Zigawo Zolondola Ndi Chinsinsi cha Kujambula Zithunzi Zapamwamba Kwambiri

Akatswiri azaumoyo ndi odwala amadalira magnetic resonance imaging (MRI) ndiKujambula kwa CTukadaulo wofufuza minofu ndi ziwalo zofewa m'thupi, kuzindikira mavuto osiyanasiyana kuyambira matenda osachiritsika mpaka zotupa mwanjira yosavulaza. Makina a MRI amagwiritsa ntchito mphamvu yamphamvu ya maginito ndi mafunde a wailesi opangidwa ndi kompyuta kuti apange zithunzi zodutsa m'magawo osiyanasiyana. Chifukwa chake, ubwino wa MRI umadalira kufanana kwa mphamvu ya maginito - ngakhale kachidutswa kakang'ono ka maginito mkati mwa MRI scanner kangasokoneze munda ndikuchepetsa ubwino wa chithunzi cha MRI.

Momwe MRI Imagwirira Ntchito Pamwamba Kwambiri

Makina a MRI omwe tikudziwa bwino masiku ano amagwira ntchito motsatira mfundo ya nuclear magnetic resonance (NMR). Makamaka, mamolekyu omwe ali mkati mwa thupi la munthu ali ndi haidrojeni, ndipo nucleus ya atomu ya haidrojeni imakhala ndi pulotoni imodzi yomwe imagwira ntchito ngati maginito yokhala ndi nsonga ya kumpoto ndi kumwera. Pamene mphamvu ya maginito ikugwiritsidwa ntchito, ma spin awo, omwe ndi tinthu tating'onoting'ono ta subatomic, amafanana mofanana. Wodwala akamayikidwa mkati mwa chubu chojambulira cha MRI, ma spin a ma protoni omwe ali m'mamolekyu a thupi amafanana, onse akuyang'ana mbali imodzi, mofanana ndi gulu loyenda lomwe likuchita masewera olimbitsa thupi pabwalo la mpira.

Komabe, ngakhale kusiyana kochepa kwambiri mu mphamvu ya maginito kungapangitse ma proton kugwirizana m'njira zosiyanasiyana, zomwe zikutanthauza kuti sangayankhe mofanana ndi cholimbikitsacho. Kusiyana kumeneku kungasokoneze ma algorithms ozindikira. Zoona zake n'zakuti, kuzindikira kosazolowereka kumeneku, phokoso lalikulu la chizindikiro, kapena kusinthasintha kwachisawawa kwa mphamvu ya chizindikiro kungayambitse zithunzi zosamveka bwino. Chithunzi chosakhala chabwino kwambiri chingayambitse matenda olakwika ndipo, chifukwa chake, zisankho zolakwika za chithandizo.

(Monga tonse tikudziwira, kujambula zithunzi kuyenera kuchitidwa kudzera mu chida chosiyanitsa zinthu, ndipo kuyenera kulowetsedwa m'thupi la wodwalayo kudzera mumajakisoni othamanga kwambirikomansosirinji ndi machubuLnkMed ndi kampani yopanga zinthu zomwe zimathandiza kwambiri popereka zinthu zosiyanitsa mitundu. Idapangidwa yokha.MRIkusiyanajekeseni, Jakisoni wa CT scanndijekeseni ya DSAzagawidwa m'zipatala m'maiko ambiri kuti zipereke chithandizo chamankhwala. Majekeseni athu ndi osalowa madzi, osinthasintha kwambiri, komanso osavuta kwa ogwira ntchito zachipatala kusuntha ndikugwira ntchito; amagwiritsa ntchito kulumikizana kwa Bluetooth, wogwiritsa ntchito safunika kuthera nthawi yambiri akuyika ndi kukhazikitsa; zida zosinthira zaulere ngati ntchito yogulitsa ikupezeka. LnkMed yadzipereka kupereka zinthu ndi ntchito zapamwamba kwambiri kwaradiology ndi kujambula zithunzi.

Kusankha Zinthu Zofunika Kwambiri Ndikofunikira

Kupezeka kwa zigawo zamaginito mkati mwa ngalande ya MRI scanner kumatha kusokoneza kufanana kwa malo, ndipo ngakhale kuchuluka kwa maginito pang'ono kungakhudze mtundu wa chithunzi cha MRI. Chifukwa chake, ndikofunikira kuti opanga zida zamankhwala afufuze zigawo, monga ma capacitor okhazikika, ma trimmer capacitor, ma inductor, ndi zolumikizira, zomwe zimapangidwa ndi zitsulo zoyera kwambiri zopanda maginito oyeretsedwa.

Kutsatira lamuloli kumayamba ndi njira zolondola komanso zoyesera, komanso maziko olimba muukadaulo wa sayansi ya zinthu. Mwachitsanzo, ma capacitor ambiri amapangidwa ndi nickel barrier finish kuti asunge kusinthasintha kwa soldering; komabe, mphamvu zamaginito za nickel zimapangitsa kuti capacitor ikhale yosayenera kugwiritsidwa ntchito pojambula zithunzi. Momwemonso, brass yogulitsa, chinthu china chomwe chimagwiritsidwa ntchito nthawi zambiri, sichilinso choyenera pazifukwa izi.

Kusamala kwambiri koteroko pamlingo wa zigawo kumaletsa kusokonekera ndipo kumachepetsa kufunika kokonza chithunzi. Chifukwa chake, madokotala amatha kufufuza bwino ndikuzindikira odwala popanda kufunikira njira zina zowononga.
