Magnetic Resonance fungidzira, anowanzo kutaurwa seMRI, is is is is is-isisive yekuongorora yekufungidzira maitiro akashandiswa zvakanyanya nehutano nyanzvi kuti vaone zvivakwa zvemukati. MRI inoshandisa minda yakasimba yemagetsi uye radio mafungu kuti ugadzire mifananidzo yakadzama yemitezo yemuviri, matishu, uye mapfupa.
Pamusoro peMRI MBRI, mubvunzo unowanzomuka mupfungwa dzevanhu ndosaka kri kamuri inofanirwa kuve yemhangura-yakarongedzwa? Mhinduro yemubvunzo uyu iri mune nheyo dzemagetsi.
Kana MRI Machine ichishandurwa, iyo inogadzira iyo ine simba yemagineti inogona kukanganisa zvishandiso zvemagetsi zvemagetsi uye masisitimu. Kuvapo kwemagineti emagineti kunogona kukanganisa mamwe midziyo yemagetsi senge makomputa, mafoni, uye midziyo yokurapa, uye inogona kukanganisa maitiro evanokambaira pacemaker.
Kuchengetedza izvi zvishandiso uye chengetedza kutendeka kwemidziyo yekufungidzira, iyo Mri Chammy yakarongedzwa neCopper foil, izvo zvinoitwa sechinhu chipingamupinyi kumagineti. Copper inogadzirisa zvakanyanya, zvinoreva kuti inobata uye inoparadzira simba remagetsi uye rinoshanda pakuratidza kana kudzivirira mapoka emagineti.
A Copper Clining pamwe nekuwedzera foam uye plywood inogadzira caraday cage yakatenderedza muMRI muchina. Iyo farday cage ndeye yakavharirwa yakagadzirirwa kuvharira minda yemagetsi uye kudzivirira kupindira nemidziyo yemagetsi. Iyo cage inoshanda nekuparadzira bhadharo remagetsi zvakaringana pamusoro pechikamu, nekumanikidza kusarerekera chero chero nzira yekunze yemagetsi.
Copper foilhaingoshandiswi chete nekuchengetedza, asi zvakare nekugadzirisa. MRI Machina anoda mafungu akakwira kuti apfuurwe nemhirizhonga ayo anogadzira munda wemagineti. Aya mafungu anokwanisa kukonzeresa kuvakwa kwemagetsi magetsi anogona kukuvadza michina uye kunyange kuve nengozi kune varwere. Copper foil inoiswa pamadziro uye pasi peMRI Chamudza kupa nzira yeiyi mhosva yekuparadza pasi.
Mukuwedzera, kushandisa mhangura sezvo zvinhu zvekuvhura zvinopa zvakanakira nzira dzetsika dzechinyakare. Kutungamira kwakaipa, mhangura kwakanyanya uye kunogona kuve kwakagadzirwa nyore nyore mumhando dzakasiyana siyana uye saizi kusangana nezvinodiwa zveMRI Kamuri yeMRI. Izvo zvakare zvakatonyanya kukosha-zvinobudirira uye zvakatipoteredza hushamwari pane kutungamira.
Mukupedzisa, makamuri emakamuri akanyorwa nemhangura foil yechikonzero chakanaka. Iyo yekuchengetera nzvimbo yeCopper foilDzivirira kufungidzira zvishandiso kubva pakunze electromagnic kukanganiswazve apo kuona murwere uye tsvimbo yekuchengetedza. Iyo mhangura yakavharwa pamwe nezvimwe zvinhu kuti iite mafuro emakona ayo ane magineti emagineti anogadzirwa nemuchina weMRI muchina nenzira yakachengeteka uye inodzorwa. Copper ndiyo yakanakisa conductor yemagetsi, uye kushandisaCopper foilinovimbisa kuti mubatiri wemakore akanyatsogadziriswa. Nekuda kweizvozvo, kushandiswa kwemhangura foil muMRI kuvharidzira kwave kuita tsika dzakasiyana muindasitiri yezvekurapa, uye nechikonzero chakanaka.
