Kusunungura mabhoti mune magnetic field ye 1.5 Tesla uchishandisa simbi yesimbi haisi pfungwa yakanaka. Munda, semuvengi asingaoneki, anoramba achiedza kubvuta chiridzwa kubva pamaoko, achichifambisa pamwe chete nemitsetse yaro yesimba uye atungamirire iyo iri pedyo sezvinobvira kune ma electrons anomhanya mudenderedzwa rakavharwa kubva kune superconductor. Nekudaro, kana iwe uchida chaizvo kukunda acidified komisheni kubva makore mazhinji apfuura, hapana yakawanda sarudzo. Ndakagara pasi pakombiyuta uye ndaigara ndichiongorora nhau. "Masayendisiti eRussia akavandudza MRI ne2 nguva!" - verenga musoro wenyaya unofungidzira.
Rinenge gore rapfuura, isu uye akanzwisisa chinangwa chebasa rake. Ndinokurudzira zvakasimba kuti uvandudze ndangariro yako yechinhu ichocho usati waverenga chinyorwa ichi.
Nezvikonzero zvakasiyana-siyana, kusanganisira nhoroondo, muRussia nhasi kugadzirwa kwemidziyo yakaoma yakadai seyakakwirira-munda magineti resonance imaging scanners. Nekudaro, kana uchigara muguta rakakura, unogona kuwana nyore makiriniki anopa rudzi urwu rwesevhisi. Panguva imwecheteyo, boka reMRI scanners rinowanzomiririrwa nemidziyo yakashandiswa, yakambotengeswa kubva kuU.SA neEurope, uye kana iwe ukangoerekana washanyira kiriniki neMRI, usanyengerwa nekuonekwa kwakanaka kwechigadzirwa - inogona kunge iri mumakore gumi echipiri. Somugumisiro, michina yakadaro dzimwe nguva inoputsika, uye kwenguva yakareba ndaiva mumwe wevaya vakadzorera tomographs dzakaputsika kushanda, kuitira kuti varwere varambe vachiongororwa, uye varidzi vanogona kuita purofiti.
Kutozosvikira rimwe zuva rakanaka, panguva yekuzorora pakati pevaraidzo ine ngozi ine simba remagineti yakakura, ndakaona chinyorwa chinonakidza munhau: "Masayendisiti eRussia pamwe chete nevamwe vechiDutch. kushandisa metamaterials." Hazvina maturo kutaura, chokwadi chokuti Russia iri kuita tsvakurudzo pamusoro pemichina, kugadzirwa kwayo kusati kwamboitwa, yakaratidza kwandiri, yakakakavadzana zvikuru. Ndakasarudza kuti iyi yaingova imwe yerutsigiro yezvipo, yakaderedzwa neasinganzwisisike buzzwords yesainzi se "nanotechnology" iyo munhu wese aive atodyiswa nayo. Kutsvaga ruzivo pamusoro penyaya yebasa remasayendisiti epamba ane MRI uye metamaterials akanditungamirira kune imwe nyaya ine tsananguro yekuedza kuri nyore kwandinogona kudzokorora nyore nyore, sezvo muchina weMRI unogara uri pedyo.
Mufananidzo kubva , yakatsaurirwa kusimbisa chiratidzo cheMRI uchishandisa iyo inonzi "metamaterial". Mukiriniki yakajairwa 1.5 - Thermal apparatus, panzvimbo yemurwere, metamaterial inotakurwa, muchimiro chebheseni remvura, mukati mayo mawaya akaenzana ehurefu hwakati anowanikwa. Pawaya pane chinhu chekudzidza - hove (isina-kurarama). Mifananidzo iri kurudyi mifananidzo yeMRI yehove, ine mepu yeruvara yakasimudzwa inoratidza kusimba kwechiratidzo chehydrogen nuclei. Zvinogona kuonekwa kuti kana hove ichivata pawaya, chiratidzo chiri nani kupfuura pasina. Nguva yekuongorora yakafanana mune zvese zviri zviviri, izvo zvinoratidza kuti kutarisisa kunoshanda kunowedzera. Nyaya yacho yakanyatsobatanidza
formula
kuverenga urefu hwetambo zvichienderana nehuwandu hwekushanda kwetomograph, yandakashandisa. Ndakagadzira metamaterial yangu kubva kune cuvette uye tambo dzemhangura waya, dzakashongedzerwa ne3D yakadhindwa epurasitiki yekusimbisa:
Metamatiari yangu yekutanga. Pakarepo mushure mekugadzirwa kwakaiswa mu1 Tesla tomograph. Orange yaiita sechinhu chinotariswa.
