Nuclear Medical Imaging Solutions
Kodi imaging ya Medical ndi chiyani?
Kujambula kwamankhwala a nyukiliya (yomwe imatchedwanso kusanthula kwa radionuclide) ndi chida chodziwira matenda chifukwa sichimangowonetsa mawonekedwe a chiwalo kapena gawo la thupi, komanso ntchito ya chiwalo."Zidziwitso zogwira ntchito" izi zimathandiza kuti mankhwala a nyukiliya azindikire matenda ena ndi matenda osiyanasiyana mwamsanga kusiyana ndi mayesero ena achipatala omwe amapereka zambiri za anatomic (zapangidwe) za chiwalo kapena gawo la thupi.Mankhwala a nyukiliya amatha kukhala ofunikira pakuzindikira koyambirira, chithandizo, ndi kupewa matenda ambiri ndipo akupitilizabe kukula ngati chida champhamvu chachipatala.
KWA MABUKU AMBIRI OTHANDIZA UMOYO womwe umapereka kasamalidwe ka matenda achipatala omwe akhala gawo la moyo wawo watsiku ndi tsiku pazamankhwala azama radiology (ie, CT, MR, X-ray, PET, SPECT, etc.).Komabe, akatswiri m'mabungwewa, kuchokera kwa madokotala, akatswiri a zamakono, ndi olamulira, kwa ogwira ntchito a PACS/IT, akhala akumvanso ululu chifukwa chosowa mayankho oyenerera a PACS amitundu yosiyanasiyana.Njira zosagwiritsidwa ntchito kwambiri ndi PACS ndi njira zamanyukiliya zamanyukiliya, kuphatikiza PET-CT, SPECT-CT, nuclear cardiology, ndi general nuclear medicine.
Ngakhale kuti kuyerekezera kwa ma molekyulu a nyukiliya n’kochepa kwambiri poganizira kuchuluka kwa mayeso omwe amachitidwa pachaka, kufunikira kwake sikuyenera kunyalanyazidwa, ponse paŵiri kuchipatala komanso pazachuma.PET-CT yatsimikiziridwa kukhala de facto modality ikafika pakuzindikira khansa.Nuclear cardiology yakhala njira yosankhira pazamtima zosasokoneza.Mankhwala a nyukiliya wamba amapereka ntchito zambiri zofananira zomwe palibe njira zina zomwe zingagwirizane nazo.Pazachuma, PET-CT ndi nyukiliya yamtima akadali m'gulu la njira zobwezeredwa kwambiri pakuyerekeza kwa matenda.
Chomwe chimapangitsa kulingalira kwa ma cell a nyukiliya kukhala osiyana ndi ma radiology wamba ndikuti zithunzi zakale zimagwira ntchito za thupi, pomwe zotsirizirazo zimawonetsa mawonekedwe a thupi.Ichi ndichifukwa chake kujambula kwa nyukiliya nthawi zina kumatchedwanso metabolic imaging.Pofuna kusanthula ntchito za thupi kuchokera pazithunzi zomwe zapezedwa, zida zapadera zowonera ndi kusanthula zimafunikira.Zida izi ndizomwe zikusowa kwa ambiri a PACS masiku ano.
Pazifukwa izi, Kampani yochulukirachulukira yaukadaulo woyerekeza zamankhwala ikufuna kupanga m'badwo watsopano wa PET, SPECT.
Chifukwa Chosankha Kinheng:
1.Minimal pixel dimension kupezeka
2.Reduced optical crosstalk
3.Kufanana kwabwino pakati pa pixel kupita ku pixel / Gulu losanjikiza
4.TiO2/BaSO4/ESR/E60 zowunikira zilipo
5.Pixel Gap: 0.08, 0.1, 0.2, 0.3mm
Kuyesa kwa 6.Performance kupezeka
Kufananitsa Katundu Wazida:

Makina opangira kusonkhanitsa:
Kutengera kugwiritsa ntchito komaliza kwa magulu ophatikizika, pali mitundu yambiri yamakina opangidwa kuchokera ku Kingheng kuti akwaniritse ntchito yowunikira zachipatala ndi chitetezo.
1D Liner array amagwiritsidwa ntchito makamaka pakuwunika kwachitetezo, monga Bagger scanner, Aviation scanner, 3D scanner ndi NDT.Zinthu Zophatikizira CsI(Tl), GOS:Tb/Pr Film, GAGG:Ce, CdWO4 scintillator etc. Nthawi zambiri zimaphatikizidwa ndi mzere wa Silicon Photodiode kuti uwerengedwe.
Mitundu ya 2D imagwiritsidwa ntchito pojambula, kuphatikiza Medical(SPECT, PET, PET-CT, ToF-PET), SEM, kamera ya Gamma.Mitundu ya 2D iyi nthawi zambiri imaphatikizidwa ndi gulu la SIPM, gulu la PMT kuti liwerengedwe.Kinheng amapereka mndandanda wa 2D kuphatikizapo LYSO, CsI (Tl), LSO, GAGG, YSO, CsI (Na), BGO scintillator etc.
M'munsimu ndi kinheng a zambiri mapangidwe zojambula kwa 1D Ndipo 2D gulu makampani.
