:

• ukumisela izinto ezibangela yintloko, ukushwabana ngesiquphe, ngamaxesha pomrachneniya bengasenasazela iindidi ongaboniyo, waphula umthetho uvakalelo kweendawo ezithile umzimba;
• ukuba kukho urhano kukho ithumba ebuchotsheni, aortic kwemithambo komsipha, ukopha intracranial;
• ukuseka kwekhono wendlebe yangaphakathi kwimeko ukungase-;
• Ukuba ufuna isicwangciso ukulungiselela umsebenzi oluzayo nokuvavanya impumelelo yokusebenza kwi ingqondo;
• ukuchonga iindawo ezonakeleyo ingqondo.

Ngamanye amaxesha iimviwo ingqondo ufuna arhente koko, leyo lula kakhulu ukuchongwa cysts, umonakalo atherosclerotic, nangezilonda, metastases, egazi.

Uviwo lwe kwisisu thoracic

Ukonakala CT Isifuba eyenziweyo ukubona isifo nakujoliso olutsha fistulas bronchopleural kunye ukuqanda bronchiectasis. Le nkqubo ikuvumela kakuhle kakhulu fumana nethumba, umsantsa okanye emva komnye emithanjeni, ukuba ukuchonga tshintsho nkovu node.

wasebenzisa ngempumelelo onjalo koviwo Oncology, eyenza ukuba ukuhlola imeko umhlaza, ukumisela imida yayo kunye nobukhulu. Kwezinye iimeko, umntu Itomography helical iboniswe ekufunyanisweni lwamaqumrhu angaphandle, ukusekwa oonobangela ukuphelelwa umoya okanye ubunzima ligwinya.

isiphelo

Ngaloo ndlela, saya ayinakubalwa Itomography yindlela mihla woviwo amasebe awohlukeneyo, evumela ngokuchanileyo ukuseka uxilongo echanekileyo. ithamo imisebe kolu phando lincinane kangangokuba musa esingenakubangela naliphi na ukwenzakalisa umntu, ngoko musa ukuboyika nkqubo.