Nekudaro, pachinzvimbo chekusimudzira chiratidzo chakavimbiswa, ndakagamuchira boka rezvigadzirwa zvakashatisa zvachose mufananidzo! Hasha dzangu hadzina magumo! Mushure mokunge ndapedza nyaya yacho, ndakanyora tsamba kune vanyori vezvinyorwa, izvo zvinoreva zvinogona kuderedzwa kumubvunzo wekuti "Chii ...?"
Vanyori vakandipindura nekukurumidza. Vakashamiswa zvikuru kuti mumwe munhu akanga achiedza kudzokorora kuedza kwavo. Pakutanga vakaedza kwenguva yakareba kunditsanangurira kuti metamatadium inoshanda sei, vachishandisa mazwi ekuti "Fabry-Perot resonances", "intrinsic modes", uye marudzi ese eredhiyo frequency minda muvhoriyamu. Ipapo, sezviri pachena vachiziva kuti ndakanga ndisingatongonzwisisi zvavakanga vachitaura nezvazvo, vakasarudza kundikoka kuti ndivashanyire kuitira kuti ndigogona kutarira kufambira mberi kwavo kurarama uye kuva nechokwadi chokuti kuchiri kushanda. Ndakakanda simbi yangu yaifarira solder muhomwe yangu ndokuenda kuSt.
Ndakagamuchirwa nemufaro panzvimbo, uye kamwe kamwe, vakandipa basa, sezvo vakafadzwa negoronga rangu newaya uye vaida munhu wokusika matsva. Mukudzoka, vakavimbisa kutsanangura zvakadzama zvose zvinondifadza uye kutora kosi yekudzidzira radiophysics neMRI, iyo, nemhanza, yakatanga gore iroro chairo. Nyota yangu yeruzivo yakakunda, uyezve, gore rose, ndakadzidza, ndakaita mapurojekiti uye ndikashanda, zvishoma nezvishoma ndichidzidza zvinhu zvitsva zvakawanda nezvenhoroondo yemagnetic resonance, pamwe chete nemamiriro esainzi yemazuva ano munzvimbo ino, yandichaita. share pano.
Nzira yekuvandudzwa kweMRI, uye yakadzidza munyaya dzesayenzi dzakataurwa, inobva pane izvo zvinonzi "metamataries". Metamaterials, kufanana nezvimwe zvakawanda zvakawanwa, zvinokwereta chitarisiko chavo kune zvisingatarisirwi mhinduro dzakawanikwa pahwaro hwekutsvagisa kwedzidziso. Musayendisiti weSoviet, Viktor Veselago, muna 1967, achishanda pamuenzaniso wezvinyorwa, akakurudzira kuvapo kwezvinhu zvine negative refractive index. Sezvaunotonzwisisa, isu tiri kutaura nezve optics, uye kukosha kweiyo coefficient, zvishoma kutaura, zvinoreva kuti chiedza chakawanda sei chichachinja nzira yaro kana ichipfuura nemuganho pakati pemidhiya yakasiyana, semuenzaniso mhepo nemvura. Unogona kuzvionera wega kuti izvi zvinoitika chaizvo:
Chiyedzo chiri nyore kushandisa laser pointer uye aquarium kuratidza kudzoreredza kwechiedza.
Chinhu chinonakidza chinogona kudzidzwa kubva mukuyedza kwakadai ndechekuti danda harigone kudzokororwa munzira imwechete kubva payakawira pane iyo interface, zvisinei nekuti muyedzeri anoedza zvakadii. Kuedza uku kwakaitwa nezvinhu zvese zvinongoitika, asi danda rakasindimara rakadzorwa munzira imwe chete. Masvomhu, izvi zvinoreva kuti iyo refractive index, pamwe nehuwandu hwayo, dielectric uye magineti permeability, yakanaka, uye haina kumbobvira yaonekwa neimwe nzira. Kusvikira V. Veselago akasarudza kudzidza nyaya iyi uye akaratidza kuti theoretically hapana chikonzero chimwe chete nei refractive index haigoni kuva yakaipa.
