Kodi makina a CT Scan ndi ati? Chitsogozo chokwanira

Ngati mudakhalako kuchipatala kapena chipatala kuti muchite zachipatala, pali mwayi wabwino womwe mudakumana nawo. Chida choyerekeza cha ter-tech chimagwira ntchito yofunika kwambiri mu mankhwala amakono, kuthandiza madokotala kukhala ndi zomwe zachitika mwatsatanetsatane zomwe zikuchitika mumtima. Koma kodi makina a CT? Zimagwira bwanji? Kodi pali aliyense chifukwa chiyani kuli kofunikira pamankhwala amakono? Chitsogozo chokwanira ichi chidzakuyendetsani pamafunika makina a CT Scan: Kuchokera pazomwe ali ndi momwe amagwirira ntchito zabwino ndi ntchito zake.

 

I. Kodi makina a CT ndi ndani?

Makina a CT Scan, omwe amadziwikanso kuti mphaka (makompyuta a axial Tomography) sakanizi, ndi chida chodziwikiratu chomwe chimaphatikizira makompyuta a X-ray.

 

Ii. Kusiyana pakati pa makina azikhalidwe za X-ray ndi makina a CT Scan

	Makina amakono a X-ray	Makina a CT Scan
Zamakompyuta	Amagwiritsa ntchito mtengo umodzi wa x-ray	Amagwiritsa ntchito ma X-ray mitengo ndi zojambula zambiri
Mtundu Wazithunzi	2d (lathyathyathya, monga chithunzi)	Magawo a Cross-torder (2D)
Mlingo watsatanetsatane	Kusintha kotsika, kuwonetsa chidziwitso chokha cha kapangidwe ka mafupa ndi minofu yofewa	Zithunzi zotha kusintha zomwe zimapereka malingaliro a mafupa, minofu yofewa, ndi ziwalo
Nthawi Yanu	Mwachangu (masekondi ochepa okha)	Motalika (nthawi zambiri mphindi)
Mlingo wa radiation	Nthawi zambiri amachepetsa	Okwera chifukwa cha kutanthauzira kangapo
Ika mtengo	Kugula kotsika ndi kugwirira ntchito	Kugula Kwambiri ndi Kuwononga Ntchito
Ntchito Zodziwika	Mafupa osweka, mayeso a mano, chifuwa x-ray	Kukambirana kwatsatanetsatane kwa ziwalo zamkati, zotupa, mitsempha yamagazi, ubongo
Space Zofuna	Wophinjana	Pamafunika chipinda chokulirapo

      

Iii. Kodi makina a CT Scan amagwira ntchito bwanji?

Mfundo yogwira ntchito yamakina ya CT Scan imazungulira ma X-ray. Nayi kufotokozera kosavuta kwamomwe mungafotokozedwe kwa momwe makina a CT Scan amagwirira ntchito:

1. X-ray chubu kuzungulira

Wodwalayo amaikidwa patebulo lamagalimoto omwe pang'onopang'ono amasunthira kutsegulidwa kozungulira kwa makina a CT Scan. Chubu cha X-ray mosalekeza chimazungulira mozungulira thupi la wodwalayo, kutulutsa ma x-ray.

2. Kuzindikira kwa X-Ray

Ma ray a X-Ray adatulutsa kuchokera ku chubu cha X-ray kudutsa thupi. Ma ray a X-ray amalowetsedwa ndi minyewa yosiyanasiyana pamitengo yosiyanasiyana (minyewa yowirira imatenga ma x-ray). Openya, omwe amakhazikitsidwa mbali ina ya X-ray, amagwira ma X-rays omwe amadutsa thupi.

3. Kutembenuka kwa data

Zowunikira zowunikira zimasandutsa zizindikiro za X-ray kukhala zamagetsi zamagetsi, zomwe zimaperekedwa ndi kompyuta. Kompyutayi imalandira zikwangwani zamagetsi izi ndikuwapangitsa kuti apange zithunzi zatsatanetsatane kapena zigawo zanyumba kapena 'magawo. '

Magawo pawokha amaphatikizidwa mu chithunzi chofanana ndi thupi, kulola ma radiologist kusanthula ziwalo ndi minofu ndikuzama.

