Pano, tichaongorora muchidimbu maitiro matatu ari kuvandudza matekinoroji ekufungidzira kwekurapa, uye nekudaro, kuongororwa kwezvirwere, mhedzisiro yevarwere, uye kuwanikwa kwehutano. Kuti tiratidze maitiro aya, tichashandisa magnetic resonance imaging (MRI), iyo inoshandisa masaini eredhiyo (RF).
Nyanzvi dzezvehutano dzinoshandisa nzira dzakasiyana-siyana dzekurapa kuti dzione maumbirwo emuviri nemabasa awo pasina kupindira. Nzira idzi dzinokosha pakuongorora zvirwere nekukuvara, kutarisa kushanda kwekurapa, uye kuronga nzira dzekuvhiya. Nzira yega yega yekutora mifananidzo yakagadzirirwa kushandiswa kwekiriniki.
Kusanganisa Maitiro Ekufananidzira
Tekinoroji dzemifananidzo dzakasanganiswa dzinoshandisa simba rekubatanidza nzira dzakasiyana-siyana kuti dzigadzire maonero akazara emuviri. Nyanzvi dzezvehutano dzinoshandisa mifananidzo iyi kusimudzira kuongororwa nekurapwa kwevarwere.
Semuenzaniso, PET/MRI scans inobatanidza positron emission tomography (PET) scans uye MRI scans. MRI inopa mifananidzo yakadzama yezvivakwa zvemukati memuviri nemabasa azvo, nepo PET ichiratidza kusarongeka uchishandisa tracers. Kusanganiswa uku kunobatsira zvikuru mukurapa zvirwere zvakaita sechirwere cheAlzheimer, pfari, uye bundu reuropi. Kare, kubatanidza PET neMRI kwaisakwanisika nekuda kwemagineti ane simba eMRI anokanganisa ma detector emifananidzo yePET. Scans dzaifanira kuitwa dzakasiyana dzozobatanidzwa, zvichisanganisira kugadzirisa mifananidzo kwakaoma uye kurasikirwa nedata. Sekureva kweStanford Medicine, musanganiswa wePET/MRI wakanyatsojeka, wakachengeteka, uye uri nyore pane kuita scans dzakasiyana.
Kuwedzera Kushanda Kwemagadzirirwo Emafirimu
Kuvandudzwa Kwekushanda kunoita kuti mufananidzo uve nani uye uwane ruzivo rwakanyatsojeka rwekuongorora nekurapa. Semuenzaniso, vaongorori vava kukwanisa kushandisa masisitimu eMRI ane simba remunda rinosvika 7T. Kuvandudzwa uku kwekushanda kunoita kuti signal-to-noise ratio (SNR), zvichikonzera mhedzisiro yemifananidzo yakajeka uye yakadzama. Panewo chido chekuita kuti MRI receiver dzive nedhijitari zvakanyanya. Nekuwanikwa kwe higher resolution uye higher frequency analog-to-digital converters (ADCs), pane mukana wekushandura ADC kuenda kuRF coil, iyo inogona kuderedza ruzha uye kuwedzera SNR kana kushandiswa kwesimba kuchishandiswa nemazvo. Mabhenefiti akafanana anogonawo kuwanikwa nekuwedzera mamwe maRF coils ega ega kusystem. Kuisa pamberi kuvandudzwa kwekushanda kunoshandura kuvandudza zvinhu zvemurwere zvakaita senguva dzekuongorora nemitengo.
Kugadzira Midziyo Yemifananidzo Yekutakura Zvinhu
Nekugadzirwa kwayo, mimwe michina yekuongorora varwere nekurapa yakatanga munzvimbo dzakarongwa kuti ishande zvakanaka (semuenzaniso, MRI suite).
Kuongororwa kwekombiyuta (CTuyemagnetic resonance imaging (MRI) mienzaniso yakanaka.
Kunyange zvazvo nzira idzi dzekutora mifananidzo dzichishanda pakuongorora chirwere, dzinogona kuva dzinonetsa varwere vanorwara zvakanyanya. Kufambira mberi kwetekinoroji kuri kutamisa mabasa aya ekuongorora chirwere kuenda kunzvimbo dziri varwere.
Kana zvasvika pamidziyo isingafambiki semichina yeMRI, kugadzira dhizaini yekutakurika kunosanganisira kufunga nezvezvinhu zvakaita sehukuru nehuremu, simba, simba remagineti, mutengo, mhando yemufananidzo, uye kuchengetedzeka. Padanho rezvikamu, sarudzo dzakadai sema capacitor anoshanda zvakanyanya dzinoita basa rakakosha mukuona kuti magetsi akagadzirwa zvakanaka uye anoshanda zvakanaka mukati mehurongwa hudiki, hunotakurika.

Nekuvandudzwa kwetekinoroji yemifananidzo yekurapa, kune makambani akawanda anouya anogona kupa zvigadzirwa zvemifananidzo, zvakaita semajekiseni nemasirinji. Tekinoroji yekurapa yeLnkMed ndeimwe yadzo. Tinopa huwandu hwakazara hwezvigadzirwa zvekuongorora zvekubatsira:Majekiseni eCT，Jekiseni reMRIuyejekiseni reDSA. Dzinoshanda zvakanaka nemarudzi akasiyana-siyana eCT/MRI scanner akadai seGE, Philips, Siemens. Kunze kweinjector, tinopawo sirinji nechubhu zvinoshandiswa pamhando dzakasiyana dzeinjector dzinosanganisiraMedrad/Bayer, Mallinckrodt/Guerbet, Nemoto, Medtron, Ulrich.
Izvi ndizvo zvatinogona kuita: nguva yekutumira nekukurumidza; Zvitupa zvakakwana, makore mazhinji eruzivo rwekutumira kunze kwenyika, maitiro ekuongorora emhando yepamusoro, zvigadzirwa zvinoshanda zvizere.
Iwe neboka rako makagamuchirwa kuuya kuzobvunzana, tinopa basa rekugamuchira vaenzi maawa makumi maviri nemana.
