Zochitika Zokhudza Kujambula Zachipatala Zomwe Zatikopa Chidwi

Pano, tifufuza mwachidule njira zitatu zomwe zikukulitsa ukadaulo wojambula zithunzi zachipatala, ndipo motero, kuzindikira matenda, zotsatira za odwala, ndi kupezeka kwa chithandizo chamankhwala. Kuti tifotokoze zomwe zikuchitikazi, tigwiritsa ntchito kujambula zithunzi zamaginito (MRI), yomwe imagwiritsa ntchito zizindikiro za ma radio frequency (RF).

Akatswiri azaumoyo amadalira njira zosiyanasiyana zojambulira zithunzi zachipatala kuti azitha kuwona kapangidwe ndi ntchito zamkati mwa thupi mosasokoneza. Njirazi ndi zothandiza pozindikira matenda ndi kuvulala, kuyang'anira momwe chithandizo chimagwirira ntchito, komanso kukonzekera njira zochitira opaleshoni. Njira iliyonse yojambulira zithunzi imapangidwa kuti igwirizane ndi ntchito zinazake zachipatala.

Kuphatikiza Njira Zojambulira

Ukadaulo wophatikiza zithunzi umagwiritsa ntchito mphamvu yophatikiza njira zosiyanasiyana kuti upange mawonekedwe atsatanetsatane a thupi. Akatswiri azaumoyo amagwiritsa ntchito zithunzizi kuti awonjezere kuzindikira ndi kuchiza odwala.

Mwachitsanzo, ma PET/MRI scans amaphatikiza ma positron emission tomography (PET) scans ndi ma MRI scans. MRI imapereka zithunzi zatsatanetsatane za kapangidwe ka thupi lamkati ndi ntchito zake, pomwe PET imazindikira zolakwika pogwiritsa ntchito ma tracers. Kuphatikizika kumeneku ndikothandiza kwambiri pochiza matenda monga matenda a Alzheimer's, khunyu, ndi zotupa za muubongo. Kale, kuphatikiza ma PET ndi MRI sikunali kotheka chifukwa cha maginito amphamvu a MRI omwe amasokoneza zowunikira zithunzi za PET. Ma scans amayenera kuchitidwa padera kenako nkuphatikizana, zomwe zimaphatikizapo kukonza zithunzi mozama komanso kutayika kwa deta. Malinga ndi Stanford Medicine, kuphatikiza kwa PET/MRI ndikolondola kwambiri, kotetezeka, komanso kosavuta kuposa kuchita ma scan osiyana.

Kuwonjezeka kwa Magwiridwe Antchito a Kachitidwe ka Zithunzi

Kukweza Magwiridwe Antchito kumapangitsa kuti chithunzi chikhale bwino komanso kuti mudziwe zambiri zolondola pa matenda ndi chithandizo. Mwachitsanzo, ofufuza tsopano ali ndi mwayi wopeza makina a MRI okhala ndi mphamvu zoyambira mpaka 7T. Kusinthaku kwa magwiridwe antchito kumawonjezera chiŵerengero cha ma signal-to-noise (SNR), zomwe zimapangitsa kuti zithunzi ziwoneke bwino komanso mwatsatanetsatane. Palinso njira yopangira ma MRI receiver kukhala ogwirizana ndi digito. Popeza pali ma high resolution ndi ma higher frequency analog-to-digital converters (ADCs), pali mwayi wosinthira ADC ku RF coil, yomwe ingachepetse phokoso ndikuwonjezera SNR pamene mphamvu ikugwiritsidwa ntchito moyenera. Mapindu ofanana nawo angapezekenso powonjezera ma RF coil ambiri payokha pamakina. Kuika patsogolo kusintha kwa magwiridwe antchito kumatanthauza kukonza zinthu zomwe wodwala akukumana nazo monga nthawi yojambulira ndi ndalama.

Kupanga Zipangizo Zojambulira Kuti Zizitha Kunyamulika

Mwa kapangidwe kake, zida zina zowunikira odwala ndi chithandizo zinayamba m'malo olamulidwa kuti zigwire ntchito moyenera (monga, MRI suite).

Kujambula zithunzi pogwiritsa ntchito kompyuta (CTndikujambula kwa maginito (MRI) ndi zitsanzo zabwino kwambiri.

Ngakhale kuti njira zojambulira zithunzizi ndi zothandiza pozindikira matenda, zimatha kukhala zovuta kwambiri kwa odwala omwe ali ndi vuto lalikulu. Kupita patsogolo kwa ukadaulo tsopano kukusuntha ntchito zodziwira matendazi kupita komwe odwala ali.

Ponena za zipangizo zomwe nthawi zambiri sizimayenda monga makina a MRI, kupanga kapangidwe kake konyamulika kumaphatikizapo kuganizira zinthu monga kukula ndi kulemera, mphamvu, mphamvu ya maginito, mtengo, mtundu wa chithunzi, ndi chitetezo. Pa gawo la zinthu, zosankha monga ma capacitor apamwamba zimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti magetsi apangidwa bwino komanso moyenera komanso kuti zizindikiro zizigwiritsidwa ntchito bwino mkati mwa chimango chaching'ono, chonyamulika.

Ndi chitukuko cha ukadaulo wa kujambula zithunzi zachipatala, pali makampani ambiri omwe amatha kupereka zinthu zojambulira zithunzi, monga majakisoni ndi ma syringe. Ukadaulo wa zamankhwala wa LnkMed ndi umodzi mwa iwo. Timapereka zinthu zonse zothandizira matenda:Majakisoni a CT，Jakisoni wa MRIndijekeseni ya DSAAmagwira ntchito bwino ndi mitundu yosiyanasiyana ya CT/MRI scanner monga GE, Philips, Siemens. Kupatula injector, timaperekanso syringe ndi chubu chomwe chingagwiritsidwe ntchito pa mitundu yosiyanasiyana ya injector kuphatikizapoMedrad/Bayer, Mallinckrodt/Guerbet, Nemoto, Medtron, Ulrich.

Izi ndi zomwe timachita bwino kwambiri: nthawi yotumizira mwachangu; Ziyeneretso zonse za satifiketi, zaka zambiri zokumana nazo zotumiza kunja, njira yabwino kwambiri yowunikira zinthu, zinthu zomwe zimagwira ntchito bwino.

Inu ndi gulu lanu mwalandiridwa kuti mudzakambirane, timapereka chithandizo cholandirira alendo maola 24.
