Kodi ndi zinthu ziti zomwe zachitika posachedwapa mu Medical Imaging?

Kuyambira pomwe zidayamba m'ma 1960 mpaka m'ma 1980, Magnetic Resonance Imaging (MRI), computerized tomography (CT) scans, ndi positron emission tomography (PET) scans zapita patsogolo kwambiri. Zipangizo zojambulira zamankhwala izi zomwe sizimavulaza anthu zapitilizabe kusintha ndi kuphatikiza luntha lochita kupanga (AI), njira zowonjezera zosonkhanitsira deta yosaphika, ndi kusanthula ziwerengero zambiri, zomwe zimathandiza kumvetsetsa bwino ndi kusanthula machitidwe athu amkati.

Kupita patsogolo kwa PET ndi CT scans

Kujambula kwa PET nthawi zambiri kumatenga mphindi 45 mpaka ola limodzi kuti kumalizidwe ndipo kumatha kupanga zithunzi zosiyana za kukula kwa chotupa muubongo, mapapo, khomo lachiberekero, ndi madera ena a thupi. Kupita patsogolo kumeneku kwawonjezera mphamvu ya njirayi, kuphatikiza mapulogalamu owongolera kusayenda bwino kwa mayendedwe ndikulola kuwunika kwa algorithmic kuti adziwiretu komwe kuli chipolopolo mkati mwa minofu yoyenda.

Kusayenda bwino kwa chinthu kumachitika pamene gawo la chinthucho likusuntha panthawi yojambula chithunzi cha PET, zomwe zimapangitsa kuti zikhale zovuta kuwunika ndikusanthula kuchuluka kwa chinthucho. Pofuna kuchepetsa kuyenda kwa chinthucho panthawi yojambula PET, akatswiri azaumoyo amagwiritsa ntchito njira yopezera zinthu mopanda denga, kugawa nthawi yojambula m'mabokosi angapo. Mwa kugawa njira yojambulira m'mabokosi 8-10, pulogalamuyi imatha kuyembekezera malo a chinthucho panthawi inayake kapena malo enaake, kutengera zomwe wogwiritsa ntchito amakonda. Kuneneratu kumeneku kumachitika poganizira malo a chinthucho mkati mwa mabokosi a chinthucho. Njira yojambulira ya PET yotetezedwa imachepetsa bwino kusayenda bwino kwa chinthucho, zomwe zimapangitsa kuti ntchitoyo ikhale yolimba/mtengo wosinthika wokhazikika (SUV). Deta ya PET ikagwirizana ndi deta ya CT, njira yonseyi imadziwika kuti 4D CT scanning.

Komabe, pali malire odziwika bwino okhudzana ndi njirayi. Kugwiritsa ntchito njira zotchingira zithunzi kumapangitsa kuti phokoso liwonjezeke chifukwa chopeza deta yambiri. Njira zingapo zothetsera vutoli ndi monga Q-freeze, Oncofreeze, ndi nthawi youluka (ToF).

Momwe kusokonekera kwa chithunzi kumakonzedwera mkati mwa PET ndi CT scans

Kukonza zithunzi pogwiritsa ntchito Q-freeze, pogwiritsa ntchito geti lopeza zithunzi, kumatanthauza kusonkhanitsa ndi kulembetsa zithunzi zonse zopangidwa. Kulembetsa kumeneku kumachitika mkati mwa chithunzi, kusonkhanitsa ndi kukonzanso deta yonse yopangidwa kuchokera ku PET scan kuti apange chithunzi chomaliza chokhala ndi phokoso lochepa komanso kusokonekera.

OncoFreeze, njira yowonetsera zithunzi, imafanana ndi Q-freeze m'njira zina, ngakhale kuti ndi yosiyana kwambiri. Kukonza mayendedwe kumachitika mu sinogram space (data space raw). Pambuyo potenga chithunzi choyamba, zithunzi zosawoneka bwino zimawonetsedwa patsogolo ndikuyerekezeredwa ndi data yowonetsedwa ya benchi yochitira opaleshoni ndi backproject sinogram ratios. Izi zimapangitsa kuti chithunzi chomaliza chisinthidwe kutengera chithunzi chokonzedwa chomwe chachotsedwa.

Kujambula mawonekedwe a mafunde a kupuma panthawi ya PET scans pamodzi ndi CT scans kungapangitse kuti chithunzi chikhale bwino. Kulinganiza bwino kungawonetsedwe mwa kugwirizanitsa mawonekedwe a mafunde a PET scans, njira yachikhalidwe, ndi mawonekedwe a mafunde a CT scans, njira yomwe yapangidwa posachedwapa.

Monga tonse tikudziwira, chitukuko cha makampani opanga zithunzi zachipatala sichingasiyanitsidwe ndi chitukuko cha zida zamankhwala zingapo - majekeseni osiyanitsa ndi zinthu zina zothandizira - zomwe zimagwiritsidwa ntchito kwambiri m'munda uno. Ku China, komwe kumadziwika ndi makampani opanga zinthu, kuli opanga ambiri otchuka kunyumba ndi kunja chifukwa chopanga zida zojambula zithunzi zachipatala, kuphatikizapoLnkMedKuyambira pomwe idakhazikitsidwa, LnkMed yakhala ikuyang'ana kwambiri pa ntchito yopangira majekeseni otsutsana ndi mpweya woipa kwambiri. Gulu la mainjiniya la LnkMed limatsogozedwa ndi PhD yokhala ndi zaka zoposa khumi zokumana nazo ndipo ikuchita kafukufuku ndi chitukuko mozama. Motsogozedwa ndi iye,Injector ya mutu umodzi ya CT, Injector ya mutu wa CT iwiri, Injector ya MRI contrastndiInjector yotsutsana ndi kuthamanga kwa magazi (Angiography)Zapangidwa ndi zinthu izi: thupi lolimba komanso laling'ono, mawonekedwe osavuta komanso anzeru ogwirira ntchito, ntchito zake zonse, chitetezo champhamvu, komanso kapangidwe kolimba.