Mufananidzo kubva kuWiki unoratidza mutsauko pakati pechakanaka uye chisina kunaka index media. Sezvatinoona, chiedza chinozvibata zvachose, chichienzaniswa nechiitiko chedu chemazuva ose.
V. Veselago akaedza kwenguva yakareba kuti awane uchapupu hwekuvapo kwezvinhu zvine index yakaipa refractive, asi kutsvaga hakuna kubudirira, uye basa rake rakanga risina kukanganwika. Kwaingove pakutanga kwezana ramakore rakatevera apo zvimiro zvakaumbwa zvakasikwa zvakaona zvakatsanangurwa zvivakwa, asi kwete mumaziso, asi mune yakaderera microwave frequency renji. Yakanga iri nguva yekuchinja, sezvo mukana chaiwo wekuvapo kwezvinhu zvakadaro wakazarura tarisiro itsva. Somuenzaniso - kugadzira , inokwanisa kukudza zvinhu kunyange zviduku kudarika masaisai echiedza. Kana - absolute camouflage invisibility coverings, kurota kwevose vashandi vemauto. Kugadziriswa kukuru kwakaitwa kune dzidziso yekufunga nezve data nyowani. Chinokosha chekubudirira kwaiva kushandiswa kwemaitiro akarongedzerwa ezvinyorwa zvinonzwika - metaatoms, hukuru hwayo huduku zvikuru kupfuura urefu hwemwaranzi iyo yavanosangana nayo. Chimiro chakarongedzerwa chemeta-atomu chinhu chakagadzirwa chakaumbwa chinonzi metamaterial.
Kuitwa kunoshanda kwemetamaterials kunyangwe nhasi kwakaoma tekinoroji, sezvo saizi yezvimedu zvinonzwika zvichifanira kuenzaniswa neisingasviki wevelength yemagetsi emagetsi. Kune iyo optical range (apo wavelength iri nanometers), matekinoroji akadaro ari kumberi kwekufambira mberi. Naizvozvo, hazvishamise kuti vamiriri vekutanga veiyo metamaterials pfungwa vakasikirwa kurebesa mafungu emagetsi emagetsi kubva kuredhiyo (iyo ine hurefu hunozivikanwa kubva mm kusvika m). Chinhu chikuru uye panguva imwechete iyo kusakosha kwechero metamaterial mhedzisiro ye resonant yemhando yezvinhu zvayo zvinoumba. Metamaterial inogona kuratidza zvinhu zvayo zvinoshamisa pane mamwe ma frequency.
Mafambiro mashoma.Naizvozvo, semuenzaniso, nguva inotevera paunoona chimwe chinhu senge super-sound jammer yakavakirwa pametamaterials, bvunza kuti ndeapi frequency renji inojamba.
Mienzaniso yakajairika yemametamaterials inobvumira kudyidzana nemagetsi emagetsi mafungu. Conductor zvimiro hazvisi chinhu kunze kwediki resonators, LC maseketi akaumbwa nenzvimbo yepasi yemakondakita.
Nguva shoma yapfuura kubva pakabuda pfungwa yemetamaterials uye maitiro avo ekutanga, uye vanhu vakafunga kuti vangashandisa sei muMRI. Chinhu chikuru chakashata chemetamaterials ndechekuti iyo yakatetepa yekushanda siyana haisi dambudziko kune MRI, uko maitiro ese anoitika painoda kufanana nyukireya magineti resonance frequency, iri muredhiyo. Pano iwe unogona kugadzira meta-atomu nemaoko ako uye pakarepo ona zvinoitika mumifananidzo. Chimwe chezvinhu zvekutanga izvo vatsvakurudzi vakashandisa muMRI vachishandisa metamaterials vaiva superlenses uye endoscopes.
Kurutivi rworuboshwe pasi petsamba a) pane superlens inoratidzwa, inosanganisira matatu-dimensional array yemaresonator pamabhodhi edunhu akadhindwa. Imwe neimwe resonator ndeye yakavhurika simbi mhete ine soldered capacitor, ichigadzira LC dunhu rakagadzirirwa kuMRI frequency. Pazasi pane muenzaniso wekuisa iyi metamaterial chimiro pakati pemakumbo emurwere ari kuita tomography uye, maererano, inoguma mifananidzo. Kana iwe usati wambozvidza zano rekuverenga chinyorwa changu chekare paMRI, saka iwe unotoziva kuti kuti uwane mufananidzo wechero chikamu chemuviri wemurwere, zvakakosha kuunganidza isina simba, nekukurumidza kuora masaini enyukireya uchishandisa iri pedyo. antenna - coil.
