Iingcali zempilo kunye nezigulane zixhomekeke kwi-imaging resonance magnetic (MRI) kunyeCT scanitekhnoloji yokuhlalutya izicubu ezithambileyo kunye namalungu emzimbeni, ukufumanisa uluhlu lwemiba ukusuka kwizifo eziwohlokayo ukuya kumathumba ngendlela engeyiyo. Umatshini we-MRI usebenzisa i-magnetic field enamandla kunye namaza erediyo enziwe ngekhompyutha ukuvelisa imifanekiso enqamlezileyo. Ngoko ke, umgangatho we-MRI uxhomekeke ekufaniseni umbane wamagnetic - nokuba umkhondo omncinci we-magnetism ngaphakathi kwe-MRI scanner unokuphazamisa intsimi kunye nokunciphisa umgangatho womfanekiso we-MRI.
Indlela iMRI esebenza ngayo kwiNqanaba eliPhezulu
Oomatshini be-MRI esibaziyo namhlanje basebenza kumgaqo-siseko we-nuclear magnetic resonance (NMR). Ngokukodwa, iimolekyuli ezingaphakathi emzimbeni womntu ziqulethe i-hydrogen, kwaye i-nucleus ye-athomu ye-hydrogen ineproton enye esebenza njengemagnethi enepoleni engasentla nasezantsi. Xa intsimi yamagnetic isetyenziswa, i-spins yabo, ipropathi yamasuntswana e-subatomic, ihambelana ngokufanayo. Njengoko isigulana sibekwe ngaphakathi kwityhubhu yesikena se-MRI, ii-spins zeeprotons ezikwimolekyuli zomzimba zilungelelaniswa, zonke zijonge kwicala elinye, ngokufana nebhendi ejikelezayo eziqhelanisa nebala lebhola.
Nangona kunjalo, nolona tshintsho luncinci kwintsimi yamagnetic lunokubangela ukuba iiprotons zihambelane ngeendlela ezahlukeneyo, oku kuthetha ukuba abayi kuphendula ngendlela efanayo kwi-stimulus. Ezi zintlukwano zinokubhidanisa i-algorithms yokufumanisa. Ngokwenyani, oku kufunyaniswa kungaqhelekanga, ingxolo yomqondiso egqithisileyo, okanye ukuguquguquka okungacwangciswanga kobunzulu bomqondiso kunokukhokelela kwimifanekiso enqabileyo. Umfanekiso okumgangatho ophantsi unokukhokelela kuxilongo olungachanekanga kwaye, ngenxa yoko, izigqibo zonyango ezingalunganga.
(Njengoko sonke sisazi, ukucinga kufuneka kugqitywe nge-arhente ephakathi, kwaye kufuneka ifakwe kumzimba wesigulanaii-injection zoxinzelelo oluphezulukunye neisirinji kunye nemibhobho. I-LnkMed ngumvelisi osebenza ngokukodwa ekuncedeni ukuhanjiswa kwee-agent ezichaseneyo. Iphuhliswe ngokuzimeleyoI-MRIumahlukoisitofu, CT scan scankwayeIsitofu seDSAziye zasasazwa kwizibhedlele kumazwe amaninzi ukubonelela ngeenkonzo zonyango. Izitofu zethu azinamanzi, ziguquguquka kakhulu, kwaye zilungele abasebenzi bezonyango ukuba bahambe kwaye basebenze; basebenzisa unxibelelwano lweBluetooth, umqhubi akafuni ukuchitha ixesha elininzi ekumiseni nasekusetheni; iindawo ezitshintshiweyo zasimahla ukuba inkonzo yasemva kokuthengisa iyafumaneka. I-LnkMed izibophelele ekuboneleleni ngeemveliso neenkonzo ezikumgangatho ophezului-radiology kunye ne-imaging.

UKhetho Lwezinto eziphathekayo lubalulekile
Ubukho bamacandelo omagnetic ngaphakathi kwetonela yesikena se-MRI bunakho ukuphazamisa ukufana kwebala, kwaye nelona nani lincinci lemagnethi linokuchaphazela umgangatho womfanekiso weMRI. Ngenxa yoko, kubalulekile ukuba abavelisi bezixhobo zonyango bafune izinto ezinje ngee-capacitors ezimiselweyo, ii-trimmer capacitors, ii-inductors, kunye nezihlanganisi, ezakhiwe ngeentsimbi ezicoceke kakhulu ezingenawo nawuphi na umazibuthe onokulinganiswa.
Ukubambelela kule mfuno kuqala ngokulandelelwa okungqongqo kunye neenkqubo zovavanyo, kunye nesiseko esiluqilima kubuchwephesha besayensi yezixhobo. Ngokomzekelo, ii-capacitors ezininzi zenziwe nge-nickel barrier finish ukuze kugcinwe ukuthengiswa; nangona kunjalo, iipropathi zemagneti zenickel zinika i-capacitor engafanelekanga ukusetyenziswa kwizicelo zokucinga. Ngokunjalo, ubhedu lwentengiso, enye imathiriyeli esetyenziswa rhoqo, nayo ayizifanelanga ezi njongo.
Ukuqwalaselwa okucokisekileyo okunjalo kwiinkcukacha kwinqanaba lecandelo kuthintela ukuphazamiseka kwaye kunciphise imfuneko yokulungiswa komfanekiso. Ngenxa yoko, oogqirha banokuvavanya ngokufanelekileyo kwaye baxilonge izigulana ngaphandle kokufuna iinkqubo ezihlaselayo.
