Ochwepheshe bezempilo kanye neziguli bancike ku-imaging resonance magnetic (MRI) kanyeCT scanubuchwepheshe bokuhlaziya izicubu ezithambile nezitho zomzimba emzimbeni, ukuthola uchungechunge lwezinkinga kusukela ezifweni eziwohlokayo kuye kumathumba ngendlela engahlaseli. Umshini we-MRI usebenzisa inkambu kazibuthe enamandla namaza omsakazo akhiqizwa ikhompuyutha ukuze ukhiqize izithombe ezihlukene. Ngakho-ke, ikhwalithi ye-MRI incike ekufaneni kwendawo kazibuthe - ngisho nomkhondo omncane wamagnetism ngaphakathi kwesithwebuli se-MRI ungaphazamisa insimu futhi unciphise ikhwalithi yesithombe se-MRI.
Indlela I-MRI Esebenza Ngayo Ezingeni Eliphezulu
Imishini ye-MRI esiyijwayele namuhla isebenza ngomgomo we-nuclear magnetic resonance (NMR). Ngokuqondile, ama-molecule angaphakathi komzimba womuntu aqukethe i-hydrogen, futhi i-nucleus ye-athomu ye-hydrogen iqukethe iphrothoni eyodwa esebenza njengozibuthe ene-pole esenyakatho naseningizimu. Lapho kusetshenziswa inkambu kazibuthe, ama-spins awo, okuyisakhiwo sezinhlayiya ze-subatomic, aqondana ngokufanayo. Njengoba isiguli sibekwe ngaphakathi kweshubhu lesikena se-MRI, ama-spins ama-proton kuma-molecule omzimba aqondana, wonke abheke ohlangothini olufanayo, njengebhande elimashayo elizilolongela enkundleni yebhola.
Noma kunjalo, ngisho nokuhluka okuncane kakhulu endaweni kazibuthe kungabangela ukuba ama-proton ahambisane ngezindlela ezahlukene, okusho ukuthi ngeke aphendule ngendlela efanayo ekuvuseleleni. Lokhu kungafani kungadida ama-algorithms okutholwa. Eqinisweni, lokhu kutholwa okungajwayelekile, umsindo wesignali owedlulele, noma ukushintshashintsha okungahleliwe kokuqina kwesignali kungaholela ezithombeni eziluhlaza. Isithombe sekhwalithi ephansi singase siholele ekuxilongweni okungalungile futhi, ngenxa yalokho, izinqumo zokwelashwa ezingaqondile.
(Njengoba sazi sonke, ukuthwebula kudinga ukugcwaliswa kusetshenziswa i-medium -contrast agent, futhi kudinga ukufakwa emzimbeni wesiguli ngokusebenzisaama-injection aphezulukanye neisipetu namashubhu. I-LnkMed ngumkhiqizi osebenza ngokukhethekile ekusizeni ukulethwa kwama-ejenti wokuqhathanisa. Yakhe ngokuzimelaI-MRIqhathanisaumjovo, I-CT scan injectorfuthiI-DSA injectorziye zasatshalaliswa ezibhedlela emazweni amaningi ukuze zinikeze usizo lwezokwelashwa. Ama-injection ethu awangeni manzi, aguquguquka kakhulu, futhi alungele abasebenzi bezokwelapha ukuthi banyakaze futhi basebenze; basebenzisa ukuxhumana kwe-Bluetooth, u-opharetha akadingi ukuchitha isikhathi esiningi ekumiseni nasekusetheni; izingxenye ezishintshayo zamahhala uma isevisi yangemuva kokuthengisa itholakala. I-LnkMed izibophezele ekuhlinzekeni ngemikhiqizo namasevisi asezingeni eliphezului-radiology kanye ne-imaging.

I-Component Material Choice Ibalulekile
Ukuba khona kwezingxenye kazibuthe ngaphakathi komhubhe wesithwebuli se-MRI kunamandla okuphazamisa ukufana kwenkundla, futhi nenani elincane kakhulu lamagnetism lingaba nomthelela kwikhwalithi yesithombe se-MRI. Ngenxa yalokhu, kubalulekile ukuthi abakhiqizi bemishini yezokwelapha bafune izakhi, njengama-capacitor angaguquki, ama-trimmer capacitor, ama-inductors, nezixhumi, ezakhiwe ngezinsimbi ezihlanzeke kakhulu ezingenawo noma yimuphi uzibuthe olinganisekayo.
Ukunamathela kule mfuneko kuqala ngokulandelelwa okuqinile nezinqubo zokuhlola, kanye nesisekelo esiqinile sobuchwepheshe besayensi yezinto zokwakha. Isibonelo, ama-capacitor amaningi akhiwe ngokuqedwa kwesithiyo se-nickel ukuze alondoloze ukuqina; nokho, izici kazibuthe ze-nickel zenza i-capacitor ingafaneleki ukusetshenziswa ezinhlelweni zokuthwebula izithombe. Ngokufanayo, ithusi elithengiswayo, enye impahla esetshenziswa njalo, nayo ayizifanele lezi zinhloso.
Ukunaka okunjalo ngokucophelela emininingwaneni ezingeni lengxenye kuvimbela ukuhlanekezela futhi kunciphisa isidingo sokulungiswa kwesithombe. Ngakho-ke, odokotela bangakwazi ukuhlola ngempumelelo futhi baxilonga iziguli ngaphandle kokudinga izinqubo ezihlaselayo.