Iyo metamaterial super lens inobvumidza iwe kuti uwedzere huwandu hwechiito cheyakajairika coil. Somuenzaniso, fungidzira makumbo ose omurwere panguva imwe chete pane rimwe chete. Nhau dzakaipa ndedzekuti nzvimbo yema superlens inofanira kusarudzwa neimwe nzira kuti iite zvakanakisa, uye ma superlens pachawo anodhura kugadzira. Kana iwe uchiri kunzwisisa kuti sei lenzi iyi ichinzi super-prefix, saka fungidzira saizi yayo kubva pamufananidzo, uye wobva waziva kuti inoshanda nehurefu hwemamita mashanu!
Tsamba b) inoratidza dhizaini ye endoscope. Chaizvoizvo, iyo MRI endoscope imhando yewaya dzakafanana dzinoita senge waveguide. Inokubvumira kuparadzanisa nzvimbo kubva iyo coil inogamuchira chiratidzo kubva kune nuclei uye coil pachayo nechinhambwe - kusvika padanho rekuti antenna yekugamuchira inogona kuwanikwa zvachose kunze kweiyo cryostat ye tomograph, kure neanogara magineti. munda. Iwo epazasi mapikicha etabhu b) inoratidza mifananidzo yakawanikwa kune yakakosha-izere mvura mudziyo - phantom. Musiyano uripo pakati pavo ndewekuti mifananidzo yakanyorwa kuti "endoscope" yakawanikwa apo coil yaive iri chinhambwe chakanaka kubva kune phantom, uko pasina endoscope masaini kubva nuclei aisazokwanisa kuona zvachose.
Kana tikataura nezveimwe yenzvimbo dzinovimbisa dzekushandiswa kwemetamaterials muMRI, uye iri padyo nekushandiswa kwayo kunoshanda (iyo yandakazopinda mukati) ndiko kusikwa kwemakoiri asina waya. Zvakakodzera kujekesa kuti hatisi kutaura nezveBluetooth kana imwe isina waya yekufambisa data tekinoroji pano. "Wireless" mune iyi kesi inoreva kuvapo kweiyo inductive kana capacitive coupling yezvimiro zviviri zvinonzwika - transceiver antenna, pamwe nemetamaterial. Muchiitiko chinotaridzika seizvi:
Kuruboshwe kunoratidzwa kuti chirongwa cheMRI chinowanzoitwa sei: murwere akarara mukati me cryostat munzvimbo yeuniform static magnetic field. Antenna hombe inonzi "shiri cage" inoiswa mutomograph tunnel. Antenna yeiyi gadziriso inobvumidza iwe kutenderedza vector yeredhiyo frequency magineti ine precession frequency yehydrogen nuclei (yemichina yekiriniki iyi inowanzobva pa40 kusvika 120 MHz zvichienderana nehukuru hweiyo static magnetic field kubva pa1T kusvika 3T, zvichitevedzana), zvichiita kuti vatore simba uye vozobudisa simba mukupindura . Chiratidzo chekupindura kubva kumacores chakanyanya kusimba uye panguva yainosvika kune maconductor e antenna hombe, inotodzima. Nekuda kwechikonzero ichi, MRI inoshandisa macoil emuno akaganhurwa zvakanyanya kuti agamuchire masaini. Mufananidzo uri pakati, semuenzaniso, unoratidza mamiriro ekutarisa ibvi. Uchishandisa metamaterials, zvinokwanisika kuita resonator iyo inozove inductively yakabatanidzwa kune shiri yeshiri. Zvakakwana kuisa chinhu chakadaro pedyo nenzvimbo inodiwa yemuviri wemurwere uye chiratidzo kubva ipapo hachizogamuchirwe zvakanyanya kupfuura nekoiri yemuno! Kana iyo pfungwa ikashandiswa zvinobudirira, varwere havachafanirwa kusungirirwa muwaya, uye chirongwa cheMRI chekuongorora chinova chakanyanya kugadzikana.
