Izisombululo zeNyukliya zoMfanekiso woNyango
Yintoni umfanekiso woNyango?
INyukliya yezonyango (ekwabizwa ngokuba yi-radionuclide scanning) sisixhobo esisebenzayo sokuxilonga kuba ayibonisi kuphela i-anatomy (isakhiwo) selungu okanye ilungu lomzimba, kodwa nomsebenzi welungu ngokunjalo.Olu "lwazi lusebenzayo" longezelelweyo luvumela iyeza lenyukliya ukuba likwazi ukuxilonga izifo ezithile kunye neemeko zonyango ezahlukeneyo ngokukhawuleza kunezinye iimvavanyo ze-imaging yezonyango ezibonelela ikakhulu ulwazi lwe-anatomic (isakhiwo) malunga nelungu okanye ilungu lomzimba.Amayeza enyukliya anokuba luncedo ekuxilongeni kwangoko, unyango, kunye nothintelo lweemeko zonyango ezininzi kwaye luyaqhubeka nokukhula njengesixhobo esinamandla sonyango.
KUNINZI LWAMAZIKO ONONOPHELO LWEMPILO abonelela ngolawulo lokuxilonga ngoxilongo lwezonyango oluye lwaba yinxalenye yobomi babo bemihla ngemihla kwiindlela zeradiology jikelele (okt, CT, MR, X-ray, PET, SPECT, njl.).Nangona kunjalo, iingcali kula maziko, ukusuka koogqirha, iteknoloji, kunye nabalawuli, ukuya kubasebenzi bePACS / IT, nabo baye bava intlungu yokungabi nezisombululo ezifanelekileyo ze-PACS kuluhlu lweendlela ezahlukeneyo.Ezona modali zingasetyenziswanga kakhulu yi-PACS ziimodali ze-nuclear molecular imaging modalities, kuquka i-PET-CT, i-SPECT-CT, i-nuclear cardiology, kunye neyeza lenyukliya ngokubanzi.
Nangona umfanekiso wemolekyuli yenyukliya incinci xa kuthelekiswa nenani leemviwo ezenziwa ngonyaka, ukubaluleka kwayo akufanele kujongelwe phantsi, ngokwezonyango nangokwemali.I-PET-CT ibonakaliswe ukuba yi-de facto modality xa kuziwa kukuxilongwa komhlaza.I-Nuclear cardiology ibe yindlela yokuzikhethela kwi-cardiology engahlaseli.Iyeza ngokubanzi lenyukliya libonelela ngosetyenziso lwemifanekiso esebenzayo ekungekho ezinye iindlela ezinokuhambelana.Ngokwemali, i-PET-CT kunye ne-nuclear cardiology zisephakathi kwezona nkqubo zibuyiswe kakhulu kwi-diagnostic imaging.
Yintoni eyenza umfanekiso wemolekyuli yonyango yenyukliya yahluke kwiimodali zeradiology jikelele kukuba imifanekiso yangaphambili iyimisebenzi yomzimba, ngelixa le yokugqibela ifanekisela i-anatomy yomzimba.Yiloo nto i-imaging ye-nuclear molecular imaging ngamanye amaxesha ikwabizwa ngokuba yi-metabolic imaging.Ukuze uhlalutye imisebenzi yomzimba kwimifanekiso efunyenweyo, izixhobo ezikhethekileyo zokujonga kunye nokuhlalutya zifunekayo.Ezi zixhobo zizo kanye zingekhoyo kuninzi lwePACS namhlanje.
Ngokubhekiselele koku, ngakumbi nangakumbi inkampani yetekhnoloji yokucinga yezonyango ifuna ukuphuhlisa esona sizukulwana sitsha i-PET, i-SPECT.
Kutheni ukhetha uKinheng:
I-1.I-pixel dimension encinci ekhoyo
2.Ukuncitshiswa kwe-optical crosstalk
3.Ulungelelwano oluhle phakathi kwepikseli ukuya kwipikseli/ Uluhlu kuluhlu
4.TiO2/BaSO4/ESR/E60 izibonisi ezikhoyo
5.Isikhewu sePixel: 0.08, 0.1, 0.2, 0.3mm
6.Uvavanyo lokusebenza olukhoyo

Uyilo lomatshini lokudibanisa:
Ngokusekwe kusetyenziso lokugqibela loluhlu oludityanisiweyo, zininzi iintlobo zoyilo lomatshini ukusuka eKinheng ukuhlangabezana neshishini lokuhlolwa kwezonyango kunye nokhuseleko.
Uluhlu lwe-1D Liner lusetyenziswa ikakhulu kushishino lohlolo loKhuseleko, olufana ne-Bagger scanner, iAviation scanner, i-3D scanner kunye ne-NDT.Izinto eziBandakanya iCsI(Tl), iGOS:Tb/Pr Film, GAGG:Ce, CdWO4 scintillator njl. Ngokuqhelekileyo zidityaniswe neSilicon Photodiode line array ukuze zifundwe.
Uluhlu lwe-2D ludla ngokusetyenziselwa ukwenza umfanekiso, kubandakanywa i-Medical(SPECT, PET, PET-CT, ToF-PET), i-SEM, ikhamera ye-Gamma.Ezi zintlu ze-2D zidityaniswa ne-SIPM uluhlu, uluhlu lwe-PMT ukuze lufundwe ngaphandle.I-Kinheng inikezela ngoluhlu lwe-2D kuquka i-LYSO, i-CsI (Tl), i-LSO, i-GAGG, i-YSO, i-CsI (Na), i-BGO scintillator njl.
Apha ngezantsi ngumzobo we-kinheng woyilo oluqhelekileyo lwe-1D kunye ne-2D yoluhlu lweshishini.
