Makina a C-arm asintha malingaliro azachipatala ndi mawonekedwe awo apadera komanso kuthekera kowonera nthawi yeniyeni. Monga mwala wapangodya wa ma radiology amakono ndi opaleshoni ya mafupa, mawonekedwe apadera a C-arm ndi zomangamanga zimathandiza kusinthasintha kosayerekezeka pojambula zithunzi za X-ray zapamwamba kwambiri. Nkhaniyi isanthula mwadongosolo zigawo zinayi zazikulu za C - mkono: wophatikiza - mutu wamtundu (jenereta ya X-ray), makina ojambulira, makina owongolera, ndi makina amakina.
1. X-ray Jenereta
Jenereta ya X-ray ndi imodzi mwazinthu zofunika kwambiri pamakina a C-arm. Ndilo udindo wopanga ndi kupereka ma X-ray ofunikira pakujambula.
Gawoli lili ndi:
X-ray Tube Assembly
X-ray chubu ndi mtima wa jenereta. Amatulutsa ma X-ray kudzera pakukondoweza kwamphamvu kwambiri. Kutentha kwapamwamba komanso njira zoziziritsira mwachangu ndizofunikira kuti zisunge magwiridwe antchito panthawi yayitali.
Jenereta wamagetsi apamwamba
Chipangizochi chimagwiritsa ntchito chubu cha X-ray, kutembenuza mphamvu yamagetsi kukhala ma pulse othamanga kwambiri. Kutulutsa kwamagetsi kokhazikika komanso kosasintha ndikofunikira kuti chithunzi chimveke bwino komanso chitetezo.
Pamodzi, zigawozi zimatsimikizira kuti C-arm imapereka chithunzithunzi cholondola komanso chomveka panthawi ya opaleshoni kapena njira zowunikira.
2. Kujambula System
Makina ojambulira amajambula ndikusintha zithunzi za X-ray, kuzisintha kukhala mawonekedwe owoneka komanso ogwiritsidwa ntchito kwa asing'anga. Makina ojambulira apamwamba kwambiri ndi ofunikira kuti adziwe molondola komanso kuzindikira.
Zigawo zazikulu za dongosolo lojambula zithunzi ndi izi:
Image Intensifier kapena Flat Panel Detector
Zida zamakono za C zimagwiritsa ntchito chowonjezera chithunzi kapena chojambulira chojambulira (FPD). FPD ndiyotsogola kwambiri, yopereka kusintha kwakukulu, kusiyanitsa kwabwinoko, komanso kuchepetsedwa kwa ma radiation.
Woyang'anira
Zithunzi zenizeni zenizeni zikuwonetsedwa pazowunikira zapamwamba, zomwe zimathandiza madokotala kuti aziwona thupi la anatomy panthawi ya opaleshoni. Kukonzekera kwapawiri koyang'anira nthawi zambiri kumagwiritsidwa ntchito kuyerekeza zithunzi zamoyo ndi zowonetsera nthawi imodzi.
Imaging Workstation
Malo ogwirira ntchito ndiye makina apakompyuta omwe amakonza, kusunga, ndikuwongolera zithunzi zojambulidwa. Imathandizira ntchito zingapo, kuphatikiza makulitsidwe, kuzungulira, ndi kukulitsa zithunzi kuti muwunike bwino zachipatala.
3. Control System
Dongosolo lowongolera limayang'anira ntchito ndikusintha makina a C-arm panthawi yamayendedwe. Imalola wogwiritsa ntchito kuwongolera kuwonekera, ma angles oyerekeza, ndi magawo adongosolo bwino.
Zigawo zikuphatikizapo:
Gawo lowongolera
Gulu lowongolera lapakati limalola asing'anga kukonza zoikamo zojambula monga nthawi yowonekera, mphamvu ya X-ray, ndi kusungirako zithunzi.
Wowongolera Pamanja
Woyang'anira m'manja amapereka kusinthasintha kwa maopaleshoni kuti agwiritse ntchito mkono wa C kutali kapena m'munda wosabala.
Exposure Switch
Kusintha kwa dzanja kapena phazi kungagwiritsidwe ntchito kuyambitsa kuwonekera kwa X-ray. Izi zimathandizira kuti zikhale zosavuta komanso zimathandizira chitetezo chogwira ntchito pochepetsa kusuntha kosafunikira.
Dongosolo lowongolera mwachilengedwe limapangitsa kuti ntchito ziziyenda bwino komanso zolondola panthawi yachipatala.
4. Makina System
Mapangidwe amakina amathandizira kuyenda ndi kuyika, kuonetsetsa kuti makina ojambulira amatha kuyendetsedwa mosavuta komanso molondola mozungulira wodwalayo.
Zinthu zazikuluzikulu zikuphatikiza:
C-Arm Movement System
Dzanja looneka ngati C limatha kusunthidwa molunjika, mopingasa, komanso mozungulira ma axis ake, zomwe zimapangitsa kuti pakhale ma angles angapo ojambulira. Izi ndizofunikira kuti mupeze malingaliro abwino popanda kumuyikanso wodwalayo.
Mobile Stand yokhala ndi Magudumu
Ma C-arm nthawi zambiri amayikidwa pamapulatifomu okhala ndi mawilo, zomwe zimathandiza kuyenda mkati ndi m'madipatimenti onse. Zotsekera mabuleki zimatsimikizira kukhazikika panthawi yogwira ntchito.
Mechanical Motion Control
Izi zimatanthawuza makina oyendetsa magalimoto omwe amathandizira kuyendetsa bwino komanso kolondola, kuwongolera malo olondola komanso kuchepetsa kuyeserera kwamanja.
Dongosolo lamakina limatsimikizira kusinthasintha, komwe ndikofunikira kuti pakhale zovuta zopangira opaleshoni pomwe nthawi ndi zolondola ndizofunikira.

A C-arm ndi kuphatikiza kwaukadaulo kwa m'badwo wa X-ray, kukonza zithunzi, makina owongolera, ndi uinjiniya wamakina. Kumvetsetsa dongosolo la C-arm kumapangitsa magulu azachipatala kuti azigwiritsa ntchito bwino zida, kukonza kulondola kwa opaleshoni, komanso kupereka zotsatira zabwino za odwala.
Kaya mukugula makina atsopano a C-arm, ogwira ntchito yophunzitsa, kapena mukukweza malo anu oyerekeza azachipatala, kudziwa kapangidwe kake ndikofunikira. Poganizira ntchito ya gawo lililonse, malo amatha kukulitsa kugwiritsidwa ntchito ndikukhalabe ndi miyezo yapamwamba pakujambula ndi kuchitapo kanthu.