Iyi ndiyo chaiyo mhando yechinhu chandakaedza kugadzira pakutanga, nekuzadza waya nemvura uye kuedza kuongorora orenji. Waya dzakanyudzwa mumvura kubva pamufananidzo wekutanga muchinyorwa ichi hachisi chinhu chinopfuura meta-atomu, imwe neimwe inomiririra hafu-wave dipole - imwe yeanonyanya kufarirwa antenna dhizaini, inozivikanwa kune wese radio amateur.
Vanonyudzwa mumvura kwete kuitira kuti varege kubata moto muMRI (kunyangwe nechinangwa ichi zvakare)), asi kuti, nekuda kweiyo yakakwira dielectric nguva yemvura, vaderedze kureba kwavo nechiyero chakaenzana neskweya. mudzi we dielectric constant yemvura.
Iyi chip yakagara ichishandiswa mumaredhiyo ekugamuchira, waya inomonereka pachidimbu cheferrite - iyo inonzi. ferrite antenna. Ferrite chete ine yakakwirira magineti permeability, uye kwete dielectric imwe, iyo, zvisinei, inoshanda nenzira imwechete uye inobvumira resonant zviyero zveantenna kuderedzwa zvinoenderana. Nehurombo, haugone kuisa ferrite muMRI, nekuti ... ine magineti. Mvura inzira yakachipa uye inosvikika.
Zviripachena kuti kuverenga zvinhu zvese izvi, iwe unofanirwa kuvaka akaomesesa masvomhu mamodheru anofunga hukama pakati pezvinhu zvinonzwika, maparamendi ezvakatipoteredza uye masosi emwaranzi ... kana iwe unogona kutora mukana wemichero yekufambira mberi uye software yenhamba yemagetsi modelling, iyo kunyange mwana wechikoro anogona kunzwisisa zviri nyore (mienzaniso inoshamisa - CST, HFSS). Iyo software inokubvumira kuti ugadzire 3D mhando dze resonators, antennas, matunhu emagetsi, kuwedzera vanhu kwavari - hongu, muchokwadi, chero chinhu, mubvunzo chete ndeye fungidziro yako uye iripo komputa simba. Mhando dzakavakwa dzakakamurwa kuita grids, pane nodes iyo inozivikanwa kwazvo Maxwell equations inogadziriswa.
Heino, semuenzaniso, kuenzanisa kweredhiyo frequency magineti mukati meiyo yakambotaurwa yeshiri cage antenna:
Zvinobva zvanyatsojeka kuti munda unotenderera sei. Mamiriro ari kuruboshwe anoratidzwa kana pane bhokisi remvura mukati meantenna, uye kurudyi - kana bhokisi rimwechete riri pane resonator yakagadzirwa netambo dzeresonant kureba. Iwe unogona kuona kuti iyo magnetic field inowedzerwa sei zvakanyanya newaya. Mushure mekuziva CST uye nekugadzirisa dhizaini yangu ipapo, ndakagadzira zvakare metamaterial, iyo yakanyatsoita kuti zvikwanise kukwidziridza chiratidzo mune yakajairwa kiriniki 1.5T MRI tomograph. Rakanga richiri bhokisi (kunyangwe rakanyanya kunaka, rakagadzirwa neplexiglass), rakazara nemvura uye netambo dzewaya. Panguva ino, chimiro chakagadziridzwa maererano nemamiriro ekugadzirisa, kureva: kusarudzwa kwehurefu hwetambo, nzvimbo yavo, uye huwandu hwemvura. Hezvino zvakaitika nematomatisi:
Yekutanga scan yemadomasi yakaitwa neantenna hombe. Mhedzisiro yaingova ruzha rwaisanyatsooneka. Kechipiri ndakaisa muchero patsva yakabikwa resonance structure. Ini handina kuvaka mepu dzine mavara kana chero chinhu chakadaro, sezvo mhedzisiro yacho iri pachena. Nokudaro, kubva pane zvakaitika kwandiri, kunyange zvazvo ndakapedza nguva yakawanda, ndakaratidza kuti pfungwa yacho inoshanda.
Zvakajeka zvauri kufunga - maranjisi, matomatisi - zvese hazvina kunaka, miyedzo yevanhu iripi?
