Zvikamu Zvakarurama ndizvo Kiyi Yekufananidza Mifananidzo Yemhando Yepamusoro

Nyanzvi dzezvehutano nevarwere vanovimba ne magnetic resonance imaging (MRI) uyeKuongororwa kweCTtekinoroji yekuongorora nyama dzakapfava nenhengo dzemuviri, kuona matambudziko akasiyana-siyana kubva kuzvirwere zvinokanganisa kusvika kumabundu nenzira isingakuvadzi. Muchina weMRI unoshandisa simba remagineti rine simba uye mafungu eredhiyo akagadzirwa nekombuta kugadzira mifananidzo inochinjika. Saka, kunaka kweMRI kunoenderana nekufanana kwesimba remagineti - kunyangwe kadiki diki kemagineti mukati meMRI scanner kunogona kukanganisa munda uye kuderedza kunaka kwemufananidzo weMRI.

Mashandiro anoita MRI padanho repamusoro

Michina yeMRI yatinoziva nhasi inoshanda pamusimboti we nuclear magnetic resonance (NMR). Zvikuru, mamorekuru ari mumuviri wemunhu ane hydrogen, uye nucleus yeatomu yehydrogen ine proton imwe chete inoshanda semagineti ine kuchamhembe nekuchamhembe kwepasi. Kana simba remagineti rikashandiswa, ma spins avo, hunhu hwezvikamu zve subatomic, anowirirana zvakaenzana. Murwere paanoiswa mukati meMRI scanner tube, ma spins emaproton ari mumamorekuru emuviri anofanana, ese akatarisana nedivi rimwe chete, zvakafanana nebhendi rinofamba richidzidzira panhandare yenhabvu.

Kunyange zvakadaro, kunyangwe musiyano mudiki kwazvo musimba remagineti unogona kukonzera kuti mapurotoni aenderane nenzira dzakasiyana, zvichireva kuti haazopindure nenzira imwechete kune chinokurudzira. Kusiyana uku kunogona kukanganisa maalgorithms ekuona. Muchokwadi, kuona uku kusina kurongeka, ruzha rwakanyanya rwechiratidzo, kana kuchinja-chinja kwesimba rechiratidzo kunogona kukonzera mifananidzo isina kujeka. Mufananidzo usina kunaka unogona kutungamira mukuongororwa kusina kururama uye, nekudaro, sarudzo dzisina kunaka dzekurapa.

Kusarudzwa kweZvinhu Zvine Chikamu Kwakakosha

Kuvapo kwezvikamu zvemagineti mukati meMRI scanner tunnel kunogona kukanganisa kufanana kwemunda, uye kunyange huwandu hudiki hwemagineti hunogona kukanganisa kunaka kwemufananidzo weMRI. Nekuda kweizvozvo, zvakakosha kuti vagadziri vezvishandiso zvekurapa vatsvage zvikamu, zvakaita sema capacitor akagadziriswa, ma trimmer capacitors, ma inductors, uye ma connectors, akavakwa nesimbi dzakachena kwazvo dzisina magineti anoyerwa.

Kutevedzera zvinodiwa izvi kunotanga nekutevera kwakasimba uye maitiro ekuyedza, pamwe nehwaro hwakasimba muhunyanzvi hwesainzi yezvinhu. Semuenzaniso, ma capacitor akawanda akagadzirwa ne nickel barrier finish kuchengetedza kugona kwekusvira; zvisinei, hunhu hwemagineti hwe nickel hunoita kuti capacitor isakodzere kushandiswa mumifananidzo. Saizvozvowo, brass yekutengeserana, chimwe chinhu chinowanzoshandiswa, hachina kukodzerawo zvinangwa izvi.

Kunyatsotarisa zvinhu zvakadzama padanho rechikamu kunodzivirira kukanganiswa uye kunoderedza kukosha kwekugadziriswa kwemufananidzo. Nekuda kweizvozvo, vanachiremba vanogona kuongorora nekuongorora varwere zvinobudirira pasina kuda mamwe maitiro ekurapa anokanganisa.
