Kuphatikizika kwa luntha lochita kupanga (AI) ndi ukadaulo wapamwamba kwambiri wojambulira zithunzi kukuyambitsa nthawi yatsopano mu chisamaliro chaumoyo, kupereka mayankho olondola, ogwira ntchito, komanso otetezeka - pamapeto pake kusintha zotsatira za chisamaliro cha odwala.
Mu njira zamankhwala zomwe zikusintha mofulumira masiku ano, kupita patsogolo kwa kujambula zithunzi kwasintha njira zodziwira matenda, zomwe zathandiza kuzindikira matenda msanga komanso kupereka njira zabwino zodziwira matenda. Pakati pa zinthu zatsopanozi, Photon Counting Computed Tomography (PCCT) imadziwika kuti ndi njira yosinthira zinthu. Ukadaulo wojambula zithunzi wa m'badwo wotsatirawu umaposa kwambiri machitidwe achikhalidwe a computed tomography (CT) pankhani ya kulondola, kugwira ntchito bwino, komanso chitetezo. PCCT yakonzedwa kuti isinthe njira zodziwira matenda ndikukweza muyezo wa mayeso a odwala.
Kuwerengera Photon Kuwerengera Tomography Yowerengera (PCCT)
Makina achikhalidwe a CT amadalira zida zowunikira zomwe zimagwiritsa ntchito njira ziwiri kuti ziwerengere mphamvu yapakati ya ma photon a X-ray (tinthu tating'onoting'ono ta mphamvu yamagetsi) pojambula zithunzi. Njira imeneyi ingafanizidwe ndi kusakaniza mitundu yosiyanasiyana yachikasu kukhala mtundu umodzi, wofanana—njira yowerengera yomwe imaletsa tsatanetsatane ndi kulunjika.
Koma PCCT imagwiritsa ntchito zida zamakono zowunikira zomwe zimatha kuwerengera ma photon payokha mwachindunji panthawi ya X-ray scan. Izi zimathandiza kusankha mphamvu molondola, monga kusunga mitundu yonse yapadera yachikasu m'malo mowaphatikiza kukhala imodzi. Zotsatira zake ndi zithunzi zatsatanetsatane komanso zapamwamba zomwe zimathandiza kuzindikira minofu bwino komanso kujambula zithunzi zambirimbiri, zomwe zimapereka kulondola kwambiri kwa matenda.
Kujambula Koyenera Kwambiri
Chiyerekezo cha Calcium cha Mitsempha ya Mtima, chomwe chimatchedwa chiŵerengero cha calcium, ndi mayeso ofunikira nthawi zambiri omwe amagwiritsidwa ntchito poyesa kuchuluka kwa calcium m'mitsempha ya mtima. Chiŵerengero chopitirira 400 chimasonyeza kuchuluka kwa plaque, zomwe zimaika wodwalayo pachiwopsezo chachikulu cha matenda a mtima kapena sitiroko. Kuti muwone bwino momwe mitsempha ya mtima imachepa, CT Coronary Angiogram (CTCA) nthawi zambiri imagwiritsidwa ntchito. Mayesowa amapanga zithunzi zamitundu itatu (3D) za mitsempha ya mtima kuti zithandize kuzindikira matenda.
Komabe, kuyika kwa calcium m'mitsempha ya mtima kungasokoneze kulondola kwa CTCA. Kuyika kumeneku kungayambitse "zinthu zopanga," komwe zinthu zokhuthala, monga calcifications, zimaoneka zazikulu kuposa momwe zilili. Kusokonekera kumeneku kungayambitse kuyerekezera mopitirira muyeso kuchuluka kwa kuchepa kwa mitsempha yamagazi, zomwe zingakhudze kupanga zisankho zachipatala.
Chimodzi mwa zabwino kwambiri za Photon Counting Computed Tomography (PCCT) ndi kuthekera kwake kupereka chithunzi chabwino kwambiri poyerekeza ndi ma CT scanner achikhalidwe. Kupita patsogolo kwaukadaulo kumeneku kumachepetsa zoletsa zomwe zimachitika chifukwa cha calcifications, zomwe zimapangitsa kuti zithunzi za mitsempha ya mtima ziwoneke bwino komanso molondola. Mwa kuchepetsa mphamvu ya zinthu zakale, PCCT imathandiza kuchepetsa njira zosafunikira zolowera ndikuwonjezera kudalirika kwa matenda.
Kupititsa patsogolo Kulondola kwa Kuzindikira
PCCT imachita bwino kwambiri posiyanitsa minofu ndi zinthu zosiyanasiyana, kuposa luso la CT wamba. Vuto lalikulu mu CTCA ndi kujambula mitsempha ya mtima yomwe ili ndi ma stenti achitsulo, omwe nthawi zambiri amapangidwa kuchokera ku chitsulo chosapanga dzimbiri kapena ma alloy apadera. Ma stenti amenewa amatha kupanga zinthu zambiri mu CT scan yachikhalidwe, kubisa tsatanetsatane wofunikira.
Chifukwa cha kuthekera kwake kopambana komanso luso lake lapamwamba lochepetsa zinthu zakale, PCCT imapereka zithunzi zakuthwa komanso zatsatanetsatane za ma stenti a mtima. Kusintha kumeneku kumathandiza madokotala kuwunika ma stenti molimba mtima, kukulitsa kulondola kwa matenda ndikuwongolera zotsatira za odwala.
