Izithwebuli ze-CT-computer inhlanganisela yenqubo yekhompyutha yezithombe eziningi ze-X-ray ezithathwe ezinhlangothini ezahlukene ukukhiqiza idatha ye-3D.
“Izikena zamanje ze-x-ray CT zikhiqiza izithombe ezinemitshina ehlanganisa amandla [ama-EID], asuselwa kubuchwepheshe bokuguqula okungaqondile: Ama-X-ray photons aqala aguqulwe abe ukukhanya okukhanyayo kusetshenziswa izinto ze-scintillator, bese kuthi ama-photon abonakalayo akhiqize amasiginali kagesi esebenzisa i-photodiode, ”Ngokusho kukaLeti. "Ngakolunye uhlangothi, imodyuli yokubala i-Photon, iguqula ngqo ama-x-ray photons abe amasiginali we-elektroniki anenzuzo ephezulu yokuguqula."
Ngenkathi ama-EID ebhalisa amandla aphelele afakwe kwi-pixel ngesikhathi esithile, enza isithombe se-monochrome esibonisa ukuminyana kwezitho zomzimba, ama-PCDM abala i-photon ngayinye futhi avumela amandla we-photon ukuba ahlukaniswe, avumela “ukucaciswa okuqondile kwenombolo ye-athomu noma iziphi izakhi zamakhemikhali nomehluko wezinto eziningi zokuqhathanisa ezikhona emzimbeni ”, kusho uLeti.
Idivayisi ihlanganiswe ne-x-ray scanner prototype evela kwa-Siemens Healthineers, eyaqamba umqondo.
"Umqondo wabakwa-Nokia Healthineers wokuhlanganisa ama-PCDM kuma-x-ray CT scanner wawumusha futhi abukho ubuchwepheshe obabukhona ngenkathi i-CEA-Leti iqala ukusebenza ngalokhu," kusho umphathi we-CEA-Leti wezokusebenzisana kwezimboni uLoick Verger. "Inselelo yezobuchwepheshe - umsindo ophansi ngezinga eliphezulu lokubala, ukuhlukaniswa kwamandla amabili, kanye nokuvuthwa okwanele ukuhlanganiswa kusikena se-X-ray CT - bekukhulu kakhulu."
UMayo Clinic wase-US uzame umshini wakwa-Nokia.
"Izithombe zeziguli ezingaphezu kwezingama-300 ezikhiqizwe ngalobu buchwepheshe zikhombisa njalo ukuthi imihlomulo yezinkolelo zalolu hlobo yetheknoloji yobuchwepheshe iveza izinzuzo eziningi ezibalulekile zomtholampilo," kusho uprofesa waseMayo Clinic we-physics yezokwelapha uCynthia McCollough. “Ukushicilelwa yithimba lethu locwaningo kukhombise ukulungiswa kwezindawo okuthuthukile, kwehlise imisebe noma izidingo zomthamo wokuqhathanisa iodine, kanye nokwehla kwamazinga omsindo wezithombe nezinto zobuciko. Ngaphezu kwalokho, amandla okuthola ngasikhathi sinye ama-database amaningi angama-150μm resolution, ngalinye limele i-spectrum ehlukile yamandla, kulindeleke ukuthi liholele ekusetshenzisweni okusha komtholampilo. ”
