Kubatanidzwa kwehungwaru hwekugadzira (AI) nehunyanzvi hwepamusoro hwekufungidzira kuri kutanga nguva itsva muhutano, zvichipa mhinduro dzakarurama, dzinoshanda, uye dzakachengeteka—zvichizopedzisira zvavandudza mhedzisiro yekutarisira varwere.
Mumamiriro ekurapa ari kuchinja nekukurumidza nhasi, kufambira mberi mukutora mifananidzo kwakachinja kuongororwa kwezvirwere, zvichiita kuti zvikwanise kuonekwa nekukurumidza uye kufanotaura zviri nani. Pakati pezvinhu zvitsva izvi, Photon Counting Computed Tomography (PCCT) inoonekwa sebudiriro inochinja. Iyi tekinoroji yekutora mifananidzo yechizvarwa chinotevera inodarika zvakanyanya masisitimu ekare e computed tomography (CT) maererano nekunyatsojeka, kushanda zvakanaka, uye kuchengetedzeka. PCCT yakagadzirirwa kutsanangura patsva maitiro ekuongorora uye kusimudzira mwero wekuongorora kwevarwere.
Kuverenga Photon Kuverenga Tomography (PCCT)
Masisitimu ekare eCT anovimba nema detector anoshandisa maitiro ane matanho maviri ekufungidzira avhareji yesimba rema photon eX-ray (tinhu tema electromagnetic radiation) panguva yekutora mifananidzo. Maitiro aya anogona kufananidzwa nekubatanidza mavara akasiyana-siyana eyero kuita ruvara rumwe chete, rwakafanana—maitiro avhareji anoganhurira ruzivo uye kujeka.
PCCT, kune rumwe rutivi, inoshandisa michina yekuongorora yepamusoro inokwanisa kuverenga maphoton ega ega zvakananga panguva yeX-ray scan. Izvi zvinobvumira kusiyanisa simba kwakaringana, kwakafanana nekuchengetedza mavara ese akasiyana eyero pane kuabatanidza kuita rimwe chete. Mugumisiro wacho mifananidzo yakadzama, ine resolution yepamusoro inogonesa kutsanangurwa kwetishu yepamusoro uye mifananidzo ye multispectral, zvichipa kunyatsoongorora kusati kwamboitika.
Kunyatsoongorora Mifananidzo
Chiyero cheCalcium Score cheCoronary Artery, chinowanzozivikanwa seCalcium Score, ibvunzo inowanzo kumbirwa inoshandiswa kuyera calcium deposits mu coronary arteries. Chiyero chinodarika 400 chinoratidza kuunganidzwa kukuru kweplaque, zvichiisa murwere panjodzi yakakura yekurwara nemoyo kana sitiroko. Kuti uwane ongororo yakadzama ye coronary artery detensing, CT Coronary Angiogram (CTCA) inowanzo shandiswa. Iyi bvunzo inogadzira mifananidzo ye3D ye coronary arteries kuti ibatsire pakuongorora chirwere ichi.
Zvisinei, calcium yakaiswa mutsinga dzemwoyo inogona kukanganisa kururama kweCTCA. Iyi calcium inogona kutungamira ku "zvinhu zvinokura," uko zvinhu zvakawandisa, zvakaita se calcifications, zvinoita sezvakakura kupfuura zvazviri chaizvo. Kukanganiswa uku kunogona kukonzera kuwedzeredzwa kwehuwandu hwe artery inopera, izvo zvinogona kukanganisa sarudzo dzekiriniki.

PCCT inochinjawo zvinhu munyaya dzekenza, ichipa kururama kusingaenzaniswi pakuona nekuongorora bundu. Inogona kuona bundu diki se 0.2 mm, ichibata kenza idzo CT yechinyakare ingasaona. Pamusoro pezvo, kugona kwayo kuona mifananidzo ye multispectral—kubata data kubva pamazinga akasiyana esimba—kunopa ruzivo rwakakosha mukuumbwa kwenyama. Iyi mifananidzo yepamusoro inobatsira kusiyanisa pakati penyama dzisina njodzi nedzinouraya zvakanyatsonaka, zvichitungamira pakuronga kenza nemazvo uye kuronga kurapwa kunobudirira.
Kubatanidzwa kweAI kweOptimised Diagnostics
Kubatanidzwa kwePCCT nepfungwa dzekugadzira (AI) uye kudzidza kwemuchina kwakagadzirirwa kutsanangura patsva mashandiro ekuongorora mifananidzo. Maalgorithms anoshandisa AI anovandudza kududzirwa kwemifananidzo yePCCT, achibatsira vanachiremba veX-ray nekuona mapatani uye kuona zvisina kujairika nekushanda zvakanyanya. Kubatanidzwa uku kunowedzera kururama nekumhanya kwekuongorora, zvichigadzira nzira yekutarisira varwere zviri nyore uye zvinobudirira.

Kufungidzira kwekurapa kuri kupinda muchikamu chekuchinja, kuchishandiswa neAI-enhanced PCCT uye high-Tesla MRI systems yepamusoro. Kune varwere vane kufungidzirwa kuti vane coronary artery blockage kana kuti implanted stents, PCCT inopa scans dzakarurama zvinoshamisa, zvichideredza kuvimba nenzira dzekuongorora dzinopinda mumuviri. Kugona kwayo kuongorora kusingaenzaniswi uye multispectral imaging kunoita kuti zvikwanisike kuona bundu nekukurumidza, diki se2 mm, kusiyanisa kwenyama nemazvo, uye kuongororwa kwegomarara zviri nani.
Kune vanhu vari panjodzi yekubatwa nechirwere chemapapu, vakaita sevanoputa fodya, PCCT inopa nzira inoshanda yekuona bundu remapapu nekukurumidza, ukuwo varwere vachiwana mwaranzi shoma—zvichienzaniswa neX-ray mbiri dzechipfuva. Panguva iyi, high-Tesla MRI iri kuratidza kukosha kukuru kuvanhu vakwegura nekuita kuti zvirwere zvakaita sekusagadzikana kwepfungwa, osteoarthritis, nezvimwe zvirwere zvine chekuita nekukwegura zvionekwe nekukurumidza, zvichizopedzisira zvawedzera hupenyu hwavo kuburikidza nekurapa panguva yakakodzera.