Vaiva zvechokwadi :
Ruoko rwemunhu anozvipira ari MRI akarara pabhokisi rimwe chete. Mvura chaiyo iri mubhokisi, sezvo ine hydrogen, inoonekwawo zvakajeka. Chiratidzo chinokwidziridzwa munzvimbo yechanza yakarara pane resonator, nepo dzimwe nhengo dzese dzemuviri dzisingaonekwe. Zviri pachena kuti maitiro akafanana, uye pamwe zvirinani, anogona kuwanikwa uchishandisa akajairwa kiriniki coils. Asi chokwadi chekuti iwe unogona kuita zvinhu zvakadaro nekungosanganisa nzvimbo nemvura newaya, kuzvisanganisa nenzira kwayo, zvinoshamisa. Zvakatonyanya kushamisa, ruzivo pamusoro peizvi runogona kuwanikwa kuburikidza nekudzidza kwezviitiko zvinoita sezvisina hukama, sekupenya kwechiedza.
Kune avo vasati vanetaParizvino, kugadzirwa kwebhokisi remvura kwakatovandudzwa. Ikozvino ingori bhati rakadhindwa redunhu bhodhi iro rinokutendera iwe kuti utore nzvimbo yemagineti yekunze hombe antenna padhuze newe. Uyezve, nzvimbo yayo yekushanda yakakura kupfuura iyo yekare dhizaini:
Marabhoni ane mavara anoratidza simba remagineti pamusoro pechivakwa kana richinakidzwa nekunze kwekunze kwemasaisai emagetsi. Iyo flat chimiro ndeye yakajairika tambo yekufambisa inozivikanwa muredhiyo engineering, asi inogona zvakare kutariswa semetamati yeMRI. Iyi "wireless coil" inogona kutokwikwidza nemakoiri akajairwa maererano nekufanana kwemunda wakagadzirwa pane imwe kudzika muchinhu chakaongororwa:
Iwo animation inoratidza akaturikidzana-ne-layer mepu yemavara echiratidzo mukati mebhokisi remvura muMRI. Ruvara runoratidza kusimba kwezviratidzo kubva kuhydrogen nuclei. Mukona yekumusoro kuruboshwe, chikamu cheyakajairika back scanning coil chinoshandiswa sechinogamuchira. Iyo yezasi yekona yekuruboshwe ndiyo iyo bhokisi rinoiswa pane resonator muchimiro chedhidhi redunhu bhodhi. Pazasi kurudyi - chiratidzo chinogamuchirwa neantenna hombe yakavakirwa mumugero wetomograph. Ndakafananidza kufananidzwa kwechiratidzo munzvimbo inotsanangurwa nerectangle. Pane kumwe kukwira, metamaterial inoita zvirinani pane coil maererano nekufanana kwechiratidzo. Nekuda kwezvinangwa zvekiriniki, izvi zvinogona kunge zvisiri zvakakosha zvakanyanya kubudirira, asi kana zvasvika kune yesainzi MRI yekumisikidza uko makonzo anoongororwa, inogona kubatsira kuwana kuwedzera kwechiratidzo uye kuderera kwesimba rinodiwa rekunakidza redhiyo pulses.
Nezve "kunatsiridzwa ne2 nguva" pakutanga kwechinyorwa - hongu, ichi ndicho chimwe chibereko cherudo rusingadzoreki rwevatapi venhau kune masayendisiti, zvisinei, hazvina kunaka zvakare kutaura kuti iyi itsvakurudzo isina chinhu, inotsigirwa nekufarira nyaya iyi mumapoka esainzi pasi rose. Sezvineiwo, basa riri kuitwawo muno muRussia, kunyangwe zvichibva paruzivo rwangu pachangu, izvi ndizvo zvisingawanzo. Pachine matambudziko akawanda asina kugadziriswa ane chokuita nekushandiswa kwemetamaterials muMRI. Pamusoro penzvimbo yemagineti kuti uwane mufananidzo wakanaka, usakanganwa nezve minda yemagetsi inotungamira mukudziya kwematishu, pamwe nekutorwa kweradiofrequency field energy nematishu evarwere vari kuongororwa. Kune zvinhu izvi, mukushandiswa kwekiriniki, panofanirwa kuve nekutonga kwakakosha, izvo zvinova zvakanyanya kuoma kana uchishandisa munda-localizing resonators. Parizvino, mametaterials eMRI anoramba ari mukati mechikamu chekutsvakurudza kwesayenzi, asi zvigumisiro zvakawanikwa zvatova zvinonakidza uye zvichida mune ramangwana, kuvonga kwavari, maitiro eMRI achachinja kuti ave nani, achikurumidza uye akachengeteka.
