Zigawo Zolondola ndi Chinsinsi cha Kujambula Kwapamwamba Kwambiri

Ogwira ntchito zaumoyo ndi odwala amadalira kujambula kwa maginito resonance (MRI) ndiCT scanukadaulo wosanthula minofu yofewa ndi ziwalo m'thupi, kuzindikira zinthu zingapo kuchokera ku matenda osokonekera kupita ku zotupa m'njira yosasokoneza. Makina a MRI amagwiritsa ntchito mphamvu ya maginito ndi mafunde a wailesi opangidwa ndi makompyuta kuti apange zithunzi zapambali. Choncho, ubwino wa MRI umagwirizana ndi kufanana kwa maginito - ngakhale pang'onopang'ono maginito mkati mwa MRI scanner akhoza kusokoneza munda ndi kuchepetsa ubwino wa chithunzi cha MRI.

Momwe MRI Imagwirira Ntchito Pamwamba

Makina a MRI omwe timawadziwa masiku ano amagwira ntchito pa mfundo ya nuclear magnetic resonance (NMR). Mwachindunji, mamolekyu omwe ali m'thupi la munthu amakhala ndi haidrojeni, ndipo phata la atomu ya haidrojeni imakhala ndi pulotoni imodzi yomwe imakhala ngati maginito okhala ndi pole ya kumpoto ndi kumwera. Pamene mphamvu ya maginito ikugwiritsidwa ntchito, ma spins awo, katundu wa tinthu tating'onoting'ono tating'onoting'ono, timagwirizanitsa mofanana. Wodwala akamayikidwa mkati mwa chubu cha scanner ya MRI, ma spin a ma protoni omwe ali m'mamolekyu amthupi amalumikizana, onse kuyang'ana mbali imodzi, monga gulu loguba lomwe likuchita pabwalo la mpira.

Komabe, ngakhale kusiyana kwakung'ono kwambiri kwa maginito kungayambitse ma protoni kuti agwirizane m'njira zosiyanasiyana, zomwe zikutanthauza kuti sangayankhe mofanana ndi kusonkhezera. Zosiyanasiyana izi zitha kusokoneza ma algorithms ozindikira. Zoona zake, kuzindikirika kosakhazikika kumeneku, phokoso lambiri, kapena kusinthasintha kwachisawawa kwamphamvu yazizindikiro kungayambitse zithunzi zonyansa. Chithunzi chochepa kwambiri chikhoza kuchititsa kuti munthu adziwe kuti ali ndi matenda olakwika ndipo, chifukwa chake, kusankha mankhwala olakwika.

(Monga tonse tikudziwira, kujambula kuyenera kumalizidwa kudzera mu njira yosiyanitsa, ndipo iyenera kulowetsedwa m'thupi la wodwalayojekeseni wothamanga kwambirikomansosyringe ndi machubu. LnkMed ndi kampani yopanga yomwe imagwira ntchito popereka zinthu zosiyanitsa. Zake paokha anayambaMRIkusiyanajekeseni, CT scan injectorndiDSA injectorzagawidwa m'zipatala m'mayiko ambiri kuti apereke chithandizo chamankhwala. Majekeseni athu ndi osalowa madzi, osinthika kwambiri, komanso osavuta kuti ogwira ntchito zachipatala azisuntha ndikugwira ntchito; amagwiritsa ntchito kulankhulana kwa Bluetooth, woyendetsa sayenera kuthera nthawi yochuluka pa kuika ndi kukhazikitsa; zida zosinthira zaulere ngati ntchito yogulitsa ikatha. LnkMed yadzipereka kupereka zinthu ndi ntchito zapamwamba kwambiriradiology ndi kujambula.

Kusankha Zinthu Zofunikira Ndikofunikira

Kukhalapo kwa zigawo za maginito mumsewu wa MRI scanner kumatha kusokoneza kufanana kwa munda, ndipo ngakhale pang'ono kwambiri maginito amatha kukhudza khalidwe la chithunzi cha MRI. Zotsatira zake, ndikofunikira kuti opanga zida zamankhwala azifunafuna zida, monga ma capacitor okhazikika, ma trimmer capacitor, ma inductors, ndi zolumikizira, zomwe zimapangidwa kuchokera kuzitsulo zoyera kwambiri zopanda maginito oyezeka.

Kutsatira izi kumayamba ndikutsata mosamalitsa njira zoyeserera komanso zoyeserera, komanso maziko olimba aukadaulo waukadaulo wazinthu. Mwachitsanzo, ma capacitor ambiri amapangidwa ndi chotchinga cha nickel kuti asunge kusungunuka; komabe, maginito a faifi tambala amapangitsa kuti capacitor ikhale yosayenera kugwiritsidwa ntchito pojambula zithunzi. Momwemonso, mkuwa wamalonda, chinthu china chomwe chimagwiritsidwa ntchito pafupipafupi, sichiyeneranso kuchita izi.

Kusamalitsa kotereku mwatsatanetsatane pamlingo wagawo kumalepheretsa kupotoza ndikuchepetsa kufunikira kokonza zithunzi. Chifukwa chake, madokotala amatha kuwunika bwino odwala ndikuwazindikira popanda kugwiritsa ntchito njira zowonjezera.
