Makina opangira makina a CT ophatikizira zithunzi zambiri za X-ray zojambulidwa mosiyanasiyana kuti apange zidziwitso za 3D.
"Makina amakono a X-ray CT amapanga zithunzi zokhala ndi zida zophatikizira mphamvu [ma EID], zomwe zimazikidwa ndi ukadaulo wosasintha wosintha: Zithunzi za X-ray zimasinthidwa kukhala kuwala kowonekera pogwiritsa ntchito zinthu za scintillator, kenako ma photon owoneka amatulutsa ma elektroniki pogwiritsa ntchito photodiode, ”Malinga ndi Leti. "Komano gawo lowerengetsera makina a Photon, limasintha mwachindunji zithunzi za x-ray kuti zikhale zida zamagetsi zomwe zimatha kusintha kwambiri."
Ngakhale ma EID amalembetsa mphamvu zonse zomwe zimayikidwa mu pixel nthawi yayitali, ndikupanga chithunzi cha monochrome chosonyeza kuchuluka kwa ziwalo za thupi, ma PCDM amawerengera chithunzi chilichonse ndikulola mphamvu ya photon kuti igawidwe, kulola "kudziwa molondola nambala ya atomiki ya zinthu zilizonse zamankhwala komanso kusiyanasiyana kwa mitundu yosiyanasiyana yomwe ilipo mthupi ”, adatero Leti.
Chipangizocho chaphatikizidwa ndi mtundu wa x-ray scanner kuchokera ku Siemens Healthineers, omwe adapanga lingaliro.
"Lingaliro la Nokia Healthineers kuphatikiza ma PCDM mu makina a x-ray CT linali latsopano ndipo palibe ukadaulo womwe ulipo pomwe CEA-Leti idayamba kugwira ntchito iyi," atero a Loick Verger, manejala wa mgwirizano wamafakitale ku CEA-Leti. "Vuto laukadaulo - phokoso lochepa pakuwerengera kwambiri, magawidwe awiri amagetsi, komanso kukhwima kokwanira kuphatikizidwa mu X-ray CT scanner - zinali zazikulu."
US Mayo Clinic yayesa makina a Nokia.
"Zithunzi za odwala opitilira 300 omwe amapangidwa ndi ukadaulo uwu zakhala zikuwonetsa kuti phindu laukadaulo wa mtundu uwu wa ma detector limapereka maubwino angapo azachipatala," pulofesa wa Mayo Clinic wa sayansi ya zamankhwala Cynthia McCollough. “Zofalitsa zomwe gulu lathu lofufuza zawonetsa zikuwongolera kukonza kwa malo, kuchepa kwa ma radiation kapena zofunikira za mlingo wa ayodini, ndikuchepetsa phokoso la zithunzi ndi zinthu zina. Kuphatikiza apo, kuthekera kwakanthawi kopezeka ndi ma nkhokwe angapo a ma XMUMXμm resolution, omwe akuyimira mphamvu yamagetsi osiyanasiyana, akuyembekezeka kutsogolera kuchipatala chatsopano. ”