Kuzindikira Kwambiri Kulondola
Kuwerengera Photon Kuwerengera Computed Tomography (PCCT) kumaposa CT yachikhalidwe pakutha kwake kusiyanitsa minofu ndi zinthu zosiyanasiyana. Chovuta chachikulu mu CT Coronary Angiography (CTCA) ndikuwunika mitsempha ya mtima yokhala ndi ma stents achitsulo, omwe nthawi zambiri amapangidwa kuchokera ku chitsulo chosapanga dzimbiri kapena ma alloys. Ma stents amenewa nthawi zambiri amapanga zinthu zambiri mu CT scans yodziwika bwino, kubisa tsatanetsatane wofunikira. Kuwona bwino kwa PCCT komanso njira zapamwamba zochepetsera zinthu zimathandiza kuti ipange zithunzi zakuthwa komanso zatsatanetsatane za ma stents, zomwe zimapangitsa kuti kulondola kwa matenda kukhale kolondola kwambiri.
Kusintha Zithunzi za Oncology
PCCT imathandizanso kusintha kwambiri pankhani ya khansa, popereka kulondola kopambana pakupeza ndi kusanthula chotupa. Imatha kuzindikira zotupa zazing'ono ngati 0.2 mm, ndikupeza matenda a khansa omwe CT yachikhalidwe ingawanyalanyaze. Kuphatikiza apo, luso lake lojambula zithunzi zamitundu yambiri—kujambula deta m'milingo yosiyanasiyana ya mphamvu—limapereka chidziwitso chofunikira pa kapangidwe ka minofu. Kujambula kwapamwamba kumeneku kumathandiza kusiyanitsa pakati pa minofu yopanda poizoni ndi yoyipa molondola, zomwe zimapangitsa kuti pakhale njira yolondola kwambiri yodziwira khansa komanso kukonzekera bwino chithandizo.
Kuphatikiza kwa AI kwa Kuzindikira Kwabwino
Kuphatikizika kwa PCCT ndi luntha lochita kupanga (AI) ndi kuphunzira kwa makina kwakonzedwa kuti kufotokozenso njira zogwirira ntchito zowunikira matenda. Ma algorithms oyendetsedwa ndi AI amawonjezera kutanthauzira kwa zithunzi za PCCT, kuthandiza akatswiri a radiology pozindikira mawonekedwe ndikupeza zolakwika mwachangu. Kuphatikiza kumeneku kumawonjezera kulondola komanso liwiro la matenda, ndikutsegula njira yothandizira odwala mosavuta komanso moyenera.

Kuzindikira Zinthu Mwabwino Kwambiri kudzera mu Kuphatikizana kwa AI
Kuphatikiza kwa Photon Counting Computed Tomography (PCCT) ndi luntha lochita kupanga (AI) ndi kuphunzira kwa makina kukusinthira njira zowunikira matenda. Ma algorithms oyendetsedwa ndi AI amachita gawo lofunikira pakutanthauzira ma PCCT scan mwa kuzindikira bwino mawonekedwe ndikupeza zolakwika, zomwe zimathandiza kwambiri akatswiri a radiology. Mgwirizanowu umathandizira kulondola komanso kuthamanga kwa matenda, zomwe zimapangitsa kuti chisamaliro cha odwala chikhale chogwira mtima komanso chosavuta.
Kupita Patsogolo Koyendetsedwa ndi AI mu Kujambula
Kujambula zithunzi zachipatala kukulowa mu gawo losintha, loyendetsedwa ndi PCCT yolimbikitsidwa ndi AI komanso njira zapamwamba za Tesla MRI. Kwa odwala omwe akuganiziridwa kuti ali ndi mitsempha ya mtima kapena ma stenti oyikidwa, PCCT imapereka ma scan olondola kwambiri, kuchepetsa kudalira njira zodziwira matenda. Kuzindikira kwake kosayerekezeka komanso luso lake lojambula zithunzi zambiri kumathandiza kuzindikira msanga zotupa zazing'ono ngati 2 mm, kusiyanitsa bwino minofu, komanso kupeza bwino matenda a khansa.
Kwa anthu omwe ali pachiwopsezo cha matenda a m'mapapo, monga osuta fodya, PCCT imapereka njira yothandiza yodziwira matenda a m'mapapo msanga, zonse zomwe zimapangitsa odwala kukhudzidwa ndi kuwala kochepa - kofanana ndi ma X-ray awiri pachifuwa. Pakadali pano, MRI yapamwamba ya Tesla ikuwoneka yothandiza kwambiri kwa okalamba pothandiza kuzindikira msanga matenda monga vuto lochepa la kuzindikira, osteoarthritis, ndi matenda ena okhudzana ndi ukalamba, zomwe pamapeto pake zimawonjezera moyo wabwino kudzera mu njira zochiritsira panthawi yake.
Chiyembekezo Chatsopano mu Kujambula Zithunzi Zachipatala
Kuphatikizidwa kwa AI ndi ukadaulo wapamwamba kwambiri wojambulira zithunzi monga PCCT ndi Tesla MRI yapamwamba kukuwonetsa kupita patsogolo kwakukulu pakuwunika matenda azachipatala. Zatsopanozi zimapereka kulondola kwakukulu, magwiridwe antchito abwino, komanso chitetezo chowonjezereka, zomwe zimapangitsa kuti tsogolo la odwala likhale labwino kuposa kale lonse. Nthawi yatsopanoyi yopezera chithandizo chamankhwala ikutsegulira njira zothetsera mavuto azaumoyo zomwe zimapangidwira munthu payekha komanso mwachangu.