 

Iv. Ubwino Wofunika wa Makina a CT Scan

Makina a CT Scan amapereka zabwino zambiri zomwe zimawapangitsa kukhala chida chofunikira kwambiri muzampani zamakono. Zina mwazabwino zimaphatikizapo:

1. Malingaliro osinthika

Chimodzi mwazinthu zabwino kwambiri ndi kuthekera kwawo kupereka zifaniziro zapamwamba. Amatha kudziwa zambiri za anatomical. Mwachitsanzo. Zithunzi zosinthika izi zimati madokotala azithunzi m'maganizo mwazinthu za ziwalo, zomwe zimathandizira popanga zolondola kuchuluka kwa zinthu zosiyanasiyana.

2. Kuthamanga ndi kuchita bwino

CT scans, nthawi zambiri imachitidwa m'mphindi zochepa chabe, ndikufanizira mwachangu ndi njira zina zolingalira ngati mar. Ndi mwayi waukulu, makamaka kwa odwala omwe amawavuta kukhalabe kwa nthawi yayitali kapena omwe ali ndi mankhwala ena.

3. Zambiri

Makina a CT Scan amatha kupanga zithunzi zapadera kuti apatse mawonekedwe a mkati mwazinthu, kuthandiza madokotala kukhala ndi m'maganizo, monga mitsempha, mafupa, ndi ziwalo zokwanira. Zowonjezera, zithunzi zodutsa pamtanda zitha kuphatikizidwa mu mtundu wa mawonekedwe atatu. Izi nthawi zambiri zimagwiritsidwa ntchito pokonzekera maopaleshoni ndi biopsies. Mtundu wamitundu itatu umathandiza m'maganizo madokotala malo enieni, kuonetsetsa kuti njira zimayendetsedwa mosamala.

 

V. Zowonjezera zamankhwala zodziwika bwino za Makina a CT Scan

Makina a CT Scan ndi zida zofunikira pakugwiritsa ntchito mankhwala osiyanasiyana. Mapulogalamu ena omwe amagwiritsidwa ntchito kwambiri ndi:

1. Kuyanjana kwa khansa ndikuwunikira

Kuwunika kwa khansa, makina amakina nthawi zambiri amagwiritsidwa ntchito kuona khansa ziwalo zosiyanasiyana, monga mapapu, chiwindi, kapamba, ndi impso. Pa nthawi yowunikira khansa kapena pambuyo pa chithandizo, makina a CT amagwiritsidwa ntchito potsatira ntchito ya khansa, kuthandiza madokotala kuti ayesetse chotupacho chikuchepa kapena kufalitsa.

2. Matenda a mtima

Ct Angiography (CTA) ndi mawonekedwe apadera a CT. Zimathandizanso akatswiri azachipatala omwe adazindikira mitima, imatchingira m'mawere a coronary, ndi aneirysss osafunikira opaleshoni yopambana.

3. Kuzindikira Matenda Odwala

Mu neurology, makina a CT amagwiritsidwa ntchito pozindikira zosiyanasiyana zokhudzana ndi ubongo komanso dongosolo lamanjenje, zotupa za ubongo, kuvulala kwa ubongo, kuvulala kwa ubongo. Amatha kuthandiza akatswiri amisili amasiyanitsa mitundu yayikulu ya matenda (mwachitsanzo, ischemic sitintroko ndi hemorrhagic sitintroko), yesani kukula kwa matenda (mwachitsanzo, zotupa zonyansa), ndikukonzekera chithandizo choyenera.

4. Matenda a Orthopdic matenda

Mu Orthopedics, makina a CT katswiri nthawi zambiri amagwiritsidwa ntchito kuti adziwe zovuta ndi mafupa, monga mafupa a mafupa, kusokonezeka kwa mafupa, kapena zotupa zam'maso (zonse zoyambira). Amathandizanso pakukonzekera maopaleshoni a Orthopedic ndikuwunika machiritso.

5. Zovuta ndi chisamaliro chadzidzidzi

M'chipinda chadzidzidzi, pomwe mphindi iliyonse ndi yovuta, makina a CT Scan amakhala ndi zida zofunika kwambiri za milandu yovutikira milandu. Amatha kudziwa mwachangu zovulala za moyo zomwe sizingakhale zakunja, monga kutaya magazi kwamkati, kuwonongeka kwa ziwalo, zowonongeka, zadzidzidzi zam'matumbo, ndi zovuta zam'mimba.

 

Vi. Zoopsa ndi malingaliro a makina a CT Scan

Pomwe makina a CT Scan ndi othandiza kwambiri mu diastictics yamankhwala, amakhala ndi zoopsa, makamaka zokhudzana ndi kuwonekera kwa radiation. Nawa malingaliro ochepa:

1. Kuwonetsedwa kwa radiation

Kugwiritsa ntchito makina a CT Scan kumazungulira mozungulira ma X-ray, omwe ndi mawonekedwe a radiation. Ma radiation a Wionight ali ndi kuthekera kuwononga DNA m'maselo, zomwe nthawi zina zimatha kubweretsa chiopsezo chowonjezereka cha zovuta zokhudzana ndiumoyo, monga khansa, kwanthawi yayitali. Ngakhale ma radiation mlingo umodzi wa CT ndi wotsika mtengo, wobwereza kapena wosafunikira amatha kuwonjezera kuwonetsedwa kwanthawi ya munthu kwa munthu. Komabe, mapindu a CT nthawi zambiri amabwera ndi zoopsa, makamaka ngati ndizofunikira kuti mudziwe kapena kuchiza mikhalidwe yayikulu.

2. Anthu apadera

Magulu ena a anthu amafunikira chisamaliro chapadera pankhani ya CT. Amayi oyembekezera ndi chitsanzo chachikulu. Cholinga chachikulu ndikuti ma radiation ochokera ku CT amathetsa mwana wosabadwayo, makamaka pa trimester yoyamba. Kuwonetsedwa kwa radiation kumatha kutsogolera kufooka, malemedwewa akukula, khansa yaubwana, kapenanso zina zotayika. Chifukwa chake, pokhapokha ngati mapindu ake abwera ndi zoopsa zomwe zimachitika chifukwa cha mayi kapena mwana wosabadwa, amayi apakati ayenera kupewa scans, makamaka pamimba kapena pelvis. Njira zina zongopeka, monga maltrasound kapena MRI, nthawi zambiri amagwiritsidwa ntchito kwa odwala apakati.

3..

Othandizira osiyanitsa (utoto) amagwiritsidwa ntchito mu ma CT samalimbikitsa mawonekedwe a mitsempha yamagazi, ziwalo, ndi ziwalo zonyansa. Ngakhale ndizofunikira kwambiri kukonzanso chiwonetsero chazindikilo. Zovuta zazikulu zimaphatikizapo thupi lawo siligwirizana, lomwe limatha kuyambiranso kuyamwa kwambiri anaphylaxis, ndipo poizoni wa impso - makamaka kwa odwala omwe ali ndi vuto la aimpso. Chifukwa chake, kuwonetsetsa kuti chitetezo, chowunikira, chisamaliro cha wodwala matendawa, mphumu, matenda asney, matenda ashuga, ndi mankhwala aposachedwa, ayenera kuchitidwa kale.

 

VII. Mapeto

Makina a CT Scan ndi mwala wapamwamba wa mankhwala amakono ozindikira. Amapanga zifaniziro za thupi mkati mwazinthu za thupi, kuthandiza madokotala omwe amazindikira ndikugwiritsa mitundu, kuchokera ku zowawa ku khansa. Ngakhale zoopsa zomwe zingachitike ndi kuwonekera kwa radiation, maubwino a makina a CT Scan potengera kusinthalika kwakukulu, liwiro lofulumira, ndikudziwitsa zambiri zomwe zimapangitsa kuti zikhale chida chofunikira pazaumoyo.
